Reviewed several threads to understand the situation. BIOS displays 3200mhz timing/voltage as correct, and I enabled XMP in BIOS. However, DRAM speed shows 1599.1mhz on Memory tab while SPD shows 1066mhz. This raises doubts about whether the XMP profile is functioning properly. Additionally, trcd and trp readings seem accurate. The system was purchased for 18-18, not 20-20, and it's an MSI B450M Mortar Max. Also, it runs Corsair Vengeance RGB Pro.
Your memory performance is normal, operating at 3200MHz. The SPD section lists JEDEC standards as the standard rates, which apply to DDR4. The actual speed shown in the memory tab is 1599MHz. DDR stands for Dual Data Rate. Each tick causes a transfer, so 1600MHz equals roughly 3200MT/s. Millions of transfers happen each second. Manufacturers often label it as 3200MHz, but tools like CPU-Z or Task Manager display around 1600MHz accurately. The SPD tab only shows the default speeds and timing parameters, such as 1600MHz and 1.35V.
DDR refers to double data rate technology. (This should be included in the community guidelines: Don't be a dick, be nice to each other, CPUZ shows half of what you paid for, DDR=double data rate)
