Certified 16GB DDR4 ECC RDIMM

This 16GB DDR4 3200 module is built for servers and workstations that require registered ECC memory. It operates at 1.20V with a CAS latency of CL22 and uses a 2Rx8 dual-rank layout. The 288-pin RDIMM form factor fits standard DDR4 server slots.

Supermicro certified compatibility

The module carries Supermicro certification for part numbers MEM-DR416L-HL01-ER32 and MEM-DR416LD-ER32. This validation means the stick has been tested for reliable operation in qualified Supermicro platforms. Hynix DRAM chips provide the underlying memory array.

Verify registered ECC support

Confirm your motherboard accepts registered ECC DDR4 RDIMMs before ordering. Consumer desktop boards and many unbuffered server platforms will not recognise this module. Check the system manual for supported speeds, ranks and maximum capacity per slot.

Questions about this item

Will the 1.20V DDR4 modules need any voltage adjustment or replacement after extended server use?

The 1.20V DDR4 modules run at standard JEDEC voltage and require no adjustment; they are built for continuous server operation and carry a lifetime warranty.

What limit appears first when the 2Rx8 registered ECC DIMMs run at 3200 MHz under sustained load?

The CL22 CAS latency at 3200 MHz is the primary timing constraint; the registered buffer and ECC logic maintain stability before thermal or power limits are reached.

How much heat and noise do the 288-pin RDIMMs generate when the server runs all day?

DDR4 RDIMMs are passive components with no moving parts; they add minimal heat and zero noise, while the 1.20V rating keeps power draw low.
