The fourth machine is running some ati*SOG tasks and getting a respectable 156 Gflops processing speed. But the cpu processing isn't all that fast. The dedicated cpu processing machine isn't all that fast. I would swear I saw 30+ Gflops back on a cpu only machine in the 2200G listing.

Now that you mention it...almost all of the Ryzen 3s that I clicked on show higher (or, at worst, similar) average CPU processing rates than the Ryzen 5s. At first, I thought perhaps the faster GPU on the Ryzen 5 may cause a greater degree of CPU throttling, but this pattern holds even for the hosts crunching CPU tasks only. Interesting...

Hmmm... I wonder if this might be an issue with running 1 memory stick vs. 2 since these things are very sensitive to having "fast" ram access.

I upgraded the RAM in my APU machine from 1600 MHz to 2133 MHz about a month ago. I saw a small, consistent improvement in GPU processing (5-10% at most), but CPU tasks didn't change very much. Articles and benchmarks I read indicate that the RAM speed influences the GPU performance quite a bit, but I didn't come across any discussion about CPU improvements. I imagine the effect is the same as for any CPU: an improvement, but on a much smaller scale than for the GPU. If I remember correctly, having two sticks for dual-channel memory increases real-world speed about 15-20%...far from double.

After looking at various gpu tasks, I am wondering if anyone of these people are using anything on the command line and/or with the app_config.xml file?

I didn't see any when I clicked through some of those tasks initially. One would think hosts that do will rise to the top of the list. I can write a script that scrapes the task pages on the website to find one, but it hardly seems worth hammering the servers until these Ryzen users (many of them new) discover command-line tuning and finish enough tasks with them to produce meaningful data.

I agree it is not worth hammering the servers on this kind of curiosity.

I wonder if it would be considered "annoying" and contra-reg to PM nearly all the people on the two lists you created and invite them to this thread? I would be avoiding, where I noticed it, all the people who have added an external gpu.

I'm pretty new here, and to BOINC in general--you know better than I would whether that's appropriate in this community. Personally, I'd appreciate the invitation to participate and the chance to learn more about my hardware. I can't speak for everyone, though, and the opt-out nature of SETI's stats that I pulled the lists from makes this a bit of a grey area. Maybe you could first PM the users that show interest in participating (they already post to the forums or regularly crunch with several machines).

Well, that answers that. After about 5-8 PM's it said, "your not allowed to send PM's that often etc".

Oh well, I guess it wasn't meant to be :)

I'm getting close to buying one myself to play with. The Ryzen APUs currently crunching SETI really don't appear to bring out the potential of these chips. I highly doubt they're performing no better than my old A8, so I want to pick one up to measure for myself. On the A8-7650K, GPU tasks finish in about 35 minutes and my average processing rate is nearly 70 GFLOPS for SoG. From the two lists of Ryzen hosts that I posted earlier, I only found one with similar performance, and many look much slower. I can only guess that these users run other programs on the machine while crunching which slow down the the tasks.

I may wait for the upcoming Ryzen 3000-series APUs, though. I came across some articles while reading about AMD's recent release of the new Epyc "Rome" processors, and the platform looks very promising.

I am guessing but based on the reviews I have read, it looks like you need the fastest DRAM the CPU/MB will support and you need 2 sticks (I think it is a dual channel). If it is actually quad channel you would need four sticks.
And since the gpu will outgun the CPU cores, mostly, you need to tilt the processing to give the gpu priority. They basically said testing showed you can't have both OCed. Just one or the other.

From above "Of course, combining faster memory on top of an already overclocked Ryzen 2000 series iGPU is going to be the golden crown."

Are you thinking about the Ryzen 3 2200G or the Ryzen 5 2400G?

I am wondering if there are going to be any Black Friday "deals".

I have a case/PSU waiting. And I will be getting a ram upgrade so I will have some "free" ram for the experiment. So its a matter of choosing the one (cpu/cooler/Micro MB) you don't choose :)

Good idea...I forgot about Black Friday! I have a free case too, but no RAM--a shame that the memory will cost about as much as the APU. RAM prices these days...

Thanks for the link. The 5/2400G hosts from the stats export show poorer numbers than the 3/2200Gs, so I'm more interested in tinkering with the 2400G (more room for optimization, maybe). Looks like these support a maximum memory speed of 2933 MHz. I'll wait to see what Black Friday offers.

Ok, I will concentrate on the Ryzen 3 2200G prices and see if I can fit a budget around one.

Black Friday is tomorrow, and Newegg has the Ryzen 3 2200G on sale for $99.99. I haven't built a computer in a long time, but I am thinking of picking this up (along with the other parts). I'm looking to start small at first, but I want to get a motherboard that will allow me to expand to 1 or 2 GPUs, and with the AM4 socket I will be able to upgrade to a Ryzen 7 when the time comes.

I've been lurking on the message boards here the past few days, and I am still wrapping my head around what to do with the RAM. I understand that Ryzen is picky with the RAM. Apparently the 2933 is the minimum speed for the RAM, but a higher speed (3000 or 3200) would also work for this processor. Does that sound right? I'm also guessing if I upgrade the processor in the future I may need to upgrade the ram as well.

The ram is not just picky. :( It turns out it needs to be specifically labeled as being good for AMD or it needs to be identified as Samsung die-B.

If you are going to start by using the internal GPU you want the fastest you can afford (that is supported by the MB and the cpu) in at least two sticks. I think I remember this cpu/gpu as being dual channel so you will get a major bump in performance with 2 sticks.

I know of at least one Seti user running a 2200G/2400G who upgraded to a Gtx 1060 3GB(?) which are going used for about $150 on eBay.

Here is a "B-die" finder that will allow you to order "the best" ram you can afford. https://benzhaomin.github.io/bdiefinder/

Please subscribe here and tell us all about it. Another Setizen and I were discussing buying 2200G/2400G rigs so we could get first hand experience trying to wring all the performance we can out of AMD's latest APU (they have dropped the label for this latest generation).

Happy Thanksgiving.
And fruitful shopping.

I was reminded that I had intended this thread as a collection point for all the APU activity on/off Seti that seemed to be relevant.

Here is a thread from the Number Crunching forum under the Messages area: https://setiathome.berkeley.edu/forum_thread.php?id=83522#1964094

Thanks for re-posting here Tom. I was not sure if it was relevant to this thread or not and have always had great luck with the fellows in the Crunching message area. I guess I should have posted it here as well since you never know who else might be having the same problem.

But, since the topic is here now..... I wonder why I was unable to get the compatible graphic card to work with the apu. Any thoughts?

Which graphics card? And exactly what do you mean "work with"?

Hi Tom,

That would be a 6670 graphics card. I followed the instructions for setting it up on a BioStar motherboard and it just wouldn't take.

So when you attempted to use a discrete video card it would not be recognized? I wonder if there was a bios update for the MB available?

Same thought that I had, but I couldn't find one. I guess I'll check again though.
Thanks for the concern, it would make a heck of a difference.

Do you have more than one other discrete video card? Might try another one.

A couple of thoughts.
First - very rarely do normal consumer Mother Boards require a BIOS update to get a "standard" GPU working.
Secondly - where did you get the drivers for the GPU from? Over the years many have had "poor experiences" when getting the drivers from MS (by default MS will try and use those it provides, but all too often they haven't had the computational components loaded, only having the bits required to do with video stuff.
Finally - I do know that AMD GPUs have had a reputation of being very fussy the exact version of the drivers you need to install. Sorry, but not being an AMD GPU user I can't point you in the right direction.

Saying that - if the computer in question is this one:
ID: 6755144
AuthenticAMD A8-3870 APU with Radeon(tm) HD Graphics [Family 18 Model 1 Stepping 0]
(4 processors)
AMD AMD Radeon HD 6520G/6530D/6550D/6620G (SuperSumo) (512MB) driver: 1.4.1848 OpenCL: 1.2
Microsoft Windows 7 Ultimate x64 Edition, Service Pack 1, (06.01.7601.00)
it does appear to have picked up some work recently.
