Total NOOB sandy bridge overclock question

phillai · 8 Jul 2011 at 14:42

I'm what you call an average overclocker but this is my first time overclocking a Sandy Bridge CPU.

I've done the auto overclock option in the BIOS to 4.4Ghz and I prime'd it and it's all OK but is this normal?

Is it really running at 1.6ghz whilst idle?

Yes, when idle it drops down to 1.6Ghz. If you don't want it to you can disable C1E and EIST in the BIOS.

Yes, thats fine, keeps your electricity bill down when you're surfing and ramps up the multi when your running something intensive.

Right, thanks for the fast reply guys!

One final thing, is there any danger in disabling C1E and EIST in the BIOS?

The most intensive thing I use my PC is web browsing but I could have about 40 tabs or so open at once and firefox aint exactly fast these days...

The 2500k isn't going to struggle with web browsing, even at stock speeds. There would be no benefit to your turning them off, leave them be.

Thanks for the info dude!

the time it takes for the cpu to go from x16-x44 (or even x50) is fractions of a second, so you would never notice it. why have it running more volts and hotter when it doesnt need to.

C1e to C0 is 10nano seconds (0.00000001 seconds)
C2e to C0 is 100nano seconds(0.0000001 seconds)

Why overclock for web browsing? :confused:

would it not improve several windows with several tabs?

I really doubt a quad core CPU at 3.3Ghz would give two stuffs about web browsing irrespective of the number of tabs. Might be wrong though.
