Unstable RAM OC, but only when using iGPU for decoding YouTube

[Zubkover]

Hi ppl, just a quick question

 

I was using my R5 2400G with a borrowed RX 580 for some time and nothing was wrong, no bsods, no errors, no nothing.

When I switched back to iGPU after giving back the 580 I noticed artifacting on YT videos - while using 2x speed on 1080p60 or scrubbing 5sec prev/next with keys. Artifacts range from missed frames to completly blank gray screen. But it happens ONLY on YT.

 

I suspect that it MIGHT be RAM issue? I have Corsair LPX 3000 CL15 RAM (set to either native XMP profile or same but with multiplier set to 29 for 2933mhz) but issue persists.

 

Da heck?

Does it happen if you set RAM to stock?

I would suggest to start by first uninstalling any existing graphics drivers via DDU and reinstall with latest available from manufacturer, esp if on Windows 10.

Then if problem persists we can go from there.

Already done.

I don't remember having such issues at stock.

 

Is there any way to force video decoding through CPU tho?

Since the issue is still occurring I would suggest you clock your RAM down to 2400. Ryzen chips don't always play well with memory that's clocked higher than this. While it may not be an issue in later BIOS updates or later board models, it's currently still a known issue.

Ab350mn gaming wifi on latest f22 nonbeta. So...

 

But still? Why? It's only on YT and only few channels. Like Gamers Nexus and Thatdudeinblue, but on LTT and Hardware Unboxed... No. Wtf.

It depends on what the BIOS on your board in combination with your particular CPU will work with. And it's a LOT more particular about it when using the iGPU. In any case if you look into it a bit you'll find that Ryzen 3, 5, 7 (Not sure about Threadripper) all seem to have selective issues with RAM that's running higher than 2400.
