I'm looking for a good guide on how to overclock the AMD Athlon 64 x2 6000+ (windsor). Lately I've been using ASRock OC Tuner, and I can get the bus to 210mhz (which goes to 3.14ghz at the stablest). I've seen others get it to 3.2 or 3.3 ghz (on air) by setting different voltages, HT, multiplier, fsb, vcore, and other things that I'm unfamiliar with finding in the bios (things like the north and south bridge voltages, vdda, ht link voltage, etc.. can't find them). I just need someone to help me or show me a guide clear enough for a kitty to understand so I'll know if getting a more expensive cpu is necessary. My need for having more cpu speed is to play gta4 a bit smoother. I know it's bottle-necking for sure.

Why are you posting about overclocking in the gaming forum? Try the overclocking forum. But just to set you on the right path, you need to overclock manually, not thru some "one-click" method. You also have to understand that the 6000+ is pretty close to being maxed out in it's default state...an increase of 200MHz (less than 7% overclock) isn't gonna gain you much performance & probably wouldn't even be noticable. It would help to know the make/model of your board, also the amount/speed of your RAM, but if you're experiencing problems with a game as relatively lightweight as GTA 4, my guess is you have a weak video card.

Wasn't expecting a "one-click" method. Just needed to know where to change all the aspects in my bios. I should've been clearer about it. Sorry. Didn't know where I was posting. Thanks for an answer though. It was noticeable when overclocked to 3.14GHz. Video card is an HD 4670 IceQ 512mb. RAM is 2 x 1gb ddr2. How is GTA 4 lightweight?

Maybe "lightweight" wasn't the best term. What I meant was the hardware requirements aren't extremely high - your system far exceeds the minimum required. Can't help you with overclocking if you don't answer the questions: - make/model of motherboard? - speed of RAM? DDR2 is not the speed, it's the type. Is it DDR2-667, DDR2-800, DDR2-1066, etc?

Okay. I've gotten it stable at 3.28ghz. Wont go much higher unless I find a better fan. - ASRock A790GXH/128M - DDR2-533 Is a better fan worth buying over a Phenom II x4 945?

Well you will need better ram as well if you want a Phenom processor. DDR2 533 isn't going to cut it by any means, because it will put a big bottleneck on Phenom processors. The minium amount of ram speed you should be running a Phenom processor is DDR2 800, but for optimal performance you need have the ram running at DDR2 1066. So with any Phenom you get, keep in mind that you will also need much faster ram then what you have now. Iron Sharpens Iron.

Alright. What power supply do you recommend? My 350W probably wont be enough for DDR2 1066.
