E5450 in Mac Pro 2,1

two things, first, I have had good luck with removing heatsinks from CPUs by twisting them clockwise/counter-clockwise to break the bond of the heat transfer paste. Though on older CPUs that paste can bond like 2 part epoxy!

2nd, some sites, and this is one, have horrible search functions. After they comb through several irrelevant pages of results, folks often just post a new topic. We have become spoiled by google search, and expect the relevant results to be handed to us on a silver search platter.

The stick to the carrot here is that people will be chided for reviving old topics!

Why would anyone search just MacRumors unless they were looking for a particular thread they had in mind? And even then you can use a exterior search engine to search only this site... So you're not limited to the search facilities here alone.

StartPage is best! Or maybe Google if you don't care about privacy.Just search the whole net and get the good stuff!

Not only. Real world experience confirms this. There's no microcode and CPUIDs for Harpertown CPUs in 2,1 EFI.
However it should loook more like this:
1,1/2,1 Woodcrest, Clovertown
3,1 C0 Harpertown

Which I learned the hard way

Hi All,

I know this thread is really old but just so that you all are informed. I am sure it is possible. Please watch the youtube video below.

We are working on a modified firmware that would able run 5400-series Xeons on a Mac Pro 1,1/2,1. Our latest version may actually work, but has not been tested yet.

Status August 11, 2020: We seem to have navigated the Pre-EFI Initialization part of the firmware and are now making fixes to two EFI DXE modules. Below are my latest fixes to SEC core.

There are reports, that a Mac Pro 1,1 can work with a combination X5365 / E5450 with standard firmware. Both processors are 3 GHz quad-cores. Unfortunately I have not had time to test this combination.

Please watch the youtube video below.

This guy on the video is wrong. He puts the X5365 in the "A" socket. On a Mac Pro 1,1 the "B" socket has the boot processor. No wonder it does not work.
