Overclocking question

[imported_Mitchell]

So I'll post it here maybe someone has an answer for me

I just reciently did an upgrade to my computer. I am using the following components:

AMD FX-55
MSI Neo2 Platinum MB
OCZ EL Duel Channel Platinum Rev.2 (512x2) 2.2.2.5
I have the H20-120-64? (Rev.2) AMD® K8 (Athlon® 64 and Opteron®) CPU Liquid cooling kit - 120MM RADIATOR/FAN watercooling system.
eVga 6800ULTRA AGP

I read some articles here and some reviews about overclocking these components, but I am unable to achieve the speeds, or even close to, the speeds of the reviews here.

I can get the system to run at 200 FSB with a 15x multiplier, which gives me 3.01 speed. But if I lower the multiplier I am unable to get the system to run at a faster FSB, even if I encrease the voltages.

Anyone have tips on how I can achieve 3Ghz with a faster FSB, say 250 Mhz FSB and a 12x multiplier, stabily?

If I increase the FSB do I have to increase the memory latencies?

Thanks. I am probably missing something somewhere, could use someone to just point me in the right direction

For some pics of the cooling system. In case you were wanting to look into watercooling. Very easy system to install.

I am looking at the memory timings as the main issue why I can't get the FSB up faster while lowering the clock. If that is the case, is there a 'sweet spot' for the FSB, Memory timings and multiplier on this setup?

Edit:

I just read that I should also look into lowering the HT from x5 to x3 or so when increasing the FSB due to most processors not liking HT above 1050. I guess this could be another issue since I never lowered the HT speed at all when increasing the FSB.

I wonder where the cut off is where the benefiets of overclocking the FSB, while reducing stuff like the HT and memory latencies, no longer pays off.
