Hello all. I have a ASUS R9 280x and a few days ago I wanted to overclock it. I used the ASUS GPU tweak software that came with it to OC it to 1180 core clock and 6500 memory clock (I could have pushed the memory more at the time) with the standard 1.2V. For whatever reason it wouldent allow me to go much higher with the voltage or achieve the 1.3V that I see a lot of people have so I tried MSI afterburner and after slowly pushing it to try and get 1190 core clock I was unsuccessful due to that no matter the voltage increase artifacts would start to appear so I gave up on it. After toning down to 1180/6500/1.2 I went and did the heaven benchmark again (I did it once stock before I did any OCing and got a 53 FPS using ultra, normal tesseation, and 4x AA. I got 58FPS once I originally got it to 1180/6500) and oddly I only got 52FPS and that was after I pushed the memory a little further to 6600. No matter what I have tried I can not get the results of what I originally got and I have no clue what the issue is. If someone could lead me in the right direction that would be appreciated.

1fps in a benchmark is negligible, you could probably do 50 runs and get 52fps most of the time, 53fps a few times, and maybe even 54fps once. You won't get the same results every single time, no matter your settings and what you tweak.

but i did the benchmark at stock settings 1070/6400 and was getting higher results every time compared to now with a 1180/6500. Even if it does fluctuate it shouldent be constantly lower

Not all chips will OC (well). My 6870s can and will OC, pretty well. But what I find in game is a different story, actually lower fps than stock speeds.

Benchmark testing is great and all, but... if you can game, etc. perfectly fine maxed out, I'd say you're good. And with a new R9, I can't imagine you having any trouble.

When you're OCing are you stressing your GPU? When you're OCing a GPU I'd highly recommend using a program like FurMark to stress it as you OC. Continue using Afterburner.

Edit: how are your temps when OC'd and stressed?

I am using the Unigine Heaven Benchmark 4 to "stress" my GPU.

I identified afterburner was causing issues with the OC and was causing crashing of heaven and games. I uninstalled it, went back to Asus GPU Tweak and these issues are gone. Now im just trying to get a stable overclock. I was just running 1180/6600 on 1.2v and after a few games of BF4 i started to get artifcating (i think that is the correct term though when i see people show off artifacting occurring its major things, this was more of just a redish and greenish square like objects appearing for a second and then disapearing). I brought it down to 1180/6500 and the same thing occured, now i have brought it down to 1170/6400.
