Ok cool.. Syrillian

Ok so i get this right this would be settings..
Unlinked ram and fsb
fsb = 1066
Ram manual set too 400mhz ( am i correct in saying that)

Then i just increase the fsb 3-5mhz at a time.

Am i correct in the above ?

For a rated FSB set to 1066, your RAM would be set to 266 (266[.5] x 4 = 1066)

Take a look at the picture that I posted. You will notice that my FSB is set to 440 (3.52GHz clock speed). My rated FSB is 1760 (4 x 440).

This means my RAM is running at a 1:1 ratio of 440 (880 effective).

There are a few methodologies that are followed when determining the highest OC that a system can take. Temperatures and VCore not withstanding (though vital), most people will OC the CPU and the RAM sepeartely to see what each of the elements can take, then tune from there.

Since you RAM is running under spec, you could leave the RAM at auto, and push the CPU (you have a 133MHz window to play with [400 - 266 = 133 +/-).

In the advanced Tab change the CPU Frequency setting at 5MHz increments, and re-boot. When the system fails to Boot, or becomes unstable start to up your VCore. The thresholds for Voltage and temps that I use as a rough guide for the top-end settings on my Allendale are:
  • VCore = 1.40 (after droop)
  • Temp = 55-60C (Load)
I generally do some stability testing every 20MHz or thereabouts (3DMark06, Games, Orthos, TAT, etc...)

So:
  • Leave RAM at Auto.
  • Raise CPU frequency by 5MHz
  • Stability test every @ 20MHz increase
  • Monitor temps (<55-60C) and be aware of the VCore (<1.40).

I would recommend that you download and use Intel's TAT (Thermal Analysis Tool) to monitor your temps
