Asus Dual RX 580 8GB in Mac Pro 3,1 (2008) in 2020

Installation of an RX 580 in a Mac Pro 3,1 from 2008 is it worth it??
Did it work??

Well yes sort of!!
The Mac Pro 3,1 was from the $100 Tech haul

Dual 2.8 Ghz Quad Core Xeon processors had the HD 5770 installed, ended up putting a 250GB SSD in bay 1 and 2 3tb HDD's in bays 3 and 4 in a software raid one for storage.

Wanted the RX 580 Metal support and the graphics compute power for rendering and exporting videos. Well for better performance may have to wait for my unicorn the Mac Pro 5,1 Dual processor. I will find it!!!


macOS Mojave patcher from @DosDude1

Well the install did not go exactly as planned.
The Mac Pro 3,1 dose not have the SSE4.2 instruction set so the drivers for the RX 580 will not install properly. High Sierra appeared to be working and showed the card properly but there was no video acceleration. @DosDude1 to the rescue again. Installing Mojave with his patcher tool.. Link in the description Got the RX 580 working. Although not the best seems to be running in slow-mo in in OS X and just ok in Windows 10.

Success RX 580 8GB Card Working in Mac Pro 3,1

Was having sse4.1 issues .. Thanks to @Dosdude1 the patch is in Mojave. Was not ready to go up to Mojave but was the easiest way to do it.
So in looking for upgrades for the Mac Pro 3,1 do your due diligence on finding compatible upgrades.  I did not.. there for ID10T errors..

RX 580 8GB Failure in Mac Pro 3,1

Tried putting the RX 580 in ... Showed up in system as RX 580 but would not load any graphics acceleration what so ever even with an external power source.. so back to the drawing board..

Back to the HD 5770 for now

$100 Tech Haul an Apple affair

I am an "ID10T" in technical terms!!

Keep me off of the Market Place, Offer Up, Craigslist and the like.

Well needless to say here is the run down.. Later videos will go through the full installs of OS X cleaning, repairing, and testing the systems to make sure they will be good for the next home they get.

**** Who knows I may gift one or two of them here on the channel so make sure you are subscribed and hit that bell to know when new videos come out!! ****

None came with power supplies and only 1 or 2 hard drives and batteries / Memory will have to be sourced later.

A Dead Power Mac G5 Dual 2Ghz maybe @HrutkayMods Wants it!
Thank you so much to him for creating his channel, all the videos have been instrumental in helping me with some of the things I have been able to do with the Mac Pro's.
Check him out here:

Also a big thank you to @dosdude1 for the help with getting unsupported OS X versions on older equipment. With out his diligent work none of this would be possible. We would all be stuck with El Cap or the dreaded Lion. UGH!!

And Finally the one I was really after!!

Building the Beast Mac Pro 1,1 Dual Quad Core 3GHz

It has been over a week since the last Post on the $20 Mac Pro 1,1 find.

In the condition it was purchased it was perfectly usable in 2020 even though it was stuck with El Cap.

But can it be better?

Upgrading from the dual Woodcrest Xeon 5150 dual core processors running at 2.66 GHz with 4mb L2 Cache..

To a matching set of Clovertown Xeon X5365 Quad Core processors running at 3 GHz with 8 mb L2 cache.

On a side note the ATI X1900 that came with the system is not compatible with El Cap so an Nvidia GTX 750 has been working but does not play well with others so after the benchmarks and other tests it will be permanently replaced with an ATI Apple Radeon HD 5770 1 GB. Not the best card out there but it does have a DVI port and 2 Mini Display ports.

Now this is just a quick run through on the replacement of the processors if you want more detailed run down let me know in the comments and I will try to put to-gather something more detailed.

You will need a 3 mm hex wrench with an extension, a Phillips head screwdriver, and Rubbing Alcohol 95% or better, or Wipes. Thermal paste and new processors. The only gotcha I can see with this is the thermal sensors on the heat sinks you need to be careful with the connectors on the logic board. Other than that it is pretty simple to do with the elegant built from apple.

Was it worth it? Lets find out.
