Thanks for the Replies. FWIW the HP Z420 has been overclocked
HP Z420 , Xeon 1680v2 @ 4.4Hgz all cores
Look around in here.
Can someone please let me know the version of Intel XTU they are using on an HP Z420 to overlclock their CPU? The CPU I am trying to overclock is the Intel E5-1650 V2, on a Z420 running Windows 10 Pro 1909, all latest patches. System has 64 GB of Hynix DDR3 1866MHZ Unbuffered RAM, & a GTX 1070...

The HP Z4 G4 did come with different chipsets for the different CPU families. But Dell and HP both offered unlocked CPUs and X299 versions.
The HP guys seem to favor Intel XTU. The Dell guys use Throttlestop more. The X299 Dell is the T5820X.
So the question still remains is the W Xeon itself locked, or is it just the matching C422 chipset?
Maybe Intel feels they have more control at the chipset level than the BIOS level. LGA771 and LGA 775 didn't swap until the tape mod for that came along.
