I overclocked my gbo

from the stock 4.194304 MHz to 49.860MHz this thing is ausome i will post pictures and a video soon. And you wont believe how simple it was all i did was remove the old crystal and replaced it with 2 wires the wires run to the outside of the case so i can use any crystal i want.

I hope you have like watercooling on it, or the processor is going to start on fire.

i havent ran it more than 10 seconds at a time so far
i am gona heat test i right now

all hte chips stayed cold for 1 minute i dont think its gonna overheat

here is a video of it in action

thats me in the video
the game i used was game&watch gallery it was the only one that would get past the nintendo screen
the background music is from my sister watching tv
do any of you guys think this was a waste of time? my parents shure do.

cool, but kinda stupid,and unorthadox, as the game would be to fast to play lawl

the whole point was to see how far i could push the gbo processer before it blewup/melted not toplay games a little faster if wou look at the video the grphics are so garbled at that speed you cant tell what is going on

Actually somebody pushed it way further (around 500Mhz I think) but he froze the board first and then used a huge fan while it was running.

well im gonna push mine to 1 gigahert
anyone know where i can get a crystal that fast?
sammy can you please provide a link?

You are going to need either a liquid nitrogen or liquid helium cooling system.

I'm pretty sure that Z80's dont generate any noticable amount of heat, like ARM cpu's. So you probably cant cause any damage. Then again the chip will have a maximum stable limit, varies from processor to processor. Thing is, you have prabably reached yours, since you said only one game boots past the nintendo screen. Also, cooling it isnt going to help much, if at all.

I overclocked my GBC from 8 mhz to 14, and its still playable. It would be cooler to find the maximum speed that games can run at.

You ARE aware that Liquid Nitrogen, Helium, and any other gas that's a liquid and cold is cooled by machines and such, right?(Well, you know what I mean). The only thing a Liquid Nitrogen cooling system would do is heat up, and possibly create an explosion when it turned back into a gas due to the immense amount of pressure it would cause.

No, it wouldn't. You obviously keep the cooler external DUH! God, do you have the brain of a 5 year old? If someone needed a frozen board to reach 500mhz then reaching 1ghz would need a contantly cooled to below freezing point board. Get where i'm going with this?

I mean, what good would a liquid be as a cooling system if it wasnt't cooled by a machine? Besides, he wouldnt be able to keep the GBO like that permentently. People have used liquid nitrogen to cool pentium 4's for a massive overclock.

Also I was referring to the point that, Z80's dont crash from heat, so it would take some immense cooling to get a improvment in overclocking that way, and at those temperatures it would be hard to stop ice crystals forming on, and in, the CPU that would cause it to short out.

I see...

permentently, eh?

Um... who said the cooling system had to be closed?

One guy pushed a P4 to the limit, from 3 ghz to 5 ghz. However his safety wasn't guarenteed.

I doubt the GBO chipset could handle such an extreme overclock. In fact I'm surprised you managed to squeeze 50 mhz out of it.

Try overclocking another system, maybe the NES or a Genesis! I mean if it's possible to overclock a SuperFX chip, the sky's the limit! by the way marshall, what are the capacitors for in that mod?
