NEMIX RAM
A 32 GB DDR4 3200 ECC registered DIMM with CL22 latency and 1.2 V operation for compatible Dell servers
This 32GB DDR4 ECC RDIMM is built for Dell servers and workstations that require registered memory. It suits IT professionals upgrading compatible Dell systems for virtualization, database or enterprise workloads. The module is not intended for consumer desktops or laptops that use unbuffered DIMMs. Buyers who need non-ECC or SODIMM formats should look elsewhere.
Operating at 1.2V standard DDR4 voltage, the module draws minimal power and produces no audible noise because it has no fan or moving parts. Passive cooling relies on system airflow across the bare PCB as no heat spreader is fitted. Typical server chassis airflow is sufficient for normal registered DIMM thermals. The component adds negligible thermal load to the memory subsystem.
The single specification that decides fitment is the registered ECC RDIMM design with 288-pin DDR4 interface and CL22 latency at 3200 MT/s. Only platforms that explicitly support registered ECC DDR4 DIMMs can use this module. Systems requiring unbuffered or non-ECC memory will not post with this part installed. Verify the Dell service tag or motherboard manual before purchase.

Power down the Dell server, open the chassis, align the notch on the module with the slot key, press firmly until both clips lock, then enable ECC in the BIOS — skipping the BIOS step leaves error correction inactive.
The module has no moving parts and no heat spreader; it requires no scheduled maintenance. Replace it only if memory diagnostics report uncorrectable errors or if a capacity upgrade is required.
The CAS latency of 22 cycles at 3200 MT/s sets the baseline response time; under continuous load the memory controller will hit this timing ceiling before bandwidth or voltage limits become a factor.
