The memory controller can not keep up with the extra DRAM at the rated 6400 speed. You will need to drop the speed of the DRAM from 800Mhz to 667Mhz. If you had purchased 4 X 1024MB of PC8500 (1066Mhz) DRAM, then you would have had to drop to PC6400 (800MHz) DRAM, etc. 2 X 2048 will not issue this problem. This is a problem of all 4 banks being populated.


So, enter your BIOS Setup Utility and set your DRAM Bandwidth from 800Mhz to 667Mhz.






JumperFree Configuration

AI Tuning = Manual

Overclock Options = Disabled


System Clocks

NB PCI-e Frequency (MHz) = 100


Voltage Control

Vcore Voltage = Auto

Memory Voltage = 2.0v

NB Core Voltage = 1.393


FSB & Memory Config


FSB - Memory Clock Mode = Unlinked

FSB - Memory Ratio = 4:5

FSB (QDR) = 266




Memory Timing Setting

tCL = 5

tRCD = 5

tRP = 5

tRAS = 12

Command Per Clock = 2 Clocks

tRRD = Auto

tRC = Auto

tWR = Auto

tWTR = Auto

tREF = Auto

tRD = Auto

tRFC = Auto

Async Latency = Auto

CPU Spread Spectrum = Auto

PCIE Spread Spectrum = Auto

SATA Spread Spectrum = Auto

LDT Spread Spectrum = Auto

LDT Frequency = 5x


USB Configuration

USB Controllers = Enabled

USB Legacy Support = Disabled (Disable when you memtest. Enable afterwards if you have usb keyboard)

USB 2.0 Controller = Enabled



Download memtest from http://www.memtest.org and extract the ISO image. Burn the ISO image to an CD-ROM disk. Boot to the optical drive with the memtest disk and allow for two full passes.

1. system stil works good without bsod,


2. but got a question is it true, that if you run 4 modules of 1 ghz and youre proc Q 6600 runs at 1066 mzh that its diveded by 2 that it runs max at 533 mzh at a slot, so you dont need memory at 800 mzh??

Today the system crashed 2ce and it was hard to start again. had to take the battery from the motherboard. Got an other question is it better to have 2 modules off 2ghz instead 4 off 1ghz? Otherwise i buy new ones i hate these crashes.


And would you then recommend the twin2x2048 6400C4 pro??
