Haswell Overclock Thread

OK, have you tried lower volts? I have a stable 4.4Ghz oc with 1.140V, also not sure if makes a difference but I have **disabled the igpu**, volts went up to 1.152V before disabling but after stayed at 1.140V suggesting more power draw if not disabled.

Hi, just been having a quick read of this thread again as a friend is thinking of going Haswell 4770k and this as far as l can see is the only Post that's mentioned disabling the IGPU, when installing a graphic's card.

Would love to know how many have done this Disabled the IGPU and if so has it made a difference to the overclock Lower Temp's and Voltage Setting's.

Just as you would Disable on broad graphic's on a mobo when installing a graphics card. It make's sense as you should get-

[a] lower CPU temps due to the IGPU being Disabled.

a more stable consistent voltage for the CPU as it's not sharing the voltage with the IGPU and possibly lower voltage setting's.

Would love some input on this whether it does make a difference.

I haven't explictly disabled it, seems to already have been done for me (by the bios perhaps) due to a discrete GPU being present.

So yeah, afaik it would make a difference, however there may be no user action required to achieve this. :)
 
the thermal transfer in the haswell is truely crap. it gets so hot and yet the coolant stays ice cold.

i put a big desk fan pointed into the case and turned it on. just to see what would happen. made 0 difference to the cpu temps, the gpu (water cooled) went down as did the motherboard and plx temps. this thing really really needs to be delidded and im amazed intel are getting away with this shoddiness!

not to be snide, but then you were snide.
thanks for that.

its a great cpu and will be delidded soon. but it still sucks, as did ivy. in this respect.
 
Tbf, it's only in stress testing that they hit very high temps. My 3770k is a pretty bad clocker, 82c max in ibt at 4.5ghz, (1.330 vcore). But in game it's hitting 64c max.

The point is, you can't buy something then whine about it knowing full well from the reviews before it was bought. It reminds me of people that have signed up to things then get ripped off/scammed then complain about it. Thats why I responded to your rant.

Funny how the times have changed. Prescott getting name called to no end for heat issues but when Haswell has it, it's acceptable.

I do not in any way wish to fan any flames here. I can see your points - but whilst purchasers may be aware of problems before purchase - I don't think that this should excuse a poor effort by Intel. There is no way that these cpu should be made with such cheapskate cooling on them. Intel should have done the job properly with soldered heatspreaders on these cpu, or at the very least made sure that the tim they used was good enough and actually was allowed to do its job by having decent contact with the heatspreader.

The other point is that as these cpu are like this then you have no choice but to buy them as is - if you wish to upgrade to the latest tech, and then face the prospect of de lidding to obtain the performance they are capable of without the said restrictions. At the end of the day obviously you buy knowing the caveats, but also think Intel are guilty of cheapsklating on there customers just to make some extra profit. Before someone points it out - I am aware that these cpu cool reasonably effectively if you do not overclock - so yes you should also perhaps expect heat issues if overclocking as it is not guaranteed by Intel.
 
They are guranteed to run stock.
Anything else is a bonus.
4ghz was consider a great OC once.

4.6ghz seems for me to be the sweetspot for my haswell and I am happy with that.
 
There's no point being angry at Intel for selling you a chip that does what it says on the label. We know what the chip is sold as, any overclock on top of that is a free bonus. Intel could have used a better TIM method for running at 5ghz, but the chip isn't sold for that speed. Even if you only get a 4770K that's stable at 4.2GHz, that's still a significant higher performance for free over stock.

You pay your money and take your chances with overclocking anything, and be grateful for any extra you get for free. <shrug>
