(70C is a good load temp but its not achievable with my CM 212+)

thanks.
90's is suicidal, 80's are scary, 70's are the norm on air with HT on. I have never even approached 70 with my 212 but then again I dont use HT nor do I have a need for it. I just game and OC for the sheer thrill of the game!

3. Keep an eye on your temps, I can not stress that enough.
First of all you're using a i3 im using a i7 860 which is a quadcore CPU hyperthreaded which produces alot of heat and needs alot more voltage.

I tried those voltages and those values but they dont work.

in fact no values work, i tried adjusting the values but once i SAVE AND EXIT the yes or no dialog pops up it wont let me press Y.

so i have to restart my computer inorder to get out of that HUNG state.

ive flashed my BIOS to the latest F15 and the problem still occurs.

is my motherboard/cpu broken or something?

isnt 1.4v pretty much the max for an i7 860 vcore?

do you have any other under 4.0ghz settings i could borrow off you?

just wondering..... is the MB in your sig correct? i tried looking it up and cant find it. the closest one that i can see is a "UDP3" not 4.

That particular board is suppossed to OC very well, though I dont have personal experience with it. Could be that your chip just requires more voltage than most, which is not uncommon. Also I have noticed that the quality of PSU has a lot to do with how well your sytem OC's(not saying its at fault, but something to look into). Have you run memtest to verify that your RAM is running optimally? I know this sounds weird but I usually have to tighten my Ripjaws to 8-8-8-20 from 9-9-9-24 to be able to boot at higher CPU frequencies(odd isnt it)

Also the latest BIOS isnt always the best BIOS, only update if you need to. Maybe experiment with different versions??

yes it is indeed a P55A-UD4 which is a quite uncommon mobo if i say so myself

this BIOS issue is worrying me i dont know how to fix it

i'll try downgrading it to the first one which i remembered worked(ive tried f13, f14, f15 same prob.)

my PSU is 620w which is plenty for such a mild overclock and a modest system right?

ok

as for the PSU just saying some times its about the quality and how stable the out put is then how much it puts out.

i thought that the Vantecs were of decent quality but i did RMA the first one i bought nonetheless i think it should be working fine. first of all i need to solve my BIOS issues

im going to try every BIOS since the first release wish me luck

OK GUYS MY BIOS IS BACK...F9 and below is working due to a new revision released by Gigabyte. Damn GB lists F10+ as a BIOS for rev 1.0, what idiots...

testing for stability for:
running 1.3v vcore
1.27 vtt
180x21 <-sort of works atm, ran 5min stability test on prime95, 91C max

-191 BLCK - FAIL- instant error, dropping bclck
-185 BLCK - OVERHEAT - 90C+ Prime95

the setting of 180x21 maxes out at 91C is it safe to increase it some more?

thats really strange, a setting of 181x21 maxes out at 87C........running OCCT now

ok, ive achieved an overclock of 3.8ghz that i think is stable(ran OCCT).

.::3.8ghz overclock::.

1.3v Vcore
1.27 VTT/IMC
1.6 vDIMM
181x21 = 3.801ghz

idle temps @ 42C
full load temps @ 86C
