Questions about this item

Will the 2666MHz DDR4 ECC memory work with older DDR4 modules I already own?

The workstation uses four-channel DDR4 ECC memory at 2666MHz across eight DIMM slots; mixing with older DDR4 modules is possible but all memory will run at the speed of the slowest installed module.

How can I confirm the Quadro P1000 is running correctly after setup?

Open Device Manager to verify the NVIDIA Quadro P1000 appears with 4GB GDDR5, then run the NVIDIA Control Panel to confirm driver version and Mini DP 1.4 outputs are detected.

What cables or accessories come in the box versus what must be purchased separately?

The tower includes the Xeon W-2135, 64GB DDR4 ECC, 250GB NVMe SSD, Quadro P1000 with four Mini DP 1.4 ports, DVD+/-RW drive, and Windows 11 preinstalled; display cables, Thunderbolt 3 adapters, and additional storage drives are not included.
