All else equal, are larger DIMMs harder to stabilize?

Sorry for the dumb question.  

Assuming same speeds, same latencies, same modern Z790 mobo, is a pair of 24GB DIMMs potential harder to get XMPI stability over a pair of 16GB DIMMs?  Is a pair of 32GB DIMMs harder to get XMPI stability than 24GB or 16GB DIMMs?

Again, only single pairs, same speeds and latencies, same manufacturers.

Hi,
Any increase in density is technically going to put more strain on the CPU memory controller. However, the 24gb Hynix M-Die modules love frequency. There are however some concessions to sub-timings when compared to the 16gb A-Die variant, which are board controlled (or can be manually tuned if needed).

Stick to the 32GB and 48GB kits on the QVL if looking for the most overclocking potential, other IC aren't likely to favour as well.

Thanks ^^

Currently running these:

F5-7200J3445G16GX2-TZ5RK


Thinking about these:

F5-7200J3646F24GX2-TZ5RK

I realize I'd be adding a slight bit of latency (CL34 -> CL36)...

Both are obviously QVL for the Z790-F Gaming 2022

Both good choices. If simply looking to apply XMP personally I would go for the 32GB kit.
