Frequently Asked Questions

What motherboards are compatible with this memory?

The Kingston Server Premier DDR4 16GB 2666MT/s ECC UDIMM ECC UDIMM — KSM26ES8/16HC 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.

Do I need to enable ECC UDIMM in BIOS?

Yes. Out of the box, DDR4 memory runs at JEDEC default speed (typically 2133 MT/s). To achieve the rated 2,666 MT/s with CL19-19-19-42 timings, enable ECC UDIMM in your motherboard BIOS. This is a one-click setting in the memory overclocking section.

Can I add more memory later?

Yes, the Kingston Server Premier DDR4 16GB 2666MT/s ECC UDIMM ECC UDIMM — KSM26ES8/16HC 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 Kingston Server Premier DDR4 16GB 2666MT/s ECC UDIMM ECC UDIMM — KSM26ES8/16HC 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 Kingston Server Premier DDR4 16GB 2666MT/s ECC UDIMM ECC UDIMM — KSM26ES8/16HC comes with a Limited Lifetime warranty from Kingston.
