Frequently Asked Questions

What motherboards are compatible with this memory?

The Kingston ValueRAM DDR4 4GB 2666MT/s SODIMM JEDEC — KVR26S19S6/4 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. This SO-DIMM module fits laptops and compact PCs with DDR4 SO-DIMM slots.

Do I need to enable JEDEC 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 JEDEC in your motherboard BIOS. This is a one-click setting in the memory overclocking section.

Can I add more memory later?
