need specs
Welcome to the forums!
Need your specs to help you out...
I unlocked my athlon t-bird 1000 using windshield defogger and turned up the FSB a little. Check out the guides and CPU database on the front page for a lot of usefull information.
General help: You'll need some benchmarking progams and decent cooling for a successful overclock. I recommend SiSfot Sandra and Motherboard Monitor 5 to help you get started. You'll need to look in your bios to see if you can change the front side bus, vcore, & cpu clock multiplyer. I recommend you start by figuring out what hardware you've got, reading the guides here, and browsing through the posts for a while to get a good understanding of overclocking techniques and dangers.
Keep posting with your questions and ppl here will help you out a lot!
