Still in the process of overclocking my 8350 (Full specs below if needed).

I currently have it manually set to 1.2v, a guide I'm using recommends 1.25v.
I'm not pushing the cpu voltage very far (Still within the 1.36-1.38 mark), how far it enough for stability?

Finally, what kind of detrimental effects can this particular voltage have on either the mobo or CPU?

not enough voltage brings little risks, itll just not boot or BSOD, make sure the motherboard can be reset automatically (if it detects failed settings) or with a clearing of the CMOS battery (for cases you cant get post).

Well it's certainly booting.

While I'm at it, to save making a new thread:
CPU LLC, High or Ultra High to counteract vdroop/vdrop?

At Ultra High I've observed it going way over the mark on the voltage front. (Stock 1.3625v shot right up to the 1.38v mark).
At High it goes slightly under normally, and slightly further under load. (Say 1.375, goes to 1.368).


I'm just trying to figure this out, since at the moment I'm left head scratching at a one core failure in prime, after 20-30 minutes, where the resulting 'error' number was so ridiculously close to the expected that I don't even know if it's worth the hassle.

no one setting will be better, it will depend on your set up. if high works better use high, or if ultra is better do that, it will depend on your tests.. Generally high or ulta high is good (i think thats 50% and 75% with extreme being like 100% maximum droop counter)

this here is still the best guide around

Yup, it's the guide I'm using :F

But I'm getting cocky and moving figures around. I had a feeling 1.25v on the CPU/NB would be causing the mobo to struggle a bit. If it isn't, I'll probably revert back to the settings shown on that page, including Ultra High. (Although, even with the H80i my particular 8350 is the devil for heat. I'll have to see if UH is too much.).

honestly if youre just starting out stick with stock, and change one setting at a time...its hard to figure out where the problems are coming from otherwise
