JohnWilliamson Posted November 22, 2004 Share Posted November 22, 2004 I believe one of the matched Twinx modules is defective. I am running 1GB of RAM in a server (my small business assembled) with an Intel Entry Server Board S875WP1-E with one CPU (P4 2.8g, 800mhz bus, 512mb L2) running Windows Server 2003 Enterprise. The server is on a UPS. After running without problems for several months, I began to encounter numerous STOP errors (specifically citing PFN_LIST_CORRUPT, IRQL_NOT_LESS_OR_EQUAL). I attempted to repair Windows Server 2003, but it repeatedly returned to a BSOD with the STOP errors. I removed one stick of Corsair Twinx memory and the problems continued. I removed the remaining stick and reinstalled the first stick, and the problems disappeared. Windows Server now loads correctly on 512 MB. Can you provide an RMA number and instructions how to proceed? Can I get another matched pair of Twinx to replace this one? Thanks, John Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 23, 2004 Corsair Employees Share Posted November 23, 2004 Please use this as a reference, but before making the necessary changes on your BIOS, please make sure that you have the latest BIOS installed: TwinX1024 or TwinX512-3200LL CPU Freq: 200 MHz Dim Voltage: 2.75 Volts DRAM Clock: 200 MHz/1:1/100% SDRAM CAS Latency: 2T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 2T SDRAM Active to Precharge Delay (tRAS): 6T CPC Override: Disabled AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!* 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! Link to comment Share on other sites More sharing options...
JohnWilliamson Posted November 25, 2004 Author Share Posted November 25, 2004 OK. As you suggested, I successfully updated my Intel BIOS to the latest, version 17, and confirmed that all timings are as you specified. Then, I ran MemTest86. On the good stick, I got no errors in three passes. On the other stick, I've received 12,751 errors in the first pass (still running). I also ran the Intel Platform Confidence Test without error using the good stick of memory. This would seem to indicate that there are no board issues either. So, what are my instructions for getting a new pair of TwinX delivered? My server is operational with 512MB right now and I don't want to have it completely off line while I wait for the exchange shipments to occur. I'd like to hang on to the good stick until the new pair arrive, then return the old bad & good sticks. Is this possible? BTW, have a good Thanksgiving.

JohnWilliamson Posted November 26, 2004 Author Share Posted November 26, 2004 Gee, what a deal. Even Linksys does it for routers. Sure glad we paid that premium for Corsair memory! Link to comment Share on other sites More sharing options...
