Default Upgraded CPU - shows as untrusted software

I recently upgraded the CPU in my Dell 7920 workstation, from

* 8-core, 16-thread 2.1 GHz, Intel Xeon Silver 4110
to
* 26-core, 52-thread 2.0 GHz Intel Xeon Platinum 8167M.

(Yes, clock rate dropped a bit, and single-threaded performance of this CPU is not great. but it was relatively cheap (£300 GBP used). The better CPUs are seriously expensive!

I see in the log file

Code:

The RAM in this machine is far from optimal. I have a couple of 32 GB DIMMs, but they should be installed in groups of 4 identical ones for these Xeons, so I need to add two more DIMMs of some sort. My plan was to replace the 32 GB RDIMMs with 64 GB LRDIMMs (load reduced type), but I have had one Kingston LRDIMM on order for more than a month. I have the money to buy 3 more, but I'm reluctant to do so because of the delay in actually getting them.

The status of my CPUs shows "Recently seen untrusted software", which is a bit inaccurate, as the software is unchanged, it is the hardware that should not be trusted! (I did run the stress testing on this, and found no problems).

This machine has been on/off more than I would have liked, as I am booting multiple versions of linux on this ast different times. I will drop this computer once the workload is finished.

Should I merge the CPUs on the Gimps website or leave them sepparate. I guess they are different CPUs, but they are crunching the same work.

That is totally up to you.
I have merged many times after CPU upgrades without issue.
