On the overclock I had some success yesterday:
Ran the pc using an option within the bios which clocks the system by 20%, this took my cpu up to 2.9Ghz. I had a browse around on the web to find out what others had been doing and tweaked a few voltages and managed to boot @ 3.6Ghz (unlinked the memory and FS
then manually inputted 1066Mhz for my RAM and 1600Mhz for the FSB. The FSB is quad pumped so you have to divide that figire by 4 to get the true FSB....400Mhz. As I say, the PC booted and got me all the way to the black windows screen (you know the one with the windows 'flag' on it. The image of this screen was a little faded...then the system restarted before I was able to get into the desktop...weird. Tried upping the cpu to 1.5v still no joy....the Northbridge was running at 1.45v (stock is 1.3v) and is not very well cooled so didn't want to pump more juice through that...well not until I get some better cooling on that!! What d'ya think would cause that?? Maybe I should try running a 5:4 memory divider?
After trying to get into desktop @ 3.6Ghz I gave up (need to read around a bit more) I dropped the FSB from 1600Mhz (400) down to 1550Mhz (387.5Mhz) which gave me a CPU speed of 3.48Ghz. I got back into windows and run a benchmark 3DMark06....was obviously expecting good things....
But...was shocked to find my score @3.48 was lower than the score I achieved with the cpu @2.9Ghz....why d'ya think that happened?
