FAQ's
What servers are compatible with the 835958-B21 memory? The 835958-B21 memory module is compatible with HP servers that support DDR4 ECC Registered DIMMs. It is designed specifically for certain HP ProLiant server models requiring this memory type. What does ECC mean in this memory module? ECC stands for Error Correcting Code, a feature that detects and corrects single-bit memory errors to improve data integrity and system stability in server environments. Is the 835958-B21 memory a Registered DIMM? Yes, this module is a Registered DIMM (RDIMM), which includes a register to buffer memory commands, enhancing stability in multi-module server configurations. What is the significance of the 2666MHz speed? The 2666MHz speed indicates the operating frequency of the DDR4 memory, balancing performance and power consumption suitable for enterprise server workloads. What does the CL19 latency indicate? CL19 refers to the CAS latency, or the delay time between a command and data availability, measured in clock cycles. A CL19 latency is typical for this type of DDR4 memory module. Can this memory be used in non-HP servers? This memory module is designed for HP server systems; compatibility with non-HP servers depends on support for DDR4 ECC RDIMMs and may not be guaranteed.
