erm...do you mean you need to make it boot off the hard drive? Cos thats a simple case of changing the boot sequence in the bios...other than that it may look like I've missed the point altogether!

Have you tried it with a single stick?

It sounds like the memory is faulty and the motherboard is trying to recover the BIOS from a CD. I had the same problem with my Gigabyte P35-DS3P with some OcUK PC8500 I recieved at the w-end. It would boot ok with a single stick, but it kept trying to recover the BIOS with two sticks inserted.

Needless to say I RMA'ed the memory this morning. It's a pity because I currently have a pair of OcUK PC8500 that have been running perfectly for a couple of months.

That sound aboot right, but i have plugged the ocuk ram in the pc at work and it booted fine but only at pc4200 speed as thats all the pc at work supports, not tried a single stick or differant slots will try that, and if not RMA it

The single stick booted ok at PC6400 speeds in my system, but wouldn't run below 5-7-7-25 at the advertised PC8500 speeds, no matter what i set the voltage to. It also wouldn't run below 5-5-5-15 at PC6400, which would suggest that it didn't have a hope of running those timings at PC8500.

If you can get it to boot with a single stick, set the advertised settings of 1066mhz (PC8500) and 5-5-5-15 in BIOS with the memory voltage (vdimm) at 2.1 or 2.2v. If it then refuses to boot with both sticks at those settings then they'll have to be RMA'ed.
