Gigabyte GA-X99-UD3-cr X99 4-Way SLI Motherboard Renewed

The Gigabyte GA-X99-UD3 is an ATX motherboard built on Intel's X99 chipset, designed for the LGA 2011-3 socket. This platform supports Intel's Haswell-E and Broadwell-E processors, including high-core-count chips like the Core i7-5960X and i7-6950X, as well as Xeon E5 v3/v4 workstation processors. The X99 chipset provides up to 40 PCIe 3.0 lanes from the CPU, which is what enables the board's headline feature: support for 4-way NVIDIA SLI and AMD CrossFireX multi-GPU configurations. This makes it relevant for 3D rendering, GPU compute, and other workloads that benefit from multiple graphics cards.

One distinction worth noting is that this board has 4 DIMM slots rather than the 8 slots found on many X99 competitors. While 4 slots still support a meaningful amount of DDR4 memory, it does reduce the maximum capacity and limits quad-channel memory to one DIMM per channel with no room for expansion. As a renewed product, this motherboard has been tested and verified to function correctly, but it is not a new unit — it may show signs of prior use and typically carries a seller warranty rather than Gigabyte's original coverage. For builders looking to assemble or upgrade an LGA 2011-3 system at a reduced cost, it remains a functional option on a platform that, while no longer current, still delivers strong multi-threaded and multi-GPU performance.
