As was indicated in another response, the A3000 stock only came in two
flavors, 16MHz ad 25MHz, so if you had a 16MHz machine, you could
technically switch the speed to 25MHz for a 25MHz Processor.

Unfortunately, though, I have yet to see an A3000 motherboard that did
not have the 030 processor soldered to it.  The one I had, and those
that friends still have all have the 030/25 soldered to the
motherboard.  For this reason in particular, you should look more
towards an accelerator board.

Another solution, if you know how to handle a soldering iron, is to do some soldering on the motherboard. I'm pretty sure there is a way to double the cpu speed on an A3k. I'm not very sure how to do this, but certainly someone else is.

There are hacks on aminet (under tree->board->hack) which have people
ALLEDGEDLY done the same kinda thing successfully. I'm not very
technically competent - (I plugged my IDE cable in the wrong way and
fried my Seagate HD - It's a long story that involves tooting on doobie,
going home believing you can change the world, and suddenly finding
yourself "tinkering" with your Amiga) - but if you can plug the CPU in,
change the "crystal", and do some soldering like that other bloke said,
it might just work.

Another point is that your Buster chip may have problems. I'm NOT
talking about the A4000/Rev9 dilemma, but apparently the common A3000
rev6(or)7 Buster had some kinda problem on the 16mhz A3000 and was
stablised to work on only 16/25mhz models. Doing something like the
above may close all sorts of wobbly things to happen (becuase your
altering the motherboard's processor and not an accelerator card's).
Check out the A4000FAQ and look under "The definitive Buster".

I remember the last time I quoted something out of a mag about a kid
swapping his 7mhz 68000 for a 12mhz 68000 one out of his
Genesis/Megadrive and I got pounced on by hundreds of vicious miggy-pros
for gross error. Therefore, I'm only suggesting; not telling you the
solution.

I'd best go before I offend anyone ;)

One itty bitty problem... some PCB uses multi-layered circuit board... and
soldering iron can easily distroy the board... one reason that I'm somewhat
reluctant to modify my UWSCSI card... :)
