NEMIX RAM
16GB DDR5 4800 ECC unbuffered UDIMM with 1Rx8 organisation, CAS 40 latency and 1.1V operation
This 16 GB unbuffered DIMM runs at DDR5 4800 with CAS 40 latency and 1.1 V operation. It provides error-correcting code protection for data integrity in compatible platforms. The module uses a single-rank 1Rx8 organisation based on major OEM DRAM chips.
Systems that require registered or load-reduced DIMMs cannot use this unbuffered module. Builders targeting higher speeds or lower latencies than 4800 MT/s and CL40 should look at alternative specifications. Non-ECC platforms will not utilise the error-correction capability.
The PC5-38400 rating confirms 4800 MT/s transfer rate at 1.1 volts. This single specification determines whether the module matches the memory controller requirements of the target system. Verify platform support for DDR5 4800 ECC UDIMM before purchase.

This module uses the standard 288-pin DDR5 UDIMM form factor. It fits any desktop or workstation board with DDR5 UDIMM slots keyed for 1.1 V operation.
Align the notch with the slot key, press straight down until both retention clips click. A common error is stopping at the first click; both clips must latch to make full contact.
DDR5 modules have no moving parts and no scheduled replacement interval. Replace only if memory diagnostics report correctable ECC errors rising above the platform threshold or a module fails completely.
