One faulty address


Recommended Posts

In january 2004 I bought a TWINX1024-3200C2PT memory set. Everything worked well, until some weeks ago. I suspected it had to do something with my memory, so I ran the memtest program. Several times per individual test it records an error on address 0002be23a20; it seems the fifth hexadecimal digit is stuck on "7". I took out the corresponding module and now everything seems to be fine. I didn't change any BIOS settings, and the other module works perfectly.


The other system specs:


DFI Lanparty NFII Ultra B

Athlon XP 2800+ (Barton)

Radeon 9800Pro

Some harddisks, cd/dvd drives,

a 550W PSU and enough

cooling for a nucleair reactor.


What should I do?


<edit> My retailer can't help me because their warranty period of one year has passed. </edit>


Thanks in advance,

I already removed the second (faulty) module which was in DIMM #3, and was operating under exactly the same settings.

Please test the modules one at a time with http://www.memtest.org and I would set the Dim Voltage to 2.7 Volts as well. If you do find one failing then lets get it or them replaced. 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 would suggest some other problem. And I would try testing the memory in another system to be sure.
