How to overclock Haswell?

Makhaira · 6 Sep 2013 at 19:00

I've read through the Beginners overclocking guide, and it seems to cover most of the information that I already know from 775 overclocking around voltage, multipliers, FSB's.

What has me totally stumped is the whole shift to BLCK, offset voltages, and all the new aspects that have come in with the newer chips. Could someone please point me at a guide for this sort of thing?

Thanks!

take time to read through it,it will give you a good understanding of what each voltage does/controls

That's perfect, it's even a Gigabyte Z87 board I'm getting! (HD3).

Cheers wazza.

Never mind, the guide is there, there's a bug with their forums. See page 124 of that thread for anyone finding this!

Ok, so I've found that guide massively helpful, especially the templates at the end for understanding the key factors to tweak for basic overclocks.

What I didn't realise though is the effect of so called "turbo".

Take an i5 4670k. 3.4Ghz clock frequency. 3.8Ghz turbo. As I understand it now, the chip will automatically boost to 3.8Ghz if put under load? Therefore if I clocked to e.g. 4.4Ghz, I'm not actually adding a 1Ghz overclock at all, I'm adding a 600Mhz overclock since it would have reached 3.8Ghz on stock settings?

Apologies for all the questions, I had no qualms about overclocking on 775, but I feel like all I ever knew is totally redundant with the new chips now! That's before I start considering VIN, Vring, Uncore etc!

I'm in the same boat, i'm attempting to overlock my 4770k for the first time coming from a first gen i7 and it's so different. I can move my mouse in the bios?! It's the future!!!

However, I upped my BLK to 115 giving a clock of 4050MHz but In Prime i'm at 80c, and this is with a h100i. Have I just got a crap chip or am I doing it wrong?
