P95 Failure help needed

post #1 of 8
Thread Starter 
Basically, ram and cpu will pass P95 fine if the ram is at 1333 and its all auto. but if I set timings/xmp profile it fails in CPU-Z. If Im on XMP it will last longer than manually setting the timings. and yes, I am setting them correctly, it runs @ 9-9-9-24-2 @ 1.650v

So for as long as I can remember, running on stock settings I was always stable, but ever since I put this new CPU Cooler on my pc ive been getting P95 errors such as: Hardware Failure detected, rounding greater than .5 expecting less than .4.

I dont think its my cpu, as when I run Small FFT tests I can go for HOURS and not have a single issue, and it remains cool and within the voltages I want it to.

When I run the large fft that only uses 8mb ram, I can run it well also.

Its only when i run the blend thats using 1600mb of memory that I get this error. I am getting that error within 30 seconds of starting P95.


Ive tried manually changing my memory timings, that didn't work. I tried using the XMP profile, when I use the XMP Profile, it will work better, but not fully. I ran it and after about 10 minutes (keep in mind when my memory runs at 1600 via manual timings it doesn't last more than 30 seconds in prime95), but after about 10 minutes, 2 of my cores stopped for that error, but the rest were still running.


Now one thing to note. When i run everything on auto in the bios, I can run P95 forever just fine. But thats not giving me the speedstep to 3.8 and its also running my memory at 1333 not 1600.


I am thinking about RMA'ing this Memory. I believe it could be my fault because I handled the motherboard and took it out of the case without removing the memory from the motherboard first when I was installing this Coolermaster 212+, but ive tried reseating it and it has not worked for me.


If im leaving out any information please do let me know. im just looking for some suggestions to eliminate the different components that could be bad.



Will update my Sig rig if it is not showing the proper hardware, its been a while since ive posted here.


Thanks for the help in advance

How much memory?

Adding more ram taxes the memory controller. It will run at 1333, but not at 1600, the memory controller just can't handle that much throughput.

You have to overclock the memory controller.

Sorry, I'm not familiar with your board, but you should easily be able to find posts about doing what you need to do.

Well it souds like youre having that trouble now.......

Try upping the voltage/lowering the speed. The worst that can happen is....nothing! But you may get a lead to the solution.

I ended up opening up my PC to dust it out, and I just went in and re-seated both sticks after airing out the slots and the issue seems to have gone away for the most part.


I was able to run prime 95 for about 30minutes before I had to do some stuff on the pc requiring me to stop it, but that in itself was an improvement because normally the issue arose within 2-3minutes.

What happened basically after I re seated the memory is that the entire prime 95 was running, but only core 2 stopped, it stopped with the same error. Ive read that it can be an issue with the cpu voltage so based on the assumption that I was also on google chrome, steam, and a few other things that maybe it was just a random error. So right after I saw the error occur (the rest of p95 was still running), I just stopped it and restarted the test instantly, after that restart I was able to run it for 2 hours with no issues with heating or errors.


I know its kind of me rambling but does anyone have a suggestion for why that core 2 failed on the first run after i reseated the memory but the test after that all cores/threads ran solidly for 2 hours?


I feel like reseating pretty much fixed it but it was worth nothing and I do want some suggestions.

What I did to possibly fix this was turn off speedstepping because ive read it can mess with the voltages, another solution may be to manually set my voltage?

Perhaps this will help:

Memory is strange stuff. Some high end overclocking motherboards (and some esoteric overclocking programs) allow one to set a parameter that compensates for the differences (in time) it takes for electrons to flow from the various memory slots to the memory controller (as the traces printed on a motherboard vary in length over this path). That parameter is set in billionths (with a "B") of a second and is used to assure that data traveling on the traces reaches their apointed destinations at exactly the same time .

So reseating memory? How about finger prints on the pins? There are litterally hundreds (nay, thousands?) of things that can go wrong.

Nice work! Just be glad you found the right one!

Well I am def. thankful! I was contemplating RMA'ing the RAM, but now that its working I think ill just stick it out tongue.gif


appreciate the input, thank you
