Having a lot of fun with this B85 combo. Screenshot from this morning, still using the stock heatsink...
I am working on a min-voltage 3.8Ghz preset before moving to higher clock speeds. Right now I am stress testing at 1.135V - dropping to 1.120V results in BSOD just as the boot cycle completes. I think I settle at 1.140V for the preset.
Clearly, I didn't win the silicon lottery. The motherboard isn't very easy to work with, but for the pocket change I shouldn't complain.
Overall, I'm pretty impressed with the value I got out of this deal.
