Specs:
Gigabyte B660M Aorus Pro AX DDR4
Intel Core i5-12600K
No GPU card, I’m just using the iGPU
EVGA 700w (swapped it in but it was a Corsair)
Built PC in March 2022, been sitting off most of that time.
I started having stability issues even though I’ve barely used my new build. First weird issue was power supply wouldn’t turn on, clicking away or shutting down randomly. Bought another one without the green energy stuff and it powers on fine.
However… when I try to do any cpu stress test (cpu z, or Linux stress command) there’s a level where it just shuts off.
Which is odd because I stressed it out weeks/months ago and it was fine. Anyways..
In Linux (just cuz I made a boot drive so I don’t risk corrupting my windows 11 install) I would slowly add cpu cores (to stress) by typing “stress -c number” number being the # of cpu cores to use. Get up to 5 and then a few minutes later will shut down. Hitting “stress” in cpu z instantly shuts it down.
So now I changed some power settings in bios to use a maximum of 50 watts and now it’s stable. If I boot into windows and use the motherboard apps I can mess with it, starts being unstable again if I set it to 57w and hit the bench/stress buttons in cpu-z. Turned it back down to 42w to be safe. The speed slows down the lower it’s set which sucks.
What’s odd though is the cpu temps never really go high, even before when fully stressing it out. So I don’t think it’s a heat issue with the cpu… never goes above 45ish degrees.
There is this metal thing on the motherboard that says “Team Up, Fight On” which sorta looks like a heatsink which rattles a little… is this normal? It’s got one screw, it won’t tighten anymore than it already is. It just slightly moves with touch, like it’s not down all the way. Wondering if this is a problem. It came like that but seemed fine for months.
With the Turbo Power Limits in bios (1 and 2) set to 50w in bios it seems stable finally.. but I still don’t know what the issue is. Tried swapping out ram sticks etc. Seems related to spikes of high power usage when stressing it.
I’m tempted to flash the bios to a newer version but it still doesn’t explain why it did work fine for months.
Im starting to think it’s the motherboard.. going glitchy. Any ideas on what to try next? I don’t have much hooked up to it like HDs etc. tried one stick of ram (instead of two 8gb) I did not try all available slots though. I guess I’ll try putting just 8gb in on a slot that isn’t used and see if it’ll go over 57w/work without a limit.
—- Seems like it might be worth a shot to update the bios… or take the cpu heatsink off and check it but seems like it’s running super cool. Seems unlikely it would heat up instantly to where it would then shut down. But I’ll try that next.
The power limit settings are nice to make it stable, is there any other weird settings I could try?
—- edit: just now noticed that the cpu core voltage is dipping well below 0.5v… even down to 0.2v. It’s bouncing up and down.. and I am seeing alerts in the Aorus app saying warning cpu vcore below 0.5V. Ugh 😩 so maybe the board regulators aren’t working or can a cpu go bad?
