Try setting compatibility in wattman, it reduces how much power the card takes from the pci-e port. Try power Efficiency setting too, in wattman.
Check the windows power profile?? Set it to 100% and see what happens.
I have the power settings set to high performance - is that what you mean?
Yeah - try compatability in Wattman and see if it helps. It could be the VS 550W is not pushing enough power to the motherboard. They are rather average PSUs from what I gather.
Like I said also do the malware check,since someone had GPU issues with their R9 290 not working properly and it was a Trojan using their GPU to mine Bitcoins causing gaming performance to tank.
Edit!!
Compatability setting draws more power through the PCI-E power connector.
Its really weird - mate has a RX480 Nitro+ OC running on a B150 motherboard fine. Never had any issue and he is also running a Core i7 which draws more power than your Core i3.
I assume you are running the latest drivers too??
All drivers installed? Checked for any yellow flags in device manager?
which version of windows are you running??
and you sure you've updated the latest bios? something is funky
Try some benchmarks and compare with similar specs to see if there is a problem.
I'm a bit suspicious of a throttled CPU at 800, that can't be right.

Andi.
PS Also that CPU is pretty low end, dual core only. Have you enabled Hyperthreading in the BIOS. I'd be looking at an i5/i7 for gaming.
I think you should have held onto the RX470 for a bit longer - methinks the PSU is the issue.
Try Cinebench with and without the GPU in it.
The end of this thread hints at something called "away mode" being enabled in the bios, under performance and power saving tabs. Not too sure if it's going to be an option in your bios but it's worth a shot i guess!
P.s. i had started reading this thread hoping there would be a happy ending, but, finding that there wasn't caused me to have a little sleuth to see if anyone else had experienced similar throttling, it doesn't really seem so for your cpu/gpu combos but, they may be related...
I ordered the wrong card when i got the 470, I wanted the 480, I was torn between that and the 1060, so if I can get it working I'm happy with that move - amazon have already refunded my money!
Will cinebench tell us anything that the 3dmark results haven't?
