Problem with a custom PC using WX8200


Recommended Posts

Hello dear all,

My name is Makoto TOKUNAGA from Laguna Hills, Inc., Dataton's partner in Japan.
We have been facing a problem for a while with our custom PC using WX8200. We would therefore like to share details of the problem with all of you to find out solution if any.

-----

We are planning to update the hardware of the WATCHOUT system where our custom PC has been installed.
So, we made a prototype of a custom PC using X299 motherboard + WX8200, however WATCHOUT does not work well.

As a symptom, the H.264 movie file always gets jumpy or freezes, also a bit jumpy even with Hap and MPEG2.
It is a pretty terrible situation, so we think it is not likely a tweaking issue.
However, it works OK with Windows Media Player and VLC media player without any problems.

In case of replacing the motherboard by X200 model from other brand, the problem remains the same.

In case of replacing the graphic card by RTX4000 from NVIDIA, it works fine with WATCHOUT... Very strange.

The configuration of the custom PC is as follows;
CPU: Core i9 10920X
MB: C9X299-PG300F-O
GC: Radeon Pro WX8200
OS: Win10 IoT Enterprise LTSC 2019

We want to use WX8200 because of synchronization purpose with others.

In case you have encountered this kind of problem, or if you can share any knowledge to work it out, please advise.

Thank you and best regards,
Makoto and on behalf of our Izumi HIGASAYAMA, my boss

Hi,

Additional info to our previous message;

We have already tested all of below mentioned versions by early June 2021;

Windows 10 - 64-Bit Edition/Radeon™ Pro Software for Enterprise, published for WX8200's Previous Drivers, Version 21.Q1.2 to 19.Q3:
However the symptom remains the same.

Anyway, we will obtain the said 2018.Q2 driver for our next test.

Best regards,
Makoto

AMD introduced some sort of power management in 2018 which will throttle down the speed of the graphic card when the system thinks that there is nothing much to do. Our favorite is still 2017Q4.1. We can't rule out though that a newer version of Windows behaves differently in combination with the various graphic card drivers.

Dear all,

Our test report;

We requested a sales distributor of graphic boards in Japan for the 18 Q2 and 17.Q4 for the Radeon Pro WX8200. However, they could not offer any of these versions, which are not open to public currently. The distributor themselves did not keep it either.

Instead, we received 18 Q3 they have. Therefore, we tested it just in case. However, the symptoms remain the same (the screen gets jumpy under H.264 and HAP format). As the launch date of WX8200 seems to be end of August 2018, 2017 Q4.1 for WX8200 might not exist.

Also, we compared MPEG2 movie (the screen gets no jumpy in this system) vs. H.264 and HAP movie (the screen gets jumpy) using log output function of the GPU-Z software and learnt that the GPU clocks were all approx. 1,135MHz +/10MHz, that means there was no big difference. We think it is not likely that the GPU clock goes down and gets into energy saving mode.

For your reference, when we played the same H.264 movie with Media Player, it was very low value such as 65MHz +/5MHz, however the screen was playing OK without getting jumpy at all.

Appreciate your comments, if any.

Best regards,

Might be that the WX8200 is not supported in the 17Q4 driver. If you want to give it a try you can contact me for a download link to my server.

WATCHOUT uses different decoders than the Media Player which can lead to different quality. To really analyse the problem opening a ticket at the support page might help.

Dear RBeddig,

Thank you very much for your information and kind offer. Yes, we would like to get the said link to your server to download it for our internal test! We will get in touch with you by separate email.

Regarding a ticket at the support page, we once got it and exchanged views... However, they recommended we post here to monitor advice widely from other partners.

Best regards,

Makoto

Dear Rbeddig-san,

We downloaded the 2017 Q4.1 and tried to install it. However, sorry to inform that, probably because it does not support WX8200, installation was not completed... so it did not work as expected.

Please provide comments, if any.

Best regards,

Makoto

Dear Rbedding, dear Bambam, dear Jochri,

We just discussed internally and came to conclusion that, we should give up to use WX8200 and replace it by RTX4000 instead.

Thanking you very much once again for all your advice and kind support extended to us in recent days.

Best regards,

Dear MatzeLe-san,

Major problem here  is that, we do not know exactly, with which parts it should work or not.
So far, the cause is unknown.

In early days, we purchased X299 motherboard + WX8200 and tested, however, it did not work.
After that, we tested several parts combination, but never got good results when using AMD.
For your information, our test results as attached.
We did not try other combinations, unfortunately.

Best regards,

Makoto
