could be an issue with a system overclock;   those test functions do work and haven't changed since day one....  They pass on my machines.

could be you need to get your amd.txt from v 2.7.x/2.8.x, and copy the optimizations to the new amd.txt generated by 2.9.0;  so be sure you didnt copy your old .txt files;  you need to edit the new ones.

I had to let mine redo the nvidia and amd txt more than once for some reason.


My test rig:
B250D8P I3-6100 8Gb
GTX 1070, GTX 650Ti, RX560

I did update my video drivers to the current version for Nvidia because of the security bug that was found;  and I left my AMD blockchain drivers alone as its been since I installed the RX560.

Ill zip up and upload the whole folder including my configurations directly from that miner;  and post a link in a minute.  You can see if its any different for you.


I do suggest updating the nvidia drivers though;  the security bug is a real threat; as well as I think needing the updated driver is a reality (I did compile under CUDA 10)
