Hi, I recently bought an RX 470 to replace my old R9 280X, however, on my motherboard i'm struggling to find the latch to unlock my current GPU from the PCI-E slot.
I heard there are different types of locks, such as ones that need to be slided or held but i'm not sure which one my motherboard has.
My pc is kinda cramped, and the 280X is massive so i can't really see any switch on the motherboard and since I don't know what type it is, I can't really feel my way to it so I was hoping someone who knows more about this motherboard may be able to help.

The motherboard I have is an AsRock H81M VG4 R3.0.
