GVP A2000-RAM8: do you know jumper settings?

[starf81]

Hello!

Inside my new A3000, I've found also a GVP A2000-RAM8 card.
Do you know its jumper settings? Unfortunately my Amiga seems accepting only the ram onboard and not the 30-pins simms. The previous owner said me that the card works perfectly so I think it can be only a wrong jumper setting. Can you help me?

Here is the card: LINK 1 and LINK 2

Thanks in advance!

I take it you've tried the combination from the photo on Amiga Resource?

J5  OFF   J3 OFF
J6  ON
J7  OFF
J8  ON
J9  OFF
J10 OFF

J15 ON

J15 is in the centre of the board, lower left of the QFP chip.

Hi,
Here ya go, don't know if the text formatting will be okay when I post this:

MEMORY     DIPS      SIMM       J5  J6   J7   J8  J9  J10
(MB)     PRESENT   LOCATIONS
==========================================================
2          YES     All Empty   OFF  ON  OFF  OFF  ON  OFF
4          YES     CN12-CN13   ON   OFF OFF  OFF  ON  OFF
6          YES     CN12-CN15   OFF  OFF ON   ON   OFF OFF
8          YES     CN12-CN17   OFF  ON  OFF  ON   OFF OFF
8*         NO      CN12-CN13   ON   OFF OFF  OFF  OFF ON

*Note: This configuration uses the SIMM8 - 4MB which requires that only two of these are present and that there are no DIPS in their sockets.

J6 and J8 ON as per photo IS the right setting.
