Just put together my system yesterday.
I'm using BIOS 803, a Q6600 (L745A) and 2x1Gb Corsair Twinx 6400 C5 Rev. 5.1
It was very easy to boot at high fsb, got into Windows @ 510 very easily. Also had no problems with my RAID, just "ported" my previous P35 instalation to the P5Q-Dlx.
But I'm having a hard time setting my RAMs on anything diferent than 1:1 with 450 fsb.
I used to run this kit on MSI P35 with the below setings @2,2V set on BIOS.

I tried the 2 lower RAM dividers just above 1:1 (1080 and 1130 I think), left everything on auto besides this setings:
CAS# Latency: 5
DRAM RAS# to CAS# Delay: 5
DRAM RAS# Precharge: 5
DRAM RAS# Activate to Precharge: 15
Row Refresh Cycle Time: 55
DRAM Voltage: 2.12 (tried 2,14 also)
Any advice?
