2-power 2P-KVR21S15S8/8 - 8 GB - 1 x 8 GB - DDR4 - 2133 MHz

Upgrading a laptop that has slowed to a crawl under the weight of modern applications? This 2-POWER 8 GB DDR4 SODIMM module slots straight into compatible notebooks, giving the system enough headroom to juggle browser tabs, office suites, and video calls without constant swapping to disk. It is a straightforward fix for the most common performance bottleneck in portable computers.

Key specifications

• Capacity: 8 GB (1 x 8 GB module)
• Memory type: DDR4 SDRAM
• Speed: 2133 MHz (PC4-17000)
• Form factor: 260-pin SO-DIMM
• CAS latency: CL15
• Voltage: 1.2 V
• Error correction: Non-ECC
• Buffering: Unbuffered
• Module rank: Single rank (1Rx8)
• Data transfer rate: 17 GB/s

Why choose it

Built to JEDEC standards, this module delivers stable performance at the rated speed without the need for manual configuration. The low 1.2 V operating voltage helps keep power consumption and heat generation in check, which is especially valuable in thin laptops where battery life matters. Installation takes minutes, and the single-rank design ensures broad compatibility with a wide range of notebook chipsets.

Ideal use cases

• Breathing new life into an older laptop used for everyday productivity.
• Adding memory to a compact PC or mini-ITX system that requires SO-DIMM modules.
• Upgrading a work-from-home notebook for smoother multitasking and video conferencing.
• Replacing a failed module in a laptop that refuses to boot or crashes frequently.

Good to know

Before ordering, confirm that your device accepts DDR4 SO-DIMM modules and supports 8 GB per slot. The module is unbuffered and non-ECC, which is standard for consumer and business laptops. It operates at 1.2 V and is backward compatible with DDR4 systems that run at lower speeds if the chipset requires it.
