HP GRID K1 16GB Workstation Card

This HP GRID K1 J0G94A accelerator targets virtual desktop infrastructure and high-performance compute inside HPE ProLiant servers. Four GPUs share 16 GB of DDR3 memory, each slice providing 4 GB and 192 CUDA cores for concurrent workloads. The PCI Express 3.0 x16 interface fits supported Gen8 and Gen9 platforms directly.

Passive Cooling With 6-Pin Power

Passive cooling removes onboard fans, relying on server airflow to manage thermals at the 850 MHz core clock. A single 6-pin auxiliary connector supplies the board, keeping cabling simple in dense racks. Memory runs at 1782 MHz effective across a 128-bit bus per GPU.

Dual-Slot Form Factor For ProLiant Bays

The card measures 10.5 inches by 4.4 inches and occupies a dual-slot width, matching the ProLiant DL380p Gen8 and DL380 Gen9 brackets. No active fan means one less moving part to service. Builders needing active cooling or consumer display outputs should choose a different accelerator.

Questions about this item

How do I install the HP J0G94A GRID K1 into a ProLiant DL380p Gen8 server, and what step is often missed?

Insert the dual-slot card into a PCI Express 3.0 x16 slot, then attach the 6-pin auxiliary power connector; the power cable is the step most often forgotten.

What maintenance or replacement will the passive cooler on this 16GB GRID K1 need over time?

The passive cooler has no moving parts to replace; schedule regular cleaning of the heatsink fins with compressed air to prevent dust buildup that reduces thermal performance.

At what point does the 128-bit memory interface become the limiting factor during sustained compute workloads?

The 128-bit bus and 1782 MHz effective clock cap memory bandwidth, so bandwidth-bound kernels hit that ceiling before the 768 CUDA cores reach full utilisation.
