Questions about this item

What DDR4 ECC memory speed and slot count does the Z4 G4 need for its four-channel architecture?

The workstation uses four-channel DDR4 ECC memory at 2666 MHz across 8 DIMM slots, two per channel.

Can the existing Quadro P1000 and a second GPU share the two PCIe x16 Gen 3 slots?

Yes, the board supports two PCI Express x16 Gen 3 graphics cards; power connections depend on the chosen power supply.

After setup, how do I confirm the 1 TB NVMe SSD is the active boot drive in Windows 11?

Open Settings > System > Storage and verify the 1 TB NVMe device is listed as the boot volume with Windows 11 installed.
