so far all is stable and working fine. temps are also ok https://lh3.googleusercontent.com/-n5MdGro2xYM/UcD10bUJ4yI/AAAAAAAAFS0/-GPHPddONB8/w1358-h585-no/45ghz100stable.jpg
now if i try only 46 ghz and leave uncore on 45 i dont get it stable. screen freezes after like 10-15 seconds of intel burn test.
i tried everything more vcore like 1,3V or 1,35 more VRIN to 2,2 more RING, everything set to extreme. no matter what i do it isnt stable but 45 ghz are 100% stable so i dont understand that.
i also tried the new beta bios (F6g) but the funny thing is if i overclock in that new bios like i did in the old i cant even get my pc to boot in windows. it freezes on win8 loading screen instantly.
it feels like my cpu needs some more voltage for i dont know exactly what but it isnt the vcore for sure and gigabyte cant provide it for me
i think perhaps your uncore is too high, a new batch of these betas have brought a fix which allows uncore frequency to change. So while in a previous BIOS it might not have changed, now it will, and you will be hit by a huge surprised which is how Uncore can hurt your OC big time. Set your uncore to 35x and then try your CPU OC and then raise it once your CPU OC is stable. If it makes your CPu OC unstable then you will need to increase vRing, also vRing can help stabilize your CPU OC. I am not sure why you can't get above 45x, maybe it is just the CPU. For kicks you can try 1.4v vcore and see if it will boot, but even at 1.35v you don't want to bother with 46x b/c of the heat.

I've been using the F5 BIOS, which is the latest official. I play with the beta BIOSes a bit too and they seem to conform more with everyone else's results.
yea might as well give it a shot, or just flash the BIOS again.

Also, setting the vcore to 1.22 and multi of 44 it seems just as stable/unstable as stock. i.e. I can fold, stress test and game ok, but there are occasional 124's.
I have only once been in front of the monitor for the BSOD, mostly it happens overnight or while I'm at work. The CPU is folding away 24/7 so it is always loaded. Temps never above 82C.
My PSU looks great on 12v, 5v and 3.3v but it is rather old. I may drop the $80 for a new one just to rule it out as a cause.
Are you measuring your voltage rails with a DMM or are you using hwmonitor or easytune? I would look to your PSu first, seriously, if a $80 PSu is an upgrade, IDK what to say to that. PSu is very important with haswell, i had many issues in the beginning when I was away from my home and I had to use an older PSU, it almost killed a board of mine. The board worked fine for a few hours, then all of a sudden BAM it wouldn't boot at all, not even start up. I ended up replacing the PSu and first boot on first try and no more odd issues I had with the other one.
You should also run memtest86+ on your memory.
Also clear your CMOS, but I don't think it is the board, if it is the board then it is a defected board and you will need RMA. However also look at your OS make sure everything is in order, and also maybe reinstall it if you can.
My guesses in this order:
Of what is causing your BDOS at stock.Edited by Sin0822 - 6/19/13 at 11:44am
