R9 380 Overclocking

[CobbleWalker]

Hello,

 

I have a SAPPHIRE NITRO Radeon™ R9 380 4G card and was spending the day overclocking it and I have some questions. I have the card currently at 1116 with no voltage or power tweaks. Higher then that, say, 1120 I get a lot of artifacting. So, I lowered it to 1116 to get rid of artifacting. When running heaven, the card slowly made it's way up to 1116, then boosted all the way to 1600, and stayed there for a good 20 seconds. I know GPU boost can have a large impact on performance, however 400mz is a little insane, or is it? After being stuck at 1116, I know you have to change the voltage of the card. My question is, what's the difference between power limit and core voltage, and what's the boundary on how far I should push them?

I doubt you even need to oc your gpu with i3 4170, and anyway.. you dont get much out of overclocking gpus.. you get a bit more fps.. but not that much... so.. If I were you I would check the clocks of 380x and set it to that.. cause thats probably optimal for 380
