y K8NSNXP-939 is as stable as a squirrel in a bag of nuts.


Recommended Posts

I purchased a Gigabyte K8NSNXP-939 motherboard, Corsair TWINX 1024-3200LLPT and an AMD Athlon64 3500+ CPU about 2 months ago. I have had nothing bout problems with the system (and the company that I purchased it from). The first motherboard failed within a week, so off it went back to Scan Computers; Two weeks later (after a lot of e-mails and phone calls) another MB turned up. Ran it for about two weeks, during this time it was unstable; tried different O/S versions (I use Linux) same problems, lots of Ops!!! at different memory locations. So sent it back. Scan said there was no fault or compatibility issues it was Linux. After a lot's of e-mails and phone calls to Scan stating that it is not my O/S, it is a hardware or a compatibility issue. Their response was it is up to me to find and prove it, nice of them. Next thing it is returned with a new CPU as they had found a fault with the CPU. Put it all together and back to get an unstable system again. :(: After looking at the forums I have set the memory to this:


Dim Voltage to +.2 Volts:

CAS Latency CL=2.0

Row Cycle Time tRC Bios Default

Row Refresh Cyc Time tRFC Bios Default

Ras# to CAS# delay tRCD 3

Row to Row delay Bios Default

Min Ras# Active Time tRAS 6

Row Precharge Time tRP 2

Write Recovery Time Bios Default

Write to Read delay Bios Default

Read to Write Delay Bios Default

Refresh Period tREF Bios Default

Enable 2T Timing Disabled


I have noticed that it is only stable when not in “Dual Channel” mode.

With the DIMMS in slots 1 & 3 prime95 had been running for 2 days.


In slots 1 & 2 fails prime95 straight away.

Beginning a continuous self-test to check your computer.

Please read stress.txt. Hit ^C to end this test.

Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.

FATAL ERROR: Rounding was 0.5, expected less than 0.4

Hardware failure detected, consult stress.txt file.

Torture Test ran 1 minutes - 1 errors, 0 warnings.


In slots 3 & 4 the system will panic on the way up.


but memtest86 runs fine in what ever slots I put the memory in.


Now the rambling is done. Did I purchase the right memory? Could this be a memory / compatibility problem or is it another buggered MB? As the MB is the cheapest of the 3 components what other 939 motherboards work with this memory as I think that Scan will not change it again and I will have to purchase another one. :mad:

I have just been looking at the problems that other people have been having and there are a lot. It looks like either the MB is Cra? or it is incompatible.:(:


Unfortunately I don't have a spare CPU, motherboard or memory, lying around to test each component; so I will have to purchase something first. I am thinking of the motherboard as it is the cheapest thing to buy. I am looking at the following:


Abit AV8 3RD Eye (Socket 939) MB

Asus A8V Rev.2 Deluxe (Socket 939) Wireless Edition MB


MSI K8N Neo2 Platinum (Socket 939) MB or MSI K8N Neo2-54G Platinum Wi-Fi Edition (Socket 939) MB.


Do you know if the Corsair TWINX 1024-3200LLPT memory that I have purchased is compatible with these motherboards? Also do you know anything about them?


Do you also understand why memtest86+ works fine in a “dual channel” setup but nothing else?

I am using v 1.30 of memtest; 48 hours later and not 1 error. I am also using the F6 BIOS. Would you expect to see such a difference between 48 hours of memtest working and under a minute of prime95 failing?

Hi mate,

prime fails in windows or linux when in Dual Channel mode and is OK on both O/S when in single channel mode. It does look like you are getting a lot of questions about this board.

I would make sure that the Bios you have are new enough to support your CPU. If it is then I would try and RMA the CPU and see if that will solve the issue. If you like we can try replacing your modules, but from what you have posted, it sounds like there is some other issue.

Thanks for the help / support so far. I am going to send it all back to Scan on Thursday. I have already had 2 MB's and 2 CPU's, I think it is another MB. If it comes back with them saying it is all OK then I will take you up on the RMA offer. As I am in the UK is it the same procedure and return address ? Although I purchased the memory only 2 months ago can you see from the number if it is old? If so does that make a difference.

Hi RAM Guy,

Just spoke to Scan computers who have said that they will not RMA the memory. Am I stuck now or is there a Corsair contact in the UK that will replace the DIMM's?


A feed up and pissed off guy who would say to any one DON'T USE SCAN COMPUTERS IN THE UK IF YOU WANT ANY FORM OF SERVICE.

Thanks wired, yes I would ask them to read this thread and or if you like you can submit the RMA directly.

To Scan, we replace all RMA's with new modules for the life of the module no matter if you are a reseller or an end user...

Guys I have now spoken to Wesley of Scan who has sorted out the clerical error. Wesley has been helpful in sorting out the problems, so after 2 Faulty CPU's and 2 Faulty Motherboards I have stared from scratch. I am n ow running the Asus A8V Motherboard and guess what!!!!! no problems. I have been running prime95 for 2 days all is OK. So if I was you and your still getting problems try to get your motherboard replaced with a different one.


Thanks RAM Guy and Wired for you help, along with Wesley for being flexible and sorting out the problem from Scan.
