Possible to RMA 1 stick in a dual channel set?


Recommended Posts

I'm building my sister a new computer for Christmas, and I ordered her a 2x512 kit of PC3200 Value Select. I temporarily borrowed one stick of it for myself while waiting on my own personal ram to arrive, and put the other stick in her computer to set it up. I got pfn_list_corrupt blue screens during both installation and normal use, and research led me to believe that the memory could be at fault. I ran Memtest86 for ~12 hours on that stick, and it returned over 4.5 million errors. I am getting ready to run memtest on the other stick just to make sure the problem doesn't lie elsewhere in the system. If it turns out that only one stick is defective, is it possible to exchange just that one? She'll be fine with 512 megs for now, but obviously the system won't do her a whole lot of good with no memory at all.


The relevant specs are as follows:

MSI K8N Neo Platinum mobo

Athalon64 3000+ retail w/ stock hsf

Corsair ValueSelect PC3200 2x512 kit (VS1GBKIT400)


If any other information or more specific testing is needed, please let me know.

Please make sure you have the latest BIOS installed in your MB and that you have the modules installed on slot 1 & 3; load optimized/optimal default settings, and try the following BIOS settings;

Cell Menu or Advanced Chipset/DRAM Timing:

Memclock Mode: Manual (400)

Bank Interleaving: 4/Enabled

Burst Length: 4

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Active to Precharge Delay (tRAS): 8T

SDRAM Row Precharge (tRP): 3T

Frequency Voltage Control:

Spread Spectrum: Enabled

CPU FSB Clock: 200

DDR Voltage: 2.7/2.75 Volts

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!

Thanks for the quick reply. Memtest is running on the second stick right now. During Test #5, it racked up 216311 errors. I hadn't changed the bios settings, so I'll reboot and do that now. Do you have any suggestions on what I might check next?




UPDATE: I changed the bios settings you recommended, and the results were pretty similar... 211714 errors this time, but they all came at the same point (the end of test 5).
