Viking Technology DDR4 Memory Modules — LRDIMM & RDIMM to 256GB, VLP / ULP / Mini / SORDIMM

Specifications

Overview

DDR4 remains the installed base in a large part of the industrial, telecom and defense market, and those platforms have the same mechanical constraints they always had: no room for a full-height module, and a qualification cycle too expensive to repeat for a new memory vendor. Viking Technology's DDR4 line answers both by covering the full footprint ladder within one generation.

Capacity at the top of the range is served by 256GB LRDIMM and 256GB RDIMM modules, with 128GB UDIMMs for unbuffered designs. The low-profile tiers follow the same pattern as the DDR5 line — VLP RDIMM and VLP UDIMM up to 32GB, ULP RDIMM up to 16GB, MiniRDIMM and MiniUDIMM up to 16GB, and the smallest VLP/ULP MiniDIMM families at up to 16GB. The small-outline SORDIMM and SOUDIMM families reach 32GB, with VLP SORDIMM at up to 16GB.

Because the SORDIMM and SOUDIMM families exist in DDR3 and DDR2 as well, a platform being carried forward from an older generation can often keep the same mechanical envelope and board outline and change only the memory generation. That continuity is the main reason embedded OEMs standardise on a vendor with this breadth rather than sourcing each footprint separately.

QS Compute supplies Viking Technology DDR4 modules to order, including long-lifecycle and last-time-buy programmes for platforms with extended production lives.

Key Benefits

Widest DDR4 footprint range — from 256GB LRDIMM/RDIMM down to 16GB ULP MiniDIMM. 256GB per module for capacity-dense memory subsystems. Cross-generation continuity with matching DDR3/DDR2 footprints. Long-lifecycle availability for industrial platforms with multi-year production runs.

Applications

Industrial and embedded PCs with height-limited slots · telecom line cards and AdvancedTCA/MicroTCA blades · defense and aerospace memory upgrades · legacy server memory expansion and last-time buys · edge platforms in sealed or conduction-cooled enclosures
