Frequently Asked Questions

What motherboards are compatible with this memory?

The Kingston Server Premier DDR4 32GB 2666MT/s RDIMM RDIMM — KSM26RD4/32HDI 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 RDIMM 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 RDIMM 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 32GB 2666MT/s RDIMM RDIMM — KSM26RD4/32HDI 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 Kingston Server Premier DDR4 32GB 2666MT/s RDIMM RDIMM — KSM26RD4/32HDI 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 32GB 2666MT/s RDIMM RDIMM — KSM26RD4/32HDI comes with a Limited Lifetime warranty from Kingston.
