Problems Overclocking 3570K on Gigabyte G1 Sniper 3 Z77

Hi,

So I seem to be having issues with OC on this board. I am pretty new to this, but have had help form other forums and have read multiple guides; problem is all the info seems to conflict and I am having huge problems getting things stable.

My system is: Silverstone FT02 - Gigabyte G1 Sniper 3 - i5 3570K - Noctua NH-14D - 2x Samsung 830 SSD - 8Gb Samsung Green Ram - GTX 480 (Temporary) - Corsair AX850 PSU

I have tried using both fixed voltage and offset dvid methods and am simply unsure if i am doing something wrong. I also have the issue that on the f7 bios my ram will not OC without errors, but will on the f8h Beta, which in turn gives a poorer cpu oc.

To give you an idea, on f7 using fixed voltage I can get it stable up to 4.3ghz at the stock voltage (1.164) with turbo llc and pll o/v on auto, but whilst it boots at 1.205 for 4.4, cpu-z shows 1.284 under load, which is weird. it takes a fixed 1.295 set in bios to get stable at 4.5ghz, which shows 1.284 in cpu-z and drops to 1.272 under prime. all energy saving, turbo etc are off.

Using offset method, vcore "normal" in takes +0.030 to get stable at 4.5ghz with all the energy saving on. This yields 1.320/1.308 vcore in cpu-z.

I cannot OC my Samsung Ram at all it seem on the f7, it just does not like it. On f8h it will go to 2133, but it takes 1.368vcore to get stable at 4.5

Now from what I have read these vcore setting are high, people all over seem to be able to get 4.5 at MUCH lower settings.

Some say that when using dvid offset then all energy saving should be on, other s say disable c3/c6. some say turn off llc and oc without it and others say set to turbo. I have been at this around 3 weeks and it is starting to drive me a little mad... really what I am after is a stable 4.5-4.6.
