Hi,
I have been using some downclocks for my saphire nitro 5700xt since I think that the temperature and fan speed was a bit on the high side. There has been some fan uptick here and there but I really didnt think about it since it was temporary and it soon went down again. But with playing some half life alyx I noticed that the fan was getting out of control and I had to close the door to my computer room to not get distracted by the noise. I decided to do some testing of my underclocks/undervolts and to compare them and noticed some weird behaviour. In all these stress tests I didnt touch the fan tuning, it is disabled. as is the other settings except AMD SmartAccess Memory
First the default setting, its 2019MHz - 1200mV ( I did for 5 minutes first and it stopped at about these temps/rpm but didnt take a screenshot for comparison)
Default
Here I tried with just power tuning -10% and -20% .Mostly to see how a quick downclock fared and compared to a "real" downclock
Power tuning -10%Power tuning -20%
And here it was with 1800Mhz and 1000mv, the power consumption just spiked when I took the screenshot otherwise it stayed around 150-155 or so
1800-1000
Here is the one I tend to use, 1900MHz with 1050mv, getting a 3k rpm with junction temp below -10% and current temp at the same as -20%
1900-1050
And while writing this post I did a new test.
Going into custom, hitting gpu tuning and advanced control and leaving it at the default 2019-1200 and the fan spins up like the 1950-1050
*And I am on driver version 22.4.1
