Hi! I've installed Samsung 950 PRO on HP Z820 and it works great - I can boot from the drive, and it's fast and so on and so on. But time passes, and I become to realize that it would be more difficult to purchase new Samsung 950, or the drive will be (and already is) overpriced on eBay. So, why I'm writing this - when I was looking into the issue of HP Z820 and NVMe compatibility back in the days here, many folks shared this link https://www.win-raid.com/t871f50-Guide-How-to-get-full-NVMe-support-for-all-Systems-with-an-AMI-UEFI...
so, what I would like to know if anybody tried to do this with HP Z820? any luck?
As far as I am aware, (and has been posted on the forum a couple of times), the HP workstations use a checksum BIOS preventing any modification of the code. If the boot code fails the checksum, the workstation will not boot.
I use a Samsung SM951 M.2. drive as my W7Pro boot drive, (Windows UEFI mode install), on my HP Z620. I actually have the AHCI version of the drive, not the SM951 NVMe version. I just bought another SM951 AHCI drive on ebay at the weekend as I want to try out W10Pro on my Z620. As with most of the earlier generation M.2 drives, availability is only going to get worse.
I also recently purchased a Sabrent Rocket 1TB NVMe to test out as a possible boot drive but I'm not having much luck. Windows 7 doesn't see the NVMe drive unless you apply the W7 NVMe hotfix, and the drive doesn't appear in the BIOS. I was not able to install W7 on the drive. I also tried with W10Pro, and although I was able to install the OS on the drive, the HP BIOS was unable to see a bootable disk when I restarted the computer. I have been testing this M.2. NVMe drive with 3 different PCIe adapter cards; ASUS HYPER X4 mini, Lycom DT120 and a HP Z Turbo G2. There is a recent post on the forum regarding 'compatible' NVMe bootable drives in the HP Zx20 workstations, and several models are listed, including the Sabrent Rocket 1TB drive. I will be sending the member a pm to see if he may able to assist me getting the Sabrent drive working as a boot drive.
