look at his voltage further down in the posts....1.28v @ 4.750????how is that possible
Until I see a cpu id val I don't believe it either cause some asrock x79 boards sensor pickup cpu vcssa voltage instead . Ive seen vals in the 5Ghz club with that bug that happen to be x79 asrock boards tongue.gif edit: just looked at this dudes val looks great but like i said so 5ghz would be 1.35vcore I doubt it .But he might have a goldie malay 3820 batch L202 like my first ( and best 3820 RIP ) this my opinion thumb.gif
Edit apparently its the p67 fatality and pro that is well known for reading cpu vssca voltage for vcore so I stand corrected thumb.gif

Its an older case, you have to stuff cables behind panels, there are no integrated cable paths smile.gif

never tested this clock at this voltage before but quickly tried cinebench and seems to be ok.

You can use extensions and hide all cables behind motherboard tray. But still looks a lot better than before, goodjob smile.gif

HEY... how do you know my VRMS on my other board aren't shot and killed the cpu? Huh? HUH !??! smile.gif Come to think of it, I got BSOD's right after I built this system, with the old motherboard. I traced them to video drivers... but I wonder.....

On the lighter side..

4.3 ghz stable (43x100)
~1.064 vcore @ idle @ ~34-38c
~1.288 vcore @ 100% load @ ~65c average
Ambient temp ~20-21c

My temps are not corrected for ambient.
The hottest core touches 67c, the average is more like 64c.

That's a far cry from my ~84c loaded temps.

-Overwhelmingly positive pressure fan setup
-Changed the rad from exhaust to intake
-cleaned the front intake fans and removed a bunch of metal grilles on the inside of the brackets
-better cable management
-reapplied thermal paste, had a wee bit too much (when I say wee, I mean WAY too much)
-mounted rad with hoses on bottom instead of top like this Rad █____▄ cpu instead of Rad █¯¯\_▄ cpu

Edit: Just managed to lock up, running prime95 with 5GB ram used, and IBT eating up the rest. No crash, no bsod, no minidump and no Event log in windows.
The even log didn't catch the lockup, only the reboot and said the source was "Kernal-Power".

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

Along with some debug info but nothing specific. A lot of 0x00 errors.

Ah well, shes stable in prime95 anyway smile.gif Plus this is on all auto voltages and the lowest LLC.

Edit: Crashed prime95 only after ~20 mins. No bsod, no power off. Just lockup.
Trying a small increase of VTT and a .010 increase offset vcore.

Using OCCT 4.3.2 now, much nicer. And apparently will destroy systems that are stable for 24hours in prime95.
Sorry to hear that you still have problem with your 3820. In your previous post, it also locked up even when at stock frequency. Is that right? If VRMs are too hot, system should throttling CPU frequency, not lock up. So, something else in play here, not temps.

I noticed you're running both P95 & IBT at the same time. Did it locked up when running separately? I wonder whether the memory usage is ~100% when your computer lock up.

This is my 4.6GHz OC. I only ran P95 for one hour. I don't remember the ambient at that time but at least 31C. Offset +0.33 (vcore 1.360V).



Manual vcore 1.376V. Temp a couple degrees higher because higher voltage.
