Did i do it right? Overclocking a 6600k to 4.6

[Bergsorensen]

Hello forum - this is my first post so have mercy!

 

Im trying to squeeze some power out from my old machine, and turned my love to overclocking my CPU. Saying im a rooky at this is an understatement! I played arround with the multiplier, and vcore and ended up with something that looks stable.

 

Does this OC look ok, or is there anything i need to worry about? 

 

 

 

A big thank you!

Currently running 4.600 ghz at VCORE 1.320 (though cpuz says a lower voltage) - power savings/modes off.

It's been a long time since I OC'd one of those, but it sounds about right ball park. I recall hitting a wall around 4.7 and voltages couldn't get too silly to manage heat.

 

How are you testing stability?

it's almost never going to be exactly what you set, and also this voltage you're seeing in CPU-Z means nothing unless you stress your CPU and see where it settles

When you stress a CPU there will be a voltage drop naturally, so there's something called LLC (Load-Line Calibration) in BIOS to mitigate that (default is Auto), which basically compensates for the lost voltage under load and pushes it higher, you might find LLC settings ranging from 1 to something, or from Low to Extreme, you wanna find the right setting that keeps the voltage under load as close as you can get it as if it was on idle, can't tell you which setting to use because each motherboard is different, Auto might be good enough though

Also LLC sometimes can be too aggressive and pushes the voltage way higher than what you actually set

From a quick research, 1.3V is around what you should expect for 4.6Ghz, try to lower the voltage as much as possible while keeping stability, and check temperatures under load

Yes, great post Syn...  Yes my LLC is at extreme or else this OC is dead man walking or I would need to set a really high voltage so when it comes down on stress it will still be stable.  Personally using LLC for many many years is the way to go.  You set a good voltage for idle and it does flop the voltage down and thus a unstable system and what not.

 

That CPU @ 4.6Ghz sounds right.  You could probably get even more, but then heat becomes a issue and we don't know what cooler you using.
