Bad Memory VS1GBKIT400


Recommended Posts

I purchased a Corsair VS1GBKIT400 kit from Monarch PC a few weeks ago for an upgrade to a new Nforce4 Motherboard. While my Motherboard is still on order I have been using the two sticks in my Abit KR7A (VIA KT266A chipset) Motherboard. So they are both running as DDR266 for now. My Processor is a Athlon XP 2400+

 

My system started to crash over the weekend and so I downloaded the Memtest86+ and started running it this morning. It was still running when I left for work and it had listed over 56000 errors. I looked at the screen while the testes were running and the errors all seem to be between 760MB and 800MB. I would guess that this makes the 2nd DIMM bad.

 

Please let me know what my next step should be. I would like to be sure that both my DIMMS are in good working order before my new Motherboard and CPU come next week.

 

Thanks

Came home and after letting Memtest86+ run for 10 hours had over 1,000,000 errors. I checked the bios revision and it’s the newest for the KR7A, CX, and so I took out the 1st DIMM, set all the BIOS setting you provided, and ran Memtest86+ again. After 10 minutes I had over 250,000 errors. I guess that makes that DIMM bad.

 

I then took out the bad DIMM and put in the one that I think works and ran Memtest86+ for another 10 minutes, no errors.

 

Finally just to test the slots I tested the good and bad DIMMs together again but swapping the slots. This time all the errors happened between 250MB and 300MB.

 

So it looks like I have one bad DIMM and one good one. What is the next step to get the bad DIMM replaced?

 

BTW Thanks for all your help
