This Board for 2 CPU is OK for my 4.1 → 5.1 Mac Pro

[FoxxMulder]

Hi guys i need a little help.

I want to buy a dual mother board for my updated 4.1 → 5.1 - 2009 Mac Pro.

I see this in Internet.

Anybody can confirm the compatibility with my Mac Pro. Thank you very much.

Also i want to know if the dual disipador for this mother board are the right in.

That is not a " motherboard" it is the "Processor Tray".

I recently bought a replacement Processor Tray with 32 gb of ECC RAM from this Ebay seller.

Those are all 2009 parts in the picture. You can tell because there is no bracket for the CPU sockets, and the entire bottom of the heatsink is flat, 2010/12 heat sinks have a smaller square.
But if that is all you get you will be missing actual aluminum tray and screws that that board mounts to, as well as the black plastic support clips that delidded CPUS use.
