MS33-AR1 Gigabyte

High-Density E-ATX Server Motherboard featuring PCIe Gen5 expansion and DDR5 bandwidth with the MS33-AR1 Gigabyte

The MS33-AR1 Gigabyte is an E-ATX server motherboard designed around a single-socket Intel Xeon Scalable 4th/5th Gen platform (LGA4677) on the Intel C741 chipset, targeting balanced compute density for virtualisation and enterprise application stacks. With support for up to 350W CPUs, it enables high core-count configurations while maintaining a straightforward, serviceable node architecture for standard rack server builds.

For memory-bound workloads, MS33-AR1 Gigabyte implements an 8-channel DDR5 ECC RDIMM topology across 16 DIMM slots, scaling to 4TB capacity to sustain high concurrency and large in-memory datasets. Expansion is engineered for modern I/O: multiple PCIe 5.0 x16 and x8 slots provide lane-rich connectivity for high-speed NICs, HBAs, and accelerator-class add-in cards. Storage design separates fast and bulk tiers by combining NVMe via SlimSAS with broad SATA fan-out and a dedicated M.2 NVMe boot option, supporting flexible RAID/VROC-aligned deployments and clean separation of OS, cache, and data volumes.

Why Choose the MS33-AR1 Gigabyte?

The MS33-AR1 Gigabyte delivers an efficient density-to-performance profile for single-socket nodes by pairing current-generation Xeon compute with DDR5 bandwidth and PCIe Gen5 expansion headroom. MS33-AR1 Gigabyte is well suited to scalable fleet rollouts where predictable platform longevity, remote management, and consistent I/O topology simplify qualification, lifecycle operations, and incremental upgrades.

Gigabyte engineers this platform with an enterprise reliability focus, integrating IPMI/BMC management and security provisions to align with modern data centre operational standards. MS33-AR1 Gigabyte supports structured cabling via SlimSAS/MCIO and maintains clear expansion and storage zoning to streamline integration and maintenance.

Key Applications:

Virtualisation hosts
Enterprise databases
Software-defined storage nodes
High-throughput networking appliances
General-purpose private cloud compute

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your MS33-AR1 Gigabyte rollout requirements and the option to extend the warranty up to 6 years for additional security on your infrastructure investment.
