Overclocking Core 2 Processors

[HardwareExtreme]

Hello everyone,
I was wondering if anyone could give some tips for overclocking Core 2 CPUs. Yes, I know they are old, but I wanted to try overclocking for something fun to do.
So, this is what I have to work with:
XFX nVidia 680i LT Mobo
2 x 1gb DDR2 (Hynix generic ram, I have nVidia SLI ram available as well) @ 800 mHz
nVidia GT 210 1gb (I may use a 9500gt or Quadro FX 1800)
120gb IDE (ATA133) with Windows 7 Pro x64
Heavy(er) Intel Cooler

These are the processors I want to try:
C2D:
e8500 (SLB9K)
e6550 (SLA9X)
C2Q:
q6600
PD:
820 (SL8CP)

However, does anyone have any tips for this? I have overclocked before using SetFSB, but that was as far as I have ever gone (Hit 3.00gHz on that Q6600 in a Optiplex 960, somewhere on the forums)

None of those are unlocked, so you have to max out the multiplier and increase the FSB to get higher clockspeeds. Also, since this is 775, the memory controller is in the northbridge, so the FSB:RAM ratio is important too. You should be aiming for 1:1 which means 400Mhz FSB and 800Mhz RAM, since it is DDR2. It will work with other ratios, but the performance may be worse if these clocks are out of sync eg. 400Mhz FSB and 900Mhz RAM.

And make sure you cool the NB properly, as you may need to give it some extra voltage for higher FSBs.

Let me know how you're getting on.
