Corsair XMS2 PC-6400 issues

[Dimebag]

Hi

I've recently upgraded to an asus P5W Deluxe board with an intel conroe E6600 in it.

The ram is corsair XMS2 PC-6400 ram, rated at CL4.
When I set the chip to its defaults, i.e. no overclocking and then force the ram to 800mhz, the machine falls over on boot.
This is whilst keeping the ram on AUTO SPD settings, so its not even running anywhere near the aggressive timings that the box/ram promises.

Is this indicative of faulty ram?
I've bought a new PSU from hiper that runs at 480W and I've done the maths so I doubt its a power issue.
One thing I have thought of though, could the board be supplying less voltage than the dimms need because of the AUTO setting for that feature?
Is it worth me finding out what voltage the ram is meant to run at and just plain setting it at that value?

Cheers

Paul

Aye i think mine is rated to the same 2.1V
The board is the asus P5W DH Deluxe one.

I've just been told by a mate that its possible that the AUTO function of the board I have will limit the voltage to the lowest value. If that is the case then I wouldnt be surprised if its under supplying the memory and causing the machine to shutdown on windows boot.

Seems a little retarded to me that ram that is specced to run at certain voltages and timings gets serverely chopped down by "defaults" encoded into the same chips.
