46W0843 is a 64GB TruDDR4 memory module, 4Rx4, 1.2V, running at 2400MHz in the low-profile LRDIMM (load-reduced) form.
It is a replacement memory module for the Lenovo System x3650 M5, machine type 8871.
The System x3650 M5 takes 64GB TruDDR4 4Rx4 2400MHz LP LRDIMMs (option 46W0841) up to 12 with one processor and 24 with two. With two processors, 24 of these 64GB LRDIMMs reach 1.5TB of memory. LRDIMMs and RDIMMs cannot be mixed in the same server.
Every DIMM runs at the lowest of the processor memory speed and the speed set by the number of DIMMs per channel. Memory protection on the x3650 M5 covers ECC, Chipkill for x4-based DIMMs, memory mirroring and rank sparing. Related modules are in Lenovo server memory.
