INTRODUCTION
Introduction
Product Description
The MB935 LGA 775 Pentium
Q35 chipset that can utilize a single LGA775 processor of up to 4.0GHz
or higher and supports FSB frequency of 800/1066 Mhz/1333Mhz
200MHz (800MT/s), 266MHz (1066MT/s), and 333MHz (1333MT/s)
HCLK respectively.
The Q35 chipset is designed for use with the Core.2 processor family,
including a faster 1333 MHz system bus. The integrated GMCH
component provides the CPU interface, DDR2 interface, Hub Interface.
Four DDR2 memory sockets support DDR2 667/800 SDRAM DIMM
modules of up to 8GB in capacity.
The board is designed with six Intel 82574L PCI Express Gigabit LAN
controllers. Four Serial-II ATA connectors offer 3Gb/s data throughput
speed - faster than the most advanced parallel ATA.
Additional expansion is provided by two PCI slot if the board is used
with the IP325 backplane bridge board. Other advanced features include
four USB 2.0 ports, digital I/O, four serial ports, and watchdog timer
function. Dimensions of the board are 13.98” by 7.28”.
Remarks:
MB935 supports the Intel Core 2 Duo and Intel C ore 2 Quad processors
and Intel Celeron 400 (Conroe-L) Sequence processor.

INSTALLATIONS
Installing the CPU
The MB935 motherboard supports an LGA 775 processor socket for
Intel Core 2 Duo and Intel Core2 Quad processors, and Intel Celeron
400(Conroe-L) Sequence processor.
The LGA 775 processor socket comes with a lever to secure the
processor. Refer to the pictures below, from left to right, on how to place
the processor into the CPU socket. Please note that the cover of the
LGA775 socket must always be installed during transport to avoid
damage to the socket.

INSTALLATIONS
ATX Power Installation
The system power is provided to the motherboard with the ATX1 and
ATX_12V power connectors. ATX1 is a 24-pin power connector and
ATX_12V is a 8-pin 12V power connector.
The 24-pin power connector can to be connected to a standard 20-pin
ATX power connector in a standard ATX power supply (Min. 400watt).
Note: The power supply 5VSB voltage must be at least 2A.
Installing the Memory
The MB935 motherboard supports four DDR2 memory sockets for a
maximum total memory of 8GB in DDR memory type. It supports
DDR2 667/800.
Basically, the system memory interface has the following features:
Supports two 64-bit wide DDR data channels
Available bandwidth up to 6.4GB/s (DDR2 800) for single-channel
mode and 12.8GB/s (DDR2 800) in dual-channel mode.
Supports 256Mb, 512Mb, 1Gb DDR2 technologies.
Supports only x8, x16, DDR2 devices with four banks
Supports only unbuffered DIMMs
Supports opportunistic refresh
Up to 32 simultaneously open pages (four per row, four rows
maximum)
Dual Channel Memory Configuration
If you want to operate the Dual Channel Technology, please note the
following explanations due to the limitation of Intel chipset
specifications.
1. Dual Channel mode will not be enabled if only one DDR II memory
module is installed.
2. To enable Dual Channel mode with two or four mem ory modules (it is
recommended to use memory modules of identical brand, size, chips,
and speed), you must install them into DIMM sockets of the same color.
The following is a Dual Channel Memory configuration table:
