CMX512-XL problems

Recommended Posts

I just built my computer with CMX512-XL (x2) and DFI nF4 Ultra-D motherboard and was trying to install windows. Blue screen popped up at random times. I looked through the forums and change the BIOS values that I can find. But that still doesn't solve the problem. Any other suggesion please?


Thank you very much!

Originally I have 2 rams installed in bank 2 and 4 (that's what the manual said). Now I installed the ram back to bank 1 and 2 and the blue screen doesn't pop up as much and let me finish the windows installation process. however, by installing the ram to bank 1 and 2, the BIOS has warning saying that I'm only using single channel (333 MHZ) and if I want to get double channel (400 MHZ) back, I'll need to change those back to bank 2 and 4 which gave me blue screens.

Please put the modules on either slots 1&3 or 2&4; make sure you have the latest BIOS installed for your MB (download the Beta version if possible), load optimized defaults settings and try the following BIOS settings;

TwinX512 or Twinx1024-3200XL

Genie BIOS/DRAM Configuration

DRAM Frequency Set: 2:1 or 400MHz or 200 (if option are 133/166/200)

Command per Clock: Enabled

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 2T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

And leave the rest at AUTO setting

Genie BIOS

FSB BUS Frequency: 200

LDT/FSB Frequency ratio: 5X

LDT Bus Transfer Width: 16 16

CPU/FSB Frequency ratio: Auto

PCI Ex: 100

K8 cool N’ quiet: Disable

CPU VID Start Up Value: 1.55

CPU VID Control: 1.55

CPU VID Special Control: Auto

Chipset Voltage Control: 1.6

DRAM Voltage Control: 2.8

All other settings are motherboards defaults

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!
