DDR5 7200 mhz Stability

I've used 7200mhz but I would get crashes randomly while mid game. Should i lower my mhz to like 6400 or slightly raise my dram voltage to 1.405v instead of 1.400v?

Here is my mobo manual

• 1DPC 1R Max speed up to 7200+ MHz
• 1DPC 2R Max speed up to 6600+ MHz
• 2DPC 1R Max speed up to 6400+ MHz
• 2DPC 2R Max speed up to 5600+ MHz
