Ordered from eBay Graphics Card Upgare (Ati Radeon x1900xt / Part# 102A5202752 000006) for my new Mac Pro (early 2008). It came in white box with Apple logos. Attached and powered it but I get only "No Signal" on my monitors (LCD: Eizo FlexScan S2401W and Samsung SyncMaster 225BW). Tried different cables: DVI-D Single-link, DVI-D dual, DVI-I Dual and VGA+Apple DVI-adaptor - no effect. It seems like the new card isn't recognized properly? Systemprofile says (Translated from Finnish): Display: Type: Display Bus: PCIe Slot: Slot-1 PCIe: x16 Vendor: ATI (0x1002) Device ID: 0x7249 Revision-ID: 0x0000 Card: Type: VGA-display Driver installed: Yes Bus: PCI Slot: Slot-1 Vendor: 0x1002 Device ID: 0x7249 Revision-ID: 0x0000 Tried also to update the drivers for x1900xt but got the message "This computer does not need this update". Have I received (ordered) a PC card ???
