let me guess: 1500-timings to 2000MHz-strap?

Not really no ;-)
Completely changed the memory block.
I'll show a screenshot later :-)
Well Eliovp, you've got the best result of RX 480 so far which I've seen. It'd be great if you could tell us about the version of that RX 480, your OS, the driver you're using and the ROM you're using at the moment. If you could share your other hardware configuration, then it'd be even better.

Sure.
Here's a screenshot of the rom opened in PolarisEditor so you'll have an idea what i've done with the memory block.
http://oi64.tinypic.com/24onigy.jpgIt's just a Reference Sapphire 480, Samsung 8GB memory (like almost all of them).
OS = Windows 10 Pro
Driver = 16.8.2
Rom = a new one

hollyshit that's very cool
so you use only stock room with polaris editor ? or you use boysie/heliox rom?
anyway can you share your cooling room?
i hope you can share more detail about the step to reach 33mhs
