Are you SURE youre at 12c ambient? I think youre showing deltas.

Try opening a 3m x 3m window into a 12 square meter room with 2c outside temps ;-)

Yeah i'm talking ambients.

Are you looking for OC results or stable 24/7 operations?

VERY few peopel run their rigs in a 12 square meter (3,46*3,46) with a 3 square meter window room 24/7. And if youre only looking for OC results then 100c is your max temp.

Like a wise man once said: "Whats yo game?"

EDIT: Saw now that you were looking for a voltage-evaluation not temp one (Sorry, I might be drunk). Well VRIN 1.9 or 2.0 seems to be the max going about. Vcore is 1.35-1.4 (24/7) and tops 1.5 (or whatever if youre one of those "I-DONT-CARE-ILL-DO-SMACK-OFF-OF-THIS-DEAD-BADGER-***-MAN-WHERES-MY-SPORK"-kinda people what staple dreml'd titans to 680 pcbs and whatnot.

Yeah it's only for the night while i'm benching.

24/7 is around 1.4v in Normal 23c ambients, max load is 74c in Aida.

I'm willing to push the limits but if i can do that without frying this chip then i'm happy.

Nobody can give you those values. The calculations include the size and weight of your balls mate.

I'm using IBT (Intel Burn Test) as my stressing software :

Multiplier : 42
VCore : 1.19
Uncore multiplier : Stock
Uncore Voltage : Stock

IBT ran for 20 times without issues @ Maximum

Multiplier : 44
Vcore : 1.2
Uncore Multiplier : 40
Uncore Voltage : 1.1

Computer froze before finishing the first pass in IBT, I had to cold reboot it.

Am I doing something wrong here ? Should I put Uncore multi/voltage back to stock and only test Core overclock under IBT ?

I'm running it at stock right now and HWiNFO shows that the CPU is running at Turbo speed (3.8GHz), is it normal ?

1.1v ring probably won't work for 40x uncore multi. Like i said in a thread last night, i went unstable going from 44x@1.24 ring to 40x @1.18 ring, so work with uncore after core and get a few baseline values for it first

So I'm back to start overclocking again. Only overclocking the CPU. Uncore is default and so is the bclk.

Prime95 constantly gives me an BSOD 0x00000124

This is at 1.17 cpu voltage at 4Ghz.

I guess I just need to keep bumping the cpu voltage?

I'd try to stabilize 4ghz first (if you're unstable at 4ghz 1.17vcore, something is probably wrong)

34x uncore 1.15 ring, vrin llc, 1.65-1.7 vrin etc

Which prime?

prime95 27.9 build 1

I'm only overclocking the CPU, so all other voltages are at auto.
And so I thought since I'm overclocking the CPU alone and nothing else at all, only the CPU voltage is to blame?

So I got that BSOD at 1.17. I'm trying 1.18 now. 1.2 will be my limit. If that fails, then I'm gonna sell this CPU and buy me an regular i5-4670 CPU and not overclock it smile.gif

Ring, sa, dio, aio, etc are all part of the CPU, if they're set badly or auto doesn't work, your CPU will be unstable. Usually you're good with a quick set of uncore to like 34x and ring to 1.15v to be stable, and sa/dio/aio on auto, but VRIN is really important to set and adjust as part of overclocking the core. If you're unstable at close to 1.2v at 4ghz, then you probably have a major issue somewhere. It's not super simple to OC haswell blindly, doesn't mean achieving 4ghz is difficult with basic knowledge though
