Boot Camp Posted January 14, 2008 Share Posted January 14, 2008 Apple sells up to four ATI Radeon HD 2600 XT, but only one NVIDIA GeForce 8800 GT 512MB with the Mac Pro. Does this mean the Mac Pro can only support one 8800 GT?

A.I.Ghost Posted January 14, 2008 Share Posted January 14, 2008 No it doesn't. :-) Previous version offered up to four 7300 nVidias or one single X1900Pro, correct? On the hardware level, it supports up to four 8800Ultra (not sure though if it is 4times 8x speed or less), the only "brake" are drivers.

sarahbau Posted January 14, 2008 Share Posted January 14, 2008 It might be a limitation of power draw. The 8800GT uses about 60w more at load than the 2600XT. However, I can't see any technical reasons why it shouldn't be able to use at least two of them. The Mac Pro has two PCIe 2.0 16 lane slots, but only one of them is double-wide. Maybe with stock cooling, two 8800GT cards next to one another would get too hot.

bonestonne Posted January 14, 2008 Share Posted January 14, 2008 its like that as a marketing ploy, i assure you. the brand new mac pro supports up to 8 30" cinema displays. they can't claim that and then not make it available with all options. contact apple themselves and ask. there has to be a possibility. but the heat is an issue.

They don't have to make that available with all options. They clearly say that it supports 8 30" displays using 4 2600XT cards: Requires installation of four ATI Radeon HD 2600 XT graphics cards, each of which provides support for up to two 20-inch Apple Cinema Displays, 23-inch Apple Cinema HD Displays, or 30-inch Apple Cinema HD Displays.
