4670k average OC

[Stickmansam]

So my z77 mb died yet again so I am thinking of selling my 3570k since a friend is interested. What is the average OC I should be expecting on a 4670k paired with an H60? I am able to hit about 4.4 with my 3570k @ ~1.2v (Its been a while, I OC'd it then left it alone).

My mb price is pretty much built in regardless since they think I might have bent the pins and that causing the issues. Its impossible for bent pins to have occurred since the mb died like months after I put the CPU into a brand new socket. So costs is mainly from 3570k to 4670k

I believe 4.2-4.3 is the norm unless you get a golden chip like Balla

 

[JimmiG]

Hard to say what the average is, and it wouldn't mean much. Either you get a good chip or you don't. Some top out at 4.2, others do 4.6+ easily. I think the vast majority of chips should do 4.3 - 4.4+ though.

What would be the temps I should be expecting at 4.2-4.3ghz with say ~1.2v on an H60?

High 70's to low-mid 80's Celsius in AVX stress tests, 65C in games.

I hit mid 80s at 4.7 1.18v using a macho rev. a during stress tests

Could be cool as a cucumber, or hot as a furnace.

You enroll in two lotteries with Ivy/Sandy, clock speed potential and IHS distance.

What stress test?

Try Linpack 11 and report back

You meant Ivy/Haswell?

So true.

 

[BallaTheFeared]

Yeah Ivy/Haswell, sorry!

 

[tweakboy]

I would agree about that.

 

[Stickmansam]

Hopefully I get a golden chip like some you guys seem to have

Do you guys think AVX2 and FMA3 will become useful in games because it seems like very few games use AVX since the two years its been out

Yes it will. Grid 2 already uses AVX and I think Rome Total War II might use AVX2.

He's running it at just 1.18V. It doesn't matter whether it's 4.7 GHz or 4.2 GHz. It's the voltage that determines your temp. This is why you want a chip that can achieve high clock speeds at low voltages.

It matters because many people on this forums deliberately don't test with Intel Math Library Linpack because they either have the voltage set too low for the frequency to be stable, or they set the frequency and voltage too high for their cooling solution to keep it under throttle temperature under Intel Math Library Linpack.

nonsense as its not just the voltage that determines temp.

Clockspeed does effect temps along with vcore. Test it and you'll see.

Have you tried Linpack 11? Kind of makes Intel Burn Test look tame. Pretty much the hardest hitting stress test currently available.

If real world use of avx2 is similar many Haswell overclockers are in for a world of hurt.

You could crank up Sandy Bridge pretty high with low voltage runnining Win7 without sp1 which had no avx support. They were marketed on ebay as redline chips all the time.

Yeah I'll be groining in pain when I double the throughput of SB/IB at the same clock speed :awe:

At lower overclocks your statement would be true.

I didnt mean performance as it's the plus side....Insane temps are the problem I was talking about at higher clockspeeds.

Guess it's going to come down how the use is implemented in real word scenarios.

 

[BallaTheFeared]

Well why would I care if my OC was too hot if at stock it was 50%+ faster than what I was getting with an OC?

As an add on question, whats average overclock with no voltage increase?

As an add on question, whats average overclock with no voltage increase?

My 4670k running at stock settings under AVX loads has a vcore of 1.168v's....Same vcore required to run at 4.2GHz using a fixed value.

I run mine at 4.375Ghz using 35x(1.25x strap) @ 1.200v fixed vcore.

MB choice may play a role more in Haswell as voltage control seems to be the biggest hurdle because of the xtra .1v AVX related vcore boost.

Stock cooler overclocking....Most likely little to none dependent on work loads.

 

[JimmiG]

With fixed voltage, I don't get the AVX boost.

With adaptive, it's harder to achieve reasonable temps in AVX stress tests because of the boost, but I still prefer that for 24/7 use. In normal games and applications, and especially when e.g. browsing the web, the voltage/temps are lower. You can always use the "Max Turbo TDP (W)" or similar BIOS option to limit the clock speed under extreme loads like AVX. 170-180W seems to be a good value.
