Need some help ocing 2600k to get stable 4.6ghz

post #1 of 7
Thread Starter 
I ran prime 95 for 17 hours without no errors or bsod with these settings.
1.35v vcore
1.700v cpu pll
1.5v dram
everything else auto disable speedstep and everything..

i changed it to 1.34 trying to bump down some voltage but was unstable so i put it back to 1.35v but its not stable either so im using an offset mode with +0.010v and same setting as above u think it be stable? for a 4.6ghz oc?

Dunno, offset is relative to your DVID, not your vcore...and we don't know what your DVID is.

At higher overclocks cca 4.4 + GHz you MUST have PPL ENABLED (not auto) and power supply set the way you do not have voltage drop in load.

I am using following settings on my ASUS P8P67 board:

LCC Ultra high
VRM 350 Hz
Phase extreme
Duty extreme
CPU current 130%
VCCSA 0,95V
VCCIO 1,1V
PLL 1,85V (the same as default)
PCH auto
CPU spread auto.

4.6 GHz is quite probable frequency at 1.35V, but guaranteed. You may reach just 4.5. Or more wih proper settings.

Well I read elsewhere that PLL Overvoltage is only really usefull with 4.8Ghz overclocks, and that the PLL could be reduced to 1.7/1.71 volts with Spread disabled for a more stable OC. Try this template if the other ones don't work.

I can't see your mobo but give .050 offset a try with CPU current at 120% for my 4.7 I have my internal pll overvoltage off and my pll at 1.725v and phase control on asus optimized with high llc (50%)
