I had a similar problem myself in the past but with the 2630 card. If you had your HC+8 initially set for 8MB, maybe you need to re-adjust the jumper on the board for 4MB. Also, you can jump the memory on your HC+8 up to 6MB with no problem. Since you have 2MB on your 2320, it leaves you the option to install another 6MB (2MB + 6MB). Just remember to change the jumper setting on the HC+8 board.
