TWIN2X4096-8500C5D, 1 stick seems to be faulty


Recommended Posts



I have read many posts in this forum regarding TWIN2X4096-8500C5D issues and I'm still not sure what to do, other than to try to tell you guys my "story".


I bought my TWIN2X4096-8500C5D 8 months ago at Datorbutiken.com and around 3 months later BSOD's started to pop up now and then, didn't think more of it at that time, but 2 months ago or so it started to happen all the time, so I put the two memory sticks in different banks, together and alone 'cause the majority of the BSOD's referred to memory problems. It turned out that one of them sticks was much more stable than the other, even though that stick can "generate" BSOD's as well, but that doesn't happen very often.


I have also tried four Twin MOS PC2-5300 / DDR2-667 sticks and they work like a charm.


I have run both Corsair sticks in Memtest86+ V2.01 (21/02/2008) separately several times and each time there are errors.

On the four Twin MOS sticks Memtest86+ didn't find any errors.

I don't know if there's a big difference between Memtest86+ V2.01 and V4.00, but V2.01 was the one I had available.

And I haven't changed any settings in Memtest86+.


I'm not an expert when it comes to overclock etc. nor changing RAM timings etc.



Attached pictures of; BIOS, Memtest86+ results etc...

Thank you for the reply!


The changing of memory voltage didn't help, am still getting those PAGE_FAULT_IN_NONPAGED_AREA, PFN_LIST_CORRUPT, MEMORY_MANAGMENT, SYSTEM_SERVICE_EXCEPTION errors, and Memtest86+ is still finding errors... :brick:


I tried changing the NB voltage, to no avail.

On Vista I can get into Safe Mode and it seems stable, but on Win 7 i get a dark screen, a BSOD for a half sec or this...




And on this system;


AMD Athlon 64 X2 6000+, 3.1GHz

Abit KN9S

Gainward GeForce 7300GT 256MB DDR3

Gembird 450W


I get many errors as well in Memtest86+.




Is it possible for RAM memory to get damaged due to under voltage, and I assume the memory sticks have been tested without errors before shipping out, so how come the memory produces errors for the end-user? I know we all have different PC Specs but that can't be the main reason...



Thanks in advance!
