I have an RX 480 Nitro+, at stock, factory overclock (1342MHz/2000Mhz).

I've noticed that the core clock in 3DMark (none of the tests seem to matter, be it Firestrike, TimeSpy etc) is throttling and never peaking to 1342, it'll instead hover around 1280-1300, with the GPU load at 100%.

This only seems to be happening in 3DMark, where as I can run Heaven and Valley for hours on end and it won't budge, it'll stay locked on 1342.

I'm also using an aggressive fan curve to keep it under 70c, so GPU temperature isn't going any higher than that, so it can't be thermal throttling, right?
 
Whats your CPU? Because especially Spy is CPU bound.

Have you given to the card bit extra power, if not raise the Power Limit on MSI AB to maximum (not the vcore power)
And let us know your results.

Similar behaviour my Nano has. At stock speeds, goes to sleep on 3D mark hovering at 800-850. When overclock it to 1140/1150 it works at full speed on those benchmarks.

4930K @ 4.4. Will try raising the power limit.
 
Alright, per Panos's suggestion, I maxed out the power limit (did this in Sapphire's Trixx software rather than AB) and it seems to have fixed it. Seems strange to me that I would need to do this.

Since you are half way there, now overclock it also :P

I know seems weird. Same applies to GTX1080, at least the one I had, if you hadn't switched to Maximum performance instead of Power Saving, the setting in the NV control panel.
