Your performance drop for a B450-I ROG STRIX depends on your specific setup and how the RAM is connected. The upgrade from 16GB 3200MHz to 64GB 3800MHz can significantly boost speeds, especially with dual-rank memory. Check your motherboard’s specifications to confirm if your RAM is single or dual rank before the upgrade.
MiniITX is typically ideal for DRAM OC since it offers just two slots near the CPU socket.
mITX has the best memory topology just due to the short distances between the slot and the CPU. Also because no one expects having more than 2 sticks at a time, it doesnt have to worry about sticks on the same channel with different trace length. Ground layers that can help with interference shielding is also cheaper to add on a board that's smaller. So yeah, if there's anything memory related to receive "a penalty", it's the bigger boards. mITX boards can suffer when it comes to power delivery to the CPU, but this doesnt seem to be what you're asking about.
