Hi to all !

From 8600 to i7 8700k but the system gives me a message , the cpu is unsuported on the system . 

I saw in the list of suported cpu's is 8700k , but wont work

@9a3,

Welcome to our HP Community forum!

You’re right, an i7-8700K should be compatible, like this HP Z2 Mini G4 Workstation User who successfully installed an i7-8086K or this User with an i7-9700K.

Please try this:

• Make sure you got the latest BIOS version (01.08.11 Rev.A) from here: HP Z2 Mini G4 Workstation Software and Driver Downloads | HP® Support. You'll have to reinstall your old processor in order to do this. I am hopeful that this will resolve your issue.

• Please inspect your i7-8700K carefully for any damage, discolorations or debris stuck on the CPU's business side.

• Though I haven't seen many cases, but there is a slim possibility that your particular motherboard is blocking processors with TDPs over 65-watt -meaning, it could be blocking 95-watt TDP processors such as the i7-8700K.

@9a3,

Whilst thinking about your issue, try this:

Clear CMOS / NVRAM Reset:

Why: Residual settings in NVRAM may conflict with the new CPU’s power/feature profile.

How:

• Power off, unplug AC.

• Press and hold power button for ~15 seconds.

• Open chassis.

• Locate CMOS battery (usually a coin cell) → remove for 10 minutes.

• Reinstall, boot system.

Some Z2 Mini G4 units also have a CMOS reset jumper near the M.2 slot -check the motherboard silkscreen for CMOS or CLR_CMOS.

Kind Regards,

Hi and tnx for replay ! 
I try all this before but still not working . 
in the end I find a i7 8700 , not a K version and waiting shipment. 
I think is the best way without head pain .
