Decreased performance during overclock

[Docretier]

I tried overclocking my card without increasing the voltage to get an idea of what to do for when I do, but the overall score was dropping. Is it possible that instead of becoming unstable and forming artifacts that it just starts to decrease in performance.

When I was overclocking my card, the results I got in benchmarks would vary by overclock, sometimes higher, sometimes lower. I couldn't get it stable at +250 on the core without flashing the BIOS, which I didn't feel like taking the risk of doing so I'm happy at +245 core. I also had a pretty bad CPU bottleneck while testing overclocks, I haven't tried again since upgrading(I probably should).

 

Which benchmarks are you running, and what are your specs?

not a stable overclock back it off and try again and increase slowly

I wouldn't doubt I have a CPU bottle neck as well, I should probably monitor CPU performance alongside it. My CPU is an i5 6402p and my gpu is a rx480. I used Haven, could you recommend another maybe? Not that I have any problems with Haven but maybe getting a second would help in truly finding a stable clock speed.

I like Unigine Heaven and Superposition. My GPU struggled a bit with Superposition(might have been a bottleneck, not entirely sure).

How much are you increasing the clock? An unstable overclock will decrease performance, so maybe back off a bit?
