Underclocking a CE x86 CPU?

Hey all,
I was wondering if it could be possible to reduce the clock rate of the Celeron M that powers my CE 5.0 device. It's sadly not a topic I know a lot about, but I'm willing to try things out Does anyone happen to know anything about it?

Unless there were dip switches to do it (virtually no chance on modern-ish hardware). You would need to get into the firmware (BIOS) and change either the CPU multiplier or the voltage. The third way of doing it would be via software as part of the power management scheme for the CPU, but I am no aware of anything existing for CE to allow you to do that.

It's an embedded device so there's no BIOS unfortunately. It's a custom implementation of the Intel 854 chipset

Not much you can do unless you want to start replacing resistors to reduce voltages... and I don't recommend it!

There were under clocking apps for ARM devices, but I never heard of these for x86 based CE devices.

I got it, thank you all! I don't think I'll actually have to worry about a meltdown, I don't think they would've designed it without a fan then

It will also thermal throttle if it gets too hot, it's not like early 90's chips. That said, embedded celeron chips were often intended to passively.

Were .net Framework programs capable of underclocking or because of the managed code, it’s not low level enough to access the processor?
If so, there may be some old Windows Mobile / PocketPC prog out there that may run?

They would be processor specific, likely written in assembler.
