How do I set my GPU to be read in the MSI afterburner etc?
You don't need to do anything, just install MSI AB and it'll show you all the GPU settings + the monitoring graphs with temps, fan speed, core/memory clocks etc.
I have downloaded TECHGPU app but the readings do not show up when I ran it
What is "TECHGPU" app? Never heard of it, don't know anyone who uses it.
