Product detail / 4X77A99755

Memory specification and compatibility.

64GB TruDDR5 5600MHz RDIMM for Lenovo ThinkSystem V3 servers — SR630 V3, SR650 V3, SR860 V3, ST650 V3. A single 64GB DIMM doubles the per-slot density of the 32GB variant (4X77A99752) already in the catalogue, enabling larger memory configurations in slot-constrained deployments. 2Rx4 organisation delivers strong bandwidth for compute-intensive and in-memory workloads. Customers buying SR630 V3 or SR650 V3 servers frequently want to populate all slots with 64GB for 512GB+ total memory. Without this SKU, the Lenovo DDR5 range tops out at 32GB per slot, forcing customers to seek memory from alternative suppliers.
