So I'm not sure what is happening, but every time i restart my PC i have to go into AMD Wattman and correct my max clock speed. I have no clue why this is happening but I would really like some help, I've attached a snip of Wattman after a restart.

My rig has a core i7 4790 (non-K) and a GTX 745 in it. and I would love to upgrade very soon. as my motherboard is a cheapo from a Acer prebuild and my PSU keeps craping out on me. And omfg this GPU... you let it run for 10 mins in any graphics intensive game with direct x (AT BASE CLOCK SPEEDS) and it crashes with the message that the device was hung. The thing only has the PCIE slot it is connected to to power the damn things 55w TDP. To put the GPU into perspective if I want to play BF4 I have to play at 900p at min settings and I still have to underclock the GPU if I want to play for more that 10 mins. Gibe nao pls. srsly. This is my only working PC atm and I have the money to upgrade the motherboard and PSU to accommodate a new GPU but i don't have the money to get the GPU, all the nice things i buy would be sitting a case doing nothing.
