I've done it with an adapter and by cutting the trace. Both work fine and my Williams boards and PSs love the newer RAM.Anyone recommend the ram upgrade on Robotron with adapter?

Robotron ram upgrade?? What is it, what I miss??
4164 ram. it has its advantages over the original 4116 ram, notably being that it runs off +5 only (instead of the tri-voltage +5, +12, -5 arrangement). it will run much cooler as a result.
there's a lot of other more important areas to focus on with these games though, mainly regarding power. you'll want to replace the MPU/rom board caps (100 uf/25V), the power headers, and for added measure the power plugs with new Molex parts. your boards will lose a lot of voltage if these 3 elements are left alone, which will make your boards typically not work right.
4164 ram will be the last thing you want to do. the 4116 ram isn't necessarily bad, the only drawback is if you're running an old linear power supply that hasn't been rebuilt properly you run the risk of losing a voltage and thus the entire game will be a wash. many people are proponents of just dropping a switcher and 4164 ram, these alone will not fix your game. I already said why.
Agreed, but for games with solid power and boards, the 4164 (or bigger) is a good solution. I run an original linear PS and just pulled the- 5v fuse.4164 ram. it has its advantages over the original 4116 ram, notably being that it runs off +5 only (instead of the tri-voltage +5, +12, -5 arrangement). it will run much cooler as a result.

if you're psycho and are running a linear that HASN'T been rebuilt, then stick to 4116 ram. if the +5 sags, there's a chance the 4164 won't work I've found.
I encourage the "OCD method" that I outline frequently with these games. you'll never have problems again unless a ribbon cable goes bad.
