RX 5700 XT Undervolting

[Jon Jon]

Is it worth it to play around with?

 

I am not familiar if Navi benefits in the same ways as Vega does from undervolting.

It does benefit quite a bit if you're running at any stock settings and overheating. Wattman has an auto-undervolt option. Just hit it, click apply, and you're set. You won't notice any performance increase unless you were overheating at stock.

 

If you're not overheating, it's best to just to the auto-overclock instead.

Definitely yes. Easier to check too since MSI Afterburner/GPU-Z can display GPU power usage.

Honestly, Wattman and Navi I find to be very buggy.

 

I actually did a fresh driver install because I switched from using GPU Tweak to Wattman for OC profiles and it made it unstable.

 

As per the Time Spy Stress Tests (Standard and Extreme) my Strix maxed at 80C, and this is with the stock OC profile hitting 1966mhz.

 

I think if I undervolt, I may be able to get it to hit 2150mhz stable. I was toying with that OCed and would get game crashes here and there and it did not pass the stress test.

 

Stress test reported temp rising up to 85C+ after 10-15 minutes or so, before it crashed.

That's good to know!

It's highly unlikely you'll get to 2150 stable. 2130 might be possible though if you up the voltage slightly and increase the power limit to +50%. (that's what I'm running right now)

 

I only get crashes now when I use RivaTuner (comes with MSI Afterburner, and is notorious for causing driver crashes) or if I'm running the Superposition benchmark. (it's stable in everything else)

In what way specifically?

Did you reset the settings back to default before the reinstall? And what changes have you made in Wattman?

I recommend against using Afterburner, as it's basically just doing the exact same thing Wattman is, but isn't quite as capable. Plus the aforementioned RivaTuner causing driver crashes.

I was able to see 2088mhz max boost without really any additional tweaking on GPU Tweak, so that worked out.

 

I find AMD Wattman buggy as my settings were pretty solid until I started playing in there, which then caused me to crash to desktop in some games. I am running the 10/17 release of 19.10.1

 

I may revisit when the next driver update hits, but I think the 1966mhz I am getting just from letting the Strix do its thing naturally is good enough :).
