HP Z2 mini G4 Workstation extended CPU support
Hi all,

I have an HP Z2 Mini G4 Workstation - details here:

This comes in two versions: 'Entry' and 'Performance' - I have the 'Entry' version.

The entry version only supports a handful of CPUs:

Intel Xeon processor E-2104G
Intel CoreTM i7-8700 processor
Intel CoreTM i5-8600 processor
Intel CoreTM i5-8500 processor
Intel CoreTM i3-8100 processor
Intel PentiumTM G5400 processor

But the 'Performance' version supports a lot more, including i7-9700K and i9 CPUs...  (I had already upgraded the Power Supply to the 230w version to support the higher TDP of these.)

I tried my 'Entry' version with an i7-8700K and an i7-9700K and got a 'CPU unsupported' before boot.  Both versions use the same BIOS - is there any way of enabling the extended list of supported CPUs on the 'Entry' model...?

I have attached the bin of the BIOS.  Let me know if you fancy a challenge and need any more information!
Post a screenshot of third (Mainboard) tab of CPU-Z with native CPU.
Make a photo of the screen with 'CPU unsupported' error.

Download Intel CSME System Tools v12
I need results of MEInfo on this system.

I'm afraid I no longer have the CPUs that don't work, and am trying to remember the exact wording...  It was in a red font, before the BIOS splash screen.  I think it said "CPU not supported".

Hope this is udeful? It's a mini-workstation with the Intel C246 chipset, not a laptop, if that helps.
No CPU - no help.

Hi Deathbringer,

If you think there's something you can so, I'll get my hands on one of the unsupported CPUs.  Grateful for any assistance!

Any chance you'd be willing to help..?
I can't help without a photo of the screen with 'CPU unsupported' error.

OK thanks, let me see what I can do.

So I bought another 'unsupported' processor (i3-9100)... and it worked.  I'm wondering if it's because the TDP is also 65W, where the K chips were 95W.  Am going to try a non-K i9-9900 next...
OK so the i9-9900 works, so I'll just stick with that. Many thanks anyway!
