8GB DDR4 SODIMM kit for laptop upgrades

This A-Tech kit supplies 8 GB of DDR4 memory in two 4 GB modules. It is intended for owners of laptops, notebooks or all-in-one PCs that accept 260-pin SO-DIMMs and need a straightforward capacity increase.

Dual-channel 260-pin modules at 1.2 V

The two unbuffered, non-ECC sticks are built to the standard DDR4 SODIMM form factor and run at the JEDEC 1.20 V voltage. Their 260-pin edge connector fits the SO-DIMM slots found in compatible portable systems, and the dual-channel packaging lets the memory controller interleave access across both modules.

Rated DDR4 2133 CL15 (PC4-17000)

The kit operates at 2133 MT/s with a CAS latency of 15, corresponding to the PC4-17000 designation. Systems that do not support DDR4 2133 SO-DIMM memory will not be able to use this kit.

Questions about this item

Does the DDR4 2133 speed cap at PC4-17000 bandwidth?

Yes, the kit is rated DDR4 2133 (PC4-17000), so the maximum theoretical throughput is 17,000 MB/s; the memory controller will not exceed that limit.

Will the 260-pin SO-DIMM modules fit my laptop's memory slots?

The modules use the standard 260-pin DDR4 SO-DIMM form factor, which matches the physical slot found in most DDR4-compatible laptops, notebooks and all-in-one PCs.

How do I install the dual-channel kit, and what step is often missed?

Power off the laptop, open the memory compartment, insert both 4 GB sticks at the same angle until the retention clips click, then verify in BIOS that both modules are detected in dual-channel mode.
