I've been trying to run Diablo 2 on my PC, but have been having consistent crashes every single time I launch the game. Within 10 seconds of opening the application, the game crashes to desktop. Sometimes the monitors flicker and I get an AMD error message, but this doesn't happen every time. After troubleshooting with Dell, AMD, and Blizzard, and getting nowhere, I did some research and found some random threads online where they suggested adjusting some settings in AMD's software to fine your GPU and iron out some performance issues.

I changed one setting and was able to get the game to run with minimal issues, but was advised by AMD NOT to use this as a work around and to ONLY use factory settings (which apparenly are not capable of running the game). They gave me the spiel about overclocking ruining your card and voiding any possible warranties. Right now I just want to find out if what I changed is even overclocking, and what some of the fine tuning settings actually do to the GPU when they are adjusted.

The settings I adjusted are in the image above. These are the factory settings. I changed the value under Frequncy "P3" to 1500, and was able to run the game. What does this actually do to my GPU? Is this overclocking? Underclocking? Is there something wrong with my card if it can't run games using the factory settings?

P3 has two parts, the upper (frequency) and the lower (voltage).

I don't know specifics, but I would expect those to be the three performance settings (ie: low, med, high).

If you change the frequency of P3, you actually slowed the card. If you change the voltage, then you increased the voltage being used.

Are you using the new release of Diablo II or the original? I'd suspect some underlying OS issue, driver is at fault if you are trying to run the original release. The game is 20+ years old, and older games don't always work, work well on a new OS and/or hardware.
Thanks for the help.

I'm playing Diablo 2: Resurrected, so compatibility between old game and new drivers shouldn't be an issue. I had issues with the Beta and couldn't run it, but was able to play it for several weeks when the full game was released. This made me think there was an issue with the Beta itself and not the GPU or drivers. After a few weeks, it started crashing and now crashes every single time the game is opened.

I lowered the frequency, and believe the voltage also went down as well. It looks like they are tied together so when one is lowered, the other goes down incrementally as well. Isn't this technically undervolting?

AMD obviously warns against overclocking and I can understand how this damages cards, but what about undervolting? Is undervolting bad for a GPU? Also, why would undervolting fix this issue?
Assuming my assumption is correct, you simply lowered how fast the card can actually run. I also wouldn't expect that to even make a difference in the problem that you are experiencing. Most likely, whatever was going on with the Beta, is still an issue on your machine.

Win10 fully patched? Latest AMD gpu drivers installed? Attempted using an older gpu driver? Contacted Blizzard support (at least I think that is a Blizzard game)?
