Frequently Asked Questions

What motherboards are compatible with this memory?

The Synology 8GB DDR4-3200 ECC Unbuffered DIMM (D4EU02-8G) 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 8GB DDR4-3200 ECC Unbuffered DIMM (D4EU02-8G) runs at 3,200 MT/s with CL22 timings. This is a JEDEC standard speed that works automatically without BIOS configuration.

Can I add more memory later?

Yes, the Synology 8GB DDR4-3200 ECC Unbuffered DIMM (D4EU02-8G) is a single 8GB module. You can add additional compatible DDR4 ECC UDIMM 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 8GB DDR4-3200 ECC Unbuffered DIMM (D4EU02-8G) 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 8GB DDR4-3200 ECC Unbuffered DIMM (D4EU02-8G) comes with a 5 Years warranty from Synology.
