I found another way to overclock GP32's very easily. You just need to have your GP exposed to a high amount of radiation.
1. Get to the nearest nuclear power plant and ask, if you could borrow some of those nifty little green sticks. They usualy got plenty, so they'll be happy to give some away for free. You then have to put this stick inside your GP32. This has many advantages: your GP32 will now be able to clock to 16765 Terrahertz. And the best thing: you got a BLU! butt all colors seem to be a little bit more green than before. If your local Nuclear plant doesn't want to give you some sticks, and your local Uranium dealer is out of uranium, you may aswell ask your local Nuclear power plant, if you could build yourself a radiation gun, and just borrow one of those sticks for a few minutes. Blueprints are available on the internet, you just have to google. However, the BLU effect won't appear.
2. If you don't have ANY access to uranium (Yes, there are some countries that have banned it from legal market because of it's green color), you can just use a common Microwave oven. There is no BLU effect here either, but your GP32 will go as fast as 500 Terrahertz (yes, it's a bit slower, Uranium is more effective).
so this is it. And remember, If you put uranium into your GP32: replace it every 2255000000 years, as it will have lost half of it's radiation.
