Speedstep kills stability?

post #1 of 8
Thread Starter 
I seemed to have a stable overclock at 4.2GHz 1.29V, over 3 hours in prime 95 stable.

I turned speedstep on it bios and it cant reach 5 minutes, I just turned it off again and I'm not getting any issues once more (touch wood).


I didn't think speedstep was meant to cause instability issues : /

That is odd, but by any chance does SpeedStep raise the voltage as well?

Or is that Turbo Boost?

So far as I knew speedstep only allows the OS to change the multiplier to save power while not under load.

(user guide: the cpu speed is controlled by the operating system)

An increase in voltage I can't see being an issue, my temps didn't get above 66oC

I'm guessing the sudden change in clocks would be the perpetrator here. When it goes up, the voltage changes as well and perhaps not quick enough, so it would cause instability when overclocked. It works at stock speeds because it was designed to.

Heh, I guess 1.4GHz is a fair way from stock speeds.

is there any real need to have it active?

only if you're really that worried about saving power.

I'm thinking this...

It goes up and doesn't have enough voltage in that moment so it just crashes.
