Default Can't overclock CPU since having 8800GTX!

With my 8800GTS I can change the CPU Host Control no problem. However since I have inserted my new 8800GTX, if I set the Host Control to Enabled, the computer will shut down and restart itself during the POST screen and the setting will be changed back to Disabled. This is reardless of the actual number I set it too, even default 266 etc or even lower numbers like 200 making the CPU frequency 1.8GHz.

Is this because the 8800GTX is draining too much power from my Antec NeoHE 550W? That's the only thing I can think of. The computer at default 2.4GHZ with Host Control disabled is fully stable though, so if it was a power supply thing you'd think other things would go wrong.

When I change from the GTX back to the GTS it is all fine again...

I've tried resetting the BIOS, still the same... also changing voltages and CPU Vcore has no effect.

Any suggestions?
