Help! Overclocking LGA 775... Frustrating!

Hey all,

I'm trying to bring up my FSB to 400 so I can hit 3.6Ghz with the Q6600's 9x multiplier. I'm using the 2 x 4gb DDR3 G.Skill Ripjaws X kit, shown here;

They are rated at 1333Mhz, but obviously I'm pushing for 1600, but I don't understand a few things, such as the 'DRAM Timing Selectable', i.e. memory multiplier. I don't know what to set it to, or what it's for.

This is what I see in the BIOS options of my GA-P35C-DS3R, where the first number appears to be some sort of default, followed by an entry I can change;

DRAM Timing Selectable: 1066 _____

Standard Timing Control:

CAS Latency 7 _____
DRAM RAS# to CAS# Relay 7 _____
DRAM RAS# Recharge 7 _____
Precharge Delay (tRAS) 20 _____

Advanced Timing Control:

ACT to ACT Delay (tRRD) 4 _____
Rank Write to Read Delay 4 _____
Write to Recharge Delay 8 _____
Refresh to ACT Delay 86 _____
Read to Precharge Delay 4 _____
Static tRead Value 5 _____
Static tRead Phase Adjust 0 _____

System Voltage Optimised:
(Note: these are listed as either 'normal' or +0.1V, +0.2V, etc).
DDR2/DDR3 Overvoltage Control:
PCI-E Overvoltage Control:
FSB Overvoltage Control:
G(MCH) Overvoltage Control:
CPU Voltage Control:
Normal CPU Vcore: 1.26250V

I've used 3.2Ghz for a while (356 x 9), but since mucking around and trying to get it higher, I've forgotten the settings and have had to revert to the default 2.4.

My notes suggest that in the past, I managed 400 x 7 and 420 x 6, but now I can't even managed 356 x 7. I must be doing something different with the multiplier, timings, etc.

HELP please... it's getting really frustrating considering I've done it in the past!
