Pentium 4 processor Up to 2.4A GHz 400 MHz 512 KB
Pentium 4 processor Up to 2.53 GHz 533 MHz 512 KB
The list of supported processors for the desktop boards D850EMD2/D850EMV2 is available from
Intel’s World Wide Web site. All supported onboard memory can be cached. See the processor’s
data sheet for cachability limits.
®
Desktop Board D850EMD2/D850EMV2 Specification Update for the most up-to-date
CAUTION
Use only an ATX12V-compliant power supply with these desktop boards. ATX12V power supplies
have two power leads that provide required supplemental power for the Intel Pentium 4 processor
and the Intel 850E chipset. Always connect the 20-pin and 4-pin leads of the ATX12V power
supply to the corresponding connectors on the board. Otherwise, the board and the processor
could be damaged.
Do not use a standard ATX power supply. Doing so could damage the board and the processor.
For information about Refer to
Processor support Section 1.3, page 18
Processor usage Section 1.3, page 18
Power supply connectors Section 2.8.2.3, page 60

Product Description
1.7 System Memory
CAUTION
Turn off the power and unplug the power cord before installing or removing RIMM modules.
Failure to do so could damage the memory and the board. (After AC power is removed, the
standby power indicator LED should not be lit. See Figure 11 on page 45 for the location of the
standby power indicator LED.)
NOTE
✏
The desktop boards D850EMD2/D850EMV2 support combinations of no more than 32 RDRAM
components per RDRAM bank. If the total number of RDRAM components installed in all RIMM
sockets exceeds 64, the computer will not boot.
1.7.1 Memory Features
The 82850E MCH integrates two lock-stepped Direct Rambus banks, providing a processor-tomemory bandwidth up to 3.2 GB/sec. The desktop boards D850EMD2/D850EMV2 have four
RIMM sockets (two sockets for each bank) and support the following memory features:
• Single- or double-sided RIMM configurations
• Maximum of 32 Direct Rambus devices per bank
• Memory configurations from 128 MB (minimum) to 2 GB (maximum), using 128 Mbit or
256 Mbit technology PC800-compliant RDRAM
• Serial Presence Detect (SPD)–based configuration for optimal memory operation
• Suspend to RAM support
• ECC and non-ECC support
1.7.2 Continuity RIMM Modules
All RIMM sockets must be populated to achieve continuity for termination at the Rambus
interface. Continuity RIMMs (or “pass-through” modules) must be installed in the second
RDRAM bank if memory is not installed. If any of the RIMM sockets are not populated, the
computer will not complete the Power-On Self-Test (POST) and the BIOS beep codes will not be
heard.
23
Intel Desktop Board D850EMD2/D850EMV2 Technical Product Specification
1.7.3 RDRAM Memory Configuration
When installing memory, note the following:
• The four RIMM sockets are grouped into two banks:
Bank 0 (labeled on the board as RIMM1 and RIMM2)
Bank 1 (labeled on the board as RIMM3 and RIMM4)
• Bank 0 must be populated first, ensuring that the RDRAM installed in RIMM1 and RIMM2 is
identical in speed, size, and density. For example, the minimum system configuration would
use two 64 MB RIMM modules of PC800 RDRAM.
• If the desired memory configuration has been achieved by populating Bank 0, then Bank 1
should be filled with two Continuity RIMMs.
• If memory is to be installed in Bank 1, the RIMM modules installed in RIMM3 and RIMM4
must be identical in size and density to each other and match the speed of the RIMM modules
in Bank 0. The RIMM modules do not, however, need to match those in Bank 0 in size and
density. For example, if Bank 0 has two 128 MB RIMMs of PC800 RDRAM, Bank 1 would
require PC800 RDRAM also; however, any other supported RIMM modules such as 64 MB or
192 MB could be used.
• If ECC functionality is required, all installed RIMM modules must be ECC compliant.
Table 6 gives examples of RDRAM component density for various RIMM modules. Component
density (counts) can be identified on the RIMM label.

CAUTION
If the installed processor operates with a 533 MHz system bus, use only PC800-40 memory; do not
use PC800-45 memory. Failure to follow this guideline may result in unreliable operation. If the
installed processor operates with a 400 MHz system bus, you can use either PC800-40 or
PC800-45 memory. Table 7 lists the supported combinations of memory types with processor
system bus values.

NOTE
✏
The AGP connector is keyed for 1.5 V AGP cards only. Do not attempt to install a legacy 3.3 V
AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V AGP cards.
The AGP connector supports AGP add-in cards with 1.5 V Switching Voltage Level (SVL).
Legacy 3.3 V AGP cards are not supported and will prevent the system from booting if installed.
For information about Refer to
The location of the AGP connector Figure 1, page 14
The signal names of the AGP connector Table 40, page 67
AGP is a high-performance interface for graphics-intensive applications, such as 3-D applications.
While based on the PCI Local Bus Specification, Rev. 2.1, AGP is independent of the PCI bus and
is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of
the PCI bus related to handling large amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide memory access latency
• Demultiplexing of address and data on the bus for nearly 100 percent efficiency
For information about Refer to
The Accelerated Graphics Port Interface Specification Section 1.5, page 19
1.8.2 USB
