Hmmmm, scrolls to the top of the page....... ohh yeah

***The Official 8HR Stability 5820k/5930k/5960X Overclocking Thread***

Its just the way us old school used to validate overclocks. If it cant last a long stress period then its liable to fall over any time.

you shouldn't worry, you have a good chip there.
Just leave it running when you go bed.

I know it is lol I used to do it. It is just a waste of time, a cpu will fall over regardless at some point. If it can handle 3-4 hours I am sure it will hand 8.

Well, we were all required to run Aida64 for 8hrs min to 'qualify' on this thread...

I know, I did say I was going to do it when I had free time

I think I may have a winner. I built it this morning and I seem stable on 4.4 @ 1.12 volts! WTF.

What batch is your cpu ?
Mine is at 1.12 also and the imc is able to do 3000+ easy (strong IMC from testing so far)

Currently testing while at work so hopefully it will pass and then the clocking can begin, really want above 4.6 stable

I think I'm getting quite high temps and I'm not sure why.

Currently testing my broads OC presents of 4.2ghz, which applies v1.225 vcore under load. However my temps are in the low 70's with custom water running Realbench!

Brand new Suprenacy Evo, with a EK360 rad and a D5 pump (which replaced my 8 year old D5 just to be safe). The waterblock mountings are nicely tight and I'm using the inserts recommended rather then the pre-installed ones.

Do you think i should reseat the block ? also is it normal to get a water jet like nose from the block (you have to put your ear to it allmost) never had such behaviour from my old blocks (DD RBX, Swiftech Storm & Aprogree GTX, XSPC Rasa and now this one).

I would reseat the block to be safe. Do you have your GPUs on the same loop?

Personal I find watercooling a bit redundant for cooling CPU's now days. You hit a voltage limit long before heat limits on model air cooled CPU's.

I don't cool the GPU atm, but i tend to but didn't this time due to a combination of buying a non reference card with no FC waterblock (in the UK anyway) and non standard motherboard slot placement so gpu only block with a bridge was not an option anyway.

I might adjust the fan placements wait a little while before reseating as the block build is less than a week old and the GELID GC-Extreme probably needs a little more time to cure. Pretty happy with the performance at 4ghz so it will be more about the noise. Still would love to see how far the cpu will go

Ill ask on the watercooling forum about the block "noise"

You may have air in the block.

I built mine on saturday and the temps volts are crazy low compared to my 4790k.

I am on a Noctua D14 air cooler in a silent case so airflow is not the best and even when i am pushing 1.32 volts my max temp on realbench is around 60c (Give or take 3c) so your loop should be hitting lower temps.

At 4.4 @ 1.11 volts my max temps is about 42c on realbench just to get you a marker.

Just started an 8 hour run on Aida64 (cpu,fpu,cache, and memory selected) at 4.7Ghz 1.35v

Already passed realbench max memory (32gb) 4 hour test while running P95 in parallel.

ketma · 30 Apr 2015 at 21:24

Cool, get a screen shot posted if you pass the test.

I thought Prime95 was bad for the Haswell-E chips?

ketma · 1 May 2015 at 19:17

Its not recommended as the AVX instructions in the latest version of Prime draw more current and heat the cpu unnecessarily due to the load.

I am running the Non-AVX version

InTrigger · 6 May 2015 at 21:44

Did the tests a while back, haven't been able to find the time to post the screenshots

1) 4.7ghz Aida over 8 hours stable CPU and memory (in the club right?!) 1.35v low 60s max core temp

2) 4.7ghz CPU,FPU,cache,memoRY failed after about 7.5 hours max temp late 60s I think, same voltage

3) same test this time uncore Overclocked to 4ghz (1.15v cache voltage), passed CPU,mem 8hoirs

Will post screenshots to corroborate the claims Asap!

4.5Ghz @1.2v

Trying realbench now.

Bit misleading title. . .

That's not a 4.5Ghz run.

That's 4050Mhz (100x40.5)????

Clearly not 4.5Ghz LOL

Yeh it was 4.5Ghz, core temp's clock speed seems to be all over the place compared to cpu-z.

Had to up the volts a bit, failed real bench after a few hours.

Got yourself a good chip if it can do 4.5 at that voltage.

Cheers Combat, what volts you need for 4.5 ?

Just put the uncore up to 4.5 1.3v, booted fine in to windows, just running aida64 now.

Probs a waste on me as I have not got a clue with this overclocking
