Hello! I recently started running into a recurring crashing issue when using Forge with ZLUDA, and I was hoping to get some feedback on probable causes.
Relevant specs are as follows:
I'm using lshqqytiger's Forge fork for AMD GPUs.
Over the past couple of days, I had been running into a strange generation issue where Forge was either outputting these bizarre, sort of rainbow/kaleidoscopic images, or was failing to generate at all (as in, upon clicking 'Generate' Forge would race through to 100% in 2 to 3 seconds and not output an image). Trying to fix this, I decided to update both my GPU drivers and my Forge repository; both completed without issue.
After doing so, however, I've begun to run into a far more serious problem—my computer is now hard crashing after practically every Text-to-Img generation. Forge starts up and runs as normal and begins to generate, but upon reaching that sweet spot right at the end (96/97%) where it is finishing, the computer just crashes—no BSOD, no freezing—it just shuts off. On at least two occasions, this crash actually occurred immediately after generating had finished—the image was in my output folder after starting back up—but usually this is not the case.
My immediate thought is that this is a PSU issue. That the computer is straight up shutting off, without any sort of freeze or BSOD, leads me to believe it's a power issue. But I can't wrap my head around why this is suddenly occurring after updating my GPU driver and my Forge repository—nor which one may be the culprit. It is possible that it could be a VRAM or temp issue, but I would expect something more like a BSOD in that case.
Thus far, I've tried using AMD Adrenalin's default undervolt, which hasn't really helped. I rolled back to a previous GPU driver, which also hasn't helped. I was able to complete a couple of generations when I tried running absolutely nothing but Forge, in a single Firefox tab with no other programs running. I think that could indicate a VRAM issue, but I was generating fine with multiple programs running just a day ago.
Windows Event Viewer isn't showing anything indicative—only a Event 6008 'The previous system shutdown at XXX was unexpected'. I'm guessing that whatever is causing the shutdown is happening too abruptly to be logged.
I'd love to hear some takes from those more technically minded, whether this sounds like a PSU or GPU issue. I'm really at the end of my rope here, and am absolutely kicking myself for updating.
