I'd be looking at setting a manual VRIN for that OC. Somewhere between 1.90v and 2.15v. A few (including myself) were able to rectify BSOD 101 errors due to increasing VRIN, but if you're getting BSOD 124, it's probably due to Vcore or Vring rather than VRIN.

What cooler do you have? Those FPU temps seem a bit high

i have h100i.
well i ment to say that i spreaded it very thin and even. also cleaned both cpu and ihs from those plastic parts

Will chart you soon, thanks.

Didn't FTW get something better with straps? Chart shows a few people who got like.. 46.25ghz or something.

Cache ratio as listed in guide. Also, the input voltage is eventual input voltage, also in guide.

There is no assumption for my CPU. I ran each setting with x264 until it crashed and ran it 5 times and averaged out average time til' bsod. Increased Vrin demonstrably decreased the time til' bsod while going from 1.35 to 1.5v Vcore did nothing for stability. At least for my CPU, it is without a shadow of doubt affected by Vrin at higher voltages. The whole test took me hours.

If you want more specifics: 4.6ghz was the goal. Starting VID was 1.42v. Vrin starts at 1.85v. 1.85 to 1.95 to 2.05 to 2.15 showed obvious increase in stability with no outliers. Each 0.1v increase increased the longest time til' bsod and increased the shortest time til' bsod and the average.ย Prior to the test, I was playing with only super high voltages, 1.45, 1.47, 1.5, 1.512. No dice.

ย 

At this point, multiple people have pointed out stability that was achieved only by higher Vcore and Vrin together.

Likewise i found it impossible to make 47x stable without careful playing with VRIN, and i've 101'd several profiles just by decreasing it

If you just throw big numbers at all of the voltages you end up using too much vcore which then demands that you use even more VRIN etc for stability and it turns into a confusing mess

Can someone help me or are there any guides for gigabyte z87x ud4h? I tried OCing but I don't know what the hell I'm doing smile.gif

It's so much more complicated than 2600k/asrock extreme4 :/

What I did is
-change core clock to 4.5 and vcore (offset) +.00120
-change uncore ratio to 4.5 as well

Gigabyte help tip says keep the uncore ratio at same or higher than core clock.

And the actual vcore when running cinebench is 1.272

That appears to be stable but the temps are unusually high, hitting almost 90c by the end of the cinebench render. In IBT stress test , it goes to 70c for the first 7 seconds, and then goes instantly to 100c+.Why? I freaked out for a moment.

ANYTHING above 4.5 simply doesn't work, windows fails to boot altogether. I did try 1.365 volts with 4.6 and booted but crashed in 3 sec in cinebench. Just impossible.

Screw Gigabyte help. The whole reason why guides exist is because mobo help isn't good enough, else guides wouldn't exist and we'd all just follow Gigabyte help.ย Take a forum guide. My guide or the Gigabyte guide also on OCN. I prefer my method obviously but his is probably more Gigabyte-centric. Or you can cross reference both guides.

ย 

Uncore goes to stock.

ย 

IBT is a super hot stress test, why are you surprised you are hitting 100C @ 1.365v? Eitherย don't run it and run another test or lower voltage/clocks. Don't forget, IBT is hotter than Prime. Serious heat. You can check out my chart of temps, testing stress test temps.

ย 

1. Uncore at stock.

2. Higher voltages require higher input voltages. I'm at 1.42v @ 2.15v input voltage.

3. Uncore is overclocked only after core is done with OCing and testing and is verified stable. Uncore is secondary in performance and importance.

More in-depth reason for my thinking is on the first page.

I recommend overnight x264 for stress test.

I agree that Vrin could be a cause and I disagree that you can tell by bsod codes. If you're doing 1.42v your Vrin might need increasing. In case you don't know, I'm running that EXACT same VID as you right now. And I wasn't stable even when I tried up to 1.515v VID. I found stability at 1.42v with 2.15v input voltage. As I said with the other guy, I did tests that proven a higher input voltage increases stability when Vcore is higher for some people. Average, minimum, and maximum time til' Bsod increased demonstrably per each 0.1v increase in Vrin from 1.85v to 2.15.ย

Guide updated with more emphasis on input voltage.

Guide updated with info on troubleshooting hot temps and having one core cooler than others.

It's so much more complicated than 2600k/asrock extreme4 :/

What I did is
-change core clock to 4.5 and vcore (offset) +.00120
-change uncore ratio to 4.5 as well

Gigabyte help tip says keep the uncore ratio at same or higher than core clock.

And the actual vcore when running cinebench is 1.272

That appears to be stable but the temps are unusually high, hitting almost 90c by the end of the cinebench render. In IBT stress test , it goes to 70c for the first 7 seconds, and then goes instantly to 100c+.Why? I freaked out for a moment.

ANYTHING above 4.5 simply doesn't work, windows fails to boot altogether. I did try 1.365 volts with 4.6 and booted but crashed in 3 sec in cinebench. Just impossible.

4770k
Team Vulcan 2133MHZ 10-12-12-31 1.65V
PSU: Corsair RM750
My CPU Cooler is Corsair H90. Pump is ~1450RPM fan ~840rpm
Room temp is very cold.

Stuff Darkwizzie said. H90 isn't the best cooler and even if you had h100i in push pull or high end air, you can't freely run like 1.3v on i7 very easily.

You should >definately< set uncore to 33x and manual ring voltage to ~1.1 or ~1.15. One variable at a time, >if< you want to clock uncore hard, you do it after you're at the core clock that you want and stable long term

Gigabyte help tip is wrong and i'm surprised that it's still in bios. Are you using f7?

Use manual vcore control, not offset. It will drop voltage on idle and give you 0.02 more under load than you set, you can see this in cpu-z 1.64.0 and in hwinfo
