Frequently Asked Questions

What is the difference between SO-DIMM and standard DIMM?

SO-DIMM (Small Outline DIMM) is a compact memory module form factor used in laptops, small form factor servers, and embedded systems. It uses 262 pins for DDR5 vs the 288 pins of standard DDR5 DIMMs and is not interchangeable with standard DIMM slots.

Is the M426R4GA3BB0-CQK compatible with standard desktop or server motherboards?

No. The M426R4GA3BB0-CQK uses the 262-pin SO-DIMM form factor, which is only compatible with platforms designed for SO-DIMM memory. Standard desktop and server motherboards use 288-pin DIMM slots.

Does DDR5 SO-DIMM support ECC?

Yes, the M426R4GA3BB0-CQK is an ECC Unbuffered SO-DIMM, providing error-correcting code memory protection for platforms that support DDR5 ECC SO-DIMM.

The Samsung M426R4GA3BB0-CQK 32GB DDR5-4800 ECC Unbuffered SO-DIMM delivers next-generation DDR5 memory performance with ECC data integrity in a compact form factor. Order today for genuine Samsung DDR5 SO-DIMM quality for compact server and workstation platforms.
