Think it's dead

I think my 2500k cpu is dead the fans spin up and the led's on the mobo light but there are no beeps from the internal speaker and no output from a discrete vga card or the integrated gpu. Have tried removing the cmos battery and moving the clear cmos jumper for 30 min. Also tried with just one stick of ram and all drives unplugged.

Before it refused to boot I'd been trying to overclock it a bit more and lost my temper with it, whacked the multiplier up to 51 and vcore to 1.6v in the bios, switched on and dead as a dodo :(
 
An Asus P8Z68-V Pro I've taken the cpu out and can't see any pads which look discoloured, I've got a spare MSI board I can try the ram and cpu in
 
Got fed up of it seemingly hitting a wall at 4.4 GHz so lost my temper and decided it would clock higher or I'd kill it in the process, which is whats happened. Only decision now is do I get another 2500k or just a plain 2500 and settle for 3.7 GHz max.
 
Yes I'd increased the vcore in small increments in the past, it's how I'd gotten it to 4.4GHz. Can't see any physical damage to the chip the contact pads don't look burned or anything. Just wondering if I RMA it and OcUK accept it how long it will take to get the replacment.
 
bedazzled, have you tried the CPU in your MSI motherboard, which board is it?

I could probally help you get the 2500K CPU to 4.8GHz if it still works and 4.6GHz on Auto Volts using power saving features if it's a similar motherboard to mine.

Tried it in the MSI board with some spare sticks of RAM and it won't post not even a beep. Probably can't rma it as I got it from another e-tailer and their website states everything must be returned in it's original packaging, it was a retail cpu and I don't have the intel box anymore.
 
I've got a new 2500k retail cpu being delivered tomorrow which I'll run at stock speed, I'll try to rma the dead one and if successful I can try to sell the replacment cpu on the bay
 
I take it before taking a leap into spending another £150 on a chip you've whittled it down to it being the chip thats gone? Like removing everything else, running on stick of ram, trying various components in another machine if possible?

Worst case is you buy another chip to find you have also wiped out the motherboard and memory.

Installed the new cpu and the mobo and RAM are ok. Got the cpu running at stock speed not worth trying to clock it higher.
