HPE P36999-B21 16GB DDR5 4800MHz RDIMM – In Dubai
Overview :
The HPE P36999-B21 is a 16GB DDR5 registered DIMM (RDIMM) designed for HPE ProLiant Gen12 servers. It is deployed by data center engineers and IT administrators to enhance system memory capacity with high bandwidth, low latency, and ECC reliability for virtualization, analytics, and enterprise workloads.
Operating at 4800 MT/s, this module delivers consistent memory throughput while incorporating ECC (Error-Correcting Code) to detect and correct memory errors in real time. Its registered architecture buffers command and address signals, reducing electrical load on the memory controller and allowing higher DIMM populations across multi-channel memory configurations.
This module is intended for rack and tower servers in enterprise data centers, private clouds, and high-density compute clusters. It is ideal for workloads requiring predictable memory performance, including virtual machine hosting, in-memory database processing, and analytics platforms.
Integration aligns with HPE SmartMemory validation, ensuring compatibility with supported ProLiant Gen12 platforms. Multi-channel configurations are supported for optimized throughput and system stability under sustained heavy workloads.
In practical deployment, the P36999-B21 expands server memory capacity, enabling higher VM density and improved application performance without increasing server count. It is not suitable for desktop PCs or platforms that do not support DDR5 ECC registered memory.
Typical Deployment Scenarios :
• Virtualization hosts with high memory bandwidth requirements
• In-memory database and analytics workloads
• High-performance computing nodes
• HPE ProLiant DDR5 memory expansion projects
• Private cloud infrastructure optimization
