Ohhh, I got it, it was the application that switch between my discrete GPU and the integrated graphic, I will have it uninstall anyway. Is there any specific setting you guys would suggest? I really want to get to around 4.5 GHz smile.gif

so put a 45x multiplier, start at around 1.2V and keep addoing voltage until it boots and is prime stable for atleast 5 mins, if it is stbale then do a 12 hour test.
E.g is 1.2V doesn't boot go to 1.205V etc...

Values from the software does not stick.

Only values entered in the BIOS sticks.

Z77 oc formula official P1.6 is lastest bios which is based on 1.42k also fixed some bugs and fully win8 support

Thanks, this fixed the issue with changing the BCLK in Windows thumb.gif

New bug noted:

When setting multiplier to 'per core' and have 1 core to go up 1 extra (eg 46,45,45,45), the BLCK jumps around like crazy when viewed in CPUZ. It is perfectly 'stable' when using the 'all core' setting. I also did not note it ever hitting 46, but rebooted quickly due to 'floating' BCLK.

Thanks bro, sound like you go with fixed v-core voltage? I did crank my multiplier to 45x and it crashed to dead blue screen right away, but at that time I believe my voltage was auto. I'm currently with offset mode now. I will give it a try

Would you guys consider 1.43 VCore too high with a 2600K if used in offset AND all C states enabled so the only time it ever hits 1.43 is when it's needed? Current also stays low as the wattage used is about 40 watts less at idle than fixed VCore and VCore also gets down to .96 at idle. This is according to HWiNFO64 with a 4.8 GHz setup.

Try to stay below 1.4V 24/7!
Use a fixed voltage when overclocking dude,makes it alot easier, you don't need 1.43V for 4.5Ghz, well i hope not.

With a Z68 Pro Gen3 I was at 4.6 GHz @ 1.38 volts with all C states enabled. Very stable. I'm trying to do the same with this board but at 4.8 GHz. I think you're right though, anything about 4.6 is going to take fixed voltage and C states disabled. I'm now finding out that I can't stay away from lockups at idle. Temps and load don't go up with high voltage, it's the current that draw the wattage. Soon as I disable C states my power consumption goes up 40-50 watts and temps go up an additional 10°. Not that it's a big deal, just challenging to find a happy medium between efficiency and overclocking. This board like to go lower on the idle VCore than the Pro Gen3.

Lucid MVP basically uses your discrete gpu and the cpu's chips graphic in conjuction together to form an sli type function. You can read about it more as there are plenty of articles out there for it. Anyone that's not running discrete gpu sli will gain performance taking advantage of it. there are two different configurations. One will take advantage of the discrete for gaming and turn it off when not in use. I believe it's i mode.

I have to say I got this board last week. I don't have all my parts yet. I have to say I was very impressed with the fit and finish and when you inspect the board you know you have something very special. Nice work and I'll be posting up once I get things together.
