Bad memory module?


Recommended Posts


I have 2 CMX256a-2700LL Corsair RAMs (333mhz), in TwinX!


I have a Abit KV7 board with an Barton 3000+, 333Mhz.


Now some errors occured:

I was installing windows, and he couldnt read a file, after he retried it he was sometimes able to read it, sometimes not.


In Windows i played Doom3, and he hung up very fast, in Unreal 2 he took a bit longer, he hungs up in nearly every game, also when i do alot in windows.


I ran a mem-test and he said that there were 5000 bad bytes, in every of that bye the 2. bit was wrong.

he found that 5000 bad bytes in both RAMs


i am really confused about that cause i dont know why both RAMs should be defect! Now with an other 512MB Ram its working fine!

should i send the RAMs back to Corsair?

Please make sure that you have the latest BIOS for your MB and load Setup/Optimized default settings, and try the following BIOS settings;

TwinX1024 or TwinX512-2700LL

Advanced Chipset Features

CPU Freq: 166 MHz (333 FSB)

System Performance: User Define

Memory Frequency/CPU/DRAM ratio: 100%/1:1

Resulting Frequency: 166 MHz (333 FSB)

Memory Timing: User Define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 6T

DDR Reference Voltage: 2.7 Volts

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

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!
