Hi, need you guys to help me tweak my motherboard. There are a lot of features I don't know whether to enable or disable.

Considering my system is this:

Motherboard: Foxconn P35A
CPU: Intel Q6600 GO stepping (OC to 3.15 GHZ)
RAM: Kingston HyperX (4 x 1GB) DDR2 800 PC2 6400, 4-4-4-12, 1.95V, KHX6400D2LLK2/2G
Graphics Card: 8800 GT 512 MB

Please tell me the values I should use on these BIOS settings:

FOX CENTRAL CONTROL UNIT:

Spread Spectrum
Memory remap Feature
Memory Hole
Super Clock Free
Intel Speedstep Tech
C1E Support
Hardware Prefetcher
Ajust Cache Line Prefetch
Max CPUID Value Limit
Intel Virtualization Tech
CPU TM Function
Execute Disable Bit Cap
Multi core Processing

PCI/PNP RESOURCE MANAGEMENT:

Plug and play O/S
PCI Latency Timer
Allocate IRQ to PCI VGA
Palette Snooping
PCI IDE BusMaster

BOOT CONFIG FEATURES:

Interrupt 19 Capture

As I told you before, most of the values are enable/disable or yes/no options, please advice on each one and if you like you could tell me why.

Thanks in advance

If it's working fine, leave all the values at default; most are power saving features that can you can only benefit from. Spread Spectrum might need to be disabled for stability when OCing.. but that's all I can really say.
