The 128GB DIMM That Takes a 2-Socket Server From 4 туберкулез к 8 TB Without Changing Anything Else
A dual-socket Dell R760 has 32 DIMM slots. Populate all 32 with 64GB DIMMs and you get 2 ТБ. Populate them with 128GB 3DS RDIMMs and you get 4 ТБ. With 256GB 3DS DIMMs, 8 ТБ. The Samsung 128GB DDR5-5600 3DS RDIMM is the middle step — the density that turns a memory-hungry virtualization host or an in-memory database server from «can’t fit the workload» к «has headroom for growth.» It is a 3D-stacked (TSV, through-silicon via) registered DIMM with 4 ranks, ЕСС, and on-die thermal sensors — the densest standard form factor before stepping up to the 256GB tier.

3DS Stacking Explained — Why 128GB Costs More Than Two 64GB DIMMs But Is Worth It
A standard 64GB RDIMM has DRAM chips on two sides of the module (dual-rank). A 128GB 3DS RDIMM stacks DRAM dies vertically using through-silicon vias — 8 dies stacked per module with vertical interconnects. This achieves higher capacity in the same form factor, but the TSV process is more expensive to manufacture, which is why 128GB 3DS costs more than 2x 64GB RDIMMs. The value proposition: a 2-socket server has a fixed 32 DIMM slots. Populating 2x 64GB per slot is impossible — the slot holds one DIMM. 3DS stacking is the only path to 2 TB+ per node on a dual-socket platform.
Совместимые платформы
DDR5-5600 4Rx4 3DS RDIMM. Compatible with Dell PowerEdge 16th Gen (660 рэндов, 760 рэндов, 770 рэндов, 860 рэндов, 960 рэндов) and xFusion FusionServer V7. Verify platform QVL for the specific part number. At 1DPC (1 DIMM per channel), the 128GB 3DS RDIMM runs at DDR5-5600. At 2DPC, speed drops to 4400 МТ/с (platform-dependent). Do not mix 128GB 3DS RDIMMs with 64GB RDIMMs on the same channel — rank count mismatch forces both to train down.
