00YG941 is a 128GB TruDDR4 3DS RDIMM from Lenovo, organised 8Rx4 at 1.2V and rated PC4-2400-R (2400 MHz). Lenovo Press lists it with feature code B0MV in the System x3850 X6 guide, up to 96 per server, and the System x3950 X6 guide, up to 192 per server, in both cases 24 per processor.
Lenovo groups it with the 2400 MHz TruDDR4 RDIMMs and LRDIMMs for E7 v4 processors, also supported with E7 v3. The x3850 X6 runs TruDDR4 memory at up to 1866 MHz, even though these DIMMs are rated higher.
Each processor in the x3850 X6 has four memory channels built on SMI2 chips, with three DIMMs per channel, and the DIMM slots sit on the Compute Book with the processor. With 96 of these modules, the x3850 X6 holds 12TB.
It is the largest DIMM in the table, above 46W0841 (64GB LRDIMM), 46W0833 (32GB), 46W0829 (16GB) and 46W0821 (8GB). Smaller TruDDR4 2400 RDIMMs from the same table are 46W0829 and 46W0821; the IBM System x memory hub has the full list.
Fit check: confirm an x3850 X6 or x3950 X6 with E7 v3 or v4 processors, and expect the memory to run at no more than 1866 MHz.
