FAQ
What is the difference between Registered and Unbuffered memory?
Registered memory (RDIMM) includes a register between the memory modules and controller to buffer signals, reducing electrical load on the memory controller. This allows support for more modules per channel compared to unbuffered memory (UDIMM), making Registered memory better suited for server environments with high memory capacity requirements.
How does ECC memory protect my server data?
ECC (Error-Correcting Code) memory detects and corrects single-bit errors that can occur during data storage or transmission. This protection maintains data integrity without system crashes or data corruption, which is particularly important for servers running critical applications, databases, or virtualization workloads where data accuracy is essential.
What does quad-rank memory mean?
Quad-rank memory divides the memory module into four independent sections that can be accessed separately. This architecture improves memory controller efficiency by allowing more concurrent access operations compared to single or dual-rank modules. The quad-rank design in this 32GB module optimizes memory bank utilization for better performance in memory-intensive server applications.
Which HP servers are compatible with this memory module?
This module is compatible with HP ProLiant BL685c Gen7 (G7) servers using part number 518878-B21 and HP ProLiant DL585 Gen7 (G7) servers using part number 601362-001. It maintains the same specifications as the HP 627810-B21 module it replaces, ensuring proper operation in these specific server platforms.
What are the advantages of 1.35V memory voltage?
The 1.35V operating voltage reduces power consumption compared to standard 1.5V DDR3 memory, which lowers heat generation and improves energy efficiency. This is particularly beneficial in server environments where multiple memory modules are installed, as the reduced power draw contributes to lower overall system power requirements and cooling needs.
What does CL7 latency mean for server performance?
CL7 (CAS Latency 7) indicates the memory module requires 7 clock cycles between receiving a column address and returning the first bit of data. Lower latency numbers generally mean faster response times for memory access requests. The CL7 rating on this module provides balanced performance for server workloads where both bandwidth and responsiveness are important considerations.
