System-Specific 256GB DDR4 Kit

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.

256GB Capacity with ECC Headroom

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.

Eight-Module Kit Simplifies Deployment

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.

Questions about this item

Will these 256GB DDR4 3200 CL22 ECC UDIMM modules run alongside my existing DDR4 ECC UDIMM sticks?

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.

How can I verify the 8x32GB kit is recognised at 3200MHz with ECC active after installation?

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.

Does the ME25600-328K8 package include anything besides the eight 32GB UDIMMs?

The box contains only the eight 288-pin DDR4 ECC UDIMM modules; no heat spreaders, cables, tools or documentation are bundled.
