Question regrading Ram to get to 64? 2x32 or 4x16 pro or cons?

[Question regrading Ram to get to 64?   2x32  or 4x16  pro or cons?] Just wondering the costs and benefits  if there are any for rendering.

Well, if you have four slots then 2 * 32 would leave 2 free for future upgrades without having to ditch some existing memory.

How many memory slots on your motherboard 4 or 8?

Edit: Google "single dual quad channel memory", if your motherboard supports quad channel, you get more bandwith and less CPU usage

Depending on the platform and ram speed 2 sticks may be more stable.

Fewer bigger sticks are always better. Also some MB's cannot run 4 slots at higher speeds.

If this is DDR4 then the 16GB sticks are the ones that come in higher speed variants. (No technical reason for that, there just wasn't the market to make high speed 32GB DIMMs)

There may have been some particularly cheap motherboards that could not cope with 4 sticks. (At this stage when DDR4 is as mature as it's going to get, that should not be a problem!)

If you're aiming for 4x32 in the short term, but only 2x32GB for now then that's OK...

Otherwise 4 sticks of 16GB DDR4 will be substantially quicker than 2x32.

(On my own DDR4 PC, I went from 2x8GB@3200 to 4x16GB@3600.)

Accessing more than 8GB on DDR4 DIMM is done via something called 'Page Rank'. Page Rank is one of the biggest changes with DDR5, you'll need different advice!
