Installed and tried for the whole day and lagging a lot while gaming, pc runs better without Afterburner.
Thanks a lot, this is also a kind of learning.
Maybe 5% was too much. Might have caused the card to throttle. Guess you could start at about a 1% bump and keep incrementing till it either throttles, overheats, is unstable, or produces artifacts. Might need to increase the voltage a bit to stabilize the GPU.
But you have two strikes against you with that card. 1) The lack of a cooling fan will make temps rise fast (might cause throttling). 2) That model uses DDR3 VRAM instead of DDR5 (slower).
