1 stick of my TwinX died


Recommended Posts


AMD 2400 xp+

asus a7n8x

Corsair XMS Twinx cmx256a-2700llpt 2x256

sapphire radeon 9600 pro 128

running under win xp



anyway originally i was getting alto fo random crashes then eventually it refused to even start up past the black screen with the windows xp logo on it


so i reformatted and it wouldnt even reinstall.


then i removed one of my ram chips and everythign worked perfectly for liek 2 weeks (to finish school with a stable system). Now that I tried to put my other ram chip back in the computer would refuse to start at all again. so i ran metest first on the good chip

both tests at 2 2 2 5

good chip

2 errors

bad chip

400k errors @ only 50% complete


so I think that the one chip ios probably broken how do i go about returning it?

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 TwinX512-3200LL

CPU Freq: 133 MHz (266 FSB)

System Performance: User Define

Memory Frequency: 125%

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!

Okay so I did the tests that you asked for at the stated values.


and the stick that i think is still good ran 9 full passes and had 14 errors


the stick that i think is bad ran i full pass and had nearly 4 million errors!


so now whats the next step? do I get an RMA #?

Getting errors with both modules might suggest some other problem, but lets try replacing your modules. Please send us a email with a copy of the form or all of your info name address and phone# and the Module part# and copy the link to this post and email it to Warranty@corsairmemory.com. Or you can also use the On Line RMA Request Form as well.

If after 1 day or 24 hours excluding weekends you do not get the rma please email the same to rma@corsairmemory.com and we will help to resolve it.
