I've recently starting overclocking my CPU. It's an E6300 sitting with with 2xGB Elixir DDR2800mhz on an MSI 975x Platinum motherboard. The PSU is an Enermax Noisetaker 485w.

Everything is totally and completely stable (Orthos, gaming, diagnostic tools, etc) at FSB 381mhz frequency with ram/fsb at 1:1 ratio. Processer's at 2.67ghz, memory's at 762mhz and the computer runs stable as I've said before. Ram voltage is 1.8v, CPU voltage is 1.15v, I haven't touched those yet.

But then, whenever I even try to go over FSB 381mhz, there is no video signal, and no beeps. I have to reset the BIOS settings by pushing a little button on the motherboard. So currently the computer is tiptop stable, fit as a fiddle etc etc on FSB 381mhz, but refuses to do anything at 382mhz and over. What could be the reason behind this? Would upping either voltage help?
 
I upped the vcore to 1.2, previous setting was on 'auto'. I haven't upped the FSB or anything yet, I just want to show you guys the CPU-Z information in case I've missed something major.



Anything out of the ordinary?
 
Unfortunately, I can't do it - my vcore is at 1.27 and the FSB is at 382 maximum. If either or both of those go up, my computer hangs on desktop after a few seconds. Just freezes completely. The temperate of the processer only hits 57 at the most though, which is puzzling. It's hardly going through fiery hell, so I have no idea why it won't go any further.

The highest volt I can touch without it crashing straight away is 1.27, which does 57 degrees under full load. I'm using CoreTemp as my temperature monitoring program.
 
It's an Arctic Freezer 7 Pro. I'll check out TAT. Thermal Analysis Tool isnt it?


Edit: TAT won't open for me. Even if I turn off 'force unsigned drivers on' in the startup menus, TAT opens for about a split second then turns off.

The heatsink came with the thermal compound already applied. I didn't struggled to put it in, but I guess it's worth taking a look again.
 
That's a possibility, nothing on google about the MSI 975x Platinum being a particularly poor overclocker though.

Edit: It's just dawned on me that I haven't changed the CPU multiplyer yet :p

2nd Edit: Nuts, I can't seem to access the option to alter it.
