Haswell Overclock Thread

james_2k · 5 Jul 2013 at 11:57

yeah because lots of people buy the 4770 K version to run at stock. they release the k version JUST for overclocking.

im happy with my chip, very happy. but dont pretend we shouldn't expect a certain level of ability to overclock, especially the 'overclock' version which costs more.

i would be gutted if my chip didnt do 4.2. because thats why i paid the extra for the oc chip.

the oc business is a huge one these days and intel know this.

Absolutely, I buy K chips to OVERCLOCK and expect it to do just that.

And it likely will overclock to 4.2. (it seems they all do as a minimum) but the original complaints were about how difficult it is to get up towards to 5GHz. It's not enough that someone's giving you free cake, you want to complain about the size of the slice?

The problem is that we've been spoilt by Sandy Bridge with it's much better fluxless solder. However if you look at the increase in performance with Haswell on a clock for clock basis, I think you're still getting more at 4.6GHz than a Sandy overclocked to 5.0.

What's the realistic alternative? Stick to Sandy Bridge? Keep sending chips back to Intel or OCUK because they won't get to 5GHz? Risk a substantial amount of money by delidding? Haswell is what it is. You have to work within it's limitations or decide it's not for you and stick with whatever older chip you have.

Thats the other puzzling thing that boggles me. I keep reading BUY BUY RETAIL! and they say £6 cheaper is not worth it for OEM, then one starts reading all the delidding. Fair play and thats up to them but they always portray buy retail for the 3 year warranty and the next, so many are delidding and you've just voided the warranty. Whats wrong with this picture?

I prefer buying retail cause I dont want no crap oem chip which have been test. I take my chance with retail and if I do get a crap chip I most likely delid it after warranty.

The reason to avoid OEM is that are very likely to have been tested already.
The probability of getting a pup is a lot higher.

Not if they're from OcUK.

This is a seriously bad myth, ive seen this propogated on various forums. Over the years ive bought both retail and oem chips. Probably the best cpu ive ever bought was an oem q9550, (3.8ghz on stock volts of 1.200). Sure the warranty is less and you dont get a cooler that youll never need. But tbh, ive never seen or heard of anyone killing a cpu unless they stuck stupid voltage through it or they were extremely unlucky to receive a doa chip.

PCZ · 5 Jul 2013 at 22:46

It most certainly is not a myth.
How many OEM chips get sorted through to find good Haswells.

folks on here who got OEM chips with paste on.
Really open your eyes.

setter · 5 Jul 2013 at 22:51

It's luck of the draw, aka the silicone lottery. I have friends who have bought haswell rigs. Some went oem some went retail. All bought from different retailers, (ocuk included). Theyre quite varied in how they clock, on a few the oem chips are doing better.

james_2k · 5 Jul 2013 at 23:03

my oem one from here didnt have paste on. nor any damage to the ihs from mounting.

1Deep · 5 Jul 2013 at 23:07

Are 4770k overclocking better than 4670k on average?

I've managed to sell my current ivy setup and will be going haswell next Friday

Nice OC on your 4770k btw james 2k.

Westyfield2 · 5 Jul 2013 at 23:07

Is Haswell really *that* bad? One of my machines could do with being replaced, and I don't like the idea of buying old tech (Sandy/Ivy), and I would rather not wait until the next generation.

james_2k · 5 Jul 2013 at 23:13

its not bad at all.

thanks 1deep

That was an error, not normal practice.

OCuK offered to replace them with retail versions.

Impossible to tell, youd need mystic meg to help with that, (if you believe in such stuff lol). The only difference is, the 4770k features hyperthreading, useful in video encoding programs, and a few games. It only really shines in games that utilise hyperthreading when running sli or xfire graphics cards. BF3 and crysis 3 being two of note.

Managed to get the lid off my 4770K and apply some LM pro,
IHS had loads of glue on it, much more than my IVY and it was harder and less rubbery.
Took a lot more effort to get the first cut into the sealant.
The TM was dry and chalky, it looked like and had the consistency of plaster.

It is still a lack lustre clocker but now I can throw volts at it and not worry about the CPU temps.

I can stress test properly now, before the de lid it would hit throttling point at the mere mention of P95

james_2k · 6 Jul 2013 at 23:58

so how much difference in temps did it make?

PCZ · 7 Jul 2013 at 00:59

The difference is huge.
Tests that would hit 100C and throttle instantly will now run for hours on end at 70c

Basically I can run at higher clock speeds with lower temps and I don't have to worry about stability because I can now stress test properly.

Nonsense. I was suckered into believing this from all the tin foil hat wearers but my last 4 cpu's have all been OEM and were as follows-

Q6600 -3.6ghz
I7 920 -4ghz
Sandy bridge-5ghz
Haswell 4770k 4.7 (comfortable,so far 1 day old)

Maybe some companies do this but I bought all the above from OCUK and have had no problems at all. I think I have had amzing luck getting such good clockers everytime but this proves to me OCUK do not sell us the duffers as OEM products.
