I have 4x2 sticks of Corsair Dominator DDR2 1066Mhz on a MOBO Asus P5Q with a 1000w PSU.
This is the model of the memories: CMD4GX2M2A1066C5
This is the MOBO: (asus site can´t find it´s own product!) other site. The mobo supports memory with 1200Mhz on DDR2.
The problem is that I can´t get the memories run less them 5-6-6-18-3-52-6-3 on 1066Mhz. If I change any of those the system won´t post.
The best I could get was these timings with manual settings on:
CPU PLL Voltage: 1.52
FSB Termination Voltage: 1.24
DRAM Voltage: 2.10
NB Voltage: 1.12
SB Voltage: 1.10

Talking to corsair assistance through the site, I received this answer:
Please update the BIOS to the latest and use the followings:
DDR voltage: 2.1v
Memory Frequency: DDR2 1066
tCL: 5
tRCD: 5
tRP: 5
tRAS: 15
If the problem remains, then please try setting the memory frequency to DDR2 800 or even DDR2 667. There will be a lot more stresses on the memory controller on the system when all
memory slots are filled; to compensate for these stresses, memory controller will need to run these modules at a slower speed. The best analogy is car performance; the more
passengers you have, the slower the car goes. You will have to balance between performance and capacity when comes to adding more RAM to the system.

I can´t get them running at these timings they said.
How far can I go with all this ram on my mobo and how can I do it?

Thanks!!!!
