16GB DDR3L ECC RDIMM for Servers

This 16GB DDR3L 1600 ECC Registered DIMM targets administrators upgrading Hynix-compatible servers and workstations. The module delivers 16GB capacity at PC3L-12800 speed with CL11 latency. Error-correcting code and registered buffering suit multi-socket platforms requiring data integrity. It replaces Hynix HMT42GR7AFR4A-PB, HMT42GR7BFR4A-PB, HMT42GR7DFR4A-PB and HMT42GR7MFR4A-PB parts directly.

DDR3L 1.35V Registered Interface Limits

The DDR3L standard operates at 1.35V, lower than standard DDR3, so the platform must support low-voltage DIMMs. Registered signalling adds a clock cycle, which affects command timing compared with unbuffered memory. Maximum bus frequency is 1600 MT/s; the memory controller must be qualified for this speed with registered modules. Mixed-voltage populations are not supported by the DDR3L specification.

Compatibility Checks Before Ordering

Verify that your system board lists DDR3L 1600 ECC RDIMM 2Rx4 240-pin DIMMs on its qualified vendor list. Confirm the CPU memory controller supports registered low-voltage modules at this density. Ensure the BIOS revision enables ECC and registered operation for the target slots. Check that no slot population rules forbid 16GB dual-rank modules in your configuration.

Questions about this item

Should I choose the 16GB DDR3L 1600 ECC RDIMM 2Rx4 or a different capacity for my server?

This module provides a single 16GB stick at DDR3L 1600 with CL11 latency and 1.35V operation. Select it when your system requires a registered DIMM with 2Rx4 organisation and you need exactly 16GB per slot.

What does the 1600MHz speed rating deliver once the module is installed in a live server?

At DDR3L 1600 (PC3L-12800) the memory runs at 1600 MT/s with CL11 timing, giving the rated bandwidth for registered ECC workloads while operating at the low 1.35V voltage.

How does the DDR3L 240-pin RDIMM interface limit performance in practice?

The 240-pin DDR3L RDIMM interface caps the module at 1600 MT/s and 1.35V; the registered buffer adds one cycle of latency but allows the memory controller to drive larger capacities reliably.
