EliteDesk 800 G8 M.2 PCI4 slot

[adispy]

Hello,

I just purchased an EliteDesk 800 G8 to run my ESXi VMs, and but no matter where I looked I cannot identify which M2 slot is the M.2 PCIe 4 x4. Based on the manual, there is a v4 and a v3 M.2 slot but don't know which one is which. I will want to run the VMs on the v4 off course since it has better speed.

What I noticed on the motherboard is that SSD1 has a white slot and SSD2 is black. I don't know if this matters, but just an info.

Any help will be much appreciated.

Thank you,

Is the EliteDesk 800 G8 a mini or a tower?

Hi,

Thanks for the reply. It is a SFF, but I managed to fix it by resetting the BIOS (take the battery out and power it with out it). After this, the system recognized the all 128GB of RAM.

Thank you,

Great! 

That is good to hear.

Sorry, in the speed of reply and handling other issues I was replying at another problem.

It is a SFF and right now I am installing Windows 11 on it and do some speed test and switch the SSDs between ports. Maybe this way I can find out the v4 M.2 port.

I figured you were answering something else. You answer did not quite fit with the question you had asked.

One nice thing to note is that your PC will accept PCIe NVMe Gen 4 M.2 SSD types.  

Did you mean to say Gen4 instead of v4?

"switch the SSDs between ports" 

I expect that doing that  and bandwidth tests would be the simplest way.

Yep, that's what I did in the end and based on speeds I found out that the Gen4 slot is the white one, and the Gen3 slot is the black one. Something to put in the manual.

Thanks for your help, much appreciate it.
