I was googling somewhere and I found folks complaining about their stock temps during a stress test using the H100.
Is it normal to see stock temps at 60C range during a stress test for a H100?

H100 does no better than the better air coolers so I'm not sure why you would expect anything different

The benchmark above is in the minority. A h100i usually pulls 2-5C better temps than a D14.

I have a D14 and a H100i myself. Using the same fans, I was 4C cooler under load on my 3570k with the h100i

I'd recommend looking at the 380I, very nice looking/feeling block and does the job well too (the more important part). I used to have Raystorm, the 380I does a better job.
Really sounds like you've ran into the same problem as me. I'm 1.32v @ x45 but then trying to get x46 stable in any form became an impossible task, I needed some special sauce that I just couldn't find from any setting. Like you, first you get rid off the 124 by raising the vcore but then 101 becomes the problem and no amount of VCCIN or any other setting "fixed" that. I could be stable for few runs, only to fail on the next. For me it simply behaved exactly the same way between 1.38v - 1.42v with VCCIN up to 2.05v. So I gave up.
Glad to see others confirm this too. Did you happen to run those tests (X264 etc) on the XTU stable vcore and those passed? I assume yes as you're not saying otherwise but just checking..

I did run 20 loops of x264, have that in the screen with XTU & IBT as well here http://www.overclock.net/t/1411077/haswell-overclocking-thread-with-statistics/7350_50#post_21464517

ran Intel burn test got this results any good anyone? I have tried to lower Vcore or offset more but was Unstable push it back to 1.380 +15 offset seems stable on IBT & ya I live in Missouri kinda cold tonight lol


Nice temps for that clock & voltage! I have some nice low voltage for the clock I'm at, but too hot to keep going higher...

I want to try to get it to 4.4Ghz stable and after that maybe go higher if my temps allow it.
But right now it seems impossible to get it running. It always crashes when starting up or at desktop, even if I crank the volts up where I consider it high. So I don't really know what to do now.

The last overclock i tried was:
CPU Ratio: 44
Ring Ratio: 34
DRAM Frequency: 1600Mhz
X.M.P: Enable
DRAM Timing Mode Link
Vdroop: +25%
Vcore: 1.3v
VCCIN: 1.9v
DRAM Voltage 1.5v

I have also tried with even higher, vcore, vccin, ring voltage and both higher and lower ring ratio.
So now I'm clueless on whats causing the crash. I'm getting the BCCode: 124, btw.
Only clock I get stable is the OC genie at 4.0ghz, lol.
I can take some screenshots of my bios settings if that helps.

Drop core multi down to x40
disable xmp
dram timing to auto
vdroop to 85% or higher (or auto depending on board)
vccin to auto
dram voltage to whatever the kit is designed to run at
ram freq. to 1333mhz
vcore to 1.2v
uncore to 1.15v

Boot to windows. If it fails raise vcore by .005v till it does. Once in windows run whatever stress program you want and raise vcore by .005v till stable. If you still can't get it stable, drop vcore back down, raise vccin by .025v then try again.

Did that now. Crashes after a minute or two when running prime95 small FFT.

Put your vccin to auto once see what happens,also i would use x-264 for testing.How about dram timing mode put that to auto

Looks like this is working. Vcore at 1.2v and uncore at 1.15v, boots and still running Prime95. Now what do I do if I want to go higher on the core multi? Just up it with 1 each time and feed it with more vcore if it crashes? Should I increase my ring ratio or is that useless and only necessary at higher clocks?

nvm

hey thank you not sure if this alright but manage to get 4.9ghz 1.380vcore and trying to lower it on offset but crashed so it pushes high of 1.43 or 2 Hwmonitor!
what cpu you running?

Thanks for the input.

Actually my question is about the temps at stock clock (without oc) using any good cooler.

I just found folks reporting core temps hovering at 60C range on Prime95 using the H100 then I'm just curious if these temps are expected for the Haswells at stock clocks.
I'm not sure if their coolers are working as expected and if these temps are fine for any good cooler.

My concern is if I see core temps around 65C at stock clock I would not expect a good room for a much higher oc.
