Use this guide to replace either of the dual graphics cards in your Mac Pro. The procedure is shown on one card, but it is essentially identical for either.

When you're replacing your card, be sure to reapply a layer of thermal compound.

Before beginning any work on your Mac Pro: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

  1. Slide the lock switch to the right, to the unlocked position. Slide the lock switch to the right, to the unlocked position.

hey! is it possible to upgrade the GPU or is this just for replacing exactly the same part?

Ben - 返信

I am guessing you can upgrade them with OEM parts, but where would we find them?

Fernando Bernardino -

I have the D300s, and would like to upgrade to the D500s or D700s. Where might I find the replacement graphics cards? Also, any recommendations on service providers who would do this procedure?

Chris M Balz - 返信

I'd love to know this as well. The only reason I picked up the ,ad pro was the potential for upgrades. As it turns out D300s are crap. I can't even run boot camp properly.

Is it possible to put Nividia cards in?
