After reviewing the latest BIOS update, I noticed my system's memory performance drops at 3600MHz. Switching to a 3000MHz profile improves stability but slows down some tasks. Anyone have suggestions on how to resolve this issue? The components listed include: Kingston HX436C18FB4AK2 32GB, AMD 5900x, Asus Crosshair VIII Hero WIFI 3080Ti, Samsung M.2 SSD, HDD, and various fans.

Using agesa 1207, your data isn't as reliable now compared to before. That seems unusual. Or could it be a previous version?

Experiencing similar problems recently, even at 3000Mhz. I saw a link to a 16GBx2 kit but mentioned having 64GB of RAM—so it seems you bought two memory kits. I didn’t realize that was significant until I faced numerous issues with my dual 32GB kits. It turned out both Corsair Ven. Pro models had different memory types: one used Samsung and the other Micron (or Hynix). Regardless, even with identical memory chips, some recommend avoiding mixed kits. My RAM performed well at 3133Hz for a while, but after a system crash followed by slowdowns, I gave up and tried each pair of DIMMs in another PC using MemTest86. One set had many errors, the others were flawless. Ultimately, I switched to the (2) x (16GBx2) = 64GB RIPJAWS @ 3200 DDR4 units from a different PC I used for testing. I installed just the two working Corsair DIMMs and everything functioned smoothly, improving stability significantly. They were so defective that they impacted my CrystalDiskMark speeds—from 6.5GB/s to 13GB/s. So, always check the DIE information to confirm compatibility and, if needed, test each unit individually, especially if errors are present, to rule out batch quality issues.
