Frequently Asked Questions

What motherboards are compatible with this memory?

The GOODRAM UDIMM ECC DDR4 16GB 2666MHz 2Rx8 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 GOODRAM UDIMM ECC DDR4 16GB 2666MHz 2Rx8 runs at 2,666 MT/s with CL19 timings. This is a JEDEC standard speed that works automatically without BIOS configuration.

Can I add more memory later?

Yes, the GOODRAM UDIMM ECC DDR4 16GB 2666MHz 2Rx8 is a single 16GB 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 GOODRAM UDIMM ECC DDR4 16GB 2666MHz 2Rx8 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 GOODRAM UDIMM ECC DDR4 16GB 2666MHz 2Rx8 comes with a Lifetime warranty from GOODRAM.
