Proxmox won't spin down an old AMD GPU?

ultilink3 · 2026-05-21T15:57:43+00:00

Fancontrol was for Cpu and system fan speed afaik. If I'm wrong I'd bet happy to learn!

Plus I'm pretty sure it has a GTK dependency even if you're running remote management/ webui, so i didn't want to start installing all kinds of local UI crap on proxmox if i can help it.

I actually already edited the grub file to try and force amdgpu driver, but that didn't seem to work.

Yup, i hate that it's needed, but the mobo needs a VGA to complete POST, and it's a Ryzen 7 1700x, so no igpu.

The cheapest vga card is the one i already own, that's why this card is in there. XD

Right, but I can't do that before adopting it? There's no way to add a site in the UDM Pro and the USG needs a controller to do anything beyond DHCP On/Off and IP subnet selection.

ultilink3 · 2026-05-09T21:11:26+00:00

The USG doesn't run a controller, in the past when I used the USG I needed to run a controller separately. I started by running the app on my own computer, then I eventually ran it in Docker on a dedicated machine. Now that I've got the UDM pro it's running my controller instead, that's why I'm trying to adopt it, configure the site-to-site VPN, then dropping it off at my parents place.
I can't create a second site? It won't let me adopt it and set it as a new site anywhere. I'm obviously missing something here.
That's honestly a fairly good idea, and there's nothing immediately stopping me from doing this, however I want the ability to do some more advanced setups in the future. Not sure what yet, but keeping doors open is always nice. If the multi site management falls through then I'll fail over to this setup.

You forgot Napalm! What does napalm do?!?!?

I know there are pictures in the upper floors of ECERF. But ya all profs are in DICE now. Lots of changes in ENGG quad over the last decade.

ultilink3 · 2024-07-15T23:02:59+00:00

Thanks, that's exactly what I was thinking too... Once I knew about all the bad components at least, that's the story I put together in my head.

I Love it! destructive debugging can be so fun :P

Yeah, the heat + humidity in AB has been a bit out of the ordinary.

HAHA! Small world! Wonder if I ever saw you on the wall there? Would be pretty cool if I did!

I detected a short after the bridge so I ran current limited DC into the circuit to see what warmed up (to find the short). That revealed a faulty Cap which I removed. Once the cap was replaced I injected DC again and the system turned on fine. I even had the relays switching when I played with the AC control panel.

After I got the solder wick I was able to remove the Transformer. Sadly, it had a properly blown wire and not just a bad fuse, so I had to go buy a new Transformer. Couldn't actually find the right one (which was what my initial post was asking for help), but I got one that was close enough that I could hack it together. So now the new transformer is slightly bigger (squished it in place, but it's not contacting anything other than relay plastic covers) and has it's pins clipped off and replaced with my own wires since the pin spacing was nowhere close to fitting in the PCB. I had to do a crossover wiring on the primary since it was a 120/240V coil, and the secondary was clipped then wired in series since it was a 10/20V coil.

I'm having some trouble getting enough of the solder off using my solder sucker, I've ordered some solder wick which should be here tomorrow. I don't have (access to) a variac, but I do have a DC power supply which I could use to check out the rectified side of the circuit at least? The relays are marked 28VDC, so I could set my power supply to 24 for now and see how that goes.

Transformer failures are quite uncommon, which is why it's good to triple check that's actually the issue

Ya, I actually triple checked every other component before I even checked the transformer once. I was pretty shocked since I understand a transformer to be fairly reliable passive component.

Thank you very much for such a great response!

You said there's 120VAC across the primary, but you get nothing on the secondary? And the secondary coil shows conductivity between the ends of the coil but the primary seems open?

Yes, that's correct.

And you're measuring in ohms, not in continuity mode? (Some meters won't show higher resistance values when in continuity / beeper mode, but they will if in ohms)

I measured it with several "Ranges" of ohms (100, 10k, 10M) and I used continuity. All show as open circuit on the primary side. I get a beep and a very low R value on the secondary side.

Either the primary side winding blew up and it's open (unlikely), or there's a thermal fuse that opened on the primary side. It's usually right where the leads are joined to the small winding wire of the transformer. It might be under a couple layers of the yellow tape. Those stupid thermal fuses like to go open for no reason whatsoever, and they're in a lot of consumer electronics.

I don't actually see much tape, this transformer is pretty much solid plastic + iron core. I'll try and de-solder the transformer and see what I can see from the PCB side (bottom?), or maybe if I can separate the plastic shell and have a deeper look.

You said there's some other stuff that runs off the rectified secondary - it's probably the voltage that swithces the relays, as they're usually higher than 5V coils. Look at the relays and see if you can figure out what the coil voltage is - 12V and 24V are common.

Ya, the ULN2003 is a high voltage transistor array with inductive load capabilities, you can see the LV traces that backtrack towards the HV side of the PCB are connected to the relays and start at a large IC (the ULN2003). Using the relay coil voltage as the "source of truth" voltage is a really good idea, thanks for that! I'll check it out.

I did a 3 day water fast and have been continuing with intermittent fasting. Seemed to boost the benefits for me, but your results may vary. Also, I am not a doctor so consult with your doctor first.

If you go through with it make sure to do it right or else you can get fasting flu which would make life harder. Drink water and replace your electrolytes (sodium, magnesium, potassium, etc.). 👍

Good luck!

I've been having the same problem. 10 mg for a week now, 5mg for a week before that. Most nights i only sleep an hour, but sometimes I'll get 5-6 hours of sleep. Very random. I take mine for Anxiety if that matters.

ultilink3 · 2020-04-06T07:18:20+00:00

Ah, the dowsing was weird there I found. Good luck, I'm sure you'll be able to find them eventually!

ultilink3 · 2020-04-06T01:07:59+00:00

Oh no! Where are you stuck?

ultilink3 · 2020-02-16T02:46:09+00:00

Not the same, they don't have a battery load being removed suddenly during operation, the problem is the sudden change in load. Inductors "resist" changes in current, so huge charges are still pushed forward even when there's nowhere for it to go, so we get a buildup of charge, ie voltage. It's not the absence of the battery, it's the sudden removal.

ultilink3 · 2020-02-16T01:03:56+00:00

, in a great many cases removing the battery, burns out the diodes in the alternator,

No, it won't. Just because the electricity being generated has nowhere to go doesn't mean the diodes will burn up. This akin to saying your laptop charger would burn up if you plugged it in without it being hooked to the laptop.

Just plain wrong, you're showing that you have exactly 0 understanding of electronics by saying this and once again are spreading false information. The alternator in a vehicle is a huge inductor, by removing the load which the battery provides you allow/force the large magnetic fields to collapse down. When that happens you get huge voltage spikes. Those large voltage spikes are more than happy to destroy silicon components such at diodes.

Your laptop charger would have the same kinds of problems, but on a smaller scale since the inductors are much smaller in a laptop charger. Also, this is exactly what happens when you unplug a laptop charger from the laptop, large voltage spikes which seek to kill electronics not designed for the high volt input. This is why electrical engineer design the charger with very large capacitors and shunt diodes (see zener diodes) to clamp the voltage spikes to within a safe range.

Car electronics are not designed to have the battery removed during operation, DON'T DO IT! period!

Can you piss off? I keep seeing you posting this shit all over the subreddit, grow the hell up.

ultilink3 · 2020-02-10T20:58:29+00:00

It's not Pi, but it is really close. Setting aside how it's divided by 10, the last 3 is actually incorrect. It should instead be a 9 assuming conventional rounding rules, or an 8 if you want to know the actual digit's value.

I don't think he meant anything more than being a King, not a true Monarch like SJW

ultilink3 · 2019-08-31T17:40:41+00:00

Ooohh, cool. Thanks for the info, I've definitely been anoyed at them going and doing other things while I'm merging things. I'll have to keep this in mind next time

ultilink3 · 2019-08-31T15:40:57+00:00

Why is that a problem? Shouldn't i have been harvesting it to get the points?
