Specs: Microsoft Windows Vista Ultimate 64, intel core 2 quad Q9450; 2.66GHz / 8192 MB ddr3
Hi everybody! I have an MSI motherboard (x48c platinum with ddr2 & ddr3). I have the latest version of firmware on the board (7.4) I believe. I have 8gb ddr3 xms installed (pc3-12800) from corsair (cmx8gx3m4a1600c9 XMS3 8GB PC3-12800). I have an quad core q9450 with the corsair h50 liquid cooler. I have Windows vista ultimate 64 bit installed on a WD caviar black (500GB). Finally, I have the EVGA GTX 260 super-clocked version. Mainly, that's my gaming computer. cuz I got another one that I do other stuff on. Would someone please tell me the best way I can get that computer over-clocked and I have tried and failed with the specific configuration to set it on . Please help me! I've spend a lot on that to enjoy my games.... I really count on your help....

Wouldnt really be worth overclocking it would be a waste of money if everything breaks, im sure its fast enough as it is.

Nothing will break if you know what you're doing. The worst that can happen is the system will become unstable or unbootable & if that happens, all you need to do is load the BIOS defaults (or use the clear CMOS jumper) & start over.

The main thing to remember is to maintain the proper CPU:DRAM frequency ratio, which in your case should be 1:2. If you're currently running both the CPU & RAM at their default bus speeds, the ratio is 5:12.

All you need to do is increase the CPU frequency to 400MHz (1600MHz FSB) & configure the RAM settings so that the frequency stays at 800MHz (1600MHz DDR). The PCIe frequency should be locked at 100MHz, the PCI locked at 33.33MHz & all Spread Spectrum options (if there are any) should be disabled. If you can pull it off, the CPU will run at 3.2GHz with the ratio at the desired 1:2.

I prefer ratio 1:1(1600 FSB & 800 DDR) and if u decrease ram clock (800 DDR) u can gain perfomance by decreasing ram timings(u can check timings with cpu-z). U need to increase cpu voltage(safe voltage range for Q9450 is 0.85 - 1.3625v if u exceed vcore u will hurt the processor).

Try the settings above again but with a small step up in the Vcore voltage. Go slowly here as you want the lowest stable voltage or you will run your CPU on the hot side. Repeat as needed and then test the stability while monitoring the temperatures.

You have to be a little bit crazy to keep you from going insane.
