"Thanks for the input guys!



Binning Sandy Bridge is extremely easy.

- use HS fan with easy mounting
- set Vcore to 1.55V
- disable HT and 2 cores (to not make it overheat with crappy HSF)
- increase multiplier

You just need to see the windows OS options, not actually boot into windows. If your CPU can show the different OS options, stability will just be function of Vcore and temperature. If it doesn't show the OS options, you will never get it stable anyways, so you might as well ditch the CPU.

Usually, it takes about 5 minutes to see if the CPU is good or not.

With some CPUs, you do have the issue that some multiplier is better than the other for stability. For instance, my current CPU can boot at 51x MAX (~ 5145MHz). When trying to run near this max speed, I have to use 49x instead of 50x multiplier because it's a lot more stable.

But, that's something you don't need to test. With BCLK adjustments, you'll never get 5200MHz going or so. Multiplier binning is the best way."

Can anyone expound this idea further, since I will be getting 2x 2600K's and I need to know which one to keep in 2-3 days time only.

And whats the max voltages for VccSA/Vcore/VTT and vDIMM you guys can recommend for 24/7 usage under air cooling. Will be cooled by a Noctua D14.

From what I've been able to gather, Vcore = 1.400 , QPI/VTT = 1.1 , vDIMM 1.72 , VccSA = 0.971
