AMD 17.12 memory issue

Merry Xmas to all. Santa was good to me and got me a few games but AMD has been the grinch ever since the release of 17.12. This was an issue that I had a few released drivers ago with my HD7950 crossfire setup. There are 2 issues that I am having.

1. The memory clock on my Sapphire Nitro RX580 is always set at 1750MHZ regardless of what I am doing.
2. When i watch You tube videos my RX580 runs at 1350 MHZ on the GPU clock

As a result my RX580 is always 8 to 10 degrees hotter than my RX480.

I would appreciate any suggestions or fixes that the community can provide.

Thanks
