I didn't think it would be too high. I can retest with 1.8 VRIN.

For right now, Darkwizzie, could you add my result to the list? I'll get it changed later when I have a better stress test result. Going to test with 1.8 VRIN in about 5 minutes.

Username: Shanenanigans
CPU Model: 4670k
Core Multiplier: 45x
CPU VID: 1.255
Vcore: 1.272v
Input Voltage: 1.9v
Uncore Multiplier: 35x
Uncore Voltage: 1.15v
Cooling Solution: Cooler Master Hyper 212X
Stability Test: IBT 10 runs - High
Batch Number: 314
Ram Speed: XMP 1600 - 9-9-9-27-1T

Notes :

Vcore is 1.284v when stressing with AVX, ie IBT. Full batch is L314B297. I've looked on the internet for this particular batch and I couldn't find results. And it looks like the thermal threshold for the Hyper 212X is *surprise surprise* 1.284v. Temps hit about 93-94C while IBT stressing.

What gflops are you getting in IBT?

And chart results with a final oc, after you're done tuning wink.gif

Getting about 115 gflops in IBT. Rebooted to test with 1.8v input. Crashed after a few minutes with 101. Raised vid to 1.26V and input to 1.82v. Going to test with x264 now.

Well yeah lol. Thing is, I know a 101 is vcore based. But I felt the 1.8v input was a little low, even with one step before max LLC.

Well it took about ten minutes to crash at that setting. I think it has to do with the vcore dropping at random times because it seems to be fine at 1.284v in hwinfo.

Not necessarily, clock watch dog is usually 101 (VRin).

1.800V VRin is usually the default value, with the power savings turned off.

That's interesting. Lemme increase the VRIN a bit more and see.

Bollocks. 101 isn't restricted to vrin.

I can't get my head around the amount of random adjusting/OC'ing going on in here at the moment. Some of you may be better rolling a dice and hoping for the best!
post #5230 of 19580
I'm rolling three right now. Still no dice. And no pun intended.
