Overview

Pentium II

The Pentium® II Processor is the follow-on to the Pentium® Processor. The Pentium

II Processor, like the Pentium® Pro processor, implements a Dynamic Execution micro-architecture -- a unique combination of multiple branch prediction, data flow analysis, and speculative execution. This enables the Pentium® II Processor to deliver higher performance than the Pentium

processor, while maintaining

binary compatibility with all previous Intel architecture processors. A significant feature of the Pentium

II Processor, from a system perspective, is the built-in direct multiprocessing support. In order to achieve multiprocessing, and maintain the memory and I/O bandwidth to support it, new system designs are needed. For systems with dual processors, it is important to consider the additional power burdens and signal integrity issues of supporting multiple loads on a high speed bus. The Pentium

II Processor card supports both uni-processor and dual processor

implementations. The Pentium

II Processor utilizes Single Edge Contact (S.E.C.) (Figure 1) cartridge packaging technology. The S.E.C. cartridge allows the L2 cache to remain tightly coupled to the processor, while maintaining flexibility when implementing high performance processors into OEM systems. The second level cache is performance optimized and tested at the cartridge level. The S.E.C. cartridge utilizes surface mounted core components and a printed circuit board with an edge finger connection. The S.E.C. cartridge package introduced on the Pentium

II Processor

will also be used in future Slot 1 processors. The S.E.C. cartridge has the following features: a thermal plate, a cover and a PCB

with an edge finger connection. The thermal plate allows standardized heatsink attachment or customized thermal solutions. The thermal plate enables a reusable heatsink to minimize fit issues for serviceability, upgradeability and replacement. The full enclosure also protects the surface mount components. The edge finger connection maintains socketabilty for system configuration. The edge finger connector is denoted as ‘Slot 1 connector’ in this and other documentation.

The entire enclosed product is called the Pentium

II Processor. The packaging technology and each of the physical elements of the product are referred to using accurate technical descriptions. This allows clear reference to the products as just a processor. This is the model used in past packaging technologies like PGA, TCP, PQFP, DIP, etc.

IntroductionEP-BXBS

S.E.C. Cartridge Terminology

• Pentium® II Processor The new enclosed card packaging technology is called a “Single Edge Contact cartridge.” This is similar to previous names for packaging technology such as PGA or TCP.

• Processor card The green PCB (with or without components on it)

• Processor core The silicon on the PLGA package on the PCB

• Cover The plastic cover on the opposite side from the thermal plate.

• Slot 1 The slot that the S.E.C. cartridge plugs into, just as the Pentium® Pro processor uses Socket 8.

• Retention mechanism Formerly ‘retention module’ the dual posts, etc. that holds the cartridge in place.

• Thermal plate The heatsink attachment plate.

• Heat sink supports The support pieces that are mounted on the mainboard to provide added support for heatsinks.

The L2 cache (TagRAM, PBSRAM) components keep standard industry names. The Pentium

II Processor is the first product to utilize the S.E.C. cartridge technol-

Accelerated Graphics Port (AGP or A.G.P.)

Typically, 3D graphics rendering requires a tremendous amount of memory, and demands ever increasing throughput speed as well. As 3D products for the personal computer become more and more popular, these demands will only increase. This will cause a rise in costs for both end users and manufacturers. Lowering these costs as well as improving performance is the primary motivation behind AGP. By providing a massive increase in the bandwidth available between the video card and the processor, it will assist in relieving some of these

pressures for quite sometime.

Hardware Monitoring

Hardware monitoring allows you to monitor various aspects of your systems operations and status. These include features such as CPU temperature, voltage and fan RPM’s.

Adaptec SCSI (Legacy/SE & Ultra-2 LVD)

The EP-BXBS mainboard features the advanced Adaptec AIC-7890 Ultra-2 Wide SCSI controller. This controller provides support for Low Voltage Differential (L VD) SCSI devices as defined under the Ultra-2 section of the SCSI-3 standard. LVD SCSI devices allow for data transfer rates of up to 80 Mbytes/sec and can use cable lengths of up to 12 meters! Additionally the AIC-3860 Adaptec controller is also provided for backwards compatibility with singleended (SE) legacy SCSI devices such as SCSI-1, Fast, Fast Wide, Ultra and Ultra W ide. Below is a chart summarizing the possible data-transfer rates available with SCSI.

Introduction EP-BXBS

Page 1-6

EP-BXBS Form-Factor

The EPoX EP-BXBS is designed with ATX form factor - the latest industry standard of chassis. The ATX form factor is essentially a Baby-AT baseboard rotated 90 degrees within the chassis enclosure and a new mounting configuration for the power supply. With these changes the processor is relocated away from the expansion slots, allowing them all to hold full length add-in cards. ATX defines a double height aperture to the rear of the chassis which can be used to host a wide range of onboard I/O. Only the size and position of this aperture is defined, allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output, joystick, modem, LAN, audio, etc.) to systems. This will help systems integrators differentiate their products in the marketplace, and better meet your needs.

• By integrating more I/O down onto the board and better positioning the hard

drive and floppy connectors material cost of cables and add-in cards is reduced.

• By reducing the number of cables and components in the system, manufacturing

time and inventory holding costs are reduced and reliability will increase.

• By using an optimized power supply, it's possible to reduce cooling costs and

lower acoustical noise. An ATX power supply, which has a side-mounted fan, allows direct cooling of the processor and add-in cards making a secondary fan or active heatsink unnecessary in most system applications.

ATX POWER SUPPLY

EP-BXBS Board

Power-On/Off (Remote)

The EP-BXBS has a single 20-pin connector for ATX power supplies. For ATX power supplies that support the Remote On/Off feature, this should be connected to the systems front panel for system Power On/Off button. The systems power On/ Off button should be a momentary button that is normally open.

The EP-BXBS has been designed with “Soft Off" functions. You can turn Off the system from one of two sources: The first is the front panel Power On/Off button, and the other is the "Soft Off" function (coming from the EP-BXBS’s onboard circuit controller) that can be controlled by the operating system. Windows 95/98 will control this when the user clicks that they are ready to Shutdown the system.

JP3:

NOTE: Based on the implementation of the Intel 440BX AGPset the EP-BXBS is able to provide two front side bus (FSB) frequencies -- either 66MHz or 100MHz for Slot 1 processors and memory operations. The mainboard will automatically detect the correct FSB and set accordingly unless JP100 is set otherwise (see jumper JP100 below). The primary and secondary processor slots both operate synchronously at either 66MHz or 100MHz FSB, therefore if two processors are used both will need to be of the same type and speed; otherwise the lower of the two FSB frequencies will be set. When using the 100MHz FSB you must use PC100 compliant SDRAM.

Memory is an important component of any 100MHz motherboard. When selecting memory for use on your EPoX brand motherboard we recommend using only the finest quality modules. EPoX would like to stress that using non-compliant PC100 SDRAM modules with a 100MHz FSB severely compromises the integrity of the system.

Section 3-2 System Memory Configuration

Memory Layout

The EP-BXBS supports (4) 168-pin DIMMs (Dual In-line Memory Module). The DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized DRAM). Do not mix EDO DIMM and SDRAM DIMM in the system.

• SDRAM DIMM may be 100 MHz (10ns) or 125 MHz (8ns) bus speed.

• SDRAM DIMM may be 8MB, 16MB, 32MB, 64MB, 128MB, or 256MB registered (see table 2).

• 100MHz FSB frequency requires PC100 compliant SDRAM memory.

• 4 clock SDRAM is recommended instead of 2 clock.

• If using 50ns and 60ns EDO DIMM together you must set BIOS for 60ns.

• Table 1 shows several possible memory configurations.

• Table 2 shows compatible SDRAM components types according to Intel

440BX datasheets. (Internet: http://developer.intel.com)

Section 3-3 Installing a Pentium II Processor

The EP-BXBS uses the Single Edge Contact (SEC) slot for a Pentium II processor packaged in an SEC cartridge. The SEC slot is not compatible with other nonPentium II processors.

Please have ready the following list of components so that we may install the processor onto the motherboard.

1. Heat sink support (top/bottom piece)

` 2. Pentium II processor heat sink & fan

3. Intel Pentium II Processor

OK, now that you have all of your components ready, we can start. Step 1. First, please refer to figue 8 below and follow the directions to lift up the

fixed foldable Pentium II retention mechanism. This pre-installed device is designed for you to install the Pentium II CPU more easier and to avoid any damage on the board due to overtightening the four screws.

Step 2. One thing must be kept in mind that please make sure to lift upright the foldable parts of the retention module to fit and install the CPU properly.

Figure 8

Step 3. Now we are going to install the heatsink support base piece (figure 9) onto the motherboard. There is both a large and small hole (figure 10) so that the base will only fit in one direction. This piece needs to be pushed into the holes firmly until it is seated.

Step 4. Now we are ready to install the SEC Cartridge (Pentium II Processor) into the Retention Module. The SEC Cartridge is mounted by sliding the SEC Cartridge into the Retention Module and letting it slide all the way down. Once it reaches the bottom make sure you press firmly on SEC cartridge to firmly secure into the Slot 1 Socket.

Section 3-5 External Modem Ring-in Power On and Keyboard Power On Function (KBPO)

External Modem Ring-in Power On

On the basis of the bounded functions of the I/O chipset, the two serial ports are able to support the External Modem Ring-in Power On Function. Once users connect an external modem to COM1 or COM2, the EP-BXBS mainboard allows the user to turn on their system by remote using dial-up software on another computer. Please refer to the BIOS Power Management Setup section for configuration instructions (page 4-15).

Keyboard Power On Function (KBPO)

The Keyboard Power-On (KBPO) function allows users to turn on a PC by easily touching the keyboard instead of bending down to look for the power button under a table. To enable this feature please follow the steps below.

Step 1:When power to the system off set JP13 to the 1-2 position.

Step 2:Push the momentary switch to turn on the system and then push again (hold

for 4 seconds) to turn the system off. Step 3:Keyboard power on is now enabled. You can enjoy KBPO by pressing any

1 key, Hot key (Ctrl-F1, F2...F12), or entering a password (maximum of 5 characters) to turn on the system. The BIOS default is a hot key of <Ctrl>-<F1> to turn on the system. Your system will turn on automatically after releasing the keys. To power off the system you can use the soft-off function under Windows 95/98 or use the momentary switch.

Notes: Intel ATX version 2.0 specification recommends the use of a power supply with 0.72A (720mA) in the +5.0vsb. With our EP-BXBS mainboard, the 5.0vsb (standby) power has to be >= 0.1A (100mA) to enjoy this unique benefit. However, ATX power supplies with less than 0.1A can still be used in the system but KBPO must be disabled.

Section 3-6 Adaptec SCSI Setup

Introduction

The EP-BXBS mainboard features the advanced Adaptec AIC-7890 Ultra-2 Wide SCSI controller . This controller provides support for Low V oltage Differential (L VD) SCSI devices as defined under the Ultra-2 section of the SCSI-3 standard. L VD SCSI devices allow for data transfer rates of up to 80 Mbytes/sec and can use cable lengths of up to 12 meters! Additionally the AIC-3860 Adaptec controller is also provided for backwards compatibility with single-ended (SE) legacy SCSI devices such as SCSI-1, Fast, Fast W ide, Ultra and Ultra W ide.

Hardware Setup and Connector Descriptions

The motherboard can have attached a total of 15 SCSI devices. The 15 devices can be a combination of LVD Ultra-2 devices and/or SE Legacy devices but note that the SE Legacy controller can support up to 8 devices only!

Provided on the motherboard are three SCSI connectors. The first two being SCJ1 and SCJ2 are provided for single-ended (SE) legacy SCSI devices and will operate at a data transfer rate of 40 Mbytes/sec (max.) using the 68-pin “W ide” connector and 20 Mbytes/sec (max.) using the 50-pin “Narrow” connector. It is strongly recommended that all legacy SCSI devices be connected to either one of these two connectors. Due to the design characteristics of SE mode devices the cable length per connector should never exceed 3 meters with up to 4 SCSI devices and 1.5 meters with up to 8 SCSI devices.

External SCSI devices can be connected to the SCSI bus through the use of the included “external SCSI-2 port adapter .” T o use external SCSI devices simply use onboard connector SCJ2 with an internal 50pin SCSI cable. One end of the cable must attach to SCJ2 and the other end connects to the external port adapter. Internal SCSI devices can still be used, but just not on the ends of the cable.

Installation EP-BXBS

Page 3-14

The last connector labeled SCJ3 is a single 68-pin “W ide” connector for L VD mode SCSI devices operating at a maximum data transfer rate of 80 Mbytes/sec. The maximum cable length that can be used is 12 meters with up to 15 SCSI L VD devices. It is strongly recommended that no single-ended (SE) legacy SCSI devices be used on this connector as performance will drop to a 40 Mbytes/sec maximum with device and cable length limitations of the above first two connectors!

SCSI Bus Termination

Proper operation of the SCSI bus requires the following: each device must have a unique SCSI ID (including the SCSI controller) and the SCSI chain must have termination on each of the 3 onboard connectors. Termination is required at the last device on each SCSI cable.

Termination for the majority of devices are accomplished by enabling a jumper or terminator resistor. No terminator is required for the SCSI controller onboard the motherboard as this will be set automatically. When using the “external SCSI-2 port adapter” the external SCSI device must provide termination.

The Ultra-2 (LVD) cable is provided with a terminator which attaches to the end of the cable.

AWARD BIOS SETUP

BIOS Instructions

Award’s ROM BIOS provides a built-in Setup program which allows users to modify the basic system configuration and hardware parameters. The modified data will be stored in a battery-backed CMOS, so that data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM will stay unchanged unless there is a configuration change in the system, such as hard drive replacement or a device is added.

It is possible for the CMOS battery to fail, this will cause data loss in the CMOS only. If this does happen you will need to reconfigure your BIOS settings.

To enter the Setup Program :

Power on the computer and press the <Del> key immediately, this will bring you into the BIOS CMOS SETUP UTILITY.

Figure 1: CMOS Setup Utility

BIOS EP-BXBS

Page 4-2

The menu displays all the major selection items. Select the item you need to reconfigure. The selection is made by moving the cursor (press any direction key ) to the item and pressing the ‘Enter’ key. An on-line help message is displayed at the bottom of the screen as the cursor is moved to various items which provides a better understanding of each function. When a selection is made, the menu of the selected item will appear so that the user can modify associated configuration parameters.

4-1 Standard CMOS Setup

Choose “Standard CMOS Setup” in the CMOS SETUP UTILITY Menu (Figure 2). The Standard CMOS Setup allows the user to configure system settings such as the current date and time, type of hard disk drive installed, floppy drive type, and display type. Memory size is auto-detected by the BIOS and displayed for your reference. When a field is highlighted (use direction keys to move the cursor and the <Enter> key to select), the entries in the field can be changed by pressing the <PgDn> or the <PgUp> key.

Figure 2: Standard CMOS Setup

NOTE: If the hard disk Primary Master/Slave and Secondary Master/Slave are set to Auto, then the hard disk size and model will be auto-detected. NOTE: The “Halt On:” field is used to determine when to halt the system

4-5 PNP/PCI Configuration

The PNP/PCI configuration program is for the user to modify the PCI/ISA IRQ signals when various PCI/ISA cards are inserted in the PCI or ISA slots.

WARNING: Conflicting IRQ’s may cause the system to not find certain devices.

Figure 6: PCI Configuration Setup

PNP OS Installed: Do you have a PNP OS installed on your system. The default is No.

BIOS EP-BXBS

Page 4-18

Resources Controlled By: Allows manual setting of resources or automatic by the PNP BIOS. The default is Manual.

Manual: PNP Card’s resources will be controlled manually. You can set which IRQ-X and DMA-X are assigned to PCI/ISA PNP or Legacy ISA Cards. Auto: If your ISA card and PCI card are all PNP cards, BIOS will assign the interrupt resource automatically.

Reset Configuration Data: This setting allows you to clear ESCD data. The default is Disabled

Disabled: Normal Setting. Enabled: If you have plugged in some Legacy cards to the system and they

were recorded into ESCD (Extended System Configuration Data), you can set this field to Enabled in order to clear ESCD.

IRQ-3 to IRQ-15 assigned to: These settings allow IRQ’s to be reserved for Legacy ISA device use exclusively or be available for use with PNP devices. These options are only displayed if “Resources Controlled By” is set to manual.

DMA-0 to DMA-7 assigned to: These settings allow DMA’s to be reserved for Legacy ISA device use exclusively or be available for use with PNP devices. These options are only displayed if “Resources Controlled By” is set to manual.

Used MEM base addr: The Used MEM base addr (CB00, CC00, D000, D400, D800, DC00) and Used MEM Length (8K, 16K, 32K, 64K) are used to support some specific ISA Legacy cards with requested memory space below 1M address. Now with these two functions, users can define where the used memory address is located and its length of the legacy area that is used by the legacy device to avoid the memory space conflict. For example, if you select “D000” for Used MEM base addr” and “16K” for “Used MEM Length”, that means the address region D000HD3FFFH is occupied by ISA legacy cards, and thus BIOS will not assign this region for PnP/ISA and PCI cards. The default is N/A.

Assign IRQ for USB: This item allows the BIOS to assign an IRQ to the USB controller. If no USB devices are used in the system this can be set to “disabled” to free an IRQ for other uses. The default is Enabled

Disabled: Release IRQ for other device. Enabled: Provides IRQ for USB device.

4-9 IDE HDD Auto Detection

The “IDE HDD auto detection” utility is a very useful tool, especially when you do not know which kind of hard disk type you are using. You can use this utility to detect the correct disk type installed in the system automatically. But now you can set HARD DISK TYPE to Auto in the STANDARD CMOS SETUP. You don’t need the “IDE HDD AUTO DETECTION” utility. The BIOS will Auto-detect the hard disk size and model on display during POST.

Figure 8: IDE HDD Auto Detection

NOTE: HDD Modes

The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NORMAL mode

BIOS EP-BXBS

Page 4-26

Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing.

The maximum number of cylinders, head & sectors for NORMAL mode are.

1024, 16 & 63 no. Cylinder (1024) x no. Head ( 16) x no. Sector ( 63) x no. per sector ( 512)

528 Megabytes

If user set his HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that!

LBA (Logical Block Addressing) mode: A new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD. During HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder into its own physical address inside the HDD. The maximum HDD size supported by LBA mode is 8.4 GigaBytes which is obtained by the following formula:

no. Cylinder (1024) x no. Head ( 255) x no. Sector ( 63) x bytes per sector ( 512)

8.4 GigaBytes

LARGE mode: Extended HDD access mode supported by Award Software. Some IDE HDDs contain more than 1024 cylinder without LBA support (in some

cases, user do not want LBA). The Award BIOS provides another alternative to support these kinds of LARGE mode.

CYLS HEADS SECTOR MODE

1120 16 59 NORMAL 560 32 59 LARGE

BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by dividing it by 2. At the same time, the number of heads is multiplied by 2. A reverse transformation process will be made inside

BIOSEP-BXBS

Page 4-27

INT 12h in order to access the right HDD address! Maximum HDD size:

no. Cylinder (1024) x no. Head ( 32) x no. Sector ( 63) x bytes per sector ( 512)

1 GigaByte

Note: To support LBA or LARGE mode of HDDs, there must be some software involved. All the software is located in the Award HDD Service Routine (INT 13h). It may fail to access a HDD with LBA (LARGE) mode selected if you are running under a Operating System which replaces the whole INT 13h.

UNIX operating systems do not support either LBA or LARGE and must utilize the Standard mode. UNIX can support drives larger than 528MB.

4-10 HDD Low Level Format

Interleave: Select the interleave number of the hard disk drive you wish to perform a low level format on. You may select from 1 to 8. Check the documentation that came with the drive for the correct interleave number, or select 0 for automatic detection.

Auto scan bad track: This allows the utility to scan first then format by each track. Start: Press<Y>to start low level format.

4-11 Save & Exit Setup

The “SAVE & EXIT SETUP” option will bring you back to the boot up procedure with all the changes you just recorded in the CMOS RAM.

4-12 Exit Without Saving

The “EXIT WITHOUT SAVING” option will bring you back to normal boot up procedure without saving any data into CMOS RAM.

All old data in the CMOS will not be destroyed.

Reset SCSI Bus at IC Initialization: If the SCSI BIOS is enabled, it will reset the SCSI bus when the computer is rebooted then scan for SCSI devices. This option specifies whether the BIOS will wait 2 seconds after the reset of the bus before scanning for SCSI devices. The default is Enabled.

Enabled: Delay 2 seconds. Disabled: No delay.

Extended BIOS Translation for DOS Drives > 1 GByte: To support disk drives larger than 1GB, the SCSI BIOS can include an extended translation scheme. This will allow support of disk drives as large as 8GB under DOS. W ith extended translation enabled, drives handled by the SCSI BIOS will use extended translation if their formatted capacity is greater than 1GB, and drives smaller than 1GB will use standard translation. Note that all data on attached disk drives will be lost if the translation scheme is changed after installation. Use extended translation only with MSDOS, Windows 95/98, Windows NT (FAT), and OS/2. Do not enable this option if using NetWare or Unix. The default is Enabled.

Options: Enabled and Disabled.

Host Adapter BIOS: This option will enable or disable the SCSI BIOS. Note that the SCSI BIOS must be enabled if you want the computer to boot from a SCSI drive. Also many SCSI features require the SCSI BIOS to be enabled. The following features will not function if the SCSI BIOS is disabled: Support Removable Disks

Under BIOS as Fixed Disks, Extended BIOS Translation for DOS Drives >1GB, Display <Ctrl><A> message During BIOS Initialization, BIOS Support for Bootable CD-ROM, and BIOS Support for Int13 Extension.

The default is Enabled.

Options: Enabled and Disabled.

Support Removable Disks Under BIOS as Fixed Disks: This option specifies whether removable-media drivers are supported by the SCSI BIOS. If a removablemedia drive is handled by the BIOS, do not remove the media while the drive is on as you might lose data. The default is Boot Only.

Boot Only: Removable-media drives will be considered fixed hard drives only during boot. After system is fully booted then the media may be removed safely.

SCSIEP-BXBS

Page 5-7

All Disks: Removable-media drives will be considered fixed hard drives at all times and should never have their media removed. Disabled: Removable-media drives will never be considered fixed drives by the BIOS and cannot be booted from.

Options: Enabled and Disabled.

5-5 SCSI Disk Utilities

This menu, when selected, will scan the SCSI bus to determine the drives installed and will display a list of all the IDs and drive descriptions. Once the list is displayed you have two options available for the devices: Format Disk and Verify Disk Media.

Figure 7: SCSI Disk Utilities

SCSI EP-BXBS

Page 5-8

Format Disk: Before any disk drive can be setup by the operating system it must have a low-level format. Most SCSI devices are preformatted thus this option is not necessary. Use this option to perform a low level format on the drive. A low-level format destroys all data on the drive and cannot be aborted once the procedure starts. This option is only applicable for disk drives (hard drives).

Verify Disk Media: This option will scan the selected drive’s media for defects. If any bad areas are found you will be prompted to reassign them so they will no longer be used. Press <Esc> at any time to abort this utility. This option is only applicable for disk drives (hard drives).

CPU Clock Frequency selection in BIOS

There is a special function available in the BIOS to adjust the CPU bus frequency. This allows the external clock to be modified depending upon what FSB has been selected. For more information about selecting the FSB please see page 3-4. Once you know what FSB is being used (66 or 100MHz) then it can be modified as follows:

66MHz FSB options: 66.8 (default), 68.5, 75, and 83MHz. 100MHz FSB options: 100 (default), 103, 112, and 133MHz.

To modify the FSB follow the steps below:

1. Enter the BIOS CMOS utility by pressing the <Del> key during boot.

2. Choose “Chipset Features Setup.”

3. Select the option named “CPU Host Clock” and use the <Page Up> and <Page Down> keys to select the desired frequency.

4. “Save and Exit setup” to complete the BIOS setting.

If the system can no longer boot after the above settings then you processor is not supporting the modified frequencies. Use the following steps below to recover the system:

1. Power the system off.

2. Press the <In> (insert) key while powering the system on. The system will now power on using the default FSB.

3. Follow the steps above to modify the FSB and try again.

Warning: We do not guarantee CPUs will support modified fequencies. Frequency use depends upon CPU design and the peripherals you are using; it’ s vitally important to use faster peripherals (faster SDRAM, I/O cards, etc) to support the higher frequencies.
