I have one with filled 8MB of 70ns dram SIMMs on this 386DX 40 board.
Even standard or tight timings will I need 70ns at all? If not, I'd be very happy to reuse SIMMs in another board with 486dx 33 and populate the 386DX board with 80ns as they are easier to get.

Plug them in and find out 😀 run memtest on a floppy
Problem is I don't have all the parts. 80ns SIMMs are what I don't have, right now. Not bought yet. I still have alternative that I can consider is IBM 3 chips using 3 bit ICs of their IBM design and still sold in bulk.
If I can use 80ns sticks on this 386DX board, then I'll be happy to reuse these 70ns SIMMs on the 486DX board do has whopping 16 slots.
Real reason, 80ns are easier to get. 70ns is harder to find in 9 chip type to match up other 70ns 12 x 1MB SIMMs then finish up finding 4 more sticks at 70ns in future to make a 16MB for 486DX.

Depends. Some late SIMMs (4Mb modules) 80ns probably can work just as fine as 70ns or 60ns. Simply due to improved manufacturing yields.
I must be some kind of standard: the anonymous gangbanger of the 21st century.
