Hypothetical question about Thubans.

post #1 of 11
Thread Starter 
I heard Thubans are based on a newer/better stepping then typical Denebs and have better IMCs along with better overclockability even though they have 2 additional cores. Has anyone ever tried to disable 1-2 cores on Thubans in order to decrease the heat output to allow for higher clocks? I know it sounds strange to buy something then disable it, but has anyone ever tried it just to see how much they could get (clock speed-wise)? Assuming someone didn't need 6 cores, would this be a terrible idea? I heard somewhere that disabling cores doesn't really help other than in heat output, but decreased heat allows Phenom II's to OC better generally, right?

This is what I actually have done, and currently have 2 cores disabled for games. With 6 cores I can run 3.71ghz at 1.358V, but if I disable 2 cores I can run 3.71ghz at 1.3v. Temperature also drops by a lot.

That's high clocks at low voltage! Have you considered running it even higher then that frequency at higher voltage?

Motherboard limited

Maximum FSB is 275 and wont even boot at 276. Currently running 275 with 13.5 multiplier, could do 3.85Ghz but havnt gotten around to yet.

Ohh, that's unfortunate. Have you thought of utilizing turbo mode? It could get you to pretty high clocks and you won't be over the "safe voltage" according to most, which is 1.5V.

I have fiddled with that. I ran 4125mhz turbo for 3 cores for a while, could try 4400 mhz for 1 core.

I just don't like messing with the Turbo Core that much, because I have to use AMD Overdrive to change its settings. My bios only has the Turbo multiplier, not the voltage.

I always thought that turbo mode had a set voltage boots of .15V

Apparently not, you can change it in overdrive. I noticed that I can do 3.85ghz on 1.337v (leet ) with 4 cores. Strange thing is that it only required 0.02v more than 3.71ghz.

You can change Turbo Core Voltage in AMD Overdrive?

Should be able to in the clock/voltage control with advanced mode on. Just click the Turbo core button.
