The Crucial CT32G56C46U5T is a 32GB DDR5-5600 unbuffered DIMM (UDIMM) engineered for high-performance desktop systems, entry-level workstations, and client platforms. Operating at JEDEC-standard 1.1V with CL46 latency, it delivers data transfer rates up to 44.8 GB/s per channel. Utilizing Micron DRAM dies, this dual-rank module provides high density and improved memory bandwidth for intensive multitasking and professional productivity workflows.
The CT32G56C46U5T is built on DDR5 SDRAM architecture featuring dual independent 32-bit subchannels per module, which improves memory access efficiency and bus concurrency compared to legacy DDR4. It features a 2Rx8 (dual-rank, x8 chip width) topology populated with sixteen 16Gb Micron DRAM monolithic dies. Unlike registered enterprise server memory (RDIMMs), this unbuffered DIMM lacks a Registering Clock Driver (RCD) or data buffers, with commands and addresses routed directly from the host memory controller to the DRAM dies.
DDR5 UDIMMs migrate voltage regulation from the motherboard directly onto the module via an onboard Power Management IC (PMIC) and an integrated SPD Hub with thermal sensing, receiving a 5V input rail and regulating it to 1.1V VDD, VDDQ, and 1.8V VPP. While the module incorporates JEDEC-mandated on-die ECC (ODECC) for internal DRAM bit error correction within the die array, it is a non-ECC module lacking sideband parity bits (no bus-level ECC). Decoding the Crucial part number: 'CT' designates Crucial Technology, '32G' represents 32GB density, '56' indicates 5600 MT/s speed, 'C46' indicates CAS latency 46, 'U' specifies UDIMM form factor, and '5' denotes DDR5 technology.
Always verify against your server's qualified vendor list (QVL).
No. While CT32G56C46U5T includes JEDEC standard on-die ECC to mitigate internal cell defects, it does not feature sideband bus-level ECC (it is a non-ECC UDIMM) and cannot correct transmission errors across the memory bus.
No. UDIMMs and RDIMMs are electrically and architecturally incompatible. Enterprise servers that mandate DDR5 RDIMMs will not boot with unbuffered memory installed, and UDIMMs cannot be mixed with RDIMMs.
The module follows standard JEDEC DDR5-5600 timings of 46-45-45 at 1.1V VDD/VDDQ, governed directly by the on-module PMIC without requiring custom XMP or EXPO overvolting.
