I am saying this because i saw upgrades that could bring a cyberstorm up to 400mhz.In everyday computing life on internet we need more than 256 of ram unfortunately.
So has anyone ever tried to do it?
Theoretically, no existing version of AmigaOS can use more than 4GB of
address space, since all pointers are 32-bits wide. Not all of that address space can be RAM either, as you have to map hardware into it too. IIRC, ~2GB is the limit for RAM.
However, for any version running on a classic machine, you'll run into other hardware limits before that. For instance, 256MB of Fast RAM is the physical limit for BlizzardPPC boards, since each slot only recognises SIMMS up to 128MB.
On the CyberstormPPC, I think the limit is 128MB. You can, however, add Z3 RAM, so shove a couple of ZorRAM sticks in the machine and you could probably boost over 1GB. However, that increase would come at a cost in performance, since the CSPPC would be forced to access it via the Zorro bus, which is
much slower than it's own local memory bus.
I can confirm, however, that OS4 classic is perfectly usable on my 256MB BlizzardPPC.
