I crunched PrimeGrid first time with llr321 and i see very slow crunching on the AMD Ryzen CPU.
The Stderr output file shows :
' ... Using AMD K10 FFT length 720K, Pass1=320, Pass2=2304, 5 threads ....'

Is it possible to activate newer CPU-Instruction Set for the AMD Ryzen?

321 is a long file and ryzen quad core performance is between a skylake i5 and i3. Your run times do seem a bit long have you overclocked your 1700? if not can you? Also hyperthreading doesn't help at all with 321 typically and may be a hinderance.

LLR currently uses a slightly older version of gwnum that doesn't have Ryzen detection support in it yet. The newer versions do detect Ryzen and activate existing FMA instruction path. In my testing elsewhere, it doesn't actually give that much more, only a slight difference. When AMD made Ryzen they chose not to put in as much FPU resource as on Intel, so per core/clock, they do about half the work. As such, an 8 core Ryzen performs similarly to a quad core Intel.

You can try to optimise what you have. I'd run one unit at a time with 8 threads.

Like with Intel HT, AMD SMT doesn't help here.

So it's not only my problem? Hi I have just assembled a 1800x ryzen system and even if the Boinc benchmark said it's a litlte faster than my i5 3570k, real results are awful.
On project 321 the average time on the 3570k is 55-56.000 and the average on the Ryzen is over 90.000 Secs Run time and SOB project have the same problem with 150.000 vs 219.000 run time secs
The System is OK, temperatures are low thanks to the Noctua NH-D15. My motherboard is an Asrock x370 Taichi and don't have any problem, Ram are Ok, not the fastest around, just 2400 MHz but they worked fine on the 6600k I sold to buy the Ryzen.
This results are with using 50% CPU of both system, there's no OC. Now I will try to switch from Windows 10 to Linux just to see if there is an improvement or soon I'll sell this stupid CPU and go back to Intel. I had buy this system only for use it with Boinc and F@H and I'm not happy in both the projects, with my 980ti to have the same point that I had on the Intel system I have to left over 50 of the CPU free or PPD fall down fast.

It's not you. AMD hasn't been competitive with Intel (on this type of computation) for quite a few years now.

We won't know how good Ryzen is until LLR is updated with an updated version of gwnum.

There's no need to try Linux; this has nothing to do with the OS.

I can't tell you whether or not to return the CPU. Right now, Ryzen isn't going to help much because the software isn't there yet. If Mackerel is right (and I suspect he is), even with updated software Ryzen may not be much of an improvement over prior AMD CPUs.

Thank you very much, It was my fault, I was so happy to see again a great CPU from AMD and I didn't look if it was good for my needs before buying one :)

There's others here who (knowingly) bought Ryzen. You should be able to get good information about what it is and isn't good at.
