Questions & Answers
Q
What is the capacity and form factor of the HP 876181-B21 memory module?
A
The HP 876181-B21 module delivers 8 GB of DDR4 registered ECC memory in a 288-pin RDIMM form factor.
Q
What type of memory is the HP 876181-B21?
A
The HP 876181-B21 is DDR4 Registered (RDIMM) memory with Error-Correcting Code (ECC) for server environments.
Q
What is the clock speed of the HP 876181-B21 module?
A
This module operates at a native 2666 MHz frequency to ensure high data throughput and system responsiveness.
Q
What does 2Rx8 mean in HP 876181-B21 specifications?
A
2Rx8 indicates a dual-rank memory configuration with eight data bits per chip, optimizing density and performance.
Q
Which HP servers support the 876181-B21 DDR4 RDIMM?
A
HP ProLiant Gen9 and Gen10 series (e.g., DL360, DL380, ML350) fully support the 876181-B21 module.
Q
Can I mix the 876181-B21 module with other memory types?
A
Mixing RDIMMs and UDIMMs is not supported; for best results, install identical HP registered ECC modules in matched ranks.
Q
How do I install the HP 876181-B21 DIMM?
A
Power off the server, align the DIMM notch to the slot key, press down evenly until the latches click, then power on.
Q
What are the benefits of ECC memory in the 876181-B21 module?
A
ECC detects and corrects single-bit errors in real time, reducing data corruption and enhancing system reliability.
Q
Is the HP 876181-B21 hot-pluggable?
A
No. Registered ECC RDIMMs must be installed with the server powered off to ensure proper detection and initialization.
Q
How does registered memory differ from unbuffered memory?
A
Registered (buffered) DIMMs include a register that reduces electrical load on the memory controller, enabling higher densities and stability.
Q

A
HP offers a limited lifetime warranty for genuine HP memory when used in compatible HP systems.
Q
How does 2666 MHz memory improve server performance?
A
Higher clock speeds increase data transfer rates between CPU and memory, reducing latency for compute-intensive workloads.
Q
Is 2666 MHz the native or maximum supported speed?
A
2666 MHz is the native JEDEC-rated speed of the module; actual speed may vary based on server BIOS and CPU support.
Q
Can the HP 876181-B21 work with Intel and AMD platforms?
