more RAM , how?

Send in the experts!

A guy in Holland claims he has a A1200 with 10MB RAM.
DA!
How is this possible?
Did I miss anything?

How can I expand my Amiga 1200 HD with Blizzard 1230/4 with 64MB another way?
I like to use more chip-memory for Octamed.
Help?
Can anybody explain me what to do :idea:
thanks.

Well, i can be possible, but not with Chip memory, it can have 2mb of Chip + 8mb of Fast Ram, total memory 10mb, but A1200 was designed to have up to 8mb of chip, but commodore decrease for reduce production costs to 2mb, for this reason you can set chip memory to 8mb on WinUAE, i'm not sure but i think that i read somewhere.

And as you can see on my signature i have an A1200 with a Blizzard 1230 with 50 Mb of ram, 2mb of chip and 48 of fast ram, using SCSI board for your Blizzard you can plug two memory simms.

Balrogsoft, thank you.

I try to expand for octamed to use longer samples.
Thrue other forum-dudez I found out this programme uses only chip-memory (2 mb)

So a couple of samples in the memory and it is full.
I thought the blizzard would expand the memory, but that was incorrect.

I need to decrease the volumes of the samples to work with is all (to bad  :angry: )
any suggestions?

Octamed Soundstudio can load the sample on Fast memory, i found this:

http://www.soundonsound.com/sos/1997_articles/may97/octamedstudio.html

 Another facility provided with OctaMED Soundstudio is less visible but still important. The Amiga is unusual in computer terms, in that much of the work that would normally be carried out by a main processor is actually performed by some custom-designed Commodore chips, such as handling the graphics display and retrieving sound samples from memory. The snag is that only parts of the Amiga's memory are accessible to these custom chips, and the amount of this so-called 'chip' memory is limited. OctaMED Soundstudio can, where appropriate, load samples into the machine's non-chip memory, and then transparently copy them into chip memory as required. You'd think this might slow things down a bit but, surprisingly, the buffering process turns out to be very fast.

i just printed the article, now I only have to read it at a quiet moment, thank you so much.

@Balrogsoft: Actually, 2Mb Chip was always the maximum intended for the A1200, the idiots in charge at Commodore initially wanted 1Mb Chip to ship so they could then sell an expansion with the other 1Mb Chip RAM and an RTC, that's why we have the clockport, fortunately memory prices dropped sufficiently before release that they ditched that moronic idea.

AGA would have been extended later on to be able to handle 8Mb RAM, but it was never implemented what with the liquidation and all, no produced Amiga was ever going to have anything near 8Mb Chip RAM, Maybe the AAA stuff they were working on before the closure, but that never really got anywhere.

I have got 66MB of ram in my A1200.

2MB of Chip  :-D
64MB of Fast (Single 72 Pin Simm).

Kickstart is shadowed to Fastram (Accelerator utility)..

I like my Miggy1200.

I win until now!!! 192MB! YEAH!  :lol:  :lol:  :lol:  :lol:  :lol:  :lol:  :lol:
but really, who needs all this ram nowdays?

@keropi

Easily topped. I know several users besides myself that have 256 MB fast ram installed.

What it's used for??? Nothing in particular, but it doesn't hurt to have a bit extra ;-)

If we can connect a PPC/PCI/USB to our amiga, why hasn't someone made a hardware thing to expand our chipmem ?

Just a thought.

[keropi]

if u need more chipmem, then grab an A4000... I think u can have 6MB chipram on a 4000...

[ElZorro]

That is not what I am after.

I like my A1200, no I treasure it!

I guess I need another tool to expand the RAM.
I need to know which software or setting I gonne need to access as much as possible memory to use it for octamed v5.0.

That's not true at all. No Amiga can have more than 2 megabytes of chip ram.

The 2MB chipmem limit is a limitation of the Amiga's custom chips. If you wanted more chipmem, you would have to replace the custom chips with new versions which supported more RAM.

PPC cards, PCI busses and USB controllers are not subject to this limitation as they do not rely on the custom chips (except to load driver software or libraries, which are small enough to fit in 2MB chipmem or can be coded to use fastmem).

If you wanted more chipmem, you would have to replace the custom chips with new versions which supported more RAM.

It should perhaps also be pointed out that there is no such custom chips available. 2MB is the chip memory limitation in hardware. WinUAE can have upto 8MB "chip" memory, though.

Oh my peg2 has 1GB of memory ;-)
