Log Why do cases for an APU-Build (no graphics card) Suck?

[PVC]

Yep, I also thought they were stock. Until I found a seller who said "Mine are standard. No splicing" as a reply to my inquiry about why his (Delta Electronics DPS-350AB-12 350W Server Switching Power Supply) had less cables?

Pfft. The power supply 24-Pin motherboard cable is only 3-inches long. An extension could work but then I would have cable management issues because the 24-Pin hard-plastic connectors don't route well. And, the 24-pin is SPLICED! Just shorter. So I returned this for a full refund including shipping, and including return shipping.

I loaded this up with heavy duty UTube videos, and flipping from one website page to another and it doesn't seem to mind the heavy graphics work.

But when I am typing in the Chrome browser (a reply post as example) my typing will freeze, and it will stall for many seconds, and then it will revive, or it will show a black screen, and then revive. I have a help ticket started with ASUS mobo support.

Have you checked the Windows Event Viewer system logs to see if there are any display driver crashes? The black screen/revive pattern is very reminiscent of that.

As for the hwinfo values, looks mostly as I would expect except for the TDC going to a max of 149A. Do you still have some kind of default on for PBO?

65W TDP processors I thought defaulted to PPT 61-88 max, TDC 60 A, and EDC 90 A, at least they did for Zen 4. Some light searching on Google and Google AI is saying it's 150 A EDC for AM5 but I can't find any reference for this.

Answer from MS support;
Based on your description, it seems that your black screen issue might be caused by a crash in your graphics card driver.

This appears to be a somewhat common occurrence with AMD graphics cards (I used to encounter this issue frequently with my 5700XT).

The problem seems to be related to the high power demands of the 7900XTX. Some users of this graphics card have shared solutions online,

suggesting that reducing the maximum power consumption and frequency of your graphics card (which you can do using the AMD

graphics card driver) can significantly improve this situation. If you feel that this solution is not suitable,

I recommend contacting the seller of your graphics card for a replacement or trying a higher-quality power supply.

Ok have you tried installing the latest Adrenalin package from AMD? You can just choose a drivers only install when you run it to skip the extras/bloat.

I was avoiding the Adrenalin package download because I don't do any Gaming.

However (and after an image backup for possible recovery), I installed a (drivers only) Adrenalin. As I understand, because it is (drivers only) then I don't get access to any Adrenalin settings for adjustment.

However, (with Adrenalin installed) I just got another freeze, and now a second freeze as I am typing this.

Now there is even a modular 600W from Enhance (@Overtek ). The more power the merrier - and potentially lower fan noise, too.

HMm; Is it too soon to be thinking about a new Flex ATX power supply/PSU?
Looking at the Overtek 450W and 600W Flex ATC PSUs linked by @hrh_ginsterbusch

The 400W is slightly longer by half an inch (15mm) or so. See below for the summary of specs I collected. The Noctua fan option seems desirable to me. But I don't understand this statement? "*Note with Noctua fan option maximum ambient operating temperature at full load is 25°C. Under Noctua fan, the loads be kept to a maximum of 450W."

I'm not sure a new PSU would solve your crashes if it's just driver related. But if you have another PSU, even if it's SFX or ATX I'm sure you could just put it next to the case and run it off of that PSU to rule it out.

Overtek does a lot of extensive testing. (You can check out some of his PSU work on Youtube https://www.youtube.com/channel/UC27MuZGXETYgQwBJbh-6F1A).

Basically it means with the Noctua fan swap it is not recommended if you live in a hot climate with ambient regularly over 25C /77F as it may not adequately cool the PSU. And the second restriction similarly related, that if you know your sustained loads to be over 450w, then again the Noctua fan swap may be not be advisable.

BTW you may have to dig in to troubleshoot the platform/8700G issues. Seems other users have hit dead ends trying to resolve similar:

ASUS PRIME B650M-A WIFI II with Ryzen 7 8700G freeze when Adrenaline is installed

New system build with ASUS PRIME B650M-A WIFI with Ryzen 7 8700G and DDR5 32GB. No GPU card, planning to use the 8700G APU for the graphics. Running Windows 11 Home. System keep freezing from time to time, even when there is no load after installing Adrenalin 24.4.1 Had also tried next lower...

[SOLVED] - 8700g screen black

My screen randomly goes black. Asrock x600 deskmini 8700g Corsair 1x16gb ram 4800MT/s DDR5 Teamgroup 1tb nvme ssd gen 4x4 I have the latest bios. The drivers downloaded automatic from asrock.

forums.tomshardware.com

Yours doesn't seem quite as bad since it's something recovering but if you have Ryzen master installed you could try lowering the clock of the integrated GPU. If it stops the black screen/recovery then it sounds like an RMA might be in your future.

Check out this thread https://community.amd.com/t5/pc-processors/ryzen-8700g-780m-black-screen-problem/m-p/693924

Have you tried clocking down your memory to 4800mhz even though they're rated at 5200?

 

[PVC]

The memory is already 2400-Mhz. Also, no setting has been increased by me from standard default values. I have a few days left for Amazon return. After checking with AMD tech support tomorrow (I already have a support ticket with ASUS) I may return the entire system (frown, I also lost the tools atop each forum post.).
ETA: Edit to add. I got the SSF forum post tools back after using another/different computer.

Thanks for your help!

"*Note with Noctua fan option maximum ambient operating temperature at full load is 25°C. Under Noctua fan, the loads be kept to a maximum of 450W."

The issue is that the Noctua fan cannot sustain the same high rpm as the original one, and thus also not adequately cool the PSU past the 450W, esp. in less climate-controlled rooms or areas.

I've read about it in other threads, IDK if it was here on SFF.net or r/sffpc, but somebody has been extensively researching this topic, and found out that eg. the FLX version of the Noctua fan is better usable for the purpose of PSU cooling, but also a certain cooler brand is best to both achieve near-silent operation, while being able to keep up with the required RPM load. Gonna post it here / edit my reply if I find it; I might have bookmarked it or sent it to myself on Telegram.

Alas, doesnt change the fact that albeit the Noctua fan allows for much improved noise levels, its a less good fan for cooling a PSU.

cu, w0lf.

Yep, an Internet search for (reddit 8700g black screen) brings up many/many similar events, thanks @vinnyoflegend

One person said reverse-the-ends of your hdmi cable to your monitor, which doesn't make much sense, except that it may somehow cause your monitor to reload drivers and such?? So I did that, just to be thorough.

Also, this doesn't seem to be related only to the Ryzen 7 8700G, or even only to the Ryzen 7 series. So maybe I need to be patient and wait for these display/monitor issues to be worked out?? After all, and as a non-gamer, I am not asking for much with this APU build. I just want a snappy, non-black-screen PC.

I don't think this is related to my power supply. Everything is running fine today, low fan, case is cool to the touch.
Oh, wait. It always starts out running fine. Then with simple reply to forum topic tasks, it goes black screen.

I think I found a workaround! Unplug/Replug the hdmi cable, then it works fine for an hour or so.

AND, If per chance this was related to my $10 (Delta Electronics DPS-350AB-12 350W Server Switching Power Supply) then why would this workaround cure the black screen problem for a while?

 

[vinnyoflegend]

One other thing, if you're actively using this PC to browser, is your main browser Chrome or Chromium based? There is a Radeon issue that's exactly like this (intermittent black screen) if you have the browser open during these issues.


Navigate to chrome://flags in the address bar, search for "Choose ANGLE graphics backend" and select the option D3D9, restart your browser when it prompts you.

My wife's PC had this issue all the time with an RX 6400. I believe the workaround worked, though I eventually switched her GPU to an RTX 4060 and it definitely hasn't occurred since.

 

[PVC]

Okay Thanks; I am trying that fix;

• Paste "chrome://flags" into Chrome browser URL and press Enter
• Scroll down to choose "ANGLE graphics backend"
• Use the Pull-Down menu to Select "D3D9"
• Restart Chrome Browser
• and for good measure, restarted the PC too

 

[PVC]

Though, I am concerned that will affect my graphics speed? I think I already notice a lag in loading some web-page images where these were (snappy), not lagging before. But I will continue testing for a while. It has a warning;

Yep, that "Kludge" seems to fix; or at least halt my AMD 8700G Baack Screen issue.
Bit I'm still not happy. In Chrome and (even in Notepad, without using Chrome Browser), when I type a single quotation mark ", nothing happens, then when I type a second quotation mark it displays two quotation marks "".

Even if I wait a long time after typing a single quotation mark ", nothing happens until I type the next character.
Same thing happens with this one other character (^^) in both browser and notepad?
