thanks I wanted to know if i should try it, however its always worked at stock cpu speeds and auto voltages...

ill try anyway... maybe the IMC is failing.

CRASH BSOD 101. Because I dont have extra Ddr3 ram kicking around should I bother even swapping around my 8 sticks to see if they have anything to do with it?
So.... psu, mb, cpu. My money is on cpu. Current system calculated to draw 800+ watts in overclocked form (not counting overclock power req. of video card), However stock system should only be needing ~650watts.... at stock speeds. PSU is Corsair HX750, 8 months old.
at stock settings i did offset voltage +0.08.. results in
~1.112v idle ~35c
~1.320v load ~65c using ~125-130w (reported by coretemp)
This ive confirmed stabled for 3 hours prime95 w/ 90% ram being used, and running IBT at maximum at the same time.

Try removing 4 sticks. It could be that one of them is defective. I know Linus @ NCIX had a similar problem where one of his sticks was bad and it took a while to determine which one is was. ohno-smiley02.gif

Also don't run P95 and IBT at the same time. Wait for one to finish then start the other.

Have you enabled the extra options in prime95? The reason folding gets you hotter is because it stresses the cpu and gpu at the same time, hence I asked if you ran FurMark and prime95 at the same time, this will fully stress your system.
As we speak, I just had the system pass 3 hours of prime95 and IBT at the same time. Loaded up furmark and prime again, and she straight up shut down within 5 minutes. I attribute this not to cpu failure but to psu failure as well.
Seems I have multiple issues going on.
No but torturing your system isn't going to ensure reliability. Mine has been stable for nearly a year. Stressing the hell out of it won't help me in anyway. It is a gaming rig, media center streaming and encoding 1080p on the fly plus normal day to day activities. I rarely use more than 8gb but 6gb is pretty standard. The folding with only cpu still produced hotter temps than prime95 granted that was 6 or so months ago since the last time. I just see no reason to do it as it isn't productive. As I said. I have had plenty of prime 95 runs in the beginning seem stable and then go and play minecraft while streaming a hd video and it crash. Adjust my vcore and then it was fine. I just didn't find it to be practical unless all you use your pc for is forums/internet or bragging rights.

I somewhat agree, however when im encoding from premier or something like that, I put the system into full stress mode. I cannot afford to have corrupted data so I need to know the system wont crash or produce a random error and corrupt 300,000 family photos. Ive actually had this happen, not with 300,000 but had quit a bit go on me because of a faulty ram stick.

Its just weird that im getting 0x00000101 errors, even at stock speeds...

Update.

Removed 4 ram sticks, BSOD at windows login screen.
Removed 2 more, loaded windows this time, Bsod after 3 minutes of prime95+furmark
Bsod just sitting in windows.


When changing the ram sticks I noticed the Dual Intelligent Processor III heat sink (DIGI power controller) was EXTREMELY WARM. Like burn your fingers warm.


Also upping VCCSA to offset +0.1 and .15 does nothing.

Stability only achieved with minimum +0.09 offset voltage to stock clock speed.

Sounds like either a faulty board or CPU. Before you do anything else, take out your CPU, and check the socket. Make sure there are no bent pins.

While you've got the chip out check on the back of the cpu for discolouration on the gold pads.......

Ok with 6 of 8 sticks out, I loaded up an OC profile for 4.375ghz 125x35, 1.44v idle (1.42 in bios). Im posting this from windows. Havent stressed it yet.

Funny thing is my Macbook (my wifes macbook) is acting up, I cant get on the forums on it. Even my phone is giving me issues. This computer is now the most operational in my house ... **** smile.gif


Anyway, 4.375ghz is loaded and working, can someone else with an X79 Asus board of see if the DIGI power headsink at the top center of the board is hot to touch even at idle??? I cant keep my hand on it for more than 3 seconds, Id say its around 75-80 degrees at least.

Ill post back with stress results.

It should only be hot when highly overclocked. At idle the board should shutdown x number of phases to reduce consumption. Yours sounds like it is having issues. Check your digi power settings in bios? Did you tell it to run full blast, raise the sampling rates, etc?

Yes when I was over clocking, had extreme LLC, phase to 350hz, etc etc.

But back to stock at all stock settings, everything auto.

Ill let it idle for a while and check the Digi heat sink.
