ummm....ok.

But the CPU and at least the memory have clocks. That's why you can't take a cheap bit of old 66MHz RAM and plug it into your new core 2Duo computer and expect it to work.

Even when overclocking a PC there are settings that work and settings that don't. The ones that are stable occur when the new speed is divisible into all the native component speeds. The ones that don't are a result of mismatches where one component is talking faster than the other.

Any CPU will have a speed at which it runs. Same with memory. It is far more likely that the crystal you are futzing with is the one that controls overall system speed. In that case, if you jack it up to 32.whatever, the other components are not able to recognize the signals.

You need to check the native speed of all the components to determine what speed the components can operate at, then find a common setting for them all. Just plugging in crystals pel-mel is as likely to damage the device as make it work at a higher clock speed.

And I can't see that a faster chip will do anything except distort playback. Remember the watch? didn't work so well after the transplant. By your own assumptions, these devices are "cheap" and you think it likely that the crystal you are replacing is "the main" clock. In that case, instead of getting 24 frames per second in a video, you would be getting 32.7.

It's not like a PC where it would then be able to theoretically do more in less time, it's a simple processor with one task. Speeding it up will likely just produce garbled or chipmunk like audio and if you get video it will look like those History Channel shots of WWI where everyone is moving quickly.

I wish you the best of luck on your experiments, but unfortunately, I can't see what the gain is from it. MAybe you should instead look at ways to increase the memory and have the chip buffer more so it feels less slow? That last part could at least theoretically be done by editing the firmware.

...oh, that is likely needed to do what you want as well. I would think the firmware might have some info what the chip should be looking for in the rest of the system. Like the BIOS settings on a PC motherboard...
