4X32GB DDR4-3200 NON-ECC SODIMM Compatible with Dell Precision 7740 Mobile | PC4-25600 2Rx8 1.2V CL22 260-PIN Unbuffered Non-ECC Workstation Memory, 128GB Kit of 4. Fits Dell Precision 7740 Mobile.

EXACT-MATCH UPGRADE — 128GB kit (4 x 32GB) DDR4-3200 (PC4-25600), 2Rx8 Unbuffered non-ECC, 1.2V, CL22, 260-pin. Matched set from a single production lot — the precise rank, voltage, and timing your system's memory controller expects, recognized at full capacity and rated speed.

VERIFIED FITMENT — Compatible with the Dell Precision 7740 Mobile. The 260-pin SODIMM form factor this workstation requires — not a desktop UDIMM or an ECC/Registered server module. Spec-matched to the workstation's memory-population rules.

PLUG-AND-PLAY PERFORMANCE — JEDEC-standard unbuffered non-ECC module with the SPD profile your system expects: install and boot at rated speed with no BIOS changes. Low-voltage 1.2V DDR4 for cooler, more efficient operation.

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 server memory specialist since 1993, and backed by a lifetime warranty.
