SK Hynix 32 GB DDR4-2933 MHz PC4-23400 CL21 Registered ECC Server Memory Module (RDIMM)

The SK Hynix HMA84GR7CJR4N-WM is a high-performance 32 GB DDR4 registered ECC memory module designed for demanding server and workstation environments. Built with industry-leading SK Hynix technology, this module delivers reliable, error-corrected performance at 2933 MHz with a data rate of PC4-23400. Its registered (RDIMM) architecture ensures stability and scalability in multi-module configurations, making it an ideal choice for data centers, enterprise servers, and professional workstations.

Advantages

This memory module offers exceptional reliability and performance for mission-critical applications. With ECC (Error-Correcting Code) support, it detects and corrects single-bit memory errors, preventing data corruption and system crashes. The registered design reduces electrical load on the memory controller, allowing for larger memory capacities and improved signal integrity. Operating at 1.2V, it balances power efficiency with high-speed operation, contributing to lower overall system power consumption.

Suitable for

• Enterprise servers requiring high-capacity, error-corrected memory
• Virtualization platforms running multiple virtual machines
• Database servers handling large transactional workloads
• High-performance computing (HPC) clusters
• Workstations for CAD, video editing, and scientific simulations
