Pover 1.2 -- Prizm Overclocking/Underclocking utility

How fine-grained is the control over clockspeed? It would be hilarious to equip CGPlayer with a slider controlling CPU speed.

Haha, that's a superb idea. Very Happy

We have about ten gradations of clock speed, so we could do some fun stuff.

What are you referring to, my Prizm game? If so, it's in the Cemetech archives: http://www.cemetech.net/forum/viewtopic.php?t=7071

Nope. the 87MHz we currently have (possibly 88-89MHz with the CPU clock divisor at 1/2x) is the best we've got; but, that's a huge improvement, still.

90MHz, really? I thought it ran at something like 200MHz (or is that with Nover?)

That has yet to be tested, but I can poke KermM/Spenceboy or someone else who has at least 2 Prizms to try it out.

I tested now with fx-9860 and prizm. Prizm only can transfer files for 9860 at normal cpu speed

with over/under clock, gives error

Interesting, helder/Spenceboy, and please do tell what happens when they're both running at the same clock rate. It seems to make sense why they wouldn't work together at different speeds, though.

Small correction, the default speed used to be 90MHz in old OS versions but they raised the default to 120MHz for a while now.

Hmm, I tried it and it worked fast as a flash (no pun intended), but that was without the 1/2x ICLK divisor. Perhaps try it without the divisor changed; it seems that changing the CPU clock division ratio has a few nasty effects when using the Prizm for certain things.

EDIT: I'm making an update tomorrow, with allowing the user to overclock to 94.3 MHz (yay!). I can technically overclock to 101.5 MHz now, but the MENU screen crashes at that rate, very ugly-ish. Works fine in a game though, such as RainbowDashAttack (built it, that is).

So, more discoveries made; probably more to be made. We are now almost at the Nspire's Frequency.
