What's the latest Intel CPU that is compatible with HP Z800?

[chucklor]

I'm looking to upgrade my Intel Xeon 2.4GHz CPU. Is there a list somewhere that shows all the compatible CPU for the HP Z800 Workstation? Any help is much appreciated.

Your specs here.

What CPU do you have installed now???

Thank you so much for the link. In my System's About, it shows Intel Xeon E5530 @2.4GHz. So, based on the link you've provided, the latest CPU that this workstation will accept is the Intel Xeon X5570 and maximum RAM memory is 64GB, correct?

Again, thank you!

The picture of listed processors is from an old QuickSpecs.... for the version 1.  You want to use the later QuickSpecs to get an up to date processor listing.  Searth for Z800 QuickSpecs and don't use anything less than in the 40s.  The latest version I have is 56, from 11/13, and here is the list of HP certified processors for the Z800 from that (which is the very last QuickSpecs version):

There is a search function in this forum which allows one to do some research......

Please use the search bar top left area (which searches only this forum) and look up "upgrade processor in Z800".  And, "Z800 boot block date".

Let us know what your boot block date is from your BIOS.....

You'd not want to put in an unnecessarily old processor if you have one of the newer version 2 Z800s, or waste time and money trying to put in a version 2 HP-certified processor if you happen to have a version 1 Z800.

Is there any information on the Intel Xeon W-2145. Is it compatible with the Z800?

[Z440Roger]

The latest is Xeon X5660 and Xeon X5670 iow 6-core processors. The list provided earlier is old.

No, the Xeon W-2145 is not supported in the Z800. The fastest supported is the 6-core Xeon X5670 but as SDH points out it depends on which motherboard you have.

Thanks for the reply. What about the intel xeon x5690? I saw Amazon is selling some HP Z800 with this CPU in. Does that mean it'll work? How do I determine what my motherboard is?

[Z440Roger · Accepted solution]

Yes, i missed the X5690.

Do the motherboard of the hp z800 works with only one CPU socketed? Or it needs to be the tow of them?
