Hi all, just registered as am a first time purchaser of an RX 6900 XT.have been with Nvidia for 20 years but couldnt resist the new Radeon bang for buck.My new card kept resetting.several times in one game.Have solved the problem so thought would pass it on just in case anybody else is having a similar issue.my card wasnt getting the power it needed so i changed the settings on my corsair 1200 ax to single rail (was on multi-rail).the card has not crashed once since!.Hope this helps some other users.
