8GB DDR4 2133MHz SODIMM Upgrade

This A-Tech module provides an 8GB DDR4 2133MHz (PC4-17000) memory upgrade for compatible laptops, notebooks and all-in-one systems. It uses a standard 260-pin SO-DIMM form factor and operates at the DDR4 standard voltage of 1.20V. The unbuffered, non-ECC design features major brand chips and carries CAS latency of CL15.

Suits owners replacing Dell parts.

The module is validated as a direct replacement for several Dell part numbers including 370-ACHS, A8860719, SNPTD3KXC/8G, SNP09WKPC/8G, TD3KX, A8547953, 370-ADIB, A8718897 and 370-ACDD. It is designed for AMD and Intel platforms that accept standard unbuffered SODIMMs. Systems requiring ECC, registered or buffered memory cannot use this module.

Deciding spec: 260-pin DDR4 SO-DIMM at 2133MHz

The single specification that determines fit is the 260-pin DDR4 SO-DIMM interface running at 2133MHz (PC4-17000). Your system must support this exact generation, pin count and speed; other DDR generations or pin layouts are physically and electrically incompatible. Verify your device documentation for supported memory specifications before purchasing.

Questions about this item

How do I install the 260-pin DDR4 SODIMM, and what step do people often get wrong?

Align the notch on the module with the slot key, insert at an angle, then press down firmly until both side clips click. The step people miss is pushing hard enough to fully seat the clips.

What maintenance or replacement will this 8GB DDR4 2133MHz module need later?

No routine maintenance is required. Keep the laptop vents clear so the module stays near its 1.20V operating temperature. Replace only if a memory test reports errors or you need more capacity.

What limit appears first when this CL15 1.20V DDR4 SODIMM runs sustained workloads?

The CL15 latency at 2133 MHz sets the bandwidth ceiling. Under continuous load the memory controller hits that throughput limit before voltage or thermal throttling becomes a factor.
