That's a strange issue, not sure what could be causing that. Are you sure it's nothing to do with the GPU? The only other thing is it could be a slightly unstable CPU overclock.

The Ryzen power plan just stops Windows shutting down or putting to sleep the CPU cores, as this is all managed internally by Sense MI inside the processor.

Yes exactly my thoughts, cant see how it could be the plan but I've reproduced it several times, very odd! The GPU is running stock and again if it was that I'd expect to see the problem using any power plan wouldn't you think?

I'll roll the CPU back to stock and try the Ryzen power plan again to see if thats the issue, but I've been gaming (inc. VR) for hours on end with it up to now and its been solid as a rock. Its possible though, I only tweaked the vcore to 1.34 to get the 3.8GHz OC what appears to be stable not touched the SOC voltage or anything else, so it may need a little tweak, especially running the Corsair LPX at 3200MHz.

Cheers.

Try upping the voltage a bit.

2 Questions for you

1) I have the latest Bios for my motherboard MSI X370 Gaming Plus
https://www.msi.com/Motherboard/support/X370-GAMING-PLUS.html#down-bios 7A33v53 - Improved memory compatibility. - Updated AGESA Code 1.0.0.6
But I do not see the ryzen power plans in windows 10 pro which is fully updated.
Is there a way to enable this?

2) Some How I bought RAM that can only get to 2993 - my ram is Corsair CMK16GX4M2B3200C16 v5.39 (Hynix)- bought from a famous online retailer who's name is like a south american jungle.
I belived this ram to be the samsung version and dual rank but its neither. So I'm thinking of swapping this for some 8pack Teamgroup RAM for ryzen its just, I don't think I can live with my pc For basically 2-3 weeks, while I wait for a refund.
So Will there be future realeases of AGESA mircocode that will address this common RAM at its rated speeds.
Do you know what imporvements will be in the next release of the agesa code, roughly when will that be.

Apart from that, I'm pretty blown away with my 1700 oc'd to 3.825 on stock cooler @ 1.375, SOC NB 1.2V & DRAM 1.35 - it very stable and makes short work of anything I throw at it. Gaming is som much smoother coming from my i7-3770k 16gb 1600 RAM

Any advice appreciated

Cheers

I wouldn't bother changing the memory for the sake of going from 2933 --> 3200, the actual real world difference in performance will be a couple of %, but will cost you time and around £50 extra.

It's also not the AGESA code holding that memory back, it's MSI's implementation of it.

That exact kit will already do 3200 on ASUS boards with their latest BIOS. I tried that kit myself last week and it would hit 3066 on my ASrock board. So the fixes are coming and with future updates that RAM will probably get to its 3200MHz speed on your board.

Glad to hear news about the RAM, i just ordered the same kit to my Asus board.

Ryzen power plan is installed as part of the driver update, downloaded direct from the AMD site :)

Sorry I didn't mention, I already have the latest chipset drivers that have the ryzen power plsn built in

But I still do not see these options in power plan options? Where Are they.

More info
1) updated my bios
2) I did a full windows 10 pro clean install and updated to the latest update
3) then I installed my amd chipset drivers, other motherboard drivers and gpu drivers.

I still can't see them?

Hey Matt a quick question regarding that power plan for you if you'd be so kind. I have the 1600 on a Gigabyte Gaming 5 mobo and specs as per my sig and I seem to have an odd issue with the Ryzen Balanced Power plan. Everything works nicely apart from when I leave it idle. After about an hour I'll either get a black screen which I need to physically power the machine off to recover from, or I'll find its rebooted and is sat at the login screen. I've done some troubleshooting and if I change it to the Windows High performance plan I see no issues. Any idea what this could be? I'm running a modest 3.8GHz OC but if that was causing the issue would it not happen with all power plans?

Might be worth posting your issue in here >> http://forum.gigabyte.us/board/12/amd-motherboards or here >> http://www.overclock.net/f/11/amd-motherboards
 
Anyone else noticed how confusing installing the chipset drivers for the Ryzen power plan is? Built a Ryzen PC last night and when I opened up the installer it greeted me with 3 options, the local driver (17.10 with the actual chipset drivers), recommended 17.4.4 and optional 17.6.2, the last two actually being GPU drivers with no chipset drivers and power plan.

Yes, it has been noted. @AMDMatt has passed this on to the software guys.
 
With over a week of data, I think the Passmark chart has settled enough to see how Ryzen is doing in Q3 so far for Passmark submissions.

https://www.cpubenchmark.net/market_share.html

As of now AMD share has gone from

18.1% in Q1 to
20.2% in Q2 to
23.8% in Q3 (so far).

Pretty good momentum. Just keep in mind Ryzen chips are more likely to be benchmarked right now. Steam Hardware Survey (a more reliable indicator of processors in actual usage) still not showing an uptick. I suspect it will only increase once Raven Ridge comes out as Intel still dominate laptops.

Steam HW survey is a terrible indicator of usage. It's only a tiny portion of the steam userbase, and those surveyed are randomly selected so it's hard to see shifts in hardware when an entirely different group of people are surveyed each time. Why they don't just collect data from all accounts to give a complete picture I don't know.

A random sample is fine.

If you have say 50m users, then even just a random sample 50,000 will get you very accurate results where there are 2 outcomes Intel/AMD.

I don't have binomial tables to hand, but it very quickly converges on the true value.

Think about it this way. We know an unbiased coin will land with exactly 50% chance as heads. How many tosses of the coin are do you think required to get that number to the nearest 1%? It doesn't take a sample of that many.
