Hi all,
I've got a NF4 Sli Ultra-DR Expert mobo.

I've just bought a pair of Corsair 1GB TwinX DDR, PC3200 (400), 184 Pin, Non-ECC Unbuffered , CAS 2-3-3-6 RAM sticks to put into it - to make a total of 4.

With any combination of 2 (in the orange slots), the mobo fires up fine. If I add the other two, the mobo seems to freeze on 3 LEDs.

I tried dropping the RAM to 2T as opposed to auto, and dropped the multiplier to 166, but I still get nothing. I even tried upping the RAM volts a little bit.

Anyone got any ideas?

Tom
