I have got my E8400 up to 3.6ghz really easily by increasing the voltage to 1.3 seting the fsb to 400 and leaving the memory at 800mhz in the bios option. This put me to 3.6ghz but however upon going back into bios my memory was running at 961mhz on a ration of 5:6, so i had the option to set it back to 800mhz so i did which put me on a ratioof 1:1 which in my opinion felt a little faster.

My main use of my pc is gaming, so what is better

961mhz at 5:6 ratio
800mhz at 1:1 ratio..

Both of these are at 3.6ghz..So this may change as i want to try and get my E8400 to 4ghz..

How would i do this? What voltage and fsb should i be looking at? and can i do this with a 1:1 ratio?

specs are

Intel Core 2 Duo E8400 LGA775 'Wolfdale' 3.00GHz (1333FSB)
Corsair 2GB DDR2 XMS2 DHX PC2-6400C4DHX TwinX (2x1GB)
150GB Western Digital 10000RPM 16MB Cache Raptor X
Asus Maximus Formula Intel X38 (Socket 775) PCI-Express DDR2
Coolermaster Real Power 700w Modular
Arctic Cooling Freezer 7 Pro CPU Cooler (Socket 775)

Thanks for your help
 
for the memory ratio question i would set it at 800 then push the fsb for 4ghz

when i had my 8400 i set the core to 1.3v the nb a bump (was running 4dimms) and think that was about it to be honest.
 
Since the lowest divider you can get is 1:1, you'll be limited by your memory in this case. Set divider at 1:1 and start pushing your fsb up until you lose stability, at which point you'll need to add more vcore (or potentially up your ram/NB volts if that has no effect). Eventually your RAM will hit a limit though, and that'll be your max OC. 4GHz is pretty easy to acheive with these chips, you shouldn't need more than 1.3-1.33 to make it there. After that, you start needing a big jump in volts to make it to 4.5GHz
 
got it to 4ghz easy on a 1:1 divider with memory running at 890mhz with 445 fsb :D

everything seems stable so far..surprised how easy this was and that ive never done it before :o
