Haswell Overclocking Guide [With Statistics] - Page 265

post #2641 of 19539
I got a question. First off, I'm very new to overclocking so I apologize in advance if this question has been answered already...
Any who.. I'm trying to oc my 4770k and I can hit 4.4ghz no problem, stress tested and everything (runs a bit hot when stressing..) but one problem that I keep running into is the vcore voltage. It was a manual overclock, and I have the VID set to manual mode @ 1.250v. However when I run a stress test, it jumps to 1.280v at max load, (Prime95 and IntelBT seem to bring this out the most). I disabled SVID Control and EPU Power Saving Mode because I read it was recommended to disable them. Everything else is basically set to auto/enable. Is there a way to keep the vcore stable and not fluctuate like that?

here are my specs:
4770k w/ Megahalems air cooler
ASUS sabertooth z87
16gb Corsair Vengeance pro RAM @ 1600
850w Corsair psu

Stress tests used: Prime95, IntelBT, Intel tuner, Cinebench

Monitor apps: HWMonitor, RealTemp, CPU-Z

The MSI boards aren't bad, ran this on the mpower max

The reason it is fluctuating is because adaptive is set in the bios instead of manual, or whatever your motherboard calls it.

Nice one! I needed 1.88V to hit 6Ghz, & had to keep it within about 5° of bugging out to even POST there.

Disappointed in the IMC though, my 4770k has a worse IMC than a couple of the 3770k I've had. It can't do 3000mhz on water... sozo.gif

I have it set to manual, not adaptive.

I am wondering is it normal that VSSCA+ and 5.5v is fluctuated when I use XTU?

So as most know my chip sucks mostly because there's no way to keep the temps under control. So I've turned into playing with RAM and have gotten my 43 Multi scoring same as what I had my 4.45 Multi in XTU bench (I could never try higher as my temps would click >100 degrees), shaved off 10seconds from Super PI 32M.. all while running much lower volts (1.225v which is folding stable for x43).

I don't know what I had before for Cinebench but for now it's giving me 9.53 @ 43.

Of course this isn't anything earth-shattering but if you're in a similar position, there are other "options".
