Z620 M2 NVME support in bios update

HP Recommended
Microsoft Windows 10 (64-bit)

Hello All,


Thanks for all the tips and tricks I've viewed and used so far. Mostly getting the boot block date current so I could use the V2 Xeon's!! Much appreciated!! 🙂


Hoping HP might update bios to support the Z Turbo G2's in the future! I'm mean the G1 is OK, But with the lastest CPU update and their BM score nearing 20K, I'd sure like to get the Disc speed closer to the latest round of M2 NVME drives currently available!


Anyone have any other tips or tricks??

Hi Jetman6,


The Z620 has a hybrid BIOS, i.e. it supports both legacy and UEFI installation. However, because it is a hybrid BIOS (and not a fully implemented EFI BIOS) is does not fully support all UEFI devices such as the latest NVMe drives as a boot drive. There are a select couple of NVMe drives that the Z620 does support as boot drives - as listed in the forum. I believe the Z620 will work with the newer NVMe drives but not as a boot drive, i.e. they can only be used as non-bootable data drives.


I believe there may be a work-around that will enable the newer drives to work as boot drives but this involves the use of a USB boot drive that the Z620 reads at boot to load the OS from the NVMe drive. I would suggest you search the forum as NVMe drive compatibility is a regular theme on the forum regarding the HP Zx20 series of workstations.

Well, I wanted more. So I chip clipped it yet again(already did the boot block date) and added the NZVME files to the firmware. Sounds harder than it actually is and works fine. I only used a Saamsung PM951 to see if it worked, I'll be adding a 970 Evo soon!! 🙂
