High-Capacity DDR5 Server Memory
This is a 256GB DDR5 ECC registered DIMM built for server and workstation platforms. It operates at 4800MHz with a CAS latency of 40 and runs at the standard 1.10V. The module uses a Samsung chipset and a 288-pin form factor for high-density memory expansion.
Suited For High-Density Registered Slots
It fits systems that require registered ECC DDR5 modules with an 8Rx4 3DS/TSV rank configuration. Builders using unbuffered memory, non-ECC platforms, or motherboards limited to lower capacities per slot cannot use this module.
Key Spec Is 256GB Registered ECC DDR5
The single deciding factor is whether your platform supports a 256GB DDR5 4800 registered ECC DIMM with a 2S4Rx4 (8Rx4 EC8) organisation. Verify the qualified vendor list and maximum rank support before purchasing.

คำถามเกี่ยวกับสินค้านี้
Will the 288-pin DDR5 RDIMM fit my server's DIMM slots?
This module uses the standard 288-pin DDR5 DIMM form factor. Verify your motherboard supports DDR5 RDIMMs before installing.
How do I install this 256GB ECC RDIMM correctly?
Power down the server, open the chassis, align the module notch with the slot key, press firmly until the retention clips click. A common error is not seating both ends evenly.
When should I replace this 256GB DDR5 4800 module?
Replace if memory diagnostics report uncorrectable ECC errors, the system fails to POST with the module installed, or capacity no longer meets workload demands.
