2500k Questions (Mostly Turbo)

post #1 of 3
Thread Starter 
I haven't overclocked for a few years (i7 920) so I forgot some stuff. Anyway, I got a Corsair H80 water cooling system, ASUS P8P67 DELUXE (REV 3.0) motherboard and the i5 2500k.

I just ran the Asus auto detect extreme overclock software where it try's to find your highest stable overclock. It got up to 4.970 GHz and It was running way too high of Core Voltage so I did it again and got a 4.8 GHz OC at between 1.43 V - 1.5 V when running tests. It never got over 60c. But CPU-Z says my core speed is 1648.50 MHz until I run a program. I disabled speedstepping in the Bio's and it still says this. Is the 4.8 GHz overclock only a turbo speed overclock? My i7 920 was a 3.4 GHz core overclock.. I went into the Bio's to manually overclock stuff but I just saw turbo speed overclock settings. Is there anyway I can change my core overclock? Also, how can I have it a constant 4.8 GHz?

No point turning the power saving features off. Just leave them on. The technology is so good now that it won't hurt performance.

ASUS overclock most likely overclocks the main multiplier and not the turbo multipliers. Go and have a look in the BIOS you should see the changes there, on my ASUS motherboard the main multipler is under CPU power settings - or something strange like that.

I just see in CPU-Z my core voltage goes up to 1.5 V sometimes 1.525 V when it is running a stress test, but mostly is at 1.45 V.. What is that Asus auto OC tune software done to allow the Core Voltage to bounce around from 1.4 V to 1.525 V? That seems too high to me.
