Yeah it was time consuming and thank you for all the help.

 

[GoogalyMoogaly]

OK, found a 4770K for £240, worth a gamble?

 

[Dave1240]

Have you tried those settings I linked?.

 

[GoogalyMoogaly]

pretty much.
4.5GHz with 1.25v isn't even stable enough to boot into the BIOS, I can't see changing the LLC up a notch (or 2) changing that.

 

[Dave1240]

I will try it on mine, looks like we both have crappy clockers ha ha.

 

[GoogalyMoogaly]

let me know how you get on!

 

[Dave1240]

Take into consideration this is my first Intel build.

4.4ghz
CPU vcore 1.277
Dropped uncore to 32
Disabled the power saving c1 c3
I have set that setting to extreme vdroop or something

Managing to get into windows and running aida64 stability test now.

 

[Dave1240]

Temperatures are 57 - 60

Be careful if it's used, it maybe someones returned cpu after testing themselves looking for a good one.

I believe it's being sold as new, just on offer. Can't link to it obviously as it's a competitor.

Can't wait to get this board.

"Support PCB ver 1.0/1.1"

So is "PCB version 1.1" the Z87 C2 stepping??

I cant see a new revision listed on the Gigabyte site.

As for the two BIOS above I notice that F6 has a newer Intel microcode (9H) than X02 (7H)

I only managed to be stable for 15min on aida64. I was wondering if i could try for 4.4ghz with increasing the voltage past 1.25v?.

My temps at 4.2ghz with 1.25v is only 56-57 maximium on aida64 stable, what do you think?.

 

[teppic]

If your temps aren't reaching 60C under stress then you can safely increase the voltage.

If you're getting 15 mins stable, I wouldn't be surprised if 1.265v is enough.

I have set Vcore to 1.3

4.6ghz No display
4.5ghz Rebooted
4.4ghz stress testing now

My temperature are on 60-62c max this seems really low for haswell ?.

 

[teppic]

You need to settle on a voltage or a clock to test against, not change them both at once - and a jump from 1.25 to 1.3 is too large really.

If 4.4GHz is fully stable at 1.3v, then drop the voltage little by little until it isn't.

I know it's very early days, but does anyone know if the F6 is any better for OCing than the F5 BIOS?

 

[teppic]

I'm quite impressed with the board. I'm running at 4.5GHz with a voltage of 1.285v. I just ran a full Linux kernel compilation across all 4 cores (8 processes) - this is much better than prime95, as it runs the system in a much more realistic way. No issues at all with the compilation and temps didn't hit 60C. On my previous Maximus Gene, I needed around 1.31v to do this at 4.4GHz.

I'm experiencing booting issue with this motherboard - it keeps switching on then off on boot. I then unplug for a couple of seconds and then it boots into windows (not always).

Any ideas?
