1.397v ok for 4770K 4.4Ghz 24/7 clock?

Not stable..

Plz help me OC this chip lol.

So far @ 4.2Ghz @ 1.28v and 1.15 V ring?

Intel burn test gives average temp of 70c but spikes up to 90c

From reading various threads in the ask 8 Pack sub forum, 1.35v is the max reccomended for 24/7 use on water cooling, personally i wouldnt want to go over 1.300 on air for 24/7 use. Have you not tried a manual oc Boom? You could possibly get the same clockspeed on a lower voltage. The auto programs tend to overvolt a fair bit. Could help lower temps a bit too.
 
That sounds massively, massively high mate.

My 4770K is currently running prime95 torture test @4.4Ghz - the auto overclock voltage on my board for that speed is 1.264v. My cores are sitting somewhere between 62 and 70 degrees. Max so far is 72 degrees. I do have a cpu only liquid cooled custom loop running the now though.
 
Right.. Scratch that. It isn't stable. Temp spikes through the roof :-D

Intel burn test just annihilated my PC.

Manual OC, gives me 90c+ @ 4.2Ghz with 1.28v

Oh dear...

Looks like I'm getting 4790K sooner rather than later lol.

Yeah you're right mate. I just let the board so it's thing as was gaming and stuff around 60c. Just ran Intel burn test and the temps went north of 100c haha.

Not sure why it sets such high volts on the auto OC setting.

Gone to 4.2Ghz @ 1.28v. Passes Intel burn test but still massive temp spikes. Averages 70c but spikes to 90c...

I suspect you might find if you do a manual overclock you should be able to reach 4.4 with much reduced voltage so that temps under control keeping it stable.

The Auto overclock just throws volts at a CPU to make sure it works, rather than fine tune things.
 
Crickey, sounds like you got a very bad un temp wise. Mine in sig hit 94c in p95 when i first got it, 1.267v for 4.5ghz. After flashing to a more recent bios ive had to up vcore to 1.271 so prime/ibt is off the cards for definite. Best to just avoid stress tests that use AVX instructions with theese chips. In games or benches such as asus real bench it will get to 77c with the cpu fans on auto, (k2 and x2 2350 rpm corsair sp's). So now i just set the fans to full speed and don my noise cancelling headphones. Im a bit undecided still on wether to go DC as i could end up with a worse clocking but ultimately all round cooler chip.

It will do 4.4Ghz @ 1.28v for benching 3D Mark 11) etc, but isn't temp stable during Intel burn test etc, have to have fans on Max. (Antec Kuhler 920 push / pull fans)

4.2Ghz @ 1.28v temps are fine in games, but Intel burn test gives spikes of 90c. Does that matter as it's not a normal representation?

Was thinking would stick with this 4770K if could manage 4.4Ghz 24/7, looks like I'm def going with DC if the temps are better. Can give this chip to my boys. They will only use at stock anyway.

Tbh id just avoid using stuff like ibt/p95 etc, though even at 4.2ghz it's still a very powerful cpu. I compared a few benches with my old 3770k. The ib at 4.5 and the hw at 4.2. In the various 3dm benches the hw was on a par with the higher clocked ib, same gtx 670's in sli at the same clocks tested in both setups. Im gonna wait to see a few better reviews of DC, particularly ones that show load temps when oc'd and using a better cooler than the stock one in the hexus article.
 
Like setter mentioned sometimes with haswell, you just can't rely on those torture program's to confirm its stability. As you mention temps will call it short, but that does not necessarily mean it's not stable when running slightly lower temps @ 4.4ghz. More normal workloads :D

For me if you can run, cinebench , 3d mark, super pi and asus real bench ( to name a few ) I'd say your stable on that chip ( being haswell ) at said rated speed. Just not IBT / prime stable. ;)

Sure you can crack 4.5ghz in the next 24hrs .. :D good luck
 
For my 4670K 4.4ghz used the following settings on Gigabyte GA-Z87N ITX :D

V core - 1.25v
Ring core - 1.1v
Chipset voltage - 1.1v

I also changed the system agent / IO analogue/digital voltage slightly, though this was more to do with my ram.

Also I personally find changing the ring frequency to 4ghz helped stability at high clock also. To low at 38/3.8ghz didn't successfully boot.
 
On my board v ring is known as cache or uncore, this ive left at auto as i dont currently have the cache clocked up. Then theres vrin, (gigabyte term) this is the cpu initial input voltage on boot, or vccin on asus. For this im on 1.85

I'd be happy with 4.2 on your 4770k until maxwell. Which isn't far away really.
