I have the Zalman 9500 LED. Also using 2GB Corsair PC2-6400 & Asus P5W DH Deluxe.
This was with the older bios (14-something). I haven't tested it with the newest bios 1707. However, I noticed a definite improvement in boot speed with the newest bios. The P5W DH is also very Linux friendly with everything being picked up but the wireless card.
