"I just wanted to oc it so I could play some games without lagg"

The main problem with the 3000+ Sempron is it only has 128k L2 cache. There's nothing you can do about it & overclocking can't make up for it. And if you don't have a decent gaming video card, it won't matter how much you overclock the CPU. So before starting the whole "how to overclock" explanation, how about telling us which video card you currently have?

"Nvidia GeForce 7300 SE"

As I suspected, your video card is an outdated, low end piece of crap. It was released about 6 yrs ago as an entry level card. It was considered an "upgrade" from onboard graphics but it's not a gaming card & was never meant to be. Overclocking the CPU isn't going to help, you need to upgrade the graphics. You don't necessarily need to spend a lot, just about anything will be an upgrade over what you have.

If you're willing to do the upgrade, let us know how much you can spend, which country you're from & whether you can buy online. One of us should be able to hook you up with a "best bang for your buck" gaming card. Otherwise, stick to games that are about 10 yrs old & your system will perform like a champ! lol

I'm sure it doesn't play those games very well. You can try overclocking the CPU - it should run stably at 2.25GHz - but as I said, it's not going to make up for lack of L2 cache & a weak video card.

EPOX went out of business several years ago so digging up the manual or any other info about your board is going to be a bit of a problem. Here's the specs:

I can only give you some generic overclock settings to try:

CPU frequency = 250MHz
CPU multiplier = 9x
HT multiplier = 3x (or 600MHz)
Memory frequency = 166MHz (or 333MHz)
PCIe bus = 100MHz
PCI bus = 33MHz
Spread Spectrum = disabled
Cool 'n' Quiet = disabled

If you can pull it off, the above settings will run the CPU at 2.25GHz, RAM at approx 204MHz (DDR408), HT bus at 750MHz. You may have to increase the CPU voltage to stabilize the overclock. If the system becomes unbootable, use the ClearCMOS jumper to reset the BIOS, then you can start over again.

i'll try that thx....but if I'm going to start a new gaming pc from scratch could you give me specs that would only take me a few bucks?...because i'm still just a student :)....and I want to upgrade this low-end crap pc.....I dont want my mom to pay for them because she aint using the pc.....I'm willing to spend maybe about 100-250 USD o_O....but if you could tell me how much is a cheapest gaming pc is then maybe u could tell it ^_^ thanks again!

A complete new build from scratch will cost at least $500. Adding a better CPU & video card to what you have will cost less than $75.

This A64 3000+ (2.0GHz) based on the Venice core will easily do 2.5GHz, plus it has 512k L2 cache compared to 128k for your Sempron:

And here's a cheap but decent gaming card, the Radeon HD 4650:
