Using VRAM as fast ram?
« on: April 17, 2014, 11:18:44 AM »
Hi all I have got a Radeon 9250 128mb inside my amiga which is only using 31mb what I want to do is use 64mb of the vram as fast ram so could one of you guys tell how I can achieve this?

TIA Ray

If you are using a Mediator, PCI.library ver 9.7, and the MedConfig tool, then it should be automatic.

Well my accelerator already has 64mb but that's all that shows up at the top of workbench?

Can I ask a question, "Are you using a Mediator, PCI.library 9.7, the MedConfig utility and a compatible PCI video card with more than 1 MB of memory?

Be aware that any memory you do add from the video card will be a lot slower to access than regular fast ram.

Aslong as the pci.library is higher than 9.6 and you have the radeon monitor under devs and you've run medconfig the extra ram will show.

Sometimes double clicking the radeon monitor driver works. A restart is need sometimes after running medconfig.


Anyway I have 250mb from the radeon, 52mb ram from the voodoo 5 as fast ram. People say the ram is slower but tbh not noticeable with games and demos. Although the 060 might be helping out there.

There's your problem your pci.library is too old.

As a side note two Radeons don't play well together :(

Be aware that the ram speed is identical between motherboard and GPU vram due to the higher refresh rate of the vram. Those numbers are in the Hyperion Classic forums.  The fastest ram speed is found on a CPU card such as the CSPPC.

So all I need to do is replace PCI.library with a later version and then run medconfig restart the amiga and it will show up as fast ram?

Probably just put in version 9.7 or 10 of PCI.library and reboot.
