Frequently Asked Questions
What is the difference between LRDIMM and RDIMM memory?
LRDIMM (Load-Reduced DIMM) modules use a buffer to reduce electrical load on the memory controller, enabling higher memory density and better performance in multi-socket server configurations compared to standard RDIMM modules. The AddOn 128GB DDR4-3200 LRDIMM supports more memory capacity per server slot.
Is this 128GB memory module compatible with my HP server?
The AddOn P19047-K21-AM is specifically designed for HP ProLiant and HP Synergy servers that support DDR4-3200 ECC LRDIMM memory. Check your server's memory specifications to confirm compatibility with 4Rx4 configuration and 1.2V operation.
Why choose ECC memory for server environments?
ECC (Error-Correcting Code) memory automatically detects and corrects single-bit errors in real-time, preventing data corruption and system crashes. For production servers running databases, virtualization, or critical applications, ECC DDR4-3200 memory is essential for maintaining uptime and data integrity.
What workloads benefit most from 128GB memory capacity?
Large-scale virtualization, in-memory databases, data analytics, machine learning, and high-performance computing applications benefit significantly from 128GB memory modules. The AddOn LRDIMM enables server consolidation and reduces infrastructure costs.
