Another Overclock Question

Specs: Windows XP, 1000FSB/2.2ghz Phenom 9500/Kingston HyperX 4gb DDR2
First off i've never overclocked a PC before so not 100% for sure how to go about doing it. I would like to overclock my CPU It's currently rated at 2.2ghz and I would like to get around 3.2ghz. Reason being I would like to play my old console games on my PC with a emulator I downloaded, but I was told you really need 3.2 - 4ghz from your CPU to be able to run these games smoothly my PC currently will run them but its just a tad bit laggy. Anyhelp on this or information you techs can provide would be helpful. My current temperture is 34degrees I have 2 fans and a air vent, what do you think the max CPU speed I could get from my CPU without harming anything?

Also what is your take on 3rd party software that allows over clocking straight from the desktop.

GPU 9800GTX+ 512MB Asus
M2A-VM M/B Asus
CPU Phenom 9500 2.2 AMD
Kingston HyperX 4gb Ram DDR2 800 (PC2 6400)
Windows XP
650Wat PSU

Going from 2.2GHz to 3.2GHz with a Phenom 9500 is unrealistic. Besides, you've got the wrong board for it & the wrong RAM. You *may* be able to get it up to about 2.75GHz with the right combination of settings.

I just figured that out... oh well. The most I am able to get out of it is 2.4ghz without blue screening, kinda sad but atleast I know to think all things through with the next PC I buy.

If you're only getting 2.4GHz, you're not overclocking properly. Here's what you gotta do:

- disable Cool 'n' Quiet
- lower the RAM speed to DDR2-667
- lower the LDT bus frequency to 800MHz
- disable Spread Spectrum
- increase CPU voltage to 1.30v
- increase CPU frequency 5-10MHz at a time. Try to get it up to 255MHz.

If you can pull it off, the CPU will run at approx 2.8GHz, the RAM will be back up to DDR2-800 speed, & the HT bus will be at 1020MHz.

Well I tried it your way and did each step you had said and I got 2.7ghz out of my system but then it started acting werid and kicked it selfs off when I hit reboot button it would not boot up the PSU wouldn't make a sound... It blew the PSU which I just bought 2 weeks ago, I have my old 400wat running in it for now hopefuly they will send me a new one >:) anyhow I am done with overclocking untill I learn more about it and I get a PC thats more tuned to overclocking, or find a cheapo I can mess around on.

One thing I neglected to state in response # 3 is that you *may* have to increase the CPU voltage above 1.30v to stabilize the system. Some CPUs will happily overclock at 1.30v...some may require, 1.325v, 1.35v, 1.375v, 1.40v, etc. Overclocking isn't an exact science, it's trial & error.

If the system simply became unbootable, it's because you over-overclocked without increasing the CPU voltage enough. But if you blew the PSU, it's not because you overclocked, it's because you bought a garbage PSU. A decent name brand unit costs at least $50 & has to be speced out correctly. The best units have a single +12v rail with at least 30A. Here's an example:

Actually, it has 38A on the +12v rail. You probably paid $75-100 for it? Lucky for you it has a lifetime warranty. Get it replaced, sell it & buy something decent.
