Successful OC of A3640!
« on: February 05, 2006, 06:06:54 AM »
After performing the modifications listed on http://members.iinet.net.au/~davem2/overclock/a3640.html I am pleased to report my A4000D is now running flawlessly at 33MHz! Using a rev 3.0 A3640, the original 25MHz CPU. A fan, of course, has always been attached, and still keeps things nice and cool. I managed to attain 28MHz without the delay line mod, but decided what the hell and went for it... Made the mod, popped in a 66.666MHz oscillator... BINGO!

I'm just so psyched, I thought I'd share my success with yawl. :hat:

A4000D, A3640 OC-36.3MHz, custom tower, Mediator A4000D. Diamond Banshee 16M, Indivision AGA 4000, GVP HC+8.

Mac Mini 1.5GHz, that might run MorphOS someday, when the fools who own it come to the realization that 30 minutes just isn\'t enough time to play with it enough to decide whether or not you like it enough to cough up $200.

 - Someone please design SOME kind of DIY accelerator for the A4000. :D -

Don't have before benchmarks, didn't think about it at the time. Tho I can toss in my 50MHz xtal...

Installed an IDE drive in place of my Compact Flash drive, so I had to reinstall everything. Benchmarks forthcomming.
