NEMIX RAM
An 8 GB DDR4 3200 ECC unbuffered UDIMM with CL22 latency for SuperMicro R12SPD-A systems
This 8GB DDR4 3200 ECC unbuffered UDIMM is built for SuperMicro R12SPD-A systems that require error-correcting memory. It suits administrators upgrading servers or workstations where data integrity matters more than raw speed.
The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V. Throughput is limited by the DDR4 bus and the JEDEC timing; the board must support unbuffered ECC at this speed or it will down-clock.
The 288-pin UDIMM slots into standard DDR4 DIMM sockets without tools. Problems usually arise when mixing ranks or speeds, or when the BIOS does not enable ECC, causing the system to ignore the error-correction feature.
