44T1571 is a 4GB DDR3 ECC unbuffered DIMM: dual-rank x8, PC3-10600 CL9, 1333 MHz, low profile. It has feature code 1912 and appears in four Lenovo Press product guides: System x3100 M4, x3250 M4, x3200 M3 and x3250 M3, each with a maximum of four.
In the x3100 M4 guide it is the standard DIMM in models 82x, and in the x3250 M4 guide in models 72x. Those two servers take only DDR3 ECC UDIMMs in four slots, installed in identical pairs.
On the x3200 M3 and x3250 M3, up to four dual-rank UDIMMs are supported for 16GB, and UDIMMs cannot be mixed with RDIMMs. With a Xeon 3400 processor the memory runs at 1333 MHz with one or two DIMMs per channel; with Celeron G, Pentium G or Core i3 processors it runs at 1066 MHz.
Its 2GB single-rank sibling is 44T1570 (feature code 1913). The 8GB 90Y3165 and 1600 MHz modules such as 00D4955 are listed for the M4 servers. If 8GB per slot is needed, pick 90Y3165; for 1600 MHz at 4GB, see 00D4955, and the IBM System x memory hub carries the rest.
Fit check: confirm the server is one of the four listed and that no RDIMMs are already installed.
