[SOLVED] Need help with running a stable system on STOCK clocks - Prime95 failing

post #1 of 50
Thread Starter 
EDIT:
Seems to have been my initial guess, a bad RAM stick/module.
Memtest wouldn't pick it up, but p95 and IBT were the ones to help here. The RAM module was the cause, after RMA'ing it, everything works and passes without problems


Hey guys,

I thought to myself to create a new thread, as I feel I'm "spamming" the Ivy bridge OC guide thread.
I will be updating my progress regularly here.

Here's my situation:
In my sig, you'll see what I thought to be a stable OC - it ran p95 for over 19hrs, with no problems.
I then went ahead and gamed on BF3 for over a week, with no problems.
But this week, I launched Borderland 2, and suddenly got a BSOD - which made me go back to the drawing board whilst scratching my head.

I re-ran p95, and it failed, with many voltage increases, each of them failing.
I thus tried to think about the RAM, rather than the CPU, as I've always had the same error in prime (Rounding error), and from what I read, people seem to have declared that it might be RAM related.

I thus went and ran memtest86+ for 3hrs - 1 pass with 8tests complete - all of them passed

So now I thought to myself - screw it, I'll run stock, before even touching another thing in the BIOS.
What I've done is the following:
-Reset to all factory defaults in BIOS
-Changed RAM timings and speed to TESTED CORSAIR speeds: 9-9-9-24-2N @1600MHZ
-Manually put RAM voltage to 1.5v (again tested and used voltage by CORSAIR)

Here's my previous BSOD logs:

Here's the p95 error I've been getting lately - usually the same numbers:

FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.

UPDATE:
Any help will be appreciated.
I'm currently re-running p95, via a custom blend to see if anything strikes out again, if it does, I've been adviced by a fellow OCNET user to take out 2 sticks of RAM and re-test.


UPDATE 2:
I've noticed my +12 rail is lower than expected - could it be PSU related at all?


Thanks in advance for any input!

Currently P95 running on 1 slot of RAM.

11hrs later with only 1 stick of ram - I guess this is stable.
(I'm at stock, but so far I'm trying to make sure my system runs without any problems before OC'ing)

EDIT:
I'm starting to think that it is ram voltage.
The more sticks I put in, the quicker it seems to fail - meaning, my ram voltage is too low?
But how can that be, if that's the advertised, and tested voltage?

Anyone out there..? By the way?

IBT passed on 1 stick of RAM - only 5 tests, but done at max (ive heard that causes BSODs, as it really is extreme)

post #7 of 50
As other's have said, it could certainly be a RAM issue and as you have highlighted in your testing it seems that running only one stick has allowed you to run more stable than your previous attempts. I would however try and run memtest a little longer, the 6-9 hour mark should really show you if there is any problems with them. It'll be a long process but test each of them in memetst first then 2 at the same time, be sure that your ram voltage is not dropping as well.

Good luck.

EDIT:

With one stick installed, make sure motherboard drivers are up to date, including GPU drivers and your windows install is working correctly (run chkdsk). thumb.gif

Hi there!

Thanks for the reply.
Well here's my take on it:
Did 1 stick of ram of prime - custom blend 90% of RAM -> Passed for 11hrs
Did a different 1 stick of ram of prime, same settings -> Passed 4hrs -> then I stopped it

That secondary stick SHOULD have failed after 3hrs - I say that as:
1. It always failed at around the 3hr mark
2. When I had those two sticks in, running together, I had errors in p95

I've thus gone back to putting 16GB's in, thus 4 sticks, and now running IBT, with maximum RAM usage, and on 10 flops.
I'll see how that pans out.

As for drivers:
I have the latest GPU and motherboard drivers installed. I'll check again to be sure.

As for windows installed correctly -> I did think that to myself, especially after googling the hal.dll & ntoskrnl.exe errors.
At the moment, I have a problem with the ASUS AI SUITE II -> Fan controller service would never start up, as in the service.
So I got rid of the asus software, and got rid of its service, to eliminate conflicts (this was done ages ago, and wouldn't explain the BSOD's)

I appreciate the help, I will try to get back, after the 10 Gflops have been completed.
If those pass, I'll run a in-place FFT test via P95 for a few hours.
If that passes too, I'll re-run memtest, overnight, as you suggested (over 6-8hrs)


There is only ONE thing that is changed right now:
-I've unplugged my 2x 1TB HDD's both power and SATA wise.

Could EXT TB HDD's cause these problems too?
I highly highly doubt it, due to the nature of my errors, but would like to be re-assured.

EDIT:
Would have given you rep if I could!

IBT just failed:



I'm starting to think that it is voltage related with the ram...
Any ideas or tips?

I've gone back to 2 sticks and will try to run that now...unless someone has got another suggestion?

Edit:
Ran chkdsk - how can I determine if there were any problems? As it didn't seem like there were, and the result was too quick to catch (did a scheduled one)

EDIT2:
The got a pop-up saying there were no problems on memory via the check - so all good there.

IBT just passed on 2 sticks (2 sticks I've already tested, the 11hr pass and 4hr pass ones):




I'll test the other two now.
If they pass -> HAS to be voltage related. Right?
