Okay after following a guide on youtube i've managed to achieve 4.0 ghz although I'm wondering if I can go higher? as my temps are only @ 40oc and what I'll need to change in the BIOS to achieve it. All help would be super appreciated !
CPU: i7 920 d0 chip
CPU cooler: Cooler Master Nepton 240M Liquid CPU Cooler
RAM: G.Skill Ripjaws X F3-12800CL9D-8GBRL 8GB (2x 4GB) DDR3 1600MHz Dual Channel Memory Kit -
Mobo: ASUS p6x58d-e
EDIT:
Managed to get 4.4ghz without hyperthreading @ 65-70 temp max load if anyone has any suggestions let me know
Here are my current settings

Your ability to tweak settings and your persistence will significantly impact performance, but without an unlocked multiplier, you're likely capped around a few hundred MHz. Still, if you're knowledgeable, 4GHz can be a viable option.

While your OC skills and patience will help, without an unlocked multiplier you're likely capped at a few hundred MHz. But if you're confident, 4GHz is possible:

Your d0 chip could be the key.
I've updated my post—what changes would you need to make in the BIOS?
