Overclocking
The Gigabyte B550M AORUS Pro showed decent headroom for overclocking. I was able to achieve 4.44 GHz at 1.35 V core voltage.
For the B550 launch, I am also conducting a memory timing test. This is a pass/fail test where I load the DRAM Calculator "fast" preset for my Trident Z Neo kit (Samsung B-die). A board receives a pass if it can run through three loops of MemTest64 with no errors. Partial credit will be given to a board that can get into Windows, but fails MemTest. This CPU and memory combo with exactly these sticks can run without errors at these settings, as validated by my MSI X570 ACE motherboard.
For high frequency overclocking, the Gigabyte B550M AORUS Pro did well, reaching 4000 MHz stable at XMP timings and voltages on my Trident Z Neo kit.
The Gigabyte B550M AORUS Pro booted into Windows with the tight B-timings, but failed memory stability testing.
