About this kit
- EXACT-MATCH UPGRADE — 32GB (2X16GB) kit DDR4-2666 (PC4-21300), 2Rx8 ECC, 1.2V, CL19, 260-pin SODIMM. The precise rank, voltage, and speed your system's memory controller expects, so it's recognized at full capacity and posts correctly.
- VERIFIED FITMENT — Direct replacement for D4ES03-16G-22SERIES-V26. The 260-pin ECC SODIMM form factor required by ECC-capable NAS Devices and compact servers — not a desktop UDIMM. Spec-matched to your unit's memory-population rules.
- DATA INTEGRITY — On-module ECC catches and corrects single-bit errors on the fly — protecting against silent data corruption and unexpected reboots in the 24/7 RAID and storage workloads ECC NAS and compact-server systems run.
- CHECK YOUR CONFIG — NAS and system memory support varies by model. Check your unit's compatibility list and manual for supported capacities and approved DIMM population before purchase.
- LIFETIME SUPPORT — Backed by a lifetime replacement warranty and free US-based technical support.
