Lenovo ThinkSystem 256GB DDR5 4800MT/s 8Rx4 3DS RDIMM v2

Two hundred fifty-six gigabytes per module puts the Lenovo ThinkSystem 4X77A77035 in the largest class of DDR5 RDIMMs. It is a 3DS module with an 8Rx4 layout, marked v2 in the title, running at 4800MT/s with ECC. No voltage is listed.

Five servers are named: ThinkSystem SR630 V3, SR650 V3, SR850 V3, SR860 V3 and SR950 V3. Its feature code is BNF8. The list leaves out the water-cooled and tower models that accept smaller modules, which is useful to know when you choose between sizes.

A module this dense matters when you want a multi-terabyte server from a small number of DIMMs. Check the platform's rules on mixing 3DS modules with other types.
