64 GB DDR4 2666 ECC RDIMM

This module delivers 64 GB of DDR4 2666 memory in a single registered DIMM. It targets servers and workstations that require error-correcting code for data integrity. The 2S2Rx4 organisation provides high density for multi-socket platforms. Builders expanding memory capacity in compatible systems will benefit from the added bandwidth.

Registered DIMM for DDR4 platforms

The 288-pin form factor fits standard DDR4 RDIMM slots on server and workstation motherboards. Registered buffering reduces electrical load on the memory controller, allowing larger populations per channel. ECC capability corrects single-bit errors to maintain uptime. Verify the system's qualified vendor list before installation to ensure proper operation.

Sustained load stability at 1.2 V

Operating at 1.20 V with CL19 latency, the module maintains consistent throughput during extended compute tasks. Major-brand chips undergo validation testing to meet server-grade reliability standards. The registered design helps signal integrity under continuous heavy traffic. Thermal characteristics remain within DDR4 specifications for densely populated configurations.

商品問答

Does the CL19 latency become a bottleneck when the 64GB module runs at DDR4 2666 for long periods?

CL19 is the rated CAS latency at 2666 MHz; sustained throughput stays at PC4-21300 as long as the system keeps the module at its 1.20 V specification.

How much heat does the registered 4Rx4 DIMM produce when it operates continuously at 1.20 V in a server chassis?

The module runs at standard DDR4 1.20 V with registered buffering, so thermal output matches typical 64 GB RDIMM levels for 288-pin DDR4 2666 operation.

What motherboard feature must already be present for this 288-pin ECC RDIMM to function?

The board must provide a DDR4 288-pin RDIMM slot with ECC support and a memory controller that accepts 2S2Rx4 (4Rx4) registered modules.
