Hey there, made this post purely to get a bit more knowledge and with a bit of luck, an overclocked CPU.

I'm looking to overclock my CPU and everywhere I've looked (BIOS, AMD OverDrive, AMD CCC) I can't seem to overclock my system. Whenever I opem AMD OD I get a message saying it could not find or support the chipset on this computer. So I'm a little confused, I read somewhere it might be the chipset in the motherboard, of which mine is Gigabyte M68MT-S2P (Nividia GeForce 7025 chipset). Does that have anything to do with why I can't overclock?

I know computers quite well so please don't lecture me on how novice I am, but when it comes to overclocking I am newish to it and there seem to be lots of conflicting suggestions on the web.

Here are my specs -
AMD Phenom II 955 Black Edition (@3.2)
8GB RAM
AMD Radeon HD8650 1GB
1TB HDD
Gigabyte M68MT-S2P

Thanks in advanced!

Supposedly, in BIOS you press Ctrl+F1 and it unlocks a few more options. You're looking for 'CPU Clock Ratio' (multiplier) and 'CPU Frequency' (FSB).

I wouldn't increase the voltage above stock with that motherboard though personally and just see what you can get out of the CPU with stock vCore.

I'm not sure if you can overclock on that motherboard, it certainly isn't intended for it with no heatsink on the VRM's and a 4+1 power phase, saying that, there might be a BIOS update that unlocks the multiplier and voltage.

AOD is not compatible with nforce chipsets. Read your motherboard manual and use your BIOS.

OK to start with what revision is your CPU? you can easily find this using CPU-Z from www.CPUID.com

AMD-OD is, IMO, useless for overclocking. I have tried to useit many times it it never worked properly. It is good for reading newer CPU temps but that is the extent I have found it useful.

The best way to OC is using the Bios because it can give you a higher and a more stable OC. But since you seem new to this you have an option to use what Gigabyte calls Easy Tune 6. This program is downloadable through there web page for your board. http://www.gigabyte.com/products/product-page.aspx?pid=3726#dl

the revision is important for us to know the voltage setting to get you started. the first release needed more voltage than the C-3 revision.

Also your motherboard only has a 4 PIN CPU power line which will hurt you in the OCing category but you should still see 3.6 minimum of an OC out of it. Also be sure to monitor your temps as they will jump as the voltage is increased. for the Phenom II's you could, with a high air flow case, could go 400 MHz over the stock with the stock cooler with the C-3 revision many time with out a bump in voltage. (assuming your board setts the voltage to 1.38V for stock.)

hope this gets you started :)

Different board manufatures call the part of the bios that controls the CPU something different. Also even the same company will change the names from board to board at times. just look around for what they call either the Ref clock (reference clock or FSB) can Be labeled differently. Next is this a store bought machine? like Dell, Acer, HP, e-machines ect... ?

EDIT: Ohh ACC will not help you because this is Advanced clock Calibration. Many makers use this just to be able to turn on cores or turn them off. Your CPU being a the 955 has all cores turned on and does not need ACC.

Ok but I see nothing in BIOS other than Set Memory Clock which seems to be linked to RAM and the only CPU controls I can find is voltages, of which I don't want to touch because currently I don't believe there is a reason to up the voltages.

With regards to my CPU, CPU-Z says - AMD Phenom II 955 Deneb: Socket AM3 938
while CoreTemp tells me I have AMD Phenom II 955 BE Deneb: Socket AM3 941

so now I don't have a scooby as I don't believe I can OC a NON-BE Phenom, although I might be wrong.
(This is my motherboard- http://www.gigabyte.com/products/product-page.aspx?pid=3726#ov if it helps)
On a side note that ET6 thing crashed my system so I don't fancy re-installing that.
EDIT: Also the Revision is RB-C3

DUDE YOU ARE A LEGEND! After countless hours of messing around in BIOS and me feeling like a complete and utter fool, it's simply CTRL+F1 !!! Thank you so much man!
