16 GB DDR4 2666 ECC UDIMM
This 16 GB DDR4 2666 ECC unbuffered module targets servers and workstations that require error-correcting memory. The 2Rx8 organisation and CL11 timing deliver 16 GB of registered-grade reliability in a standard UDIMM form factor. Supermicro certification confirms validation on qualified platforms.
Upgrade from non-ECC or lower-capacity DDR4
Replacing non-ECC modules adds single-bit error correction for data integrity in critical workloads. Moving from 8 GB sticks doubles capacity per slot without changing voltage or pin layout. The jump is worth it when ECC support is mandatory and slot count is limited.
Fits 288-pin DDR4 slots at 1.20 V
The module installs in any 288-pin DDR4 UDIMM socket that accepts 1.20 V unbuffered ECC memory. No extra cooling or register buffer is required, leaving headroom for additional DIMMs. Builders needing registered RDIMMs or higher speeds must select a different part.

שאלות על הפריט הזה
Does this 288-pin DDR4 UDIMM fit a standard server memory slot?
Yes, the 288-pin DDR4 UDIMM form factor matches standard unbuffered server DIMM sockets.
What BIOS setting should I check when installing this CL19 ECC module?
Enable ECC support in the BIOS and verify the memory runs at 2666 MT/s with 1.20 V; a common mistake is leaving ECC disabled.
When should I consider replacing this 16 GB 2Rx8 kit?
Replace it if system logs report correctable ECC errors that increase over time or if the modules fail memory diagnostics.
