Thank you for the confirmation. I won't be using gigabyte boards in future builds.

So I guess it is not that of a crappy chip, BUT it just won't do 4.5/4.6Ghz with a reasonable vcore. It needs ~1.4 vcore and 2.1 input for 4.5

I have no idea how much it needs for 4.6 propably 1.45vcore. Obviously I haven't pushed it that far because i'm under air. (Thermalright Macho HR-02)

Also for 4.2 it already needs ~1.175-1.2 vcore (haven't tested it enough to be sure)

And for 4.4 already ~1.275 vcore.

What do you guys think is a safe 24/7 vcore? Is 1.275v ok?

Look into enabling C7, it will lower the VCore significantly and never peak unless you're under fairly heavy load. Unless you plan to do some serious gaming, you can ramp up your VCore and not have to worry about degradation or heat 24/7 because you'll never be close to your set VCore.

You crash on stock? Start diagnosing why.

You don't crash on stock? Underclock RAM and uncore by 1 notch and work up slowly

(this is assuming you mean like prime27.9 fft 1344-1344.. i have no idea what it takes to make 28.3 blend stable, but same methodology should work)

no stock i can run it for a minute
on any 4ghz run with any combo of things i crash.
the only one i have left to try is brute force run with like 1.15v on vcore.

talking 27.9 on blend and 1344

What are your temps when you are at stock and full load?

62-ish

71ish at 4ghz under ibt.

Meh. Plenty of thermal headroom, but couldn't get 45 stable at 1.350v and don't want to push farther on Mrs. B's machine.

Can someone explain the system agent values. I read a guide that suggested +0.10 but when I type it it shows 0.100 looking like 100. Did they mean just add plus ten or actually type 0.10
