hi FAXVAAG.

in order to have the best performance of phoenix working on
OS 10.6.x snow leopard mac pro's 5.1 insert Phoenix card
on SLOT 3 only.

Phoenix PE4 working fine on any slot of the mother board.
Phoenix PE1 working fine only slot 3 of the mother board.

Put your Phoenix on SLOT 3.

Check info mac/more information/PCIe/slot read if driver is installed,
you need reinstall driver if you move phoenix in different slot
(only one time).


if serial number your Phoenix starting by 5xxx please contact
Active Silicon Support,probably your phoenix need reflash at
last firmware version to working at the best.

for sure at moment you must work at 32 bit


Let we know.....
