5700xt undervolt/underclock

[Wraithsiege]

I used to run my card at 1905mhz 1v but after reinstalling windows every time i play something i will get black screen for 10 second in game and then the game will crash. The system stays unresponsive for a minute(only mouse can be moved) and then it would unfrezee followed with the message Default Radeon WattMan settings has been restored due to unexpected system failure. I tried playing games with stock settings 2036mhz/1200v and no problems except the card works 20c hotter and is loud. So 5700xt users who undervolt/underclocked your card, which settings do you use?

[_I_]

psu brand/model

it will throttle when hot, check its fans to make sure they spin freely and heatsinks are not dusty

poor or overrated psu can cause crash/driver errors

Which drivers are you using? Many of the drivers for these cards have had black screen or crashing issues.

what about watercooling? then your card is silent...

^ what firegryph said

the xt drivers are horrible, check on the amd driver forums also

I checked with AMD and for the last 2 months it has a problem where the card randomly losses signal while gaming or on desktop and it said that disabling hardware acceleration on other apps help which i did(when i had hardware acceleration it crashed whole system tho). IDK if it is important but crashes dont happen mid round in games. In r6 siege for example it happens during pick and ban phase, in csgo during the buy phase, and in gta v in lobby while waiting for the host to start the job or while picking clothing for the heist. Im having NZXT E650

You will have to start from scratch with undervolt, most likely.
They change stuff from driver to driver (probably trying to make it work), so settings that work on one version will not necesserily work on another one.
Also if it crashes in browser and such with hw acceleration on and stock settings - just RMA the thing, that's what i did with mine. Buying videocard only to not use it (and force cpu do its job) seems kind of silly.

I see, i never tired experimenting with thr voltages myself. How should i do it. Should i use heavenvalley and lower the voltage for 20mV every time to see if it will crash. Also how long should i run it to know if its stable?

Well, you have some settings now but stuff is crashing. Try increasing voltage in something like 10mV (or 20, 30, etc mV depending on how lazy you are :) ) steps and just use computer normally. If it crashes add one more step etc. As long as you are not going above stock 1.2V it is perfectly safe.
You can run some benchmark for quick verification, like superposition, 3d mark, or built-in benchmark from any game, but it will never give you a guarantee that the card is stable with this settings in all conditions.
Using purely synthetic benchmarks/stress tests like furmark is even less useful, because they generate very specific load, and being stable in this specific load does not equal being stable in games, browser or whatever other real usage.
