EVGA was kind enough to provide an updated BIOS with the memory PPD menu option and VMax Stress menu options exposed. Both enhance performance. Disabling PPD (Power Down) improves memory latency. @tps3443has found his Z590 Dark Cinebench scores have improved and the system is more responsive with VMax Stress disabled.

If you find this beneficial, please email EVGA Support and ask them to make these menu options standard on all BIOS updates. I don't understand why they haven't already done this.

This is not a production release, so the BIOS will show version 0.00 but it works fine.

@tps3443 when you have time please share some results on memory latency with PPD enabled (default) versus disabled and feel free to comment with anything else you find worth mentioning.
