2X16GB DDR4-3200 ECC SODIMM Compatible with Synology DiskStation DS1525neo+ | PC4-25600 2Rx8 1.2V CL22 260-PIN Unbuffered ECC NAS Memory, 32GB Kit of 2. Fits Synology DiskStation DS1525neo+.

EXACT-MATCH UPGRADE — 32GB kit (2 x 16GB) DDR4-3200 (PC4-25600), 2Rx8 Unbuffered ECC, 1.2V, CL22, 260-pin. Matched set from a single production lot, the precise rank, voltage, and timing your NAS's memory controller expects, so it is recognized at full capacity.
VERIFIED FITMENT — Compatible with the Synology DiskStation DS1525neo+. Matches the ECC SODIMM part numbers Synology lists for this model (D4ES03-8G, D4ES03-16G, D4ES04-4G). The 260-pin SODIMM form factor this NAS requires, not a desktop UDIMM or a registered server module. Spec-matched to the NAS's memory-population rules.
REPLACE THE FACTORY MODULE — This model ships with one 4GB non-ECC module. Modules in a multi-module setup must be identical, and ECC and non-ECC modules cannot be mixed, so remove the factory module when fitting NEMIX ECC modules. The processor runs memory at up to DDR4-2400; faster modules clock down automatically.
CHECK YOUR CONFIG — System memory support varies by model and processor. Consult your system manual for supported capacities, approved DIMM population order, and installation steps before purchase.
LIFETIME SUPPORT — Backed by a lifetime replacement warranty and free US-based technical support. Researched, matched, and compatibility-tested by NEMIX RAM, a US-based memory specialist since 1993, and backed by a lifetime warranty.
