I think you need Xeon due firmware limitations.
The Xeon W3570 is out now, though probably in limited supply. It is a 3.2GHz processor that you should be able to get for $600. I really wouldn't count on the Core i9s working in the current Mac Pros.
Would W3570 work? Is the upgrade process similar to the one in a PC?
1. Yes, you can use the i7 parts in that system. Search MR, and you'll see a few people that have done it.Can you upgrade the cpu to i7 extreme 3.33ghz or should i wait for a core i9 will this work in my machine or should i get the xeon equivalents
Seconded. I've read bits and pieces online; the i7 causes sleep mode problems, amongst other things...
A shame given the cost, but it's a Xeon and I'm surprised people got the w3580 to work... Wish I had $1000 right now, but mastercard needs to be paid first...
I run a i7 975 without one issue. Not sure why there were problems reported. My system wakes and sleeps without a hitch.
Nice to hear, thanks! I might go that route then since I've spent more on replacement 3D rendering and other apps lately... (did you have to replace the RAM at the same time? )
