Shuttle SP35P2 Bios and memory configuration

The Shuttle SP35P2 Bios and memory configuration isn't exactly easy if you want to use your memory at 1066Mhz. Mainly because the memory sticks are usually only tested to the 1600 speed, but built to slower 800Mhz specification at which the motherboard will recognise it!

Here is the description on my Kingston Hyper X memory:

Kingston’s KHX8500D2K2/4G is a kit of two 256M x 64-bit 
2GB (2048MB) DDR2-1066 CL5 SDRAM (Synchronous 
DRAM) memory modules, based on sixteen 128M x 8-bit 
DDR2 FBGA components per module. Total kit capacity is 
4GB (4096MB). Each module pair has been tested to run at 
DDR2-1066MHz at a latency timing of 5-5-5-15 at 2.2V. The 
SPD is programmed to JEDEC standard latency 800Mhz 
timing of 5-5-5-18 at 1.8V. Each 240-pin DIMM uses gold 
contact fingers and requires +1.8V. The electrical and mechanical specifications are as follows  

So in the shuttle bios you need to up the voltage to 2.2v and set the values manually. I found the ratio to use was a 2:1 FSB with my Core 2 Duo Quad Q6700 (This will vary depending on your CPU and Rated FSB)
