I want to over clock my system, I have just added a new cooler and PSU and now just need to work out how to overclock my cpu, I have gone into the bios and think my multiplier is x9 but how do I change the speed to get a higher speed and will I need to increase my voltage?

Post your specs...motherboard, CPU, RAM, video, power supply. The more details the better.

Msi board but don't have the number but 3GB ram, 750 watt PSU 6600@2.40ghz Intel core 2 it has its own dynamic clocker but just didn't do anything oh yes and graphics card nvidea 8600GT may uograde that but want to see what I can get with a clocking first

Like I said, "the more details the better"...you didn't come thru. We need to know the exact make/model of the motherboard. And saying 3GB RAM is useless if you don't tell us whether it's DDR2-533, DDR2-667, DDR2-800, etc & whether it's 3 x 1GB or 2 x 1GB + 2 x 512MB. Same goes for the PSU...750W is meaningless. We need to know the make/model & amperage specs. If you don't provide the necessary info, you'll never get the answers you need.

Wow you lot are good, right I will get it all and post it later, I am disabled so got a mate to move the pc and I will need to wait for a mate to come over after work tonight and get all the details for you, thanks for taking the time to help, I will get everything later and re post, Thanks, Chris
