Replacing PCI-Express graphics card in G5

Hi!
The 6600 card found HERE is currently at 58 bucks on ebay. I bought one the other day for about 125 bucks. You'll have to be patient and watch closely to pick up a Mac PCIe video card. Tom

Hi-

Add two more:

Radeon X1900 G5 Edition
Flashed (converted WinPC card) Geforce 7800GTX

Hi-

Where would I find instructions on converting a GeForce7800GTX? I'd love to add another card to my PPC G5 quad without spending the same price on it as I would for another monitor!

Apple's "early/late" naming convention doesn't really help with what's on the inside, but officially "Late 2005" was dual-core processors, using PCIe graphics.

How about a snippet from the top of System Profile, and graphics (be sure to leave out SN etc).

http://www.apple.com/support/powermac/

Standard graphics
NVIDIA GeForce 6600 LE with 128MB of GDDR SDRAM, one single-link DVI port, and one dual-link DVI port
NVIDIA GeForce 6600 with 256MB of GDDR SDRAM, one single-link DVI port, and one dual-link DVI port

Optional graphics
NVIDIA GeForce 7800 GT with 256MB of GDDR3 SDRAM, one single-link DVI port, and one dual-link DVI port; or NVIDIA Quadro FX 4500 with 512MB of GDDR3 SDRAM, two dual-link DVI ports, and one stereo 3D port (occupies PCI Express 16-lane slot and adjacent four-lane slot)

Apple's PowerMac G5 Late2005 manuals
http://support.apple.com/manuals/#powermac

"Up to 16GB of main memory Eight DIMM slots hold up to 16GB of fast new 533MHz DDR2 SDRAM. For mission-critical and compute-intensive environments, you now have the option of ECC (Error Correction Code) memory for automatic correction and detection of data errors." - Page #4

The PowerMac 7,2 came out in 2003 with AGP and PCI-X.

Dual core is different from dual cpu or processor and has different meaning. Dual-core made its debut in Late 2005 and included DDR2, PCI Express and other features.

Oh yes, gets asked and answered every couple days!
looking for AGP graphics for PM G5 should be a google click away.

I just picked up a Radeon X1900 Mac Edition for my Quad G5. I put it in the 16x PCIe slot and.....nothing. The computer just hangs there - won't boot. I don't even get to the grey screen with gears. As soon as I pull the thing back out, everything is back to normal. I assumed since it's the "Mac Edition" that it should be as easy as following the installation instruction. Does anyone PLEASE have any info this?

Hi-

Is that a Mac Edition, or a G5 Edition?
There are two cards, with the Mac Edition (512MB VRAM) being for Mac Pro machines, and the G5 Edition (256MB VRAM) being for the G5 dual core.

Very confusing, but none the less, a very important point.

Also, the X1900 requires connection of the power cable that should have been included.
The power cable connects from the card to an auxiliary power connector on the logic board.

It says on the box that it's the 256MB G5 Mac Edition, and there was no power cable included (I bought it on Ebay).

The need for the power cable would explain the graphic with the flashing red (cable) that I see on the screen when I try to boot up! I'll seek one out and post back if that's all it took to solve the problem, or not.

Thank you so much for the information. It's people like you that make the world a better place!

MacSales has one (over-priced I feel) for $28.

Thanks, but yeah, that's a rip-off. The ATI site has one for less than half that: http://shop.ati.com/product.asp?sku=3280778
