Its a false alarm, the cpu is dead, M4E is alive but I tested another 2600K on the M4E and it locks up at 4300 at any volts, so I tried it on another mobo with air cooling, it went a little higher oddly but locks at 4500, what the hell is this? Faulty cpu? Worst ever 2600K for overclocking? Or is something else at play here?

Any help would be great.
