I use wattman.

I do not believe that is possible with WattMan. Definitely should be possible with MSI Afterburner though.

What's the normal voltage to the memory controller and bumping it up will help to get less memory errors or is it only memory related (I know that 8Ghz memory is already a lot to GDDR5).

1000 mv - But no change bumping up the voltage of the memory, you can go to for example 1250 mv - But the memory errors will not be reduced - Usually with the stock voltage you can go to 2150 / 2160 Mhz in the memory without errors.-

The Samsung chips used in top RX models as well as many NV cards should be the same according to pictures from reviews. On NV most of them run 9GHz, 4x2250MHz quite well, above that it gets real tricky and a lot of testing to say whether they are still stable or not, some claim as high as 9.4GHz but I seriously doubt stability of those OCs beyond some games or benches only. Running OpenCL etc. 100% workload for hours on end worked for me to verify the stability of VRAM OC, way more sensitive to unstable OC than any games and benches combined.

2250Mhz without memory errors? So the IMC has a word to say about the memory errors...

I don't think NV cards report memory errors anyway though so they might have some just not enough to reduce performance.

Yes and yes. Pretty much can push as fast as it can go and performance doesn't suffer, it starts to artifact, freeze, crash, reboot sooner than performance goes down.
I know some newer AMD chips report memory errors, the old one I had didn't and it's memory was from factory OCed so badly it artifacted on most GPUs of that model.

Do you notice negative performance with VRAM clock increase over 4x2150MHz? What about errors caused by unstable memory? Might not really be best to hunt for 0 errors if error correction can take care of the few that happen and performance is better.

Hello Radeon RX480/470/460 owners,

We are having our monthly Foldathon from Monday 16th - 18th - 12noon EST.
Would you consider putting all that power to a good cause for those 2 days? If so, come sign up and fold with us - see attached link. 


January 2017 Foldathon


To get started:

1.Get a passkey (allows for speed bonus) - need a valid email address
http://fah-web.stanford.edu/cgi-bin/getpasskey.py


2.Download the folding program:
http://folding.stanford.edu/


Enter your folding name (mine is the same as my OCN name)
Enter your passkey
Enter Team OCN number - 37726


later

so it seems my issue with fan ramping up after zero db state has fixed itself. I haven't done anything except toggle the bios switch back and forth. Now I'm trying to overclock my card and currently I'm testing with these clocks, 1375mhz core, +50% power limit, voltage at +78mv which totals to around 1.15v on the afterburner monitoring. I can run Unigine Heaven stable, no throttling. But once I did a 3dmark Firestrike run that's where the throttling starts to happen. I did notice, the gpu power cause I had it enabled in the afterburner monitoring is reaching around 130w. And once it goes to that mark that's were the throttling happens. Is it because of the card using power beyond powerlimit? Is there any workarounds to this other than bios modding?

Lower voltages, use the Polaris VRM Tool, BIOS mod. Those are your options.
