Its a FTW3 model too OC'd to 2100mhz like a champ

Does a 1070 count as budget if you got it for $300 USD?  I got it before the Etherium mining craze on ebay brand new hahaha. 

DVI can be analog. Hence DVI-A. 

My findings have been entirely opposite. My card can only do 1450MHz if I shove 1.35V down it. What I think is probably happening on your side is that Polaris and any chip made on Samsung/GloFo's 16nm process is very sensitive to temperature. My 1450MHz overclock was stable at 70C, but not at 76C.

It's an MSI Gaming X 8G
 
Do note that it's actually not an amazing piece of silicon. On the stock BIOS it only does 1350. But with an RX 580 BIOS I bet it will do 1400-1420 easily

I still post in this topic a lot because I gave it a follow back when dexter was doing a very bad job undervolting his card. But now it's become a bit of a "post how you OC'd your 480" club.
 
That said when I flash a 580 BIOS on my 480 I will make a separate thread.

@deXxterlab97 So I was playing around with my card again, b/c I upgraded my main rig with some AMD Ryzen 1700 goodness, so my HTPC and RX480 got the Z77 ASRock board with an i7-3770.
I was playing around with voltages, and came to discover this card does NOT respond to raised voltages, rather it loves lower voltages.  Try decreasing voltages from stock by 5-10 mV at a time.  I have mine set to -6mV in Afterburner, and man the thing is much more stable at 1350MHz now.  This card doesn't stop giving and surprising!  What was supposed to be a cheap toss out card ended up being a "performer" in the RX480 world.
 
Not bad, not bad at all.
 
Edit:  By stable I mean it was holding its clockspeed at or near 1350MHz without much fluctuation, and this was done with Firestrike, which doesn't like to stay keep stable clocks, and the other usuals.
 
Edit2: Also I could see the changes by raising the voltage, then running a benchmark seeing the performance drop before my eyes, then as I reduced the voltage the performance results were going up before my eyes.  I  thought I was tripping out until I got off the couch.  LOL

You're complaining because you have to wait a few days for your free product?
Oy. Some fucking people.

There's always someone with a better chip
 
Fortunately for me, I think I got a decent one considering this is a "budget" bargain basement model.
 
So much so that no one has done a PCB analysis, so I mean, I'm happy.  
 
I couldn't take the memory any further in Afterburner, it's maxed out at 2250MHz, and stable in Valley, Firestrike, Timespy, Shadow of Mordor, Grid 2, Dirt 3 benchmarks so far with 1350 core.
 
I don't see the need to push it anymore for daily use, and it seemed to need quite a bit of voltage to even get it to start anything at 1400MHz, so not even gonna try.  I dunno what's considered a lot of voltage on these yet, but +60mV and it still wasn't stable, power limit +5% is the max, so yeah, peak wattage was hitting 170w according to GPUz.

No large improvements in framerates, so whatever.
 
Edit:  Oh, forgot to mention the clockspeed fluctuates, but doesn't seem to fluctuate too much.  Not as stable as being at stock clocks, but still seeing improvements in game and synthetic benchmarks.
