It's just talking about a failed overclock. Was this BSOD or just an error on post ?

If BSOD you can catch the error code which will look like 0X000000101 or 0X000000124 etc. you can google the code and it might give you an idea on what to do. For example the 101 code is usually not enough vcore, and 124 is an uncore problem that raising the VTT will usually fix.

If on Post and no error code you can always trial and error it out since you have some headroom on temps. Raise the vcore a bit and see if its a go. If not back it back down and raise the IMC/VTT.

Quick question on voltage, cpuz says its about 1.25ish...it never gets close to 1.35 vcore that I set in the bios.

That would be the vdrop or vdroop that they talk about sometimes.. Try enabling load line calibration in the bios. It may help! Mine is just about that bad..

I see about a .05v drop from the bios to under full load. Its better the smaller it is. but in your case it may be best to enable LLC

Okay, I thought I had read that somewhere, but I figured it couldn't hurt to ask. And sorry for the poor explanation, I was posting from my phone. You got what I meant anyway though, haha.

It was an error after post, but it wasn't a bsod. It was black with white/grey letters, and just one simple sentence, unlike a bsod. I am currently running IBT at 188x21, same vtt and vcore, but I upped the dram volts to 1.52 just to see if it makes a difference, since my ram is oc'd a bit now. If it fails, I'll try upping vcore.

Just to kinda eliminate errors i would download memtest86 and run it for about 45 minutes and let it test your ram at its current speeds/timings/voltages to see if that could be the problem. its good to do overclocking one component at a time.

Sounds like a memory error. I'm not sure how far I'd push that ram on volts. Generally I'm not brave enough to go more than .04v over spec but all my RAM is 1.65v too so I just don't know.

Yep as dembo said that is vdroop. Actually difference between what the setting is in BIOS and idle voltage in CPU-Z is Vdrop. Difference between idle and load is Vdroop. It is not a bad thing.

Yeah, I know, I thought about that after I started IBT...I'm getting a bit ahead of myself here, lol...

Well now cpuz is showing 1.297 at max load for vcore, so I'm not sure what happened there (to make it go higher). Anyway, I successfully completed five runs of IBT at 188x21 (3962mhz) with the dram volts at 1.52.

Thats great to hear.. I'm trying to find somewhere mine can stay at without getting to hot until i can buy water cooling..

Goal was to get the maximum overclock while undervolted so that the power consumption of the cpu never exceed 85w during IBT. It only peaks 70w during prime95.

I assume you're talking about your cpu heat? I'd think with the a70 you wouldn't have any problems. I peaked at 70c through five runs of IBT @3.9ghz and my vtt was 1.3 and vcore 1.35.
