Hi guys, I'm new to OC-ing so I have a few questions that hopefully you guys can help me with. I'm using a Q9550 processor and I intend to OC the FSB from stock to 400MHz. What I understand from doing a bit of reading on the net is that the Q9550 can handle that quite easily, is that right?

Also, if I OC the FSB to 400Mhz but reduce the multiplier to 7.5 to get to 3000MHz, does that reduce the stress and heat on the processor?

I'm doing this because I have 2 x 2GB OCZ PC2 8000 Platinum which I am trying to use at it's rated frequency of 1000MHz but the only way to do that is to OC the FSB of the processor since it doesn't have EPP. The motherboard I'm using is Gigabyte EP45-UD3L.

I've so far tried bumping the FSB to 400MHz and leaving the multiplier at 8.5 i.e. 3.40GHz, which puts my RAM at 960MHz. My PC boots fine and works but I've noticed that the fan runs at a higher speed when I play blu-ray videos (I guess that puts the processor close to full load). If I don't OC and have my processor at 2.83GHz stock speed, the fan doesn't run as fast while playing the same blu-ray video.

As you might guess, the fan noise is a little annoying, which is why I'm wondering whether reducing the multiplier to get 3.00GHz would help reduce the heat and hopefully mean the fan doesn't go full speed.

I'm pretty sure because when I am not OC-ing and watching the same blu-ray show, the fan doesn't speed up. If I do OC, then after awhile I will hear the fan speed up.
