***Official Intel Haswell Thread***

I wanted to post on here because I just finished my very first build ever. I went with the 4770k and love it, easlily OCd through Bios to 4.1 on a Noctua d-14 cooler. Asus hero Mobo, Haf Cooler master Blue, asus Radeon 7970, WD black 2tb, 16G corsair vengence.

Couple thoughts on this build,
First, I ran the AI suite 3 from asus and the software tied to OC to 4.6 on air and basically locked up my Motherboard, stuck on Bios. The software is terrible.
I got it back down to stock 3.5 and ultimately ended up at a safe 4.1@ 1.20volts and plan on keeping it there.

One change I would make is the Noctua D-14 is freakin huge and doesn't fit well with corsair vengeance ram. I should have just got the H100i CPU cooler, but I know now if there is a next time.

Running stress tests, I never see anything over 115 degrees F and overall I am very satisfied with the performance of this processor.


Also, if I were to do anything different
 
Mine has been on 4.5Ghz @ 1.2 volts for a few days now as I play Assassins Creed III, which is horribly CPU bound (and yet only seems to use two cores)

I should probably stress test it a bit with a multi-core game like Battlefield 3.

Adaptive voltage is on though, as per ASUS recommendations.

If you use BF3, make sure to play a 64 player match on a large map, that's the best way to test your CPU. Campaign is almost all GPU, and smaller maps with less players are a lot less so on the CPU than the massive games.

Going to mess with voltages now and see how low I can go with 4.5 and if I can get 4.6, I doubt I'll succeed, this chip isn't great.

EDIT:

Got 4.6 and I think that's my max unless I get some ridiculous cooling. 4.6 is using 1.34v at the moment. Tried to push it up to 1.37 but the thermals were insane. I throttled almost instantly under AIDA and then bluescreened. Think I need at least 1.38/9 to pull 4.7GHz and a far better cooling solution. I must say though, people are really exaggerating the max safe voltages of this processor. ASUS were saying don't go above 1.275, I can handle 1.275 pretty comfortably for all benches except OCCT with linpack/AVX extensions. I played Cry 3, one of the most CPU intensive games I play and the CPU was barely over 50% utilisation. AIDA put me up to about 85 degrees max. No bluescreen on Cinebench and the temps don't get mega high anyway. Quite surprising when you see that you're nearing a 3GHz 8C/16T Xeon with a 4.6GHz overclock on Haswell.

If temps aren't an issue whats generally regarded as the safe max voltage?

Currently sitting at 5ghz 1.32v peak stress temp of 60c, so hopefully enough room to push higher for some pi runs.

Got into windows at 5.1ghz 1.34v though not tested stability yet.
 
Gonna try a reseat/paste of mine today as the temps are insanely high. Upto 94c inside a few seconds in p95. If still the same im gonna delid, something im a bit scared to do tbh lol.
 
the hammer and vice seems to be the best method,though I havn't tried this

if you are gonna do it make sure you keep the resistors to one side(furthest away from the blade) or stump of wood for vice method

they can break off real easy
 
Dont have ready access to a vice, so knife and take away lid will probably be my chosen method.

Must be a bad mount of the cooler and paste as well, fired up p95 with the system at stock. Temps after a few seconds were. (Vcore at load of 1.248)



This is with the k2 cooler with x2 akasa piranha 120mm fans running at 1900 rpm. Those temps are closer to what i was getting on the old 3770k at 4.5ghz on 1.340v. Dont think ive seen anyone else with an hw running as hot as this at stock.
 
they are just mega hot chips

if your gonna delid take your time,i bottled out atleast 3 or 4 times,aim the blade up and away from cpu pcb,i even cut slightly through the copper ihs so not to damage the pcb

then I used a plastic spreader to cut the rest after I cut just the one corner
 
Yes :)

Worth it for me, my psc kit just arrived so will be testing the imc tonight, then some heavier mhz related clocks tomorrow when my 2666 kit arrives :D

Hopefully settle around 5.3ghz @ ddr2700 cl10/2400 cl7 for benching.
 
£705 for chip, x-oc & ram, rough breakdown values the chip & bundle oc at around £390.

Yes :)

Almost tempted to say you should've gone for an LGA 2011 chip? Although X79 is a bit of a haggard old dog, 6 cores vs 4 with OC is going to get you a lot more than your OC'ing will. Still, truly amazing if you get 5.3GHz.
 
I actually ditched X79 (3820) to move to Z87 after the IB-E benchmarks came back duds.

I have little need for 6 cores atm, so Haswells stronger IPC and IMC appealed to me more then just some extra cores.

Will tide me over until HW-E & DDR4 anyhow.

5.3 depends how well it scales with voltage and obviously temps, hopefully be on the cards if I can get 5.1/5.2 stable for around 1.35v.
 
Fair enough. What sort of stuff are you using the hardware for?

Doubt I'll buy into an extreme series system for a long time, I don't have the money nor do I need it - more GPU power and better cooling is far more important to me haha.
 
I've have the following;

- i7 4770K
- ASUS Z87 PRO
- Corsair H80
- Silverstone FT02 (With air predator fans)

Using AI Suite 3 on 'Extreme' tuning, it overclockers to 4.9ghz.

Seems stable, hasn't crashed through any gaming (BF3) or doing 3D Mark test multiple times.

Ran Prime95 (Small FFT) for 20 mins and temps went to 80 at highest point, thats with case fans at 'High' and H80 on performance mode.

That's a very good result for Haswell.

And yeah BF3 is a good way of determining stability.
