Firstly let me say that I love my new build (my second Ryzen 5 and personally/individually my 37th new AMD CPU - 6th running in my house ATM)!
I have an issue, though, and am not finding anything like it here, ASRock's forum or elsewhere via the Google machine...
Twice now after the system has come out of sleep I have had video/audio playback begin to stutter then the screen fills with snow/static and I have no choice but to reboot. This happened to me with an NHL game stream last night and my wife watching a x264 video played back in VLC tonight. From a reboot or cold boot the system plays everything fine.
Specs of the system:
Lian Li PC-A05FN
Corsair AX850 and RM650i
ASRock B350 Pro4 (latest BIOS - 4.70)
AMD Ryzen 5 2400G using the Wraith Spire (w/Noctua NT-H1 paste) from my R5 1600 box
CORSAIR Vengeance LPX 8GB (2 x 4GB) DDR4 3000 CMK8GX4M2B3000C15
Toshiba OCZ ARC 100 240GB SSD
Seagate BarraCuda 7200.12 ST31000528AS 1TB HDD
LITE-ON LH-20A1S 20X SATA DVD Burner
The OS installation was an upgrade from 64-bit 8.1 Pro to 10 Pro Build 16299 and has all the latest updates through April. Formerly I had an ASRock A770DE+ and Phenom 1090T setup in this case with an XFX R9 280X. Before upgrading the OS I uninstalled all AMD drivers from Programs and Features as well as ran the latest DDU.
After Ryzen'ing up the machine I installed the latest chipset driver (18.10_feb) and video driver for the 2400G (17.40.3701-feb12).
Things I've done thus far:
After the first encounter (after the Sharks game mind you!) I removed the AX850 in favor of a new Corsair RM650i.
At this point I'd like see if I can get any feedback from the community before I start hacking and whacking. The system is 100% stable running the following CPU/GPU benchmarks:
S.T.A.L.K.E.R. - Call Of Pripyat Benchmark (Ultra Preset @ 1080P)
Unigine Heaven 4.0 (can't remember the settings I settled with - will update here if anyone wants to know)
Unigine Valley 1.0 (can't remember the settings I settled with - will update here if anyone wants to know)

Reason: forgot to list storage under the system specs.
FYI did the following and will report back if this problem arises a third time:
Thanks for the reply. I was actually able to get this to happen from a cold boot for the first time. I let Heaven run for nearly three hours without issue, stopped it and left the system on. Came back to it hours later and started Heaven up again. Somewhere around 30-45 minutes into the loop the issue happened...
I went into the BIOS, set the RAM back to Auto, saved/rebooted back into the BIOS and changed it to the XMP profile BUT set it to DDR4-2933. Since doing that so far no problem.
While I wish Corsair made a DDR4-3200 8GB (2 x 4GB) Vengeance kit I can live with this as I wanted something low power but capable enough to play the litany of Steam games my son and his friends like + I expect Vulkan to take over here soon.
Ram can definitely cause problems. One of the most overlooked things people do is not buying ram off the motherboard supported ram list. Even then XMP is still an overclock and stability can vary. However since the manufacturer says it runs at that speed. You may wish to contact them. They might swap the ram for you with stuff that will work. Never hurts to ask.
Oh I know. Corsair listed it as compatible with "select motherboards" here: AMD Ryzen DDR4 Compatibility - The Corsair User Forums
In my Workstation Ryzen system I got the CMK16GX4M2Z3200C16 kit and it has been terrific. In this APU build I didn't need any more than 8GB of memory and I have no plans to OC since it's meant to be a purely media and mostly Steam gaming system so I went with see what happens. While running at DDR4-3000 the anomaly occurred but that was a possibility thus I am just fine with this machine running at DDR4-2933 given the $130 dollar difference between the two kits.
Welp same thing yet again. Wife was watching a video via VLC.
Interestingly, this morning, I saw a graphics anomaly adjacent my mouse cursor as it changed to the spinning wheel as I cleared Firefox's browsing history. Looked like a row of pixels 10-15 high/2-3 wide flickering. I cleared again and didn't see it but I tried to launch Heaven and it crashed immediately. Thereafter it ran fine and I was able to also run Prime95 (current build) for about an hour without issue each...
Somehow I feel like this will be resolved via a driver update but I am almost at the return window... I filed a bug with AMD and asked them to look at this thread but have yet to hear back...
That's the form I used ten days ago... Aside from an auto-reply I've heard nothing since.
Anyhow since yesterdays occurrence I have switched the "OC Mode Change Switch" from "ASRock Setting" to "AMD CBS Setting". Next I guess I'll try turning off CPB.
Would be nice if ASRock was up to the latest AGESA (I've seen rumblings that 184.108.40.206a is out) but to be fair to them I had an issue a while back with a since pulled update in which I had no video with a Sapphire RX 480 immediately after successfully flashing/rebooting the system so if they are double-checking such before release I am good with that answer.
