Warning, nearly cooked my AMD Pro while the Orion was turned off

#1

Ok following situation turned my Orion O6 into an neat ITX build with a case, an ATX 550 Watts PSU from Chieftec with an Radeon Pro 8100, did some setups and testing today and when done shut down the system but did not unplug it.

One or two hours later I got a certain electronics smell in my nose (soldering tin) first thought something with the PSU (had this happen before) until I noticed a pretty noticeable heat coming from the case openend it up and the GPU was burning hot.

After it cooled down a bit i turned it on and a loud complain from the GPU (overheat beep) it went into emergency mode until it further cooled down, now everything seems fine again and hopfully no damage.

So system does not seem to turn off the GPU and it keeps running and heating up with no fan, really bad, when running it stays cold, but turned off it will heat up over time.

Clearly needs a firmware correction, will keep an eye on this, to help.

We are sorry for this issue. We can confirm that the 12V power on the PCIe slot can be controlled by software.

We are reproducing it now and will fix it as soon as possible.

Hello Jack,

Iā€™m facing the same situation, I want to insert a Radeon RX 6600 GPU and shur down the system. What will be happened?
When you update the firmware to disable the 12V power after shuting down the system, please think about the different OSs, for instance, Debian, Windows, Android, etc.

wait, why? normally the 12v line on the pcie comes from the PSU that will get turned off anyway, from where it comes on the O6?

You can power board using 12V barrel jack. Or USB-C port.

Sure, if you use ATX then it should feel safer as PSU should not provide power when turned off.

But this person was using an ATX PSU. I really dont understand how this can happen.

Well that was something I wanted to mention in another thread maybe, because after shutdown the Orion will NOT turn off the PSU but i wondered if this was just a typical quirk, my Milk-V Megrez does the same but so far it did not heat up the GPU I use there.

Hello Keldrim,
Just want to confirm with you, before you do shutdown system operation, your Milk-V Megrez board powered with ATX PSU? or USB-C adapter?

#9

Also powered with an SFX ATX PSU.

Got it, I met similiar issue.

Shut down Debian system doesn't work when using ATX PSU

Hi. We expert to fix it by updating BIOS.
The solution is to use uefi runtime to control the power enable pin.
We are still testing this.

CIX has provided a workaround for normal shut down, and we will test this soon.
