Server-ready DDR4 ECC RDIMM
This 8 GB DDR4 registered module runs at 2133 MT/s with CL15 latency and 1.2 V operation. It uses a 1Rx4 organisation and 288-pin form factor for server and workstation platforms that require ECC protection. The part is validated for system-specific compatibility and is not intended for desktop or laptop PCs.
Thermals noise and power draw
Standard DDR4 voltage of 1.2 V keeps power consumption low for dense server configurations. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity across populated channels. No active cooling is required on the module itself under normal airflow conditions.
Upgrade path and value
This module replaces a failed or missing stick in qualified server boards that demand registered ECC memory at 2133 speed. The jump is worth it when expanding capacity within the same speed grade or when a platform specifically lists this part number as supported. It does not suit consumer desktop or laptop upgrades.

이 상품에 대한 질문
How do I install this 288-pin DDR4 RDIMM and which step is often missed?
Align the notch with the slot key, press firmly until both latches click, and verify the module is fully seated — partial insertion is the common error that prevents POST.
What maintenance or replacement will this 8GB 1Rx4 module need over time?
No routine maintenance is required; if errors appear, run a memory diagnostic and replace the individual stick if it fails, since ECC corrects single-bit faults but cannot repair a defective chip.
What limit appears first when this CL15 1.20V registered memory runs under sustained load?
The registered buffer adds one cycle of latency, so sustained throughput is capped by the 2133 MT/s data rate and CL15 timing rather than thermal or voltage headroom.
