Mach64GX acceleration memory limit

[SA1988]

Is it really limited to 4mb? Because, for a bare test, Win95 glitches a lot with 8mb, yet with acceleration turned off completely it renders correctly.
Note: this does not apply to NT (any version above 3.1 since no mach64 drivers exist for such version).

If you look at the Wikipedia article on the ATI Mach64 GX series:

1. The Graphics Xpression model comes with 1 MB DRAM and is upgradeable to 2 MB.
2. The Graphics Pro Turbo model comes with 2 MB VRAM and can be upgraded to 4 MB.
3. The WinTurbo model comes with either 1 MB or 2 MB VRAM, but the VRAM is not upgradable.

So you are correct. Can anyone check what exact model of the Mach64 GX is displayed when the BIOS performs a memory test at startup?

Actually, the bios supports up to 8MB, so are the drivers.

Thank you for telling me. I'm going to do a search for Mach64 GX cards on Google that do support up to 8 BM VRAM.
