The title says it all. Don't I have to do soemthing to my bios before I can overclock? Is there some place to get custom bios or something?
 
Solution
Your BIOS will most likely have every option you would need completely disabled and unavailable. There would be no way to change the BIOS on the system with a custom.

Since I doubt you can change anything, like CPU voltage, RAM speed/timings, and the FSB in the bios, there's only the software option. You can probably find software that will allow you to change the front side bus, but this will speed up everything, the CPU and the RAM. Since you can't increase the voltage to feed more power to the CPU, and you would be running the memory out of spec, this will undoubtedly cause stability issues, crashing, and overheating. You might be able to get a tiny little bump in speed, but we're talking a single digit percentile increase that...

'clockgen' is the type of software that might work. For the sake of completeness, I dug through my backups, and found it, back from 2007 or so. Here's a link. Fair warning, this will allow you to overclock, and completely destroy your computer. The overclock settings can be setup to apply at startup, if it ever starts up again. I don't doubt your competency, but merely stressing the most likely outcome if the experiments were to get out of control =)

Overclocking needs two things to happen: a PC and an enthusiast. The best thing that can happen in this case is the achievement of a stable yet high overclock. As it's just not a job for the average user, overclocking must be accompanied by rigorous hardware temperature monitoring and solid in-depth knowledge regarding all the aspects of your computer component tagged for this particular operation.

Once you are all prepped-up for overclocking your system, you need the right tools for the job according to the system component you want to boost its performance. ClockGen is not yet another overclocking utility. It uses the PLL (phase lock loop) of your system to increase or decrease the overall clock including CPU (Central Processing Unit), FSB (Front Side Bus), RAM (Random Access Memory), PCIE (PCI Express) and PCI (Peripheral Component Interconnect).

Determining your PLL is the first thing you need to do. You can just search the Internet for it by entering your motherboard's manufacturer and model as well as the term `PLL`. If this doesn't help, then you have to guess it by trying each one of the available options within the Clock Generator Setup section of the PLL Setup window and then click on the `Read Clocks` button to check whether the readings are accurate or not.

In case they reflect your system's configuration, then you may have found the correct PLL and you may now step forward and actually change the clock of your system within the `PLL Control` window. The recommendation is that you take this step-by-step by slightly increasing your values and apply the selection every time you do it in order to check if the system crashes or not.

You can verify your working overclock by running various benchmarks or stress tests in order to make sure that the achieved values result in a stable system. One more time, you have to strictly monitor the temperatures inside your PC just so you don't end up with all sorts of problems from burnt CPU to overall damage of your hardware and warranty loss that costs you the entire system.

Putting the risks aside, ClockGen is a very witty piece of software that, although asks for advanced knowledge, truly puts the entire motherboard alongside its connected components to a rather scientific overclock process based on the PLL of your system. Due to its nature, ClockGen does not address to beginners or users that don't want to take chances but to overclocking enthusiasts. In fact, this tool is exclusively created for this type of users.
 
Hi. As the first poster stated, beiong a Prebuilt computer, the things you need are locked. If you know what BiOS you have, you can go to www.bios-mods.com and see if they have an unlocked BiOS image posted. I would be surprised if they did though.
 
I took a peak on the site. I found one case where a guy with a 545 bricked his PC with a modified bios someone on the forums provided. There's no indication if it was a bad mod or user error though. Either way, scary stuffs ;-)

Try the clockgen software if you really want to fool around a bit, if there's a little bit of success there, then a modified bios, coupled with much better cooling could go a long way.
 


Most likely user error. I have spent a lot of time over there and those guys are good. I was looking for one for my Gateway FX6800-01e. I got one and made up the flashdrive, but got side tracked with other things and before I got back to it, said the heack with it and did a build. I diod try afterwards, but couldn't get the flash to execute for some reason. probably something I did making up the flashdrive.

I tricked clock gen, with that softpedia download link but my pll is not listed as a supported one. i checked around also and found my pll was not in the rather short list of different software for changing fbs. i dont think im going to mess with it....actually im going to take a look at the bios mod website...
