Lenovo ThinkSystem 128GB DDR5 4800MT/s 4Rx4 3DS RDIMM v2
4X77A77034 · Refurbished · 1 year warranty
The Lenovo ThinkSystem 4X77A77034 packs 128GB into a 3DS RDIMM, a stacked-die design whose rank count shows as 4Rx4. The title marks it v2. It runs DDR5 at 4800MT/s with ECC.
Eight V3 platforms are listed: SR630 V3, SR650 V3, SD650-I V3 Neptune DWC, SD650 V3 Neptune DWC, ST650 V3, SR850 V3, SR860 V3 and SR950 V3. The feature code is BNFC.
This is a capacity module. Teams choose it when memory per socket is the constraint, for example large virtual machine hosts or in-memory databases, and when the slot count would otherwise cap total memory.
All three conditions are on offer. New and refurbished units have a 1 year or 3 years warranty, and used units 90 days. Send us the server model and the quantity needed and we will reply with pricing and availability.
