2600k 4.6ghz overclock question

post #1 of 8
Thread Starter 
Hi, I have a 2600k, asus p8p67 deluxe, and noctua u12p cooler. The 2600k is overclocked to 4.6ghz in offset mode +0.120, voltage is at 1.296. After running some stress tests, my max load temps was 78c. I think that’s pretty high and I noticed my voltage jumping as high as 1.36. What do you guys think? Should I be using offset mode or manual mode? Help appreciated. Thanks.

Manual mode is better in some cases since you have more control over the vcore, however the voltage won't drop when speedstep kicks in.

looks fine to me. if the temps hit 80c, I would advise throttling it back a bit though.

offset mode is better in my experience, since during idle, it'll drop voltage along with clocks

If I were to swtich it to manual, can I just set it at 1.3v and start stressing it and see if it is stable?

Thats because you have the Load Line Calibration set to Ultra High Am I right?
That raises your peak voltage, your default voltage should be around 1.255 or 1.260V plus .0120mV added up results in 1.360 (aprox)

Try to lower the offset to 0.010 and the LLCalibration to Ultra High and youll see the difference in voltage and temps, I think the sweet spot for a 2600K is 4.6 ghz with 1.295 to 1.32V,

set the LLC to level 1 so that the vcore will stay close to the setting of vcore you applied, underload. In this way, you can easily configure your OCs as vcore will not jump to higher figures unexpectedly.

Do not set LLC to level 1. Always avoid level 1 if you are OC.
It makes you reach the desirable vcore better (lower, since there is less vdroop) at level1 but at the same time you are risking your cpu to get damaged by unwanted voltage spikes.
LLC is there to prevent that set by the motherboard company, not from intel.
So someone who uses off-set but use LLC level 1 doesn't make sense...
Save the voltage at idle but allow it to risk getting more spikes on load...?!!?
Using level 1 on lower clock (up to 4.0~4.2 or so) should be fine since it only uses lower voltages overall anyway. (so the voltage spike won't reach the danger zone.)
