renderfarm ram usage HELP!

ive got 2 days to render my animation… i have 128gb in my workstation and my scene renders fine, reaching about 120 gb ram usage max.

just sent a test scene to the 'farm, where all their machines have 128gb.

got a message back from them saying the scenes went well over 128gb and started heavily paging , and they would be unable to render the shots…

what could be causing this? would a dual xeon use more ram than a threadripper for the same scene for example?

im very worried need to find a solution to this ASAP!!!
