Bad TWINX1024-3200XLPT 1GB Kit DDR400?

[Tolkienboy]

Hi, I purchased a Corsair TWINX1024-3200XLPT 1GB Kit DDR400 XMS3200 about 2-3 months ago and have finally come to the conclusion that I have a bad pair RAM. I have used Corsair many times before, and have never had a problem so I was slow to accept this conclusion. When I first got it I didn't notice any problems for a few weeks. Then I installed some high end 3d games such as BF1942, Far Cry, UT2004, and some others. Once in a while while playing these games, I would crash to blue screen saying I had a PFN_LST_CORRUPT error or that I had another type of memory error and if it occured again I should run tests. It only happened a couple of times and I didn't think that much of it, thought it was just a software glitch or some bad drivers. Then I started getting it randomly while surfing the web or just doing nothing. Sometimes I would leave my comp on and would come back an hour or two later and it would have crashed and restarted. Recently it has been happening more frequently and after checking all my drivers, I thought it might be the memory. I crash from this while playing 3d games at least 2 or 3 times a week now. I downloaded and ran Memtest today and I got an error after only 100 cycles, which seems pretty bad, since I've been told it often takes a full night to find memory errors. Here is my setup:

 

Mobo: MSI 865PE Neo2-FIS2R, latest bios version (can't remember number)

CPU: Pentium 4 3.0Ghz 800 FSB w/Northwood Core and HT

Vid Card: HIS Radeon 9800 Pro IceQ

Sound Card: SB Audigy2 ZS

HD: Dual Hitachi Deskstar 160GB SATA 7200 RPM drives, Non RAID

PSU: Thermaltake PurePower Butterfly 480w w/Active PFC

 

the sticks are set up in dual channel DDR with no special settings or overclocking at all. The bios settings are set to detect by SPD, and the voltages and frequencies are all stock. The case is very cool, my CPU never runs hotter than 50deg C, and the case is very well ventilated, usually running around Room temp. If you need any more info, please ask. If necessary, I can run the Mem86 test from a floppy in dos mode, but I have run Memtest 3 times now from Windows and it has come up with an error every time, usually within an hour. Thanks

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 TwinX512-3200XL

Advanced Chipset/Cell Menu

DRAM Timing Settings

Configure Dram timing by SPD: Disabled/User define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 2T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

SDRAM Burst Length: 8

CPU Freq: 200

DRAM Clock: 400 MHz

Memory or Dim Reference voltage: 2.75 Volts

System performance: Standard

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

All other settings should be set to default settings!

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!

The DDR voltage was set to 2.50v by default, I don't know how I never noticed it. Once I raised the voltage to 2.75 I tested for 3 passes with Memtest86 with no errors. Thanks much for the help. Glad that I won't have to RMA my first Corsair product.
