What is the max memory of the A4000

[AntonioX]

Hi all

I just wanted to know what is the Maximum Memory
A A4000 can have, I rember reading some where that the max is 1GB is this true? if so how would it be done.

[X-ray]

I suppose you could have a Cyberstorm with 128 on it, three updated FastlaneZ3 cards with 256 on each, and a DKB3128 card with another 128 on it.
I'd love to do that just for kicks on my A4000T but:

1) I don't know if 3 Fastlane cards could get on with each other.
2) All my Zorro slots would be used up because I already have a DKB3128 board and a Picasso IV.
3) Finding 3 of those updated Fastlane cards will be impossible. I bet there are very few members here who have even one of those, and if they do they won't sell it for less than £300

Shame they don´t produce those DKB3128 boards anymore  :boohoo:

DKB3128 cards would be very easy to make (especially as you could mount 128Mbyte on the card nowadays) but there is just no real market for them. Being Zorro III, A5k, A2k and A1200T's cannot use them. You might sell say 15 maximum. You're not even going to recoup the cost of making them in the first place.

For people with PCI bridge boards (Mediator/G-Rex/Promethius etc.), I am sure that you could add upto 512Mbyte RAM with a PCI RAM card (drivers for Gigabyte's I-RAM anyone?).

[Effy]

Mediator is Elbox their own child. But why not creating an OpenPCI driver for the Prometheus and G-Rex  :-?

[alexh]

Erm, was that English?

I dont know anyone who is a coder and has either a Promethius or a G-Rex.

@ all

Other than  using a DKB3128 as they are very hard to find is there any thing else that can be used to add more ram?

[PaSha]

[insane rambling]
2 MB ChipRam
16 MB motherboard FastRam
128 MB CPU board FastRam

7 ZorroIII slots: 7x FastlaneZ3 x 256 MB RAM = 1792 MB

Total: 1938 MB :lol:

[/insane rambling]

OT: Why the ¤%&£ didn't Phase5/DCE make the CS-PPC accept 128 MB SIMMs?

WTB: Grex PCI A4000D

You can always add smallish amounts of RAM in conjunction with a SCSI controller or HD controller card, but if you are going for the biggest baddest heavy bopper memory monster you need a few DKB3128 boards or a few FastlaneZ3 boards (the updated ones)

Exactly!!
Can this be sorted out/hacked?

Sheesh...what's the deal with so much ram? :-)
Is there anything on Amiga that requires so much ram?

[X-ray]

Ja:

1) Anims (played from RAM through SCALA)
2) Cinema4D
3) Any number of quick dump/temporary disk operations

edit

4) Ego  :-P

[x56h34]

Hmmmmm...if you say so. :-)

[AntonioX]

@x56h34

I just wanted to know if it could be done, and why not have lots of ram just for the hell of it, also also just to say i have this much ram in my Amiga 2 my mates down the pub

[x56h34]

@AntonioX:

Of course, I fully understand the coolness factor of having as much ram in your Amiga as possible. :-)

...it's just that it costs a lot of money, and in the end there's no real benefit from it, unless like our friend X-ray, you actually get to use the entire amount of expanded fast ram. :-D
