I'm new in the world of PC "hotrodding" I am just now studying for my A+ exam, so...can someone tell me how I would go about overclocking a Athlon 64 x2 4800+ 2.2 CPU? If it helps me understand you can tell me as though I was an idiot! Sidenote: I don't want to overclock like crazy. I want to use the OEM cooling systemand power supply. I just want to give the ol' CPU a nudge
Man I really don't feel like explaining that today . Anyway I guess I'll give ya some brief tips. Your CPU clock speed is determined by your front side bus (FSB) multiplied by your multiplier. In this case you have a default FSB of 200MHz and a multiplier of 11. No, don't get confused by marketing as to what your FSB is, on an X2 it's 200. Some vendors offer easy overclocking tools for their motherboards such as "Easytune" and so on. If you have a utility like this on your MB CD then you should use it since it's probably safer if you don't know what you're doing.
Now you're going to have to enter your BIOS so that you can increase your FSB. Consult your board documentation for how to adjust it. Start off with just a few MHz. Keep in mind that you should also lower the speed of your RAM. I'm assuming you have an AM2 board. To get DDR2 RAM speeds you're CPU divides it's clock speed by an integer divider, so at 2.2 GHz it will use a divider of 6 to get the clock speed of 366 (or 766 effective for DDR2). That means you can go 44MHz on the FSB before you have to start lowing the speed of your RAM or your timings, since I'm guessing you don't have overclocking RAM. Download Prim95 and run it a couple of times everytime you increase the FSB. If it gets errors or crashes, go back down to the last setting.
If you have a prebuilt system, such as an HP or a Dell, then you'll have to flash the BIOS to a custom BIOS to get those options. In that case you're on your own
