Quad-GPU virtualization card for Cisco UCS

The NVIDIA GRID K1 packs four graphics engines into a dual-slot, passively cooled board built for Cisco UCS C240 M3 servers. Each engine delivers 768 CUDA cores at 850 MHz and shares a 16 GB DDR3 pool across a 128-bit bus. The card draws 130 W through a single 6-pin connector and connects via PCI Express 3.0 x16.

16 GB shared across four engines

The 128-bit interface running at 891 MHz feeds all four GPUs from one 16 GB frame buffer, so memory headroom is divided by the number of active virtual desktops or vApps. Light knowledge-worker workloads and entry 3D sessions fit comfortably; heavier textures or many concurrent users will exhaust bandwidth and capacity quickly.

Steps up from CPU-only or single-GPU blades

Replacing integrated graphics or a lone GPU with this quad-engine board multiplies concurrent session density inside the same 2-slot footprint. The jump pays off when moving from zero or one hardware-accelerated desktop per server to four, provided the workload stays within the 130 W envelope and the 128-bit memory path.

Questions about this item

Will the card fit in a standard PCI Express 3.0 x16 slot on my existing motherboard?

The card uses a PCI Express 3.0 x16 interface and occupies two slots with dimensions of 10.5 inches by 4.4 inches, so it fits any board with a full-length x16 slot and enough clearance for a dual-slot cooler.

How can I verify the GRID K1 is running correctly once installed?

Check that the system detects four GPUs with 768 CUDA cores each running at 850 MHz core clock and 16 GB DDR3 memory at 891 MHz effective clock, and that DirectX 11 and OpenGL 4.3 are reported by the driver.

Does the box include the 6-pin power cable or do I need to buy one separately?

The card requires a 6-pin power connector and draws up to 130 watts; the power cable is not included and must be supplied by your power supply or purchased separately.
