How well does the 3930K OC?

Hey guys

So on boxing day ill build my new pc, im using a 3930K and a rampage extreme board with custom water loop. I wanted to know how hard it is to hit 5.0ghz? just as a target.

Im not a massively advanced OC'er my first OC was on my i7 920 and I hit 4.4 stable.

Thanks for any advice and insight into what I can expect!

depends on the chip, each one is slightly different

is there a ball park then? do i need to be expecting a special chip to hit 5?

Expect 4.4-4.6ghz

They dont go as high as 5ghz without extreme stuff.

You can be a little more agressive with voltages on SB-E, You should manage 4.8+ for benching, as above you may only see 4.4+ for 24/7 use.

Expect major power usage overclocking that beast

im using a 850 watt psu, 4.5 would be fine since i guess theres no difference between that and 5.0 in use. I dont care about benching just the fastest speed i can use at a stable state

They are quite stable at high clocks but it is a bit of a pointless exercise. For normal use I run my hex core @4ghz and for ocing/benching up to 5ghz. For every day use you don't have to go much above 4ghz.

You should have no problem getting to 4.4 - 4.5ghz for 24/7 use and a bit more for benching etc.

It is chip lottery,
as others have said 24/7 a 4.4 - 4.6 should be what your looking at.

ok cool thanks, is that with temps at around 70's under 100% load?

Cracking m8, waiting to see how well Haswell performs then l might upgrade, my i7 920:4.3 still does the job.

This is right.

5ghz for a 3930k takes a but load of cooling or a special chip
