Certified Supermicro laptop memory

This 4GB DDR4 SODIMM carries Supermicro certification and uses Samsung components. It runs at 2666MHz with CL19 timing and operates at the standard 1.20V. The unbuffered non-ECC module fits 260-pin slots in compatible Supermicro systems.

Suited for specific Supermicro notebooks

It matches the MEM-DR440L-SL01-SO26 part number exactly, so owners of those validated platforms can install it with confidence. Builders using other laptop brands or desktop motherboards should verify their own memory specifications before purchasing.

Tested modules with lifetime backing

Every stick undergoes quality-assurance testing to confirm reliable operation. A lifetime warranty and US-based technical support are included, giving long-term assurance without extra software or accessories.

Perguntas sobre este artigo

My laptop only has one SO-DIMM slot — can I use this single 4GB module on its own?

Yes, this is a single 4GB stick so it works alone in a lone slot.

I have an older DDR4 2666 CL19 stick already installed — will this CL19 module run at the same timings?

Both are CL19 at 2666 MHz, so the memory controller will apply identical timings to each.

After fitting the module, how can I confirm it is running at 2666 MHz and 1.20V?

Open Task Manager or CPU-Z — the SPD tab shows 2666 MT/s and 1.20 V when the stick is seated correctly.
