Well from what you say, the system seems more stable.

Perhaps it just needed the settings in the BIOS optimized and reset the timings correctly,
time will tell, and they did pass memtest...so hopefully.

The only way to be sure your free of crashes is to test the system and use it normally
as it seems more stable at this point, then if it performs without crashing, then
I would test with latest video drivers.

I would advise creating a restore point now, may save you a bit of time if things go South

Good luck.

cheers

Well i have several mates with beefy systems like this using 320.49 drivers zero crashes so think i will give them a go.

After so much bsods i am nervous loading up Borderlands 2 now.

Still no bsod tonight, been just over an hour so far.....the main thing i guess if the desktop has no bsods then the games should run very stable.(unless gfx driver installation has been messed up)

No worries, glad to help. Looks like your RAM is compatible after all and the settings were just messed up.

Well that is good news I'm on the Clipper as we speak

Once you feel everything is ok, then can you please mark the thread solved.

cheers

Was all going well until i got bsod browsing net today, please look at attached file.

Think it could be because i reinstalled with the non default settings in bios so messed up some installation files?

Nah that was 4 days or so ago but i had the issues still after the reinstall.(until i found out to change to optimized settings)

That was first bsod in 9h or so useage....so seems to be something minor, i heard 0x50 bug check code relates to a voltage setting too when using 16gb of ram.

Any ideas what the bsod was caused by? it says was caused by cng.sys in whocrashed app.

I will look through your logs momentarily, it just sounded like you had reinstalled again

A Bugcheck 0x50 relates to a PAGE_FAULT_IN_NONPAGED_AREA whereby the
requested data is not found in memory.

But your on the correct train of thought as error code for BSOD overclocking is this:

0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or
adjust QPI/VTT, or lower uncore if you're higher than 2x

This is a method used to fine tune your voltage to correct settings:
(Courtesy of ESSENBE)

*THIS IS FOR SANDY BRIDGE / IVY BRIDGE ONLY*

1. Set ratio to 43 and tune voltage to 1.20 manual
2. Stress with Prime95 for 10 minutes
3a. If pass, bump ratio by 1
3b. If fail, increase voltage by a notch and re-test or lower ratio
4. If passed 15 minutes and happy with overclock, stress-test for 12 hours for stable confidence
5. If passed 15 minutes and unhappy with overclock, repeat steps 2 to 5
6a. If fail 12 hour Prime95 (Worker stopped, BSOD or any error), increase voltage by a notch and re-test

I will post any new findings.

Cheers

I think it may be a corrupted windows file....although if i did install one more time at least i know now stuff should be 100% fine as i be installing with optimized settings.I try some games now since before i do any reinstalls though to make sure they work fine unless there's a fix for it.
