Ideal laptop memory upgrade

This 8GB DDR4 module targets owners of compatible laptops, notebooks, or all-in-one systems seeking a straightforward capacity increase. The 260-pin SO-DIMM form factor fits standard DDR4 slots in portable devices. It serves as a direct replacement for the Samsung M471A1G43EB1-CRC part number. Buyers who need ECC error correction or registered buffering should look elsewhere.

Standard SO-DIMM build quality

The unbuffered, non-ECC stick uses a conventional green PCB with gold-edge contacts that seat firmly in 260-pin sockets. Operating at the DDR4 standard voltage of 1.20V, it draws typical power without requiring special cooling or BIOS voltage adjustments. Single-module design leaves a second slot free for future expansion if the chassis permits. Systems limited to lower DDR4 speeds or proprietary form factors will not accept this module.

Speed and latency define fit

Rated at 2400MHz (PC4-19200) with a CAS latency of CL17, the module delivers baseline DDR4 bandwidth for everyday workloads. The motherboard will automatically negotiate the highest common speed supported by the CPU and chipset. Buyers whose platforms require faster JEDEC profiles or tighter timings for specific applications will not gain the intended benefit from this specification.

Questions about this item

What DDR4 standard and speed does this 260-pin SODIMM run at?

It operates at DDR4 2400 MHz, labelled PC4-19200, which is the maximum data rate the JEDEC specification defines for this module.

What physical slot and notch position does the 260-pin SO-DIMM require?

The module uses the standard DDR4 SO-DIMM key notch, so it fits any laptop or all-in-one socket wired for 260-pin DDR4 memory.

How do I seat the SODIMM correctly, and what step do people often miss?

Slide the module into the slot until the gold contacts are fully hidden, then press down evenly until the side retention clips snap into the notches on each edge.
