** Some or all steppings of these CPUs don't work with certain newer Mac Pro firmware versions applied by High Sierra 10.13.5 updates and newer. I don't want to list every CPU that doesn't work with a Mac, but these two are asked about often enough to include here, and they've been verified as not working.
No, the X5687 (3.6GHz quad-core) and the X5698 (4.4GHz dual-core) do not work in Mac Pros. We don't know if the washer-stack trick will work in Xserves as they are physically different than MP, but the other solutions should work. The Xserve 3,1 uses lidless CPUs for both single-CPU and double-CPU models. You need to make up for this gap by replacing the heat pad with a thicker pad. If you keep the lids on, the existing heat pad won't reach the heat sink due to the extra height of the lids. Here is an informational washer stack thread, and here is a really good post with pictures and a step-by-step procedure. Other people have kept the lids on, but added washer stacks (of equivalent height to the lid difference) to where the tightening screws go-this is intended to prevent the heat sink from overtightening and causing damage. (If you don't remove the lids it is very easy to tighten down the heat sink screws too much on a CPU that's too large, resulting in damage to the socket, CPU, and/or board.) Keep the lids on, but be extremely careful about not tightening down the heat sink too much. Buy normal CPUs and pay for de-lidding service. (And here is a post warning against delidding yourself.) Here is thread about delidding yourself and here is a video. Buy normal CPUs and de-lid them yourself. Buy CPUs that someone has already de-lidded. Steam cpu cores for mac? upgrade#
This has a different height than the normal CPUs, so if you upgrade a dual-processor 4,1 Mac Pro with different processors, you need to deal with the height difference.
4,1 dual-processorMac Pro uses a special, "lidless" CPUs (the single-processor models use normal CPUs). 
The X# CPU's tend to have a slightly higher maximum temperature rating than their W# equivalents. You cannot use two i7 or single Xeon processors. Steam cpu cores for mac? install#
For two CPUs, you must install two "Dual Xeon" processors. Steam cpu cores for mac? full#
Installing just one single-processor-model CPU into a dual-processor Mac Pro technically works, but this causes an error state with the CPU fan going full blast. Installing a single "Dual Xeon" processor into a single-processor Mac Pro works fine, and actually increases its maximum RAM from 56 to 64GB. However, if you upgrade to a 1333-capable CPU, your RAM will run at 1333 after an NVRAM reset. As shipped, the RAM runs at 1066 because of the CPU. 5,1 Mac Pros shipped with 1333 RAM even when paired with a Nehalem (1066 only) processor. For the 4,1 to use Westmere CPUs and run RAM at 1333, it will need the firmware upgrade to 5,1, found here:. 64GB in a single-processor Mac Pro using a dual-processor-capable Xeon. 56GB in a single-processor Mac Pro using a single-processor-capable Xeon. People have literally been arrested for selling Intel ES processors on Ebay. Since Intel only loans them out and never sells them, they can also be considered stolen property. In my research at least one person bought an engineering sample that didn't work. You can read more about these here, but they are basically "beta" versions of the CPU provided to OEMs for testing. Some used CPUs for sale on Ebay and elsewhere are Intel Engineering Samples. Macs Fan Control is a popular way to control your Mac's fan and it is available for both OS X and Windows, unlike most Mac fan software. Upgrading to a higher TDP (wattage) processor may increase temperatures and/or fan speed at max load. This is important because in some cases the CPU choice makes a difference. Memory speed is included in these charts. There are probably many unverified CPUs that work, but these are not listed. This includes anything offered by Apple (BTO/CTO), third party upgrade guides and commercial services (such as Barefeats, OWC, or xlr8yourmac), or simply individuals claiming personal success in a forum somewhere (such as MacRumors and Netkas). Any and all information here may be incorrect. 
My intent is, after the content matures, to turn this first post into a wiki so that anyone can maintain it going forward from there. These are asked about over and over and over again, so I thought it would be nice to have it all in one place.Ĭonstructive criticism, corrections to errors, pointing out omissions, etc. The intent is to cover all relevant and compatible CPU upgrades for all Mac Pros. Bokkow and I have created a Mac Pro CPU compatibility list.
