Frequently Asked Questions

What motherboards are compatible with this memory?

The HP 8GB (1x8GB) DDR4-2933 ECC Registered Memory (5YZ56AA) requires a DDR4-compatible motherboard. Compatible platforms include AMD AM4 (B550, X570, B450, etc.) and Intel LGA 1700 (B660, Z690) or LGA 1200 (B560, Z590). DDR4 is NOT compatible with DDR5 slots — they use different pin configurations.

What speed does this memory run at?

The HP 8GB (1x8GB) DDR4-2933 ECC Registered Memory (5YZ56AA) runs at 2,933 MT/s with CL21 timings. This is a JEDEC standard speed that works automatically without BIOS configuration.

Can I add more memory later?

Yes, the HP 8GB (1x8GB) DDR4-2933 ECC Registered Memory (5YZ56AA) is a single 8GB module. You can add additional compatible DDR4 RDIMM modules to populate empty slots. For best performance, use matched modules of the same speed and capacity to enable dual-channel mode.

Does this memory support ECC error correction?

Yes, the HP 8GB (1x8GB) DDR4-2933 ECC Registered Memory (5YZ56AA) includes ECC (Error-Correcting Code) support, which detects and corrects single-bit memory errors. This is essential for servers, workstations, and mission-critical applications where data integrity is paramount.

Where can I find technical support?

Visit the HPE support website for compatibility tools, firmware updates, and technical documentation for the HP 8GB (1x8GB) DDR4-2933 ECC Registered Memory (5YZ56AA).
