GVP RAM32 board with A2000-030
« on: May 11, 2018, 10:06:43 PM »
So I've got this in my 2000 with 8MB RAM installed and was wondering if I could install 4MB simms for a total of 32MB RAM.  Everything I've read said it's not possible. That only 8MB is available on this due to the 68030-25 cpu.


Is that right?  It really doesn't make sense that the speed of the cpu limits the amount of RAM.

And everybody restated exactly what I already knew.


I want to know WHY?


Why is the 25MHz board restricted to 8MB.


Why can it not use the higher RAM amounts?


Doesn't make sense to me.

THAT'S what I wanted to know!


Thanks Thomas.

What do you think? Because the 25Mhz version is the entry-level board, and GVP wanted to create some incentives for users to buy the more expensive variants. The glue logic on the board is different, and 8MB is the limit the board can allocate in the autoconfig area. 32-bit access requires additional logic, or at least different programming of the board logic.
 
From a product definition point of view, this makes perfect sense to me.


If you don't like this answer... well, "Because they decided so". That's it. Too late to complain about.
