Twinx XMS 2x256 PC2700LL errors in memtest


Recommended Posts


I Bought Twinx XMS 2x256 PC2700LL one year and a half ago.

I always experienced random crashes and as I didn't know memetest, I didn't guess the memory could be faulty (last time I had faulty memory, Windows wouldn't start).

The memory is running on an A7N8X motherboard with an althlon XP 2600+

The memory is running at 333MHz with latencies 2-2-2-5 and dual channel.

I use no overclocking at all.


I runned memtest for a night and encountered several times errors at the same address in the memory, and also some other errors quite randomly in the memory.


Well, I think the modules are wrong and then need to be replaced.

So I need to get a RMA number.


I can perform more tests if required.

Thanks for reading, and thanks in advance for the answers.

Please load setup/optimized defaults and then set the following settings manually and test the modules one at a time with http://www.memtest.org to be sure.

CPU Freq: 166 MHz

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Resulting Frequency: 166MHz

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

If you do find you have a failing module then please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that might suggest some other problem, and I would suggest testing them in another system to be sure.
