The OC on my gladiator carbon.

[silentnight79]

Seems they have stopped selling my system straight after I brought it round three weeks ago, but anyway my question is, is it normal that even though aria's oc profile has been selected in the BIOS, this override clock is not then showing in Windows 7 ultimate 64? It's just reporting It's stock CPU.clock ??? Should be 4.5. It's an Intel sandybridge 2500k.

run cpu-z to see the speed... then use prime95 or similar to stress the cpu.

cpu's throttle back when not being used to save power :)

[silentnight79]

I've ensured the power profile doesn't throttle back unless Intel does that regardless. I have seen the overclock reported correctly in cpuz though to be fair.

[Spaceboy]

Sounds like it's working fine then :)

There's probably another bios option to stop it, but why would you want to ? ;)

Glad it's working :)

[silentnight79]

I only mean the power usage profile in windows itself, I've changed no setting in the BIOS as I hoped aria did all that for me !p

[Spaceboy]

Ah right, that's cool then - the windows power profiles won't have any effect on the cpu clock speed afaik :)

Silentnight my Windows 7 install also shows my CPU at stock 3.06GHz, but CPU-Z shows it as 4.2GHz :thumb:

[Speed]

The only change Windows 7 power profiles can have to CPU speed is through Speed Step, where it throttles back the CPU speed at idle. Setting the profile to High Performance will show the full speed all the time as it disables Speed Step as far as I'm aware.

I'd recommend just leaving it on Balanced.

[Sniperdude]

having performance power setting enabled has no effect on speed step

if EIST is enabled in the BIOS the multiplier will be dropped when the system is idle
lowering the clock speed

I have my own system on performance power settings and my multi still drops and i wouldn't have it any other way, it lowers idle temps and keeps the cpu cooler silent

Cheers for the info guys. Much appreciated.
