Found this information:
"Aopen offers the PA2000 in three configurations, 8MB, 12MB and soon to be released 16MB."
As I know the voodoo2 can adress only 12mb of memory.
Thats interesting !

see link below:

If its possible to have 16 Mb on a regular v2, on sli mode will be 32 Mb...for gaming is a new perspective.
Imagine nfsmw on v2 sli !

P.S. Have somebody try to add the extra 4 Mb ?
