I take it that there are 68 pin VRAM SIMMs and I think from reading the Developer notes and examining motherboards that the Centris/Q 610/650/800 all use the same 256K SIMMs as the Q700 and Q900. Which other machines use them?
Are these Quadra VRAM SIMMs the same as are used in the 1&2 MB HPV card on the 7100 and 8100? If so, what happens if you install the 512 KB VRAM SIMMs which are used on the 2 & 4 MB HPV card in a Quadra? Are they seen as half their capacity?
Okay, now the tougher question. I like the Q650 much more than the Q700 motherboard, except that the Q650 has a 1 MB VRAM capacity and the Q700 has a 2 MB VRAM capacity. I am looking at installing a Q650 in a Q700 case.
Does the Q650/800 (Wombat) motherboard have the ability to address more than 1 MB of VRAM? I know there aren't sockets available on the motherboard, but does anyone know if the chips have the ability to address more? If so, has anyone hacked more VRAM into the Wombat motherboard?
