Bad CMX512RE-3200LL stick

[sambrookjm]

Two years ago, I purcahsed a PC from Monarch Computers, Inc. The PC was an Athlon 64 FX-51, with two 512MB CMX512RE-3200LL sticks for memory. Until a couple of weeks ago, everything was working fine. At that time, I started getting some random lock ups, and some random reeboots. I spoke with a friend of mine, who suggested a number of solutions. One of these solutions was to remove the memory sticks one at a time, and see if either of those had gone bad. I pulled one of them out, and within an hour my machine rebooted. I then took the other stick out, and my PC has not had any of the random reboots or lockups since. I can only assume that the stick has gone bad, and was wondering if it was still covered under warranty. If so, are there any other tests that I would need to run (or other information that you would need) to diagnose the chip?

 

The label on the chip has the following text printed on it:

CMX512RE-3200LL XMS3200REv1.1

0349086

 

XMS3200 512MB 400 MHz 2326

 

Thanks for your help in this matter.

Please load setup/optimized defaults and then set the Dim Voltage to 2.7X volts (+.2 Volts W/Giga-Byte) and then set the timings manually to the tested settings for the specific module you have, XMS2700C2 Cass 2-3-3-6 for example or if you have Value Select "BY SPD" and then test the module/'s one at a time with http://www.memtest.org! If you still get errors, 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 test them in another system or MB to be sure.

Setting the Voltage back seems to have done the trick, although for the life of me I can't explain why the other DIMM was giving me errors when it was in there alone. :confused: I'm also rather curious as to how the voltage settings got changed as well...but for now, things seem to be working. Thanks for the help.

 

I've got a follow-up question, though. Before I found out about your warranty, I purchased another DIMM of the same type (CMX512RE-3200LL) This one looks like it is v2.1, instead of the v1.1 that I have in my machine now. When I ran the Memtest 86+ with one of the old ones and one of the new ones (after the DIMM voltage had been set to 2.7V), I was receiving literally thousands of errors. In addition, the newer DIMM was very, VERY hot to the touch. Do the newer versions of the DIMM run at a lower voltage than the older ones?
