AMD® Phenom™ II Overclocking Thread

9-9-9-25 1.65v?

I have no idea what they all mean or do though. :/ (Apart from the voltage).

I can't work out why it's unstable at the same settings in a different board...
 
1.65v is the max operating voltage for these dimms. :/

They only need 1.5v at 1333mhz.

Does it actually offer any performance gains over 1333mhz anyway? I read somewhere I'd be better off experimenting with tighter timings instead.
 
at stock mine are 7-7-7-20-27-1t 1.7v (something like that) but i had to up it to 7-7-7-20-28-1t 1.75v

+0.05v won't hurt your ram / cpu/ motherboard... some boards under volt on the ram

tighter timings are better.

I am an overclocking noob. And I am lazy. So I bought the Crosshair IV to make my life easier. Cannot get my 965 x 4 above 3.7Ghz, though I am using the auto tune function. :o

I would like to try and boost this up a little if possible, but need to do it manually. The CPU has a nice Baram cooler with a Noctua fan so is staying nice and cool.

Can anyone advise me on what to tinker with? Thanks. :)

AMD Overdrive -> Preference -> Advanced Mode -> Performance Control

Start upping your Multiplier by .5 increments. Should be 100mhz at a time. Do exhaustive testing on every increment. You will have to start upping your volts soon as well. Everything is done in the Advanced Performance Control section. Remember, tiny increments.
 
I'd do away with the programs and do it all from the BIOS. The old fasioned way. :P

On the 965, the best way of overclocking IMO is on the multiplier, so drop the FSB back to 200mhz, and up the multiplier and the vcore. 3.8ghz at 1.5v is a good starting point, if it's stable, up the multi, if not, up the vcore. 1.55v is the limit for the 965s.
 
Cheers for the responses chaps.

I have been trying a few things out this afternoon. I am going to stick with the ASUS Turbo V Evo program as it is familiar, and it also links directly to the BIOS and changes it for you. saves me going into it and getting all confused. :)

I have managed to bump it up a fair bit and will run some Prime on it later. Looks ok to you? Just a shade under the magical 4Ghz. :)

If it runs stable, GPU is next.

Mine would, but your's is a C3 so I dunno. Mine wasn't stable at 4.0ghz with 1.6v being forced through it. (Chronic vdroop to contend with though).
