i installed Rx 560 4GD5 with my Dell optiplex 390 using riser card, drivers were installed successfully but when i tried to use GPU tester (furmark) it says that install graphics card with openCl 2.0
even when i tried to do some altcoin mining, none of the miners recognized my gpu. whereas windows device manager states that rx560 is installed properly.
my system specs are:
Dell optiplex 390
2 gb ram
dual core processor
H61 express lintel chip
800w power supply (purchased for this gpu specially)
solutions i tried:
Drivers: 17.10.1, 17.12.1, 17.7.12(provided with gpu) - unsuccessful
CMOS reset by jumper - unsuccessful
Display Driver uninstall (DDU) third party utility tried - unsuccessful
windows installation - unsuccessful
all methods were unfruitful, any help will be highly appreciated from you guys.
