"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."

OK, so I was bored yesterday and decided to try the above. I figured I would post this just for more info on this batch #...

I tried 57x and could not boot into Windows, doesn't get past post. Is it worth upping the vcore to like 1.58 to see if 57x flies?

Not really going to use this CPU that high as I don't have the proper cooling, but was curious as to my max multi.
