First things first, these are my specifications:

Gigabyte Z77-DS3H
Intel i5 3570k
4gb Kingston HyperX Genesis Grey (2x2) 1600mhz 99927 1.65v
GTX 560 oc
Antec One case
OCZ 500w corexstream psu

Bought this from ocuk a week ago, been tweaking around with it.

I can get 4.3 (43x100) stable with auto voltage, or then 1.2v (although I haven't tried any lower than this), I was using CPU-Z's auto voltage reading to select a custom voltage for this. Stability on prime95 for a few hours, 3dmark and some games etc.

I have tried to put this to 4.4 (44x100). Won't even boot into windows. Manual voltage increase up to as high as 1.3v, still nothing. I tried changing my memory voltages (DRAM) to 1.64v (my mobo doesnt offer 1.65v?), still nothing, it's set to 99927 1600mhz as advertised.

Have I got a really bad cpu or something? Just one more multiplier and the thing is as good as useless. Does OCUK have some tips for me?
 
I think that the Gigabyte Z77-DS3H is just notoriously bad for overclocking? Am i right in believing I should upgrade the motherboard? Still can't get it past 4.3, and am getting some strange instability issues at 4.3
 
When I was first looking for a Z77 board that one was on my list. However I thankfully found out that it was a restrictive board, in regards to its bios settings. It should have been called the DN3H as the N would be for Neutered.
Instead I ended up with the D3H and that has some great and regular bios updates and it is highly configurable. Mine ran at 4.4 fine. I'm not sure what is missing or there in your bios but I would have thought that you should have been able to get it into Windows at 4.4, stability is something else.
My D3H is now spare as I have a UD5h.
 
Vimes as you have the Z77-D3H and 3570K any chance you could save the profile from your bios or do some screenie's at all as i'm just fiddling about with the same setup myself atm
 
Alas I can't do that as it is now spare, as noted, and all boxed to sell - when and if I get round to it.

All I did was to select 44 as the multiplier.
Put the llc on norm - important.
Put the offset voltage to 0.06v for the vcore.
Disable the iGPU.
Manually adjust my memory voltage to 1.35v - for my ram.
Set the memory timings to 9.9.9.24
Set the reaction time to fast for the core voltage change.

The above is from memory and allowed me to run at 4.4 without issue but each chip is different. I used all the turbo features of the chip so that it idles at 1.6.

Hope that helps.
 
I couldn't find any option for LLC, offset voltage or a reaction time for core voltage change.

My bios version is F6 (apparently the latest).

Still stuck with my lowly 4.3ghz. New motherboard?
 
Only get a new board if you really feel an extra 100 to 200mhz is worth it for you, and then there are no guarantees.
I would doubt that the 3570k at 4.3Ghz is the potential bottleneck when you have a GTX 560.
