256 GB DDR4 3200 ECC UDIMM kit with eight 32 GB modules at CL22 and 1.2 V for Supermicro servers
This 256GB kit contains eight 32GB DDR4 3200 unbuffered ECC UDIMMs built for Supermicro servers and workstations. It targets IT professionals who need validated, high-capacity memory for mission-critical environments. Each module runs at 1.20V with a CL22 latency and a 2Rx8 organisation. The kit is designed for straightforward installation in compatible 288-pin slots.
The eight-module configuration delivers 256GB of registered-error-correcting capacity, allowing large virtualisation hosts, database servers or NAS appliances to keep more working sets in RAM. ECC protection corrects single-bit errors on the fly, reducing silent data corruption under sustained load. Headroom ends when all eight slots are populated; further expansion requires a platform with additional DIMM slots or higher-density modules.
The package supplies a matched set of eight 32GB UDIMMs, eliminating the need to source and validate individual sticks. Pre-tested modules reduce the risk of mixed-rank or timing mismatches that can destabilise a server. No heat spreaders are included, so airflow clearance follows the chassis and motherboard layout. The kit contains only the memory modules; no cables, software or additional accessories are bundled.

Mixing modules of different speeds, latencies, ranks or voltages can prevent the system from training memory correctly; for reliable operation populate all slots with identical 3200 CL22 2Rx8 1.2V kits.
Enter the system BIOS or UEFI and confirm the memory frequency reads 3200 MT/s, total capacity shows 256GB, and ECC status is reported as enabled or active.
The box contains only the eight 288-pin DDR4 ECC UDIMM modules; no heat spreaders, cables, tools or documentation are bundled.
