OC 2500k help

[grandpatzer]

I own a locked Intel i5 CPU, it was wery easy to overclock I just changed multiplier and vcore

But soon I will own a used 2500k that does 1.45v@4.9Ghz.
However I have quiet PC and cooling is enough for 1.2-1.32v only mostlikely unless I crank up the fans.
In IBT I will make sure to not Exceed 85c at highest core when running 20IBT.

Considering it does 1.45v@4.9Ghz I'm going to start by setting vcore to 1.20v and 42x100 for 1.20v@4.2Ghz.
Is this OK? Is there other sh*t I need to enable/disable tweak?

In case it passes 5 IBT I'll keep increasing speed by 100mhz until PC crashes
Then I'll decrease 10-50mhz and run 10ITB until it chrashes

Finaly I might run 20IBT to make sure it's 100% BF3 stable

Depends if you want it to be able to throttle down when it isn't loaded, if so don't use manual voltage use offset mode instead. Try it with no offset at 42X100 and increase the offset by 0.05v up if it crashes or down if it is stable. Rinse and repeat until you find the lowest stable voltage then knock it back up one notch just to be sure.

So If I want to it undervolt in IDLE I should use offset?

So let's say the VDID for my CPU is 1.3v I put offset to +0.05v, then when LOAD the voltage is 1.35(?)

Then when in IDLE the voltage is something like 0.9v(?).

At any amount of CPU load, your effective Vcore = VID + offset
