AMD Radeon R5 340X OEM Dell 0Y7XRF,

Device Id:	1002 6610
Subsystem Id:	1028 0083

Clover recognizes it as R7 250 (it is definitely Board Number C870, but techpowerup states that it is Rebranded R7 250)

Nothing I tried makes it work

Definitely not usable with Mojave, there is nothing that can drive it

Bugger some R7 250 are based on Oland chip and some on Cape Verde. Stupid Amd. Check yours in GPU-Z

Got it working in High Sierra, if you have R7 250 based on Oland XT use Fake ID 0x682B1002
If you have R7 250X based on Cape Verde XT use fake ID 0x683D1002
I don't see any reason this won't work in Mojave
Very important is to deselect Inject Ati option
