I've been running this mobo for the last couple of days but for some reason I don't seem to be able to change Vcore at all. I'm currently clocked at 4.5GHz stable but can't go any further with my 2500k.
For some reason whatever I set my Vcore to in BIOS the BIOS always reads current Vcore as 1.224V. Obviously to get past this 4.5GHz mark I'm going to need more than this but as I say, I don't seem to be able to up it.
Has anyone else had this issue or do I need to change one of my other settings to allow this to work?
Cheers

What bios are you using? Im guessing its a pretty early one as you havent told us its been upgraded - possibly just the way the voltage is being displayed by the bios.

Also if you've got speedstep/energy features on it wont report in bios what it'll actually be using under load, because of course, its not under load, not to mention LLC compensating for vdroop etc...

Before just cranking the vcore higher and higher and not seeing that number jump I suggest updating to at least bios v1.7 or 1.8b7 if you dont mind a beta, then monitor the vcore under load in windows 7 using prime95 blend and CPU-z 1.56.2 - this will display correct current vcore and you'll see the max vcore it'll ever draw as you're stressing everything.

At 4.6ghz mine reports this:
Bios vcore set at 1.300v
Bios reports 1.288v
CPU-z reports 1.312v (idle 1.6ghz), 1.344v (moderate load, gaming, prime95 small FFT) but gets as high as 1.352v (prime95 blend) - probably becuase of the memory controller usage.

Best to see what the max used is before requesting more from bios. Im using all energy saving/speedstep features with an OC acheived using turbo per core multiplier only (all set at 46 for 1-4 core turbo)

Hopefully that helps, if you get stuck finding the beta bios, there is a good thread with links to them somewhere in the motherboard section.
 
Bios was on V1.4 so I've updated to 1.7 (not keen on using a Beta tbh).
Problem seems to be resolved though, BIOS now shows higher Vcore as does CPU-Z. Hadn't realised CPU-Z voltage was never changing whilst using BIOS 1.4 but now it's cranked up to 1.288 (from 1.216) with V1.7.
Thanks for the suggestion.

Max temps of 55 under full load still. 5GHz here I come :P.

EDIT:
Now getting max temps of 60C under full load at 4600MHz with IntelBurn Test and a max draw under load of 1.328V. At 4.6GHz with the lower Vcore it just crashed on or before boot, it's now stable under 20 runs of IBT, time to overnight PrimeBlend! :D
Out of interest what temps are you getting with your setup and what are you using for cooling?
