2x24gb vs 2x32gb DDR5 (Single vs Dual Rank ?)

[Buckster]

2x24gb 6000 CL30 kits seem to be about same price as 2x32gb but am I right in thinking 24gb modules more likely to be Single Rank and the 32gb ones Dual Rank. I've been looking at Corsair kits

Is there a negative if they are dual rank (running at EXPO settings) - or is it actually an advantage ?

2x24gb is probably plenty enough memory, but if 2x32gb is similar price may as well go for that - just was confused with the dual vs single rank

single rank modules (24gb ones) - more likely to overclock ?

most likely will be paired with a 9700k CPU.

I did consider 6400 CL32 for same price but I seem to have raid 6000 CL30 is probably optimum.

Any advice much appreciated thankyou

thanks very much for all of your replies much appreciated

it seems if running at stock then it's a no brainer - 2x32gb

but if I was to overclock the memory a bit I might be better off with the 2x24gb ? which if Corsair CL30 could be Single Sided M-Die ?

and yes sorry meant the 9700x. It seems to react better to higher clocked memory hence the wonder if I were to take a chance on 2x24gb to see if I can clock it (and the CPU memory interface) to beyond 6000

9700x seems to in tests scale better with memory >6000 than say 7800x3d which doesn't need it

the only game I'm to play that may require >32gb is FS2024 - it seems 32gb is right on the edge, hence why some tests seem to show much smoother experience with 64gb. I'm thinking though 48gb would be plenty

thanks very much I'll take a look at the link

it's odd that there seems to be quite a difference in a good few benchmark videos of FS2020/FS2024 - as in the videos you can see whether 32gb or 64gb the game is only using 32gb - BUT when you do say an external rotate/pan round the plane looking at the scenery the 32gb seems to stutter quite a lot, yet 64gb smooth. both showing same amount of memory used though.

maybe although only 32gb is being used the 64gb allows for "space" for the new stuff to be appended into the memory in parallel to un-used being removed from memory, and 32gb doesn't lend to that luxury ? not sure its a bit odd
