I have pre ordered a RYZEN 1700 and ASRock X370 Killer SLI mobo to replace my "old" FX-8350 and I cant wait to
see if this new AMD CPU will meet my expectations. They are simple. As many core as possible with the lowest
TDP possible. On paper this CPU as 8 cores, 16 threads and 65W TDP !

I am not running any CPU WU right now because the FX-8350 is really not good at it with high power consumption
and it is rather slow for 2017 standards. Right now it only drives the 2 GTX1070 (2 WU each) for a total
of 4 threads. It kinda runs at 50% and my corsair h100i v2 manage to keep it cool but I only see 4 tasks in the Boinc
manager. I am confident that the RYZEN will run 4 GPU tasks and 12 CPU tasks for a total of 16 threads (100%) and
runs cooler than the 8350 at 50%. I also expect better GPU WU completion time so I should win everywhere.

You have probably guessed by now that I am excited :)

I will keep informed about the CPU as soon as possible. I am sure many of you are considering this CPU but want to
wait for real life results before making the upgrade.

BTW if you do go for AM4 and have a liquid cooler like myself be aware that some models like my h100i v2 needs a
new bracket that corsair had just released. You can check if your cooler is AM4 ready on their website and order
the new bracket if you do need one.

If only energy was free... I could crunch 24/7...

Happy crunching to all of you !

See my latest thoughts on the matter in the CES 2017 -- AMD RYZEN CPU thread.

I think the 1700 choice will be a great price to performance ratio choice for you. Science apps are looking very good, even compared to i7 7700K. I think Ryzen 7 will perform quite well here at SETI running both CPU and GPU tasks simultaneously.

Thanks I will read it all for sure. I probably should have post it over there in the first place...
Amateur Astronomer like myself I see. Here I am also into Amateur radio so SETI is by far
my favorite project. I have crunched a few thousands classic seti WU back before BOINC.
Cheers.

Thanks. Look at the Ryzen thread here in NC. My latest post has links to third party reviews. Think the best review is by the Overclockers forum members. They bought retail hardware and didn't use the AMD press release kit that all the other mainstream reviewers used. Guess that is to be expected since they needed to post finished reviews when the NDA lifted.

Glad to meet another fellow amateur astronomer. Are you a visual guy or do you dabble in any imaging? Likewise, I am getting back into amateur radio now too. I had a Novice license back in the early 70's but never made it to General. I am just now finding out about the new technology available and am playing around with a SDRPlay RSP2 SDR radio. For now just listening in on SWL broadcasts and mostly the 80-40 m bands. Putting together some antennas to rig up. Have a end fed longwire strung up around the living room for now. Should be receiving a magnetic loop antenna from Great Britain shortly too. Have figured out how to get a short 20' mast up to anchor the longwire which will go on to a pecan tree higher up. It will also support the mag loop. Problem now is I'm incapacitated with a fracture in my knee that is limiting my mobility. Will be awhile before I get the antenna farm rigged up.

Thanks for the third party reviews it looks indeed very good for science. Wow I have looked at your astronomy pictures
Felicitation they are very nice. Looking at your telescope and the pictures you took you are more into the "pro" spectrum
of amateur astronomy than me. The only picture I ever took with my 8 inch reflector was the last blood moon using my tablet...
I have been on the field a dozens of times when I was younger but now working night shift and living in a big city I dont have many
good occasion to take it out and when I do I just look at the moon. It is still very emotional to watch the moon go by in the optics.
I have a lots of ham rigs here in the shack but I am not very active these days but I got my superior licence in 83. I mainly listen to
CW. I use to be radio officer in the merchant navy so morse code is like music to me. All my antenna are in the attic (dipole, isotron)
and I am running QRP when I operates.

Thanks for the praise on my imaging. I try. Still learning new tricks and that is what keeps me interested. Quickly put together my new Wellbrook Communications Active Loop ALA1530S magnetic loop antenna for a quick listen compared to my end-fed longwire for the start of the ARRL SSB DX contest that started yesterday. I'm impressed so far but need further testing. Just hooked it up in the living room but it will be at 20' eventually on a rotator and away from noise sources.

And now to get back on topic. Have you seen any of the latest news today about the problem with Ryzen SMT and thread scheduling in Windows? Looks like Microsoft and possibly AMD was asleep at the wheel in getting Windows patched properly for Ryzen. Seems that Windows thinks Ryzen has 16 physical cores and it treating it like an old FX processors. Explains why the single thread performance and gaming tests were so bad compared to Intel. Also explains why testers saw improvement when they turned SMT off.

Interesting articles over in the Linux world where the recent kernels have been patched to properly interpret Ryzen's microarchitecture. What I find interesting is some of the test results under Linux where Ryzen is performing in par with dual Xeon E5-2630L V2 processors. The pure math and science based tests pretty much blow away any of the current Intel desktop products.

Once Windows gets patched to work with Ryzen correctly and once the motherboard vendors get their BIOS' properly working with fast memory, I think the performance of Ryzen will be a lot closer to Kaby Lake in single threaded and game tests. Question is whether the release day reviewers will revisit the product and do updates of their testing when all the fixes are in place.

Ryzen is already working quite well in multi-threaded apps and doesn't seem to have any major issues with Linux with the latest kernel. I have still have high hopes for my Ryzen build for a major improvement in my RAC here at SETI and my other projects for my slowest computer which is what I am updating. I would hope that the Windows fix shows up shortly along with updated BIOS before I get all the parts I have ordered and haven't showed up yet.

Unless it is an application that makes use of AVX, in which case the AVX application clobbers the older applications, and Intel's AVX hardware implementation leaves Ryzen well behind.

I was referring to the Linux tests in my last post. I think it is well known that Ryzen doesn't really support AVX2. Not comparable to Intel. So would expect it to fall short of the latest Intel offerings for apps that predominately use AVX2.

Ok so I should not worry too much right ?
Here the motherboard that I have pre ordered is now "back order" and the Corsair's bracket status is "processing" so chances are It will be fix before I fire up the new system.

I'm in the same boat. No sign of shipment of my motherboard. Doesn't look like the Corsair bracket will ship for two weeks. I'm not so sure that Microsoft can move that fast in preparing an update for Windows to fix the scheduler problems. I would be surprised if they issued a fix in two months. Another reason to consider moving on to Linux.

I have a suspicion that the sudden dearth of any motherboard for immediate purchase might be because the manufacturers have pulled all stock back from the distributors. They might be in some wholesale campaign to update to the latest BIOS to fix the memory problem.

Apparently there is an issue where AMD forgot to supply all the details about the changes to the AM4 socket for Ryzen to all of the MB & cooling hardware manufactures.
I imagine that may be the reason some MBs are not shipping.

It's a case of "He said, She said."
AMD says they gave the manufacturers the details, and the manufacturers didn't follow the specs. The manufacturers say that AMD gave them the wrong information.
Maybe someone will eventually post the original & revised details and people can compare them.

Apparently the issue is only with some backplates that come with the motherboards having screws that are too long. After market coolers that come with their own backplate don't appear to be having the same issue.

Going to Linux is tempting... Never install nor run Linux before so there would be a lot of figuring out things in the process, but if it gets more out of my hardware (Ryzen/Pascal) I might give it a try. I guess I will have to re install windows after the hardware swaps anyway so it seems like its the right time to do it. I wonder what kind of increases in productivity we could expect from Running Linux ? I think there are CUDA apps out there that would make our 1070's shines like TitanX.

I have a lots of reading to do...

That is the same line AMD has fed before with the AM3+ backplates. The threaded inserts of the stock backplates by design stand proud of the top of the motherboard surface. Reason is that provides a locating function for the molded pockets in the plastic retention brackets that mount stock clip on coolers. That has caused issues before with after market cooler fastening systems that run out of thread or bottom out their fastening screws too soon and the end result is not enough spring force to achieve proper heat spreader to TIM interface clamping force. That leads to poor cooling. Have run into the issue myself. Simple fix is to put fiber washers over the backplate sockets on the backside of the motherboard between the backplate and motherboard. That takes up the slack and provides proper clamping force.

Of course the correct thing would be to design the backplate so that the threaded inserts don't stand so proud over the top surface of the motherboard in the first place.

That would allow you to run Petri's Special Sauce CUDA app which smokes every other SETI app published so far. That definitely would increase your productivity. You'll find Petri's computers and many others in the top of the Top 100 Computers in the Statistics pages here on the website running his app.

That is a pretty accurate interpretation of what I was told by my vendor yesterday (a major UK component distributor). The majority of the motherboard manufacturers had pulled stock, while for the others they were being faced with log-jammed phones to resolve BIOS issues.

Petri's single computer puts him into the top twenty contributors, and is a long way ahead of any other single computer!
"Tuning" for his app is very simple, set one value only, no great long command line to play with.

Yes electrical instability is being touted as the main reason behind mobo shortages (several small independent review sites have now already flagged this issue).
