MP 7,1 CPU upgrade in 2019 Mac Pro

[LeonPro]

I will correct my statement. Premiere Pro makes use of multiple cores as with any program but it can not make use of multiple cores effectively by splitting a single task into different cores as what should happen.

Here‘s from an Adobe Premiere employee:

”Premiere uses multiple cores. Cores are independent CPU processors that can be assigned tasks. Premiere breaks this down with tasks for decoding codecs, applying CPU-driven effects, encoding to specific codecs, etc. Some of these threads may use a core more than other cores, and right now, an "optimal" number of cores is somewhere around the 8-12 mark.”

Someone with a self upgraded Mac Pro CPU moved from Catalina to Big Sur? Any issues? Smooth upgrade?
Thank you in advance for sharing.

Rukuru,

Well, i tried. I think Apple's download servers are overwhelmed by requests for the 12GB Big Sur download. I'll try again tomorrow.

I have RC Two (build 20B28) installed and my update window is telling me my Mac is up-to-date. I believe the build no of the final release is (20B29).

Edit - Solved. I downloaded this Installer from here:

macOS Sequoia

macOS Sequoia brings effortless window tiling, web browsing with fewer distractions, new iPhone Mirroring, and support for Apple Intelligence.

Maybe off-topic:
I have several applications/hardware not compatible with Big Sur -
so it's not a completely smooth transition for some, regardless of cpu.
I will be sticking with Catalina out of necessity for awhile.

^^^^Ya know, that's the beauty of the NcMP. Expandability is just so great Four of my internal SSDs are assigned OS duty. Two are running Big Sur and two Catalina. I can go back and forth at will.

Hi! I'm planning to upgrade my 8-core processor to a 24-core one (from e-bay). Now installed Big Sur. But I read this thread, so the question is: what will i need to run the new processor? Is It tricky?

Hello everybody. I have successfully replaced the CPU - 8 cores with 24 cores. I bought a W3265M QS on ebay. It works perfectly, great performance and stability.
THANKS ALL for this thread, it helps me much.

You sacrificed speed for cores. Tell us your workflow that benefited from this change if you have a chance.

Thats amazing 320949! Could you please confirm if the upgrade survived the PRAM and NVRAM reset and if you did the T2 reset as well, thanks in advance.

Hello!
First start with a new processor showed an amber SOS signal. So, I turned off the MP, connected the MacBook Pro (according to the instructions), then I performed all the necessary steps to revive the firmware.

There was an unobvious moment - the host computer must have installed Big Sur (if your MP have a new bootrom). Otherwise Apple Configurator 2 throws an "incompatible firmware version error" or a "network error" when trying to revive.

The revival process passed very quickly, less than a minute. After that MP booted from recovery volume and asked to choose from options. I have recovered my FileVault password and booted normally in Big Sur.
In my case, it was not needed PRAM or NVRAM reset - everything works well.

 

[blackquartz]

thanks a lot for your comfirmation! I was kind of nervous that the upgrade wasn't posible

Just upgraded from base 8 core Xeon to 28 core Xeon this morning. Upgraded to Big Sur 11.2 before doing the CPU switch. Very easy upgrade, no issues. Swapped out CPU and booted first time, no need for T2 reset or Firmware recovery either. Booted first time without any errors or prompts

 

[LeonPro]

Good to know for those who are on the fence that the latest OS version doesn't need a reset. Probably Apple experienced needing to swap CPU for repair and came with the same road block. Then decided to fix it.

That's great to hear. I have also have a W-3265M arriving in a couple of days (to upgrade my 8-core). Pretty excited for it.

awesome. sorry i just got to this thread. Did you follow any process, youtube video? Or is it a pretty straightforward process?

Very straight forward, no part was what i would call difficult. Counted the number of turns to remove the heatsink, did it an equal number each side, the scary posts around removing the CPU are nonsense, plenty to grip and if you take your time no risk at all of dropping the cpu or bending motherboard pins. Cleaned bottom of heatsink, dropped new CPU in, applied paste, inserted heatsink back into groove. Tightened equally each side until tight, booted and done ...

Not sure if it was relevant or not but just before I swapped out CPU, I upgraded to Big Sur 11.2, no T2 reset or any other type of intervention was required after I swapped it out and booted first time.

Well, I just did the upgrade from 8-core to 24-core on my machine. Running Catalina 10.15.7 it was actually a simpler process than I'd expected (having watched a few "tutorials" on youtube).

With the machine on its side (rather than upright) it was all pretty simple and painless.

And the jump in Geekbench scores is pretty darn nifty (this is my maxed-out 12-core 5,1 vs the 8-core 7,1 vs today's new 24-core build):

Where did you buy the 24 core chip for upgrade?

can you link the youtube videos you followed? Very interested in this upgrade, but hesitant to get in there. I successfully did a swap on the 5,1. Do you think its easier?

I got lucky and found a guy in the US parting out some Xeon builds on ebay.

This one gives you all the details you need:

I wouldn't call it any more complicated than swapping out a CPU on a 5,1 (and simpler than doing a dual CPU upgrade).

The retaining clip for the CPU is simple to put in place, and there's little grooves that make placing the CPU in its tray pretty painless.

Just remember to get a photo of the CPUs orientation, before you pull your stock chip out (so you'll know which way to put the new one in, once you get to that).

I'm confused. My 2013 12-core trash can gets 3371 single and 31519 multi-core. Why are these numbers so low on a 7-year newer machine with 2.5x the cores?

I’m going to assume you’re running Geekbench 4 instead of the newer v5?
