i7 4770k 5Ghz OC

[k1ngm4c1u51]

Hi guys

Last night I was able to OC my CPU to 5.0Ghz but! with only 4 cores 4 threads I was trying to hit 5.0Ghz mark with 8 threads but everything above 1.450v hits 90s C or more and OCCT is closing down (safe temps on 85C) I'm fully happy with 4.8Ghz but I wan't more so is this means I need to delid my CPU to gain better temps? Is there any different way to achieve 5.0Ghz with 8 threads?

4.8 Ghz CPUZ - http://valid.canardpc.com/8tassc
4.8 Ghz


5.0 Ghz SuperPi - http://www.superpi.net/Scores/19404/View
5.0 Ghz CPUZ - http://valid.canardpc.com/decjv8
5.0 Ghz -

Max temps: 84, 87, 83, 78

You must have a very good chip there! If I was you I would de-lid it and put some Coollaboratory Liquid Ultra on there. Try a push-pull config on your radiator?

If you really want to push your chip then get a custom water cooling loop.

Could you benchmark it at 5GHz? I'd like to see what it gets

For 4.8Ghz I had Corsair H80i with push pull. Now I have custom WC with push pull too but I need to work on same brand fans, now they are random not same speed unfortunately.

What kind of benches are you interested?

Last nigh I finished close to 5.00 AM and I had no time to do more tests.

What is the cooling solution your using?

What ring voltage did you use for this overclock, what was the Cache speed and what sort of cache volts did you use??

 

[d3rrial]

Wow, my 4770k doesn't overclock at all >_< I can only get 4.2ghz but only with a whopping 1.2Vcore nice OC results, best of luck getting higher OCs!

1.45v ??????

Isn't that a bit too high for Haswell ?

1.45 is asking for trouble on Haswell... I run 4.6GHz at 1.36 and I feel I'm pushing it, when it goes pop, post pics XD

My 3770k started to degrade at 1.35/1.375v earlier in the year.

There's no way I'd put more than 1.3v through Haswell these days.

Hmm, might well knock it down to 4.4GHz @ 1.26v. Maybe 4.2GHz @ 1.18v and run the ram at 2400MHz

 

[tinytomlogan]

Yeah 1.45v is a LOT

I can get 4.9 from mine at 1.26 but Idve never gone over 1.3 - its a good clock but its not a good chip. Id never run this all the time and Id almost call it a n000b clock just smashing loads of volts in it.

Vcore in bios was setup at 1.402 cpuz showing 1.403 and occt reporting as 1.44 and it was only done to test it Im not running it 24/7 Im happy with stable 4.8ghz with 1.250v plus nice temps too and its on 8 threads

Reporting 1.44 was because you had the LLC set too high rather than just setting the volts at whats needed.

What should be LLC for 5.0ghz? Did you get 4.9 at 8 threads or 4 threads only?

Every CPU is different mate. Ive got a selection of 4770K's and all are different.

Theres a massive variation with MOBO's too

Tbh mate I'd just be happy with 4.8GHz and leave it at ttthat. The experience I've had with Haswell at the moment would want to make me pay good money for a chip that did 4.8GHz @ 1.25V stable. I can't even get 4.5GHz with 1.3V stable no matter what I do.
