Help Fine Tuning OC - Haswell 4670K

[Dirk Diggler]

I just upgraded to a custom water solution for my CPU. I've decided to push the CPU a bit further than the overclock I've had it on with the H100i.

So, rig was stable 4.3ghz @ 1.19 vcore. I'm aiming for 4.4 to start with but before I push on I thought I would post some BIOS screen shots to see if anyone has any suggestions on what I could change. Is it simply increase vcore and multiplier, or is there some subtle change that could make a difference?

Sitting at 4.5ghz with 1.29v. Getting shutdowns when trying to encode with handbrake. Is this purely vcore required? Seems a big jump from 1.19 to 1.29 for 200mhz?

Any help appreciated, even if it is just to say "shut up and up the vcore"
