About the Crucial 256GB DDR5-5600 ECC MRDIMM CL46 1.1V (Multiplexed Rank)

```html

Crucial Multiplexed Rank MRDIMM with ECC for Intel Xeon 6 platforms — the CT256G56C46MR5 delivers enterprise-grade memory reliability and density for next-generation data center infrastructure. This 256GB DDR5-5600 module combines Crucial's trusted quality with the multiplexed rank architecture demanded by modern server deployments. Operating at DDR5-5600 (5600 MT/s) with CAS Latency CL46 and a low 1.1V operating voltage, this MRDIMM is engineered for Intel Xeon 6 (Granite Rapids) systems and other MRDIMM-capable server platforms. The 288-pin, 72-bit (64-bit data + 8-bit ECC) form factor integrates seamlessly into high-capacity memory configurations while maintaining tight thermal tolerances across the 0°C to 85°C operating range. RoHS compliance ensures environmental responsibility without compromising performance or reliability.

Data center infrastructure teams, storage architects, and IT procurement professionals standardizing on DDR5 server memory increasingly specify Crucial solutions for their proven stability and value. Organizations deploying Xeon 6–based systems benefit from the error-correcting code (ECC) functionality built into this module, which protects against silent data corruption in mission-critical workloads. The multiplexed rank configuration maximizes memory density per slot, allowing customers to achieve higher total capacity within physical space and power constraints. For enterprises running virtualization, analytics, databases, or high-availability services, the combination of 256GB capacity, ECC protection, and Crucial's manufacturing heritage represents a defensible choice against emerging memory demands.
