So we have alt-ram between 4-8MB.. but the only software I know of is the monster software, but this does not seem to recognise or allocate the RAM, has anyone any ideas or any other software I could try ?

I tried doing my own basic program just doing..

x = Maddalt&(4194304,4194304)

But it trashes the floppy on the desktop

EDIT:

Did manage to boot from cart (cart was corrupted with names as well) and did get manage to get a score though..

Thats a pretty low score for fastram. The Amiga 2000 and CDTV rate the 534 at around 16mips when running in fastrom.

Does the ST turn on the CPU caches/burst mode?

mips, meaningless instructions per second...

The caches are on. I turned them off now says 410%.... turning datacache on drops to 377%. But this is screwy stuff I had on the falcon.. apparently datacache does cause slow downs in some cases.

GB6 also isn't calibrated with the alt-ram benchmark files because I had no alt-ram board which I knew ran at proper 8MHz.. So I had to guess at the number.. but I think it was 20% off or thereabouts, but I have never had any hardware to set it up correctly.

but also , figures will be slower as GB6 itself is running the routines from ST-RAM... if GB6 is loaded into fast-ram the routines will run faster and you will get a higher score.. but the floppy is getting trashed when alt-ram is loaded, so I can't do anymore testing until that issue is fixed.

Ah i would expect GB6 to alloc some fast ram, copy the routines over to fastram, run em there and get some numbers.

EDIT: or rather thats how i'd expect meaningful results to be obtained.
