Trouble overclocking i7 2600k @ 5.0 Ghz

post #1 of 6
Thread Starter 
Motherboard: Asus P8Z68-V PRO/GEN3
CPU: i7 2600k

Vcore: 1.500v
PLL: 1.718v
Multiplier: 50x
Base Clock: 100mhz
LLC: Disabled

I need help getting 5.0Ghz stable. I have sufficient water cooling so I'm comfortable with any kind of voltage. I've left LLC off because it doesn't seem to improve stability for me. If you guys have any tips for me please tell me!

Do you need any other information than that?

Just because you want 5GHz doesn't mean the chip will be able to. For all you know, you may need 1.6v to get stable which would absolutely destroy your chip. Start by getting say 4.5GHz stable, see what it needs, learn about your chip, and go from there.

Honestly though, while 5GHz is awesome, and e-peen worthy, I keep my chip at a mere 4.5GHz because it's fast for what I need and more importantly the temps and voltage is low and I know it will help my chip live longer.

From what I've seen an average 2600k will need around 1.5 or so volts to hit 5ghz, I don't' run 5.0 daily since the heat is well not really worth the performance that I wouldn't use.

There's a point of diminishing returns. I need 1,33v for 4,8Ghz, but above 1,45v for 5,0Ghz.
