So here's the issue: clock speeds set in Radeon settings or MSI don't apply and the card goes to its reference card's stock speed (I have an msi r9 280 which has a stock clock of 930 but it goes down to the reference 280's 827). This issue goes away for a boot or two after installing a different driver version or changing between legacy and hybrid boot mode on the card which makes me thinks there's some kind of cache or temp file on the cards firmware/drivers that's reset each time drivers are changed or boot mode is switched. Anyone have any similar problems? Also, no, it is not over-heating, it's at 52 degrees and doing this and yes it's being utilized at anywhere from 85% to 95%. This happens in every game.
