Haswell Overclock Thread

Wucked · 5 Jun 2013 at 00:43

Built it tonight, only had time for a quick play but will update later.

4770K + H100i on Gigabyte Z87X-OC & Corsair Dominator PLATINUM, so far just with multiplier 4.4Ghz @ 1.140V prime stable at 65°C. Plan on delidding at some point, but I want to see how far I can push it before I do anything.

Post your results here if you like, I'm interested in what others are getting.

I'll be honest, after all the hoo-hah I was half-expecting a joke thread with a picture of a house on fire or something xD

Wucked · 5 Jun 2013 at 01:06

Understandable, but coming from an i7 920 that wouldn't do much past 3.8Ghz it doesn't seem that bad to me. Perhaps I just have low expectations.

You should do 4.5-4.6ghz imo,seemslike a decent chip

I'll give mine a thrash when I first get my cooler on. But I'm waiting on a bolt-thru kit for my TRUE. 10-15 days from Germany. No-one else seemed to have them in stock. So tomorrow I'll be warming up with the fly-wheel stock cooler.

I'll be interested to see what difference RAM makes. I'll be using 8GB (2x4) G.Skill Eco 1600 8-8-8-8. It doesn't overclock that well to be honest. But it's cool. Does that at <1.35v

I'm all about the cool and quiet for me - but I get interested to see how hot and quick my chips will go.

Update:

4.5Ghz 1.2V 70°C
4.6Ghz 1.272 78°C
4.7Ghz 1.332 90°C

All prime stable. Not willing to try any higher until a delid. I'm going to knock it back down to 4.4 for 24/7 as the volts and temps are nice and low. Not entirely sure about temps either tbh, bios idle temps read 20-30° higher than Core Temp and Real Temp readings. Both Core Temp and Real Temp are perhaps unsurprisingly reading the same in windows.

wow massive jump in temps from 4.5ghz to 4.7ghz and i think you have a good chip there as most seem to do 4.3ghz before thermal barrier kicks in. you will need a very good air cooler with good circulation to keep haswell cool enough, or even better a good custom water loop to push them.

Yeah nasty isn't it. I seem to have finally gotten lucky'ish with the lottery this time though, which is nice. I'm going to delid and test all the frequencies again for comparison sake, then later go custom loop, do them again and hopefully (the gods of oc willing - will sacrifice a donkey or something) see if I can hit 5Ghz.

Whe'ns the delid?

Wucked · 5 Jun 2013 at 20:07

If I have time this week, if not then next week. Going to take it to an engineering workshop at work and use the vice method. Not sure which is safer, but I don't trust myself not to murder it with a blade. Need time to find a suitable donkey h'as well.

dim_pwn · 5 Jun 2013 at 20:46

Whats the point of sick leave if you dont use it for noble causes like 4770k delidding??

I shudder to think if you tested [email protected] using IBT !! :eek:

Hey Wucked, I dont suppose you have had chance to play a few games, see what the max temps are like? Cheers.

arknor · 5 Jun 2013 at 21:11

Do you has well?
You will need a very deep one to provide enough water to keep that sucker cool!

Yes, a few

At 4.4Ghz:

Battlefield 3 MP full 64 player map: 56% Load, 48°C
Supreme Commander 2 SP 4v4 Large Map: 20% Load, 40°C
PlanetSide 2 Busy Area: 30% Load, 43°C

Those three games are ludicrously smooth to play.

I'll update with more games as I get around to playing them, and perhaps later at different overclocks if I have the energy.

Very nice wucked, enjoy your new build, yes it will be like jumping from a escort to a cosworth.

I thought that jumping from a 1055t @ stock > 4670k @ 4ghz

Whilst in the games such as world of tanks that don't multicore the boosts are massive in most other games I got about 10% fps.

Nothing like the jump I did from a amd xp3200+ to a x6 1055t lol

TY

I still have a lot of geeky love for my 920 though, its been a stonking CPU and easily the best value I've owned. It was a close call between haswell and waiting out another gen tbh (if mine did the same clocks as yours I'd have kept it), but the itch finally got the better of me... And I'm now busy trying to find a good home for it, its still got plenty to give.

Vivc, wood and hammer is apparently 100% success rate, going by most places you look for it. A razor on haswell is dangerous someone already killed a 4770k with a razor because it has exposed transistors under the IHS.

People didn't kill their 3770ks even after giving them a good whack 20 times or so it seems pretty flawless.
