Why is Enshrouded dropping frames during big builds with Crucial 16GB DDR4? Voltage lag?

Seriously, this is a joke. I have 3200MHz RAM, but in Enshrouded, it felt like I was running on 2133MHz. Comparing default and overclocked settings, I noticed the memory controller was having massive latency spikes when handling complex building instructions. I tried enabling 'Ultimate Performance' mode in Windows, but all that did was make my fans louder without adding a single frame—a total waste of time. I then went into the GamePP BIOS Load-Line Voltage Adjust Wizard, nudging the SoC voltage from 1.1V to 1.15V and tightening the tRFC. AIDA64 showed a bandwidth bump of about 12%. I used the GamePP System Backup & Config Export Tool to backup.
