Questions about this item

Will the 256GB DDR4 2666 ECC memory work with my older Xeon LGA 2066 platform?

The memory is DDR4 2666 ECC Registered, matching the LGA 2066 socket specification, so it is compatible with that platform.

How can I verify the Quadro P5000 16GB is running at full performance after installation?

Check Device Manager to confirm the GPU shows 16GB GDDR5X and four DisplayPort 1.4 outputs, then run an ISV-certified application to validate driver operation.

What comes in the box and do I need to buy a monitor or storage separately?

The workstation includes the tower, 256GB memory, 500GB NVMe SSD, Quadro P5000, 1000W PSU and Windows 11 Pro; a monitor is not included and extra drives are optional.
