Amiga 2000 GVP G-Force 030 Combo Speed & Memory Issues

[Oldsmobile_Mike]

If the memory on the board is filled up during the boot process the benchmark program will run in slower 16-bit ram. I had an identical "non issue" when I had a system with only 2MB of 32-bit ram and 8MB of 16-bit ram. Confirm that the memory is getting detected in the first place (tons of ways to do this, SysInfo, etc.) and add more. (check Amibay)

A 68030 with no 32-bit fast ram won't be hardly any faster than a stock 68000.  Ask me how I know.  

I'm not familiar with your particular board but I would assume "auto" autoconfigures the memory (presumably into the 32-bit address space), extended - maybe sets it so you run a utility to add the memory?  Just a guess.  My other guess would be that "auto" autoconfigures it into 16-bit space, and extended into 32-bit space.  Some accelerators support both methods.  Sounds like a thorough reading of the instruction manual is in your future.

Are there any settings pertaining to ram speed that you could try? 60ns, 80ns, or the like? Hate to give up on a card but it definitely sounds like you've found the issue. Do you have another system you can test the card in? How about another card you can test in your system? (just to rule out issues with the slot)

Shame you aren't closer, I've got a bunch of 4MB and 16MB GVP simm's from my old G-Force '040 card. Check Amibay though - there was a guy on there making his own GVP-compatible memory just a year or two ago.

If you set it to "extended", is there a utility you need to run to add the memory? What does the manual say about that?
