I can adjust the CL-tRCG-tRP. However, the MB BIOS will not allow me to adjust the tRAS. It is set to default (AUTO). I have made adjustments to the other timings and met each attempt with failure. The sys becomes unstable or simply won't boot into Windows. The MD manual shows all the timings to be adjustable.
Additionally, I loose my display and have to remove the GPU, reboot, reinstall the driver's, reboot and reinstall the GPU to return to hSLI mode.
The CPU and RAM are designed to work together. The MB supports both per conversation with MSI and QVL. MSI say's the options for timing adjustments should be available to me in the BIOS.
Any thoughts or advise would be greatly appreciated.
