P67A-C45 B3 BIOS 1.10
I5-2500K 3.3Ghz
8GB 1333 [4Gb x 2 Corsair CMX8GX3M2A1600C9]
GTX 560 [Gainward Golden Sample]
Win 7 64 bit
[case CM HAF922]
[650W Corsair]
[2 SATA Hdd + 1 SATA BD-R Writer]

After some weeks of intense use, i collected theese BSODs  :undecided: :undecided: :undecided:

BSOD 08-04-2011 [VLC,viewing an avi file,with bios 1.9]


BSOD 10-04-2011 [during a game i do not remember,with bios 1.9]


BSOD 14-04-2011 [during Crysis Warhead,with bios 1.10]


It's surely not usual. As pieces are all brand new!
CPU temperature does not get over 60? at full use, GPU not over 75? at full and intense 3D use.
I also played all Mafia2 without 1 BSOD  :think:

Memtest86+ 4.20 [ALL FINE, no errors after 1 hour, 1 full pass]
Nvidia drivers [266.66 64 bit]

At first view it seems ram or nvidia drivers, first gets 100% good from test, nvidia drivers are certificated  :undecided: :cry:

What's up?  :bonk:

Have you done a HDD test?  Speaking of, what brand(s) and model(s) do you have?  They should have some sort of diagnostic tool that came with them or you can find them on the manufacturers site.

No! I can't think the problem could be the HDDs  :nono:

Anyway

MAXTOR_STM3320613AS 320GB (the first bootable os hdd)
Hitachi_HDT721010SLA360 1TB (the second, for storage)

They are not new, they are from the other pc and never had a problem (the new pieces are the ones outside brackets [ ] ).

SMART test checks all fine on both hdds.

The three BSODs you show point to a possible memory-related problem.

Have you always had these BSODs since you built the computer?

Tried with just one stick of RAM?

As i confirm by my post, a ram problem is the first clue. But Memtest86+ gave me a perfect check, no errors in 1 pass (about 1 hour of test).

Never. I started with BSOD with the first screenshot (8/4/11). PC was assembled at the end of March, the last week.

Not again. Since the BSOD is totally random, i can't reproduce the error  :bonk: :bonk: :bonk:

I recently changed the bios sata mode from IDE (default) to AHCI, using Windows drivers (which i read could be faulty). I installed today original mobo Intel drivers. Let me see if this could be the problem... i test next days for new bsods (hoping not  :hypocrite:) ...

BSOD with Stop: error code 050 is not enough DRAM V.

Sure?..Ram voltage is full bios responsability  :shocked_anim: i recently upgrade bios from 1.9 to 1.10 thinking the problem was there, but today: BSOD :bonk:

New bios says
- Improved memory compatibility.
- Improved VGA card compatibility.
- Improved USB gaming mouse compatibility.
... maybe i'm not in a hardware problem, but still bios problem... don't know where to point my finger...

Over the span of 3 years, if the BSOD 050 showed up, not in one or two cases, but 'every' time, DRAM V. increase solved the problem. Try just one bump above Auto to start. Then another if needed. If that does not solve the problem, then RAM more compatible should be selected with standard DDR3 1333 SPD profiles. Sandy Bridge native support is 1333.

Your RAM has standard DDR3 SPD profiles for 1333 9 9 9 24 @ 1.50v's (JEDEC #4), & that is what default should set in the BIOS, & it should work without getting BSOD of 050. Could you provide a screenshot of the Memory Tab please? You can try to enable X.M.P. & see if if that helps, but you shouldn't have to do that for it to work right. By that SPD screenshot, your RAM has all the right attributes to run without any problems.

I'll try the AHCI correction first. See if that could be the problem.

At first BSOD (still hoping NOT ;)), i'll investigate for ram settings.

Since the problem is random, it's not easy to catch the real cause  :bonk: :bonk: :bonk:

Your video card is factory OC'd, right? I was researching my new card MSI N580GTX Twin Frozr II and saw a reviewer on NewEgg with the same issue. He had to adjust the voltage on his video card to stop the crashes while playing games at highest settings. Let me try to find that link.

First i tried flashing new bios from 1.A to 1.B:
- Improved memory compatibility.
... they know the problem, i think!  :rolleyes:

Yep. 900Mhz factory OC, from default 822. If you catch the link, i'm here, thanx.

Have you tried increasing the DRAM voltage or are you still expecting the BIOS to do it for you on it's own? Another thing, a single 1 hour 1 pass of memtest is far from enough of a test for RAM. If you don't test as recommend then we are going around in circles and getting no closer to solving your problem. BIOS is only going to set DRAM voltage on auto setting according to what is programmed on SPD chip of RAM module which is 1.5V

From another post by Mike last year:

"...You should still run Memtest. A quick and dirty method is to run test #5 20x and test #7 20x. When running all the tests, you should run them overnight about 8 hours."

Had the similar problems in the past, since updated my BIOS from 1.7 to 1.8.
Ramdom freezes it's all about that.
Well, i flashed back to BIOS 1.7 and that's now all fine, already two months.
