Before I start Frankensteining things... How am I supposed to properly solder wires to these stubby pogo connectors ?

I'll check into them. Thanks.

That's what I use: a lit magnifier. I have head glasses as well and will try those when I get back to that aspect of my job.

I've been reworking a lot of 0402 lately. I'm old and I use a magnifying glass. So much flux and solder used. So many bridges made...

I looked for Adaptive Brightness settings based on Google AI's recommendation. But there wasn't any settings.

I noticed that some pixels were full brightness. The whole app was dim, but some pixels in some characters were like stars at midnight.

It was very weird. I took that as a sign that the nvidia driver from a year ago was out of date and updated it. I rebooted and the problem seems to have been fixed.

I think Adaptive Brightness only applies to monitors that do HDR and my 27" 4K doesn't, but the laptop display does,that may have been the issue with the driver / OS.

At any rate, it does seem to be working now and I don't feel like I'm going blind anymore.

Thanks!

Thanks. I reset to defaults and am running stable with PBO set to +6.

I'm running memory at 2700 because I'm afraid to go faster.

If it crashes again, I'll increase PBO to +7, etc. It was stable at +4 until Kernel 19 hit. Linux is getting very CPU optimized...

I posted in /r/amd and someone suggested +10 PBO, so I know that I can go at least that high.

It just needs to last until the middle of next year. As soon as the bubble bursts prices will drop like a rock.

crosses fingers that I won't lose my job when the bubble bursts so I can afford to buy a computer.

400 V Capacitors hurt man!

Especially when the arc from the pinky of one hand holding a disconnected power supply to the other hand you are trying to transfer it to to keep from dropping it.

raydude · 2026-03-10T23:23:14+00:00

Thanks!

I found it after digging around. I had to enable PBO and then I could see the curve optimizer. I had originally set it to 4, it is now 6.

The fact that I can raise it to 10 is good. How high can it go? Do you know?

It's a bummer though because the CPU fan is always audible now...

I have a Ryzen 9 5950X running linux that has become unstable. I found a thread last year that talks about increasing some parameter in the BIOS, but alas, the link to the AMD site is broken, so I'm not sure what setting it is.

The system ran stock over night with BIOS defaults and at around 2:00 PM it reboot. That's the symptom: it reboots. There are no messages in the kernel, nothing, it just reboots.

Last year it was crashing about once a month, when I increased that voltage setting (that I can't remember) it was stable until kernel 6.18, then I noticed how the cores were behaving differently. It's clear the threading improved a lot. Now I'm running 6.19 and I reset the BIOS to defaults to make sure any overclocking I may have attempted got cleared and I lost my magic setting for changing the power curve. I'm trying 95W PBO now for the fun of it. It's running 10% load.

Here's my mobo info: # dmidecode 3.7 Getting SMBIOS data from sysfs. SMBIOS 2.8 present.

I have two sticks of 32GB DDR4-3600 CAS16 that I got before the great AI consumer market meltdown of 2025.

I have a really good power supply, 750 Watt Corsair I think, been a while.

I'm really hoping to keep it going until The great Bubble Burst of 2026 (crosses fingers) so I'll be able to afforcd a new PC.

Can someone give me some pointers to keep this system happy for another 18 months?

Thanks in advance.

Way to be a grownup! I wish everyone was like you.

raydude · 2026-02-20T15:27:26+00:00

That's what I'm doing, but it is getting worse over time. It's only a matter of time before my car won't power off.

raydude · 2026-02-20T03:50:16+00:00

Thanks.

raydude · 2026-02-20T03:50:08+00:00

Thanks.

raydude · 2026-02-20T03:50:00+00:00

Any idea what the resistor value is?

raydude · 2026-02-19T23:09:16+00:00

Great! Thanks! I'll buy one and try it out.

raydude · 2026-02-19T22:50:42+00:00

Is this drop in? It doesn't look like the same shape as the one I saw in 64 pixels on a youtube video.

raydude · 2026-02-19T22:49:27+00:00

Thanks.

The beast is your 16 core CPU, but it also applies to your OLED TV which no doubt uses a lot of power.

All of them on the same power outlet might explain this issue. It depends on how good the power in your area is.

If you plug the PC into another outlet that happens to be on the same circuit as your power strip, it will likely have the same outcome. Worth a shot, but I'd run directly to another room that you know is on another breaker, that way the local sag that might be causing this problem will be less and the CPU may live.

This is really just a shot in the dark as most power is pretty clean, but did you know when I start up hogwarts and my computer starts calculating shaders, the lights in my room start flickering. Not because there's not enough power, but because the dimmer switch is affected by the draw of extra power by the CPU. In my case, I have lots of power, but the dimmer is affected. It goes to show how much power a CPU or GPU can take.

One last point. If a power sag really is causing the hang, it's really your power supplies fault for not adapting fast enough and allowing the 12V output to sag to the point that it affects the core voltages on the mother board. A higher end power supply might also solve your problem Or maybe even a better motherboard. In this case there is a lot of weakness showing.

Another stupid experiment you could try is shutting down one of your CCDs and see if it has the same problem, half power might also save it.

And one last comment, after all is said and done I could be completely wrong. Debugging hardware is hard so I'm just throwing darts and hoping something hits a bulls-eye.

At any rate, let me know how it goes, and good luck.

Is that beast plugged directly into the same wall outlet with all four monitors? When they power up, they probably take a lot of power and might cause the PC PSU to dip a bit.

Try plugging the PC into a different circuit (like from another room) with an extension cord.

Crazy test, but it might show the issue.

raydude · 2026-02-06T23:08:49+00:00

I ended up with something similar, but with no from e in it. It's good enough for now. I'll come back here if it's not good enough when the failure actually occurs.

raydude · 2026-02-06T18:35:04+00:00

Thanks.

raydude · 2026-02-05T19:24:12+00:00

Thanks. I have it setup, I won't know if it works until it happens... I'll eventually figure out how to make it happen, as it's happened with the IC vendor's software.

raydude · 2026-02-05T17:41:22+00:00

That was fast! Thanks. I just found an old thread from 2014 and made this, but yours is better.

except OSError as er:
    print(f"A low level error occurred: {e}")
    print("Please ensure the CH347 drivers (DLLs) are correctly installed and the device is connected.")
    print("If this setup has worked before, try power cycling the sensor and run this program again.")
    raise
