Frequently Asked Questions

What motherboards are compatible with this memory?

The Synology 32GB DDR4-3200 ECC Registered DIMM (D4ER03-32G) 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 Synology 32GB DDR4-3200 ECC Registered DIMM (D4ER03-32G) runs at 3,200 MT/s. This is a JEDEC standard speed that works automatically without BIOS configuration.

Can I add more memory later?

Yes, the Synology 32GB DDR4-3200 ECC Registered DIMM (D4ER03-32G) is a single 32GB 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 Synology 32GB DDR4-3200 ECC Registered DIMM (D4ER03-32G) 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.

What warranty does this memory come with?

The Synology 32GB DDR4-3200 ECC Registered DIMM (D4ER03-32G) comes with a 5 Years warranty from Synology.
