Thanks for this info Tony.

I tend to not use sockets in this case.
I will test the boards after freeing the holes, test the 41256's before use, but then I will just solder them.

I am just fighting multiple 4116 failues in my Lilith's spare memory boards, and these drams are soldered in.  It is a pain, but i believe 41256 are less errorprone then those  3-voltage 4116's and I just dont like sockets.

BTW Lilith hardware and microcode docs are up on bitsavers, if you are looking for some bedtime literature !
