For me I didn't have to jump too far to get to 4.8, I believe I had 1.3v at 4.8, but the jump from 4.8 to 5.0 was massive. 1.45v
Yeah i just passed a 24hr prime 95 custom blend @ 4.7 1.415. And i've been trying to get 4.8 now and within a few tests into the blend from 1.45+ all the way up to 1.490 i have had whea errors. I have it at 4.8 1.505v in bios atm. My temps are absolutely fine, honestly my temps barely jumped 3-4c from 1.415 to 1.505v.
Will have to see if i get any whea errors in the first little bit here. Haven't had any workers fail or anything with previous tests. Just whea errors. I'm really tempted at this point to buy another 3770k. It seems like even the average run of the mill chip people get these days can get 4.8 without the voltage that i am pumping into mine.
I'm not sure what to make of this. Do most IB's experience a clock where its a massive jump in voltage? Or could this be a memory issue.
Scratch that just got a whea error after the first pass of workers. Bumped it to 1.515 temps still in check too. Roughly 59-63c across all cores. Pretty nuts seeing 1.51+ v being put into it right now. But the cooling is handling like a breeze lol. If i start notcing any degradation (ie instability making me use more and more voltage), then i will lower the clock. Rules are meant to be broken overclocking. Hell i was running an i5 2500k @ 5GHz on a H100 with like 1.49v going into it. Had it running like that for months. Eventually i realized my computer turned into a space heater so i lowered it to 4.8 at 1.38v lol
Edit again: 4.8 at 1.515v whea error., im pulling my hair out at this point. Going to try and raise my cpu pll some. It was at 1.55 from 1.8. Setting it at 1.9 and will lower it from there to see if it helps get things stable. Also lowered voltage a bit, no point on going up still at this point. Right now i'm 9 tests in and no whea error yet. If i pass the first set of workers on this voltage, and an increased CPU PLL voltage ill be happy. Very odd tho, cause i'm fairly sure i have experimented with this at 1.8 cpu pll before and produced a whea error. Who would of thought bumping it from 1.8 to 1.9 would show signs of stability
Edit: Looks like i may be making progress now. Apparently bumping my PLL voltage up to 1.9 allowed me to lower my voltage down to 1.470 and is also letting me pass prime 95 blend tests. Will see what happens. But it appears that my pll voltage was or is the culprit, nothing for sure yet. And if that's the case i guess my chip isn't a total waste. Was a massive pos if i actually needed 1.520v+ for 4.8
Edit : Yeah it looks like the pll voltage had a lot to do with it i just ran back to back tests with IBT (cause i can produce a whea error faster with it) and when i have it set at say 1.55 ill whea error, if i bump it to 1.85v i dontEdited by EnthusiastG4m3r - 7/12/13 at 1:10pm
