I just installed a new AMD Ryzen 2990WX and was expecting great things. It never seems to get over 20%. Each of the tasks are only at .3%. I have 32gb of memory so I do not think that is the problem. It is running Windows 10. In my profile for devices I have it set at 64 processors and 100%. I have ten other computers and they all run at 100%. Is there some setting that I am missing that is limiting CPU to only 20%.

How are your temperatures. Are you being heat throttled ?
----------------------------------------In the advanced view under options/computing preferences what are your settings there ? Cheers

Does the BIOS support the processor?

Try clicking 'Use Web prefs' under Options/Computing preferences to reset your local profile. It's possible local settings were being used before the processor was upgraded.
----------------------------------------In the device profile for the machine ... On multiprocessors, at most use: 64 processors On multiprocessors, use: 100% of processors

yes bios supports processor. MB designed for CPU and current bios

Does your version and level of windoze support this processor with SMT? I had a feeling that they had to do some work on it, but my memory may be faulty.

yes bios supports processor. MB designed for CPU and current bios I had a motherboard that had a AM3 socket on which was designed that version of AMD processors but as some of the higher end processors came out the mother board needed an updated BIOS to support the new processors. You still install them and run them but they didn't run right until the BIOS update was applied. Assuming your BIOS does support the processor, The next thing I would try would be to connect to another project like Seti or Einstein and see if the behavior is the same. Another thing would be to eliminate BOINC altogether and attach to Folding@Home and see if the same behavior exists. If so, it probably isn't BOINC it's in the hardware. Another thing I might try would be to only run one task and see if the processor runs at 100%. If so, keep increasing the number of tasks until it stops running at 100%. Might give a clue as to what the bottleneck is. If not, it probably isn't BOINC but something in the hardware. Just some diagnostic ideas... |

This is a well documented problem with Windows 10. If you want that beast to roar, you'll need to use Linux.

I change my cooling to liquid cooling, dropped my CPU temperature to 56C and now can get up to 85%. I am using windows 10 with all maintenance applied and have the latest BIOS. This MB was specifically designed for this chip. The article that Linux is better is interesting.
----------------------------------------Is there any kind of parameter for an AMD CPU that reduces processor based on heat? I have an Intel I9-7960 that runs solid at 100% but it does not have 64 processes |
