I sincerely doubt any issues you are experiencing are due to the upgrade itself, assuming it was properly done. My opinion is based on the fact that you are one among many hundreds, likely many thousands, running similarly modified Mac Pros without issue. There are many other potential failure points... most in software, but also extending to RAM, motherboard, GPU, power supply and more.

Xeon X5680 and 90 CPUs are pin-compatible with the quad CPUs they replaced in your machine. And, once the 4,1 Mac Pro is running 5,1 firmware, it is for all intents and purpose a 5,1. The only difference between the hex CPUs that shipped in dual 5,1s and the X5680 or 90 is clock speed and power consumption, and the fact the Mac Pro heatsinks easily handle the additional thermal load renders power consumption a non-issue.

Computers are not voodoo; they only seem like it sometimes. With DP9.5, MOTU implemented a lot of under-the-hood changes to the pitch engine. The bugs will be squashed, and it won't be in hardware. :smash:

Thanks to all who replied to my question about upgrading this early 2009 prehistoric beast. As I've got it tricked out with 2 TB of SSD's and don't believe I need the latest I/O options, it'd indeed be great to keep it working for another year (or 2) before we see the modular Mac Pro's.

One more question, if I may: As prices for used Xeons are continuing to fall (at least from the start of this thread), or can this machine use a 5690?

Thanks so much again.

And I cannot help but wonder if having upgraded my machine is somehow connected to issues I am having such as relative pitch mode re draw not working right, and waves automation having problems. Are these and other issues due to a 12 core cpu in a machine meant to be 8 core? Do my issues have nothing to do with the upgrade? I don’t know. But it does make me wonder. I do feel if I got some sort of brand new mac, and started from scratch, I’d likely see various issues resolve themselves. This is all highly technical stuff of course. So to know the answers requires technical research beyond my capability. Just sharing my experiences for what they are worth. Some 9.5 users swear their machines are running very well. Others are having problems. I think 9.51 pretty much sucks and has become sluggish on my machine. Is it the machine? Is it Sierra? Who the heck knows.


I've had these same issues on my non-upgraded machine, so not to worry that you did any damage. :)

Yes! Two of 'em. It's the fastest CPU that will work, and many are running X5690s in modified 4,1s.

I have two single-CPU 4,1s flashed to 5,1s. One runs A W3680 and one a W3690. The X56xx series (which also work in single CPU Mac Pros) are required for dual-CPU Mac Pros as they provide the required interconnectivity.

My guess is the 5690s are the parts that binned better than the 5680s but are otherwise identical to the 5680s. If I recall correctly, both are 130 Watt parts.
