Quadro NVS 450 Multi-Display Workstation Card

The HP 490565-001 Quadro NVS 450 provides four DisplayPort outputs driven by dual GPUs, each with 256MB of GDDR3 memory on a 64-bit interface. It targets enterprise IT environments that require certified stability across four 2560 x 1600 displays from a single PCI Express x16 slot. The fanless cooler ensures silent operation in dense workstation deployments.

Sustained Load Behaviour

The dual-GPU architecture splits the 512MB total frame buffer into two 256MB pools, so each GPU manages its own 64-bit memory path during extended multi-monitor workloads. Driver-level NVIEW and Mosaic Mode distribute desktop composition across both processors, keeping frame times consistent when all four outputs are active. The passive heatsink relies on case airflow rather than a fan curve, so thermal performance scales with chassis ventilation.

128-Bit Aggregate Memory Interface Decides Fit

The card presents a combined 128-bit bus width, yet each GPU is limited to a 64-bit channel feeding its local 256MB GDDR3 allocation. Applications that require a single large frame buffer or unified memory pool larger than 256MB per GPU will not benefit from the total 512MB figure. Buyers needing more than four displays or a single GPU with a wider memory path must select a different model.

商品問答

Does the fanless cooler keep the card quiet and cool during all-day operation?

The card uses a fanless cooler, so it runs silently and relies on case airflow to dissipate heat from its dual GPUs.

What cables or adapters are needed to connect four monitors to the four DisplayPort outputs?

Each of the four DisplayPort connectors requires a compatible cable or active adapter matching your monitor inputs.

Will this PCI Express x16 card work in an older workstation that only has a PCI Express x8 slot?

The card fits a PCI Express x16 slot and will operate at x8 speed if installed in an x8 slot.
