AMD X6 1090T OCing with High voltages

post #1 of 6
Thread Starter 
CPU: AMD X6 1090T BE @ 3.9ZGHZ
MOBO: Gigabyte GA-MA785GMT-UD2H
cooler: air cooled after market (don't remember the brand, but its pretty decent) cooler

I can't get my CPU stable at 3.9GHZ with voltages less than 1.5V. From reading around this quite a bit higher than the average. On top of this I can't even get the stock 3.2GHZ with voltages @ 1.374~1.4V. Which also seems to be trending higher than average. Temps stay between 53-55C and get a bit flaky above 55C. If I keep the temps down 3.9GHZ stays stable for days of 100% CPU usage.
I have the best success when I keep the voltage settings on 'auto'; manually putting the mobo to 1.5v won't stay stable. Im using the stock clock frequency at 200 MHZ. Could I get more stability with a higher clock freq and lowering the multiplier and then perhaps lowering the voltage as well? Not sure if all of these are related.
Thanks in advance

You do NOT want to be OCing a Phenom Ii x6 with high voltages on a setup with a very low quality 4+1 phase setup that is known to have issues pushing TDP.  Back it down and return the stock cooler to its rightful spot to ensure motherboard component cooling, if you don't wish to (you really should) consider looking for a new, overclocking-ready board with a QUALITY 4+1 phase VRM setup as a minimum and VRM cooling.  Read more about why this is important: About VRMs & MOSFETs [in signature]

What's the CPU NB freq at?

+1 to xd_1771 on the dangers of 4+1 phase set up and 6 core stupidity. Educated me right out of doing something crazy without realizing the possibility of blowing my mb!

I appreciate the info, will look into a new board, in fact I think I already found one. Don't have the stock cooler anymore, but I can rotate it in any direction. I'm assuming the component that needs to be cooled is the Heat sink below the cpu...

My NB freq is at 2.4GHZ

Glad I found this forum! Thanks again

What type of board are you looking at? Also, if you can, find out the name of your cooler. I am in the process of reworking my OC on my 1090T right now and I am running an 890FX UD-5 Gigabyte. Had it up to 4.2Ghz on this board so it is solid. I think though you would be looking at the 990's boards now. Also using Prolimatech Megahalems for my CPU cooler. The chip used to be under water but isn't right now.

Actually I'm probably going to put oc'ing aside.I want to shift over to intel anyway.....
All is back to normal....thanks again for the heads up, and possibly saving my board/cpu
