HP Inc 340L3AA NVIDIA NVLINK 3-SLOT BRG

HP Inc 340L3AA NVIDIA NVLink 3-Slot Bridge

Overview

The HP Inc 340L3AA is a 3-slot NVIDIA NVLink bridge designed to link two compatible NVIDIA GPUs within a single workstation, enabling them to function as a unified pool of GPU memory and compute capacity. The 340L3AA fits deployments where a single GPU's VRAM ceiling becomes a constraint — AI inference workloads, large 3D rendering scenes, or GPU-accelerated simulations that exceed what one card can address. By coupling two NVLink-capable GPUs, the bridge allows the system to present combined memory to the application rather than forcing the workload to split across a slower PCIe interconnect.

Compatibility

This bridge is designed for NVLink-capable NVIDIA professional GPU cards that require a 3-slot span between connectors — typically Quadro RTX and NVIDIA RTX series boards (such as RTX 4000, 5000, or 6000 class) installed in HP Z-series workstations or compatible third-party tower chassis with adequate slot spacing. Verify your GPU model's NVLink connector position and required bridge width against the 3-slot (0.70 in height, 11.00 x 7.10 in overall footprint) before ordering — GPU pairs with a 2-slot or 4-slot gap require a different bridge. Confirm with HP's GPSR product page for exact validated GPU and platform pairings before purchase.

Installation Notes

The bridge installs by pressing firmly onto the NVLink connectors on both GPUs simultaneously — no tools required for the bridge itself, though GPU installation may require a standard Phillips screwdriver for card retention. Ensure both GPUs are fully seated and the chassis is powered off before connecting. The 0.70 in height profile is low enough for most full-tower workstation chassis, but verify clearance against any card shroud or adjacent bracket. Country of origin is CN; weight is 0.10 lb.
