GIGABYTE MS33-AR1 Μητρική κάρτα Intel C741 LGA 4677 (Socket E) Extended ATX

The GIGABYTE MS33-AR1 motherboard supports Intel C741 processors in the LGA 4677 socket and is built for server-class workloads on an Extended ATX board. It accepts up to 16 DDR5 DIMMs for a maximum of 256 GB memory, provides multiple storage interfaces including SATA III and SlimSAS, and includes onboard Aspeed AST2600 graphics and Broadcom Gigabit Ethernet (BCM57416). The design targets PCIe Gen5 platforms and high-throughput accelerator and storage configurations to make use of the performance and AI acceleration features of 4th and 5th Gen Intel Xeon Scalable processors.

Advantages

The MS33-AR1 offers a server-optimized layout with extensive memory capacity, PCIe Gen5 readiness and broad storage connectivity including RAID 0/1/5/10 support. Integrated Aspeed AST2600 management graphics and Broadcom network controllers simplify remote management and reliable networking. Optional TPM 2.0 support provides hardware-based authentication and secure storage of keys and certificates when a TPM module is installed.

Suitable for

• Server and rack systems requiring high memory density
• AI/ML inference and data analytics using PCIe Gen5 accelerators
• Storage servers and virtualization with RAID configurations
• Remote management and out-of-band maintenance environments

How to use

Install a compatible Intel C741 processor into the LGA 4677 socket following standard server installation procedures and ESD precautions. Populate DDR5 DIMMs in matched pairs or as recommended by the motherboard manual to reach the desired memory capacity (up to 256 GB). Connect storage devices to the SATA III and SlimSAS ports and configure RAID through the firmware or OS-level tools as required. If remote management or hardware-based security is needed, install the optional TPM 2.0 module on the appropriate header and set up TPM in the system firmware.
