Hi everyone,
So I've managed to overclock my Phenom 965 BE C3 to 4Ghz with the VCORE at 1.4875v. I have a Cooler Master Hyper212 Evo +1 fan and the temps i'm getting are 43-46C idle and 58-60C with prime and 60-62C with OCCT.
My motherboard is an Asus M5A78L-M/USB3 and I'm using Artic Silver 5 if that helps. Any help would be much appreciated!

UPDATE:
It seems like i went a bit overboard with the voltage and i can get it at 1.4750v. It makes about a -2C difference

Here are my settings from the AMD Overclocking forum. Which has some very good info and I would recommend reading.


Cpu: 975 revision RB-C3
Name: exroofer
Stepping: C3
Frequency: 4113.8
ref*multi: 200.7*20.5
CPU voltage: 1.452
CPU-NB: 1.15
nb frequency: 2600
NB volts: 1.2
RAM: 8GB 1600Mhz DDR3 9-9-9-24-2T @ 1.5V
Motherboard: Asus Gen 3 R2 Sabertooth 990FX
Cooling: Air cooling/ CoolerMaster S524 downdraft
OS: 7 64-bit

Like I said, recent hot spell pushed my ambient to 28 plus C, so I had to back it off for right now.
Going to buy a few more case fans next and see if I can leave it there all the time.

Your voltage is not excessive from what I have read.

sounds about right. My 975 at 4.1 runs right around there as long as the ambient isn't too high. Hot spell here this week, so I had to turn it back down for now. Just left the northbridge up at 2600 so the performance hit isn't as significant.
 

Oh ok, what voltage are you using when at 4.1?

Seems pretty warm to me..
I try to keep the cores under 55c
Also..that board doesn't have a good VRM setup for overclocking.It might trigger sudden reboots.
 
Well when I said temps seemed about right, I meant while running serious stress test software like Prime95.
Under normal operation usually see around 53c ish.
I should think he would not be far off that under normal operation.
 


Okay so now ive bumped it up to 4.1 on the same voltage. Also, ive had this board for over 6 months now and ive had no reboots with it
