Compatibility is restricted to specific Gigabyte boards supporting the CXL standard only
Gigabyte’s AI Top CXL R5X4 quietly expands RAM capacity for demanding workstation workloads
The card supports four DDR5 RDIMM ECC modules totaling 512GB of memory
PCIe 5.0 x16 connection ensures direct CPU access for improved performance
Gigabyte has quietly introduced the AI Top CXL R5X4 PCIe adapter, a card designed to provide large-scale memory expansion for workstation motherboards.
Unlike earlier Compute Express Link (CXL) solutions that were mainly limited to server hardware, this model targets high-performance desktop systems such as the TRX50 AI TOP and W790 AI TOP.
The card connects directly to the CPU via a PCIe 5.0 x16 slot, enabling up to 512GB of additional DDR5 registered memory.Design and compatibility considerations
According to Gigabyte, this card will accelerate demanding workloads, particularly AI training tasks that require vast amounts of memory to process large datasets locally.
