I,ve been struggling with this too long. I've played with SA,A/D I/O, DDR frequency, timings and so on without success.
As long as I put that high voltage to cpu the 9c has gone. This cpu is a piece of crap I think. I saw same of them can do 4.7 on as low as 1.28v or something.

To be stable it needs as high as Vccin 2.0v, Vcore 1.5v@4.7GHz and Vring 1.2v@4.0GHz. I think that it’s not worth the risk of cpu killing in order to get 100MHz more. I'm rock solid at 4.6@1.35v.
.
BTW, If it’s not fully stable in x264 bench there is 99% chance that game like BF3 or BF4 suddenly crashed. Nobody like that happen mad.gif right.

Have you tried backing the Ring multi down? What RAM speed/timings are you using?
post #3703 of 19603
Yeah I've tried with x34 and x38 ring multi. RAM is corsair vengeance @1866 9,10,9,27 1.5v but I've set them @1333 9,9,9,24 1.5v during bench.
It didn't help at all.
post #3704 of 19603
Hmmmm....Have you tried increasing the RAM voltage? Like going to .3-.5 above the "rated" voltage? That seemed to help with my G. Skill RAM....

Also, if you're getting a BSOD: what error code is it giving you?
post #3705 of 19603
I say it that way, my system is running perfect and super stable @ 4,6 GHz 1.26v and i have no issues @ all with the board so should i update just to have newest BIOS or is it useless or stupid to update when everything runs that fine?

Average person hits 4.5 at most 4.6ghz.

Personally, I'd say if you have your OC dialed in and stable, then there isn't really a need to update the BIOS. On my board, I had a few stable OC profiles saved, and when I updated the BIOS, my profiles weren't recognized by the new version. Not sure if it would be the same for your board, but it's something to keep in mind.

Thank you, than i will keep my BIOS and be happy :-)
But BIOS updates cant increase the performance of the cpu or? ( i mean markable , not 0.01 % more performance?)

From what I've seen so far, the BIOS/UEFI updates have had no impact on my CPU performance - I've updated mine 3 times now. The only difference that I saw was a change in the format used to save the profiles. That actually pissed me off, I did a bunch of half-delirious late-night OC'ing and got a 4.7ghz stable clock while also OC'ing my RAM to 2400mhz (up from the XMP profile of 2133), and lost the saved profile. Since I had no clue what I changed, I haven't been able to get that OC working again. mad.gifdevil.gif

I left it on 1.9v after reading the Linus guide when i started to O/C. It wasn't till i moved from x49 to x50 that i had to change it. I actually had it at 2.01v at one point near enough stable (just under 8hrs XTU) but if i changed vrin or vcore slightly in either direction it would bsod. Must have just been a fluke managing to run it at that. It's also on the low side for running 5.0 at 1.35v i reckon. Current settings seem fine.

One thing i've progressed with today though is uncore. As mentioned, i could go all the way up to x48 x264 stable but fail XTU, 124 every time. I even screwed up the vring to around 1.4v and still failed. I'm currently at x42 with 1.25vring (i've passed this on my 4.9 O/C, infact i've passed a higher multi than x42 at this voltage) which also failed running 1.3vring. Couldn't for the life of me get it stable. Time to stop and re-think! I decided to drop vring to 1.25v (a known uncore voltage for passing up tp x44 stable) and bump vrin by .025v. I've now run XTU for twice as long as before and fingers crossed when i wake up tomorrow it'll have done 11hrs no problem.

Seems quite logical needing to bump vrin. When i O/C'd core to x50, 2.125vrin was the lowest stable i found. That was with uncore at x34 with 1.15v which probably isn't very taxing. Vrin precedes both vcore and vring in the haswell diagram therefore it makes sense that if i was already on the edge of vrin, increasing vring would need an increase in vrin due to the extra draw.

I'll check this out tomorrow. I'll set uncore to 1.15v which i used for clocking the core, raise uncore multi from x34 and see where it fails. I'll then raise vring keeping vrin at 2.125v and see if i can get that multi stable. If i can't then for me thats 100% confirmed that vrin needs to be raised to accommodate the extra vring.

Hope all of that makes sense, i'm off to bed!
