OK I've done my homework, but I just want to run it by you guys that I've not missed anything.

I'm overclocking an i5 2500k on a Z68 Ext4Gen3.


  • Spread Spectrum off
  • Base clock left at 100Mhz
  • Ratio at 40x +
  • Increase vCore as needed, probs aim for about 1.25v
  • Memory voltage at 1.65 using XMP profile
  • Load calibration at Level 3 or lower
  • Max current at about 250mA
Anything else I should check?

Obviously there are no set values that are guaranteed to work, I'm not new to OCing, I'm just new to sandybridge.

How do I stop the CPU from flicking between a low power 16x and normal 40x? I want to jsut have it OC'd to 4Ghz all the time

Cheers!
 
I doubt it'll work with less than 250mA :D
Generally looks ok. You could leave Vcore on auto to see what it thinks it needs to start with, then manually lower it from there.
 
Try the auto OC profiles first, you might be surprised, this will give you an idea of the settings the board picks then you can work on lowering the volts manually then set up the offset, so it clocks down and lowers the vcore when not in use.
There's no point in having it running at full speed 24/7.
 
All the OC profiles worked for me, At 4.8 it did start to push more than 1.4vcore, but temps were still fine, and i dont see an issue with speedstep read a lot of posts that its pointless disabling at theses speeds.

I ended up with
Multi Set to 45
Spread Spectrum Off (i've noticed this mess's with your FSB speed)
Ram set to 1600 (as auto ran at slower speed)
Offset -0.005, which seems tiny but i was running at 4.6 and 4.8 trying to find lower vcores, ran into other issues due to gfx card so atm just making sure the computer is fully stable. Been good past 24hours.

Cpu-z Shows vcore as 1.264 (but it does change, normally only lower numbers)
Astrock XT Utility shows vcore as 1.264
CPUID Hardware Moniter Shows 0.95v min and 1.30v max, although current is 1.26v and i've never been able to see anything else report that 1.30.

This is all under full loard, CPU/GPU running bonic projects... have used IBT and Prime95 also.
