Feeling stuck—any advice would be welcome!
DDR technology allows RAM to perform two tasks per clock cycle. When CPU-Z displays a physical clock speed of 1600 MHz, the actual memory performance should be around 3200 MT/s, though it might be misrepresented as 3200 MHz. For accurate readings, aim for about 1800 MHz (with minor variations).
NZXT Cam likely displays clock speed, though uncertain. Consider using CPU-Z for confirmation: https://www.cpuid.com/softwares/cpu-z.html. Check if it also shows 1600 MHz. As mentioned, that would imply a performance of 3200 MT/s. Having four memory sticks increases load on the memory controller; running at 3200 MT/s instead of 3600 MT/s may be the best you can achieve. You might want to test with two sticks first and see if it reaches 3600 MT/s (around 1800 MHz).
It indicates you're operating at 3200 MT/s (1600 MHz multiplied by 2). Check the SPD tab to identify the XMP profiles supported; possibly there are two options and you need to choose the appropriate one. It's likely that reaching 3200 MT/s is limited to four RAM sticks, which is the CPU's official maximum memory speed. Experiment with two sticks to determine if it can reach 1800 MHz.
Using two sticks of RAM provides better performance and stability.
Using two sticks requires reapplying the 3600mhz XMP profile in BIOS—it doesn’t happen automatically. They should operate at 1800mhz, but a 3200mhz setup with four sticks works well. The 22ms latency isn’t ideal, so consider reducing it to around 16ms in increments of two.
The screenshots display a genuine CAS version 18. Based on MSI's site, the board handles over 4400 MT/s XMP settings, though the CPU might not support them fully. Likely the XMP is configured at 3200 instead of 3600. It's common for multiple XMP options to exist. In the BIOS, verify if you chose the 3600 setting. The CL18 latency represents the advertised speed for those memory modules. Also, 3200 MT/s works well with AMD series 5000 CPUs. Running RAM at 3600 MT/s won't boost performance by more than a few percent, possibly none at all. Good luck!
It functions adequately with at least two drives. Running 64GB on a B550 with a 5600X at 3600kHz is quite demanding. The CPU’s integrated memory controller will struggle without extensive manual adjustments to timing and voltage settings. With just two sticks and XMP/EXPO/DOCP activated, it should operate smoothly at 3600kHz. The performance at 3200kHz remains uncertain.
