Ok so I'm noob-ish. I worked IT for years but clocks/voltages is a world I've barely explored. I had an undervolt profile with a fixed vcore and some other settings changed around, but I had some stability issues so I set everything back to default. I followed a guide to see if I could get better performance, but he had an MSI board (I have Auorus) so I had to do a bit of guessing on which settings to adjust, since different manufacturers use different phrasing and I'm not pro enough to understand every single abbreviation
(This is the guide https://youtu.be/EToY41V3U04?si=GGKwkq6La3eRAuJT )
I have an Aorus z690i Ultra lite. Here's all I changed:
-Enabled XMP
-Disabled "default performance profile" or whatever it's called. I changed it to "Gaming Profile" and did some benchmarks, then I changed it to "Maximum Performance"
-I changed the Power Limit to 185W, and Power Limit 2 to 250W (assuming the first one was long and the second was short, the interface did not specify what "2" meant)
-I set vCore to offset, set to -0.05mv
-(this may be my mistake) I also set ring voltage to offset, -0.05mv
That's it. Tried restarting, it won't post. Fans ramp up, no display signal. Tried unplugging, pressing CMOS button, holding power button while unplugged, everything. I even removed the CPU entirely and tried booting it like that in the chance I reinstalled the CPU it would reset BIOS settings because of "new hardware." But it didn't, it's like it's completely dead. Admittedly I don't know what ring voltage is, honestly I just dropped it thinking it might've been necessary, and I figured worst case I reset BIOS to default. I've never had a computer die from UNDER volting
Any ideas? If it is dead, any insight? I'm pretty bummed
