Micron MTC40F2046S1RC48BA1 DDR5 64GB (1x64GB) 4800MHz RDIMM ECC Server Memory For Sale

The Micron MTC40F2046S1RC48BA1 is a 64GB DDR5 registered memory module engineered for server and workstation platforms that demand high-density, error-corrected capacity in a single stick. Built to the DDR5-4800 standard, it operates at PC5-38400 bandwidth and communicates with the host controller through an onboard registering clock driver, a design that buffers command and address signals so a board can support far more total memory per channel than an unbuffered module allows. The module uses a 2Rx4 dual-rank x4 organization across 288 pins, giving the memory controller two independent ranks to interleave requests against for improved throughput under multi-threaded workloads. On-die ECC and module-level ECC work together to detect and correct single-bit errors during operation, a feature that matters most in always-on infrastructure where an uncorrected bit flip can corrupt a running process. The module runs at a nominal 1.1V, in line with the JEDEC DDR5 power specification, which lowers per-module energy draw even as density and bandwidth both increase. A CAS latency of CL40 keeps access timing tight relative to the data rate, and the commercial-temperature-rated packaging suits continuous operation inside densely populated server chassis. Micron manufactures the DRAM die and assembles the module in-house, keeping the bill of materials consistent from unit to unit. This part serves as a drop-in upgrade for compatible server platforms that call for registered DDR5-4800 memory, and it is commonly paired with matching modules across a channel set to maximize bandwidth.

Key Features:

• Registered Memory Design: The onboard registering clock driver buffers command and address signals, letting compatible boards support higher total channel density.
• High Speed Data Rate: Rated for DDR5-4800 operation with PC5-38400 bandwidth, delivering strong sustained throughput for demanding server memory channels.
• Dual Rank Organization: A 2Rx4 configuration across 288 pins lets the memory controller interleave read and write requests between two independent ranks.
• Error Correcting Capability: Module level ECC detects and corrects single bit errors automatically, protecting data integrity in continuous server operation.
• Efficient Power Design: Operating at a nominal 1.1V with CL40 timing, the module balances low energy draw against tight access latency for its data rate.
