** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

[Touche]

yes bro.,i set the vtt 1.20 in bios.,1st i set it to 1.24.,after successfully boot windows.,i revert back to 1.20 to see if still can boot windows.,and the i'll try priming fo 15minutes..everythings fine.,only one of the core abit hot..is the settings ok bro..

Those are really nice voltages, but try Prime/OCCT for >10 hours and IntelBurnTest >30 passes to see if it's really stable.

i seem to always want to flash bios back to F4 (i actually like F3 version if it had an ability to save and to retrieve a saved cmos setting profiles from USB drives),

i think F4 is the best bios file for me already, however, i will continue to try newer bios files at whenever gigabyte releases them and once i don't find an importance improvement in bios at my end i will keep on going back to F4.

Why do you think F4 is the best? Does it allow lower voltages for the same OC or...?

I have an EP45-UD3 and e7300. It's nowhere near as good as all your e8x00 it seems. It needs 1.35v in BIOS for 3600 MHz, but anything above that requires a big voltage increase. 3.75 needs almost 1.42v and 4 GHz would probably take >1.475v. I've read it is not uncommon for e7x00 to require much higher voltages than e8x000, is it true?

In the end, I've settled for this. It's >12h OCCT Mix and 60 pass IntelBurnTest stable. Can you tell me if temps/volts are ok for 24/7?

BTW How come Tcase is higher than core temps?
