New ZorRAM Image

@ Piru
Which speed test program would you like me to try?

I think memspeed is actually the name of the benchmarking application: http://aminet.net/package/util/cli/memspeed

[Karlos]

Some initial tests of the initial ZorRAM we have received from production.

You just made my 256MB A1200 cry. Happy now?

:roflmao:

Oh yeah, forgot about that one

[Karlos]

But think of the possibilities! What could we do with 1gig of ram?

Not just 1GB of RAM, but 1GB of contiguous RAM (looking at the showconfig shot). If I recall correctly, X-Ray experimented with using Zorro 3 RAM expansions (screenshot in the gallery somewhere), but his memory seemed to be split into separate ranges.

-edit-

See here...

Got any ideas?

Well, I could use MIDI In to mix entire tracks (converted to AIFF) :lol:

Just imagine the time it would take to load them all !

[Karlos]

I estimate that access times of Zorro memory would be around the approximate 10Mb/sec rates- but I have not yet run the memspeed test yet.  When I am back in the office on Monday/Tuesday I will run speedtests and post back the exact results.

I'd certainly expect the Zorro bus to be the limiting factor, rather than the memory itself.

[Karlos]

Hmm so it takes roughly 2 minutes to fill the 1GB memory. That's not very fast ;-)

The theoretical Z3 bus transfer rate limit is, what ~150MB/s ? Of course, the buster puts the brakes on long before that is reached.

[Karlos]

10Mb or 10MB?
Anyways, the CSPPC has UW SCSI with theoretical speed of 40MB/sec, so in principle it can be faster.

Megabytes/second. Z3 is not a serial bus, so quoting figures in Megabits/second would be unusual.
