i5-2500K/2600K batch number and o/c results

VCCIO is supposed to be 0.5v lower than your DRAM voltage (think I posted it in this thread a page or 2 back or another thread)!

DRAM @ 1.6v would have VCCIO @ 1.10v.

You will see Asus turns the fonts yellow to warn 1 notch above DRAM @ 1.65v and therefore VCCIO @ 1.15v!

I picked up a Costa Rica with batch number 3114C461, but it seems to be a crap. It takes 1.38v for 4.5ghz and it fails at 4.6ghz even with 1.45v.

My L139B137 will do 4.5GHz at around 1.36v anything above won't clock at all no matter what voltage, going to try a different motherboard see if I can do any better.

My other two 2500K's
