I just got my new system up and running so I haven't a chance to play yet. I would be interested to hear what you are using to cool the CPU and how far you are able to push it. I believe with the H50 I can get my goal of 3.6 - 3.8 GHz without raising the temperature much. Time will tell.
Easily. Most people around here use a high end heatsink, the H50, or water cooling. For example, I have a TRUE for my LAN rig and a Prolimatech Megahelms for my main computer. Both do a tremendous job.
Would raising the multi in conjunction with the BCLK increase performance more than raising the multi alone? I ask because I know that other frequencies are tied to the BCLK and thought that raising them would help along with the faster CPU.
Of course. However, the point of having an unlocked multiplier is to
avoid raising the BLCK or the FSB of a chip higher than you normally would need to. I would suggest raising your multiplier first until you hit instability. Reduce the multi by 1x and then raise the BLCK little by little until you're at your goal. Raising the other frequencies, while necessary, does little for recognizable performance. The CPU/GPU/SSD (hard drive) are the parts where you see the biggest performance gains.
