Hi,
I do a fresh install Windows 10 and after that Boinc 7.6.22. When I look boinc logs I saw 2 ATI GPU but I have only 1 real GPU. Look at belove

How is that possible Boinc detected 1 more GPU ? When I try some projects like SETI, Collatz, Milkyway boinc start 2 wu at a time so GPU run %100 and windows become laggy as hell.

I try uninstall AMD driver, delete all with DDU application and re install again but nothing change. For my Nvidia GPU no problem.
Any suggestions about this ?

What ATi GPU did you think you had bought? Some models - both ATi and NVidia - have been marketed with two distinct GPU circuit boards in a single housing. BOINC would see each circuit board as a separate device.

I have sapphire radeon R9 270X it has only one GPU circuit so boinc must see 1 gpu but it shows 2 gpu as you see at first post.

There's also OpenCL CPU listed twice, with identical details. Maybe cleaning all drivers and reinstalling them would help.
