Design Features

• Dual Rank x4 organization for enhanced memory interleaving and performance.
• Registered (buffered) design reduces electrical load on the memory controller, enabling higher capacity per channel.
• ECC support detects and corrects single-bit memory errors, reducing system downtime.
• No heatsink installed, suitable for servers with active chassis cooling.
• Operates at standard 1.2 V DDR4 voltage for energy-efficient deployment.

Application Area

This memory kit is suited for HPE ProLiant and other x86 enterprise servers deployed in data centers across Poland and CEE, where it supports virtualization clusters, in-memory databases, and ERP systems. It is also used in high-availability configurations requiring registered ECC memory for data integrity under continuous operation. The 32 GB density per module helps optimize server memory footprint without exceeding power or thermal budgets.
