Black screen when I try to oc.

post #1 of 15
Thread Starter 
So... I just got this 955 BE yesterday, I have it paired with a 700w psu and a Foxconn A9DA-S mobo. Whenever I try to touch the multiplier (even from 16.0-16.5) it just blackscreens on boot, and my motherboard has the "OP" error displayed on the motherboard display thingy (motherboard has an LED on it). I tried googling the OP error and found nothing. Any help would be great as I would really, really like to get to 4.0ghz.

Oh also I have to reset the bios to get it to work again.

sounds like you need to increase v to cpu....do you have llc on that board?

heres a good guide for oc'ing your chip

Yea that's what I did. It still isn't working... Hmm... And I have no idea what llc is lol... It's a Foxconn A9DA-S mobo

load line calibration.....i was reading that your board is pretty limited in oc options...so you may or may not have the option

they used 1.476v to get 4ghz...what is your cpu v now?

My v is 1.344. But if I try to turn it up it black screens me as well... Even if I don't touch anything else...
post #7 of 15
found a pic of your bios and wrote the changes you can try off to the side....keep other settings where they are for now...

are you saying that even if you don't oc...just turning up the v makes it black screen?

Yes, I can adjust the voltage and it will boot fine. It's just everything else I can't touch or it won't boot... I'm almost thinking I'm not on the right bios version because there is no CPU-NB multiplier adjust manual, only clock multiplier...

Also, I can't flash my motherboard because the bios flasher isn't compatible with 64 bit windows...!?!?!??! What the hell????

a) ditch the foxconn mobo
b) get an Asus one
here's a link http://www.geeks.com/details.asp?invtid=M4A79XTD-EVO-PB-R&cat=MBB
c) profit
You may even get 3.9 stable coolsmiley03.png
