A3640 rev3.1 68040@25mhz CPU Amiga

[alexh]

Dont listen to them. The A3640 offers a BIG speed boost over the 25MHz 030 inside an A3000.

BUT:

In an A3000D they get very hot (unless you can find an L88M chip) and really require you cut vent holes in the floppy disk mount plate.

I would always recommend getting a Cyberstorm 060 with Rev6 if you can afford one.

Sounds like you were either not running a well patched AmigaOS. Or all you did was load WB and open a folder marked WHDownload ;-)

With patches to move as much stuff as you can to FastRAM, to use the CPU instead of the Blitter, SFS etc. the speed increase is noticeable. (or at least I thought that it was)

I've never had any heat problems with my A3640 in the A3000, although mine may be rev 3.2.

Card revision has nothing to do with heat production. It's all down to the revision of 040 CPU you have.

(D43B, D50D, D98D, E31F) : (E42k) : (K63H) : (L88M)

HOT -> COLD

Correct me if I'm wrong, but FastRAM and CPUBlit utilities work with '030, as well.

No correction required.

And, since the 3640 offers no on-board memory, there is no speed advantage using a 3640 for these vs. using the standard '030.

A faster speed of execution and better caches helps. Things like LHA extraction, running a TCP/IP, were all faster with an A3640 in my old A3000. Maybe you had caches switched off or something?

Admittedly, I did not test SFS (it wasn't out back then -- this is back in AmigaOS 3.1 days)...

SFS has been around as long as I can remember but yeah.

I just assumed that was a typo. I dont think you can get an 030@50MHz card for the A3000 can you?
