QNAP RAM-8GDR4T0-SO-2666 is an 8GB DDR4-2666MHz SODIMM module designed for QNAP NAS systems and compatible laptops requiring low-power memory expansion. The PC4-21300 specification delivers 21.3GB/s bandwidth over a 260-pin SO-DIMM form factor, supporting 1.2V operation typical of mobile and compact embedded platforms. Non-ECC, unbuffered design suits general-purpose NAS acceleration and client-side workloads where error correction is not required. Common applications include expanding QNAP TS-series NAS cache, upgrading NAS-attached compute nodes, or replacing failed SO-DIMM modules in compatible business laptops and thin clients. Verify motherboard compatibility before purchase, as DDR4-2666 support varies by platform generation. Tested and guaranteed; available via quote.
