4670K Clocking

Martini1991 · 26 Jul 2013 at 11:25

At the moment I've just got my 4670K running 4.6GHZ at 1.3v with a 4.4GHZ Uncore.

What's the maximum Vcore to put through it, and what's the max to put through the uncore?
I'd probably be running this until either the socket 1150 refresh or Skylake mainstream, so it has to be 24/7 safe voltage (Well, not deadly voltage)

It's under a custom loop, a thermochill PA120.3, EK Supreme HF.

To get stability it seems to need 1.4v for 4750MHZ but I've backed it down, not sure if that's safe voltage?

Cheers.

Is the CPU modded and what temps you getting?

You dont mention motherboard RAM set up etc???

FML, I missed out a few details

It's the Hero VI.
1600MHZ Patriot RAM (4x4GB)
I'm getting about 70c encoding.

It's not delidded.

I would say your max with that cooling is around 1.35v Vcore, 1.4 Cache.

Is that 1.35v due to to not wanting to damage the chip, or temperature limitation?
I wouldn't mind it running a little toasty.
When I was playing about I did 4.75GHZ at 1.4v and that didn't get too hot encoding ; 78c ish after an hour.

Just degradation mate. 1.4 should be your absolute max.

Martini1991 · 5 Aug 2013 at 16:47

Agh that's fair enough, I might just leave it at 4.6GHZ at 1.3v.
Hopefully get better luck with the refresh (If there is one) in 2014.

Haswell refresh is confirmed yes.

4.6 Haswell is very close to 4.9 Ivy. Try improving Cache and memory for more perf.
