I have a Powercolor Red Devil 6900 XT that works fine(browsing/desktop use) until I load up a game and few seconds later it reboots the entire system. Suspected to have a VRAM issue but I can’t underclock/undervolt the memory on AMD Adrenline or MSI Afterburner as the sliders don’t allow me to go lower than 2000mhz which is the base clock of the VRAM. I would like to know if there is another tool that allows me to downclock the VRAM past 2000mhz?

FYI I have a Corsair RM750x and it ran another identical 6900xt at full load with no problems.
