Getting close to FPS gains with a GPU that's been overclocked?
Getting close to FPS gains with a GPU that's been overclocked?
So I'm just starting out with overclocking and need some guidance. I recently purchased the Gigabyte RX 580 and discovered I can still boost my GPU performance even on a non-overclocked motherboard (H170). I adjusted the settings using MSI Afterburner as follows:
core voltage +24mV
powerlimit +40%
coreclock 1430 (+90 mhz)
memory clock 2100 (+100 mhz)
After running various benchmarks with all ultra games, here are the outcomes:
witcher 2 - sc 48 oc 50
fallout 4 - no fps increase
witcher 3 - sc 67 oc 69
heaven benchmark - sc 68.8 oc 71.3
I was quite disappointed by these results, as the improvements were only about 4%. I'm unsure if I'm doing something incorrectly and would like advice on how to safely enhance my overclock if possible. I also find it challenging to maintain a stable overclock at 1440mhz, fearing potential GPU damage from excessive voltage. The GPU temperatures are around 74 degrees both with and without overclock under load. Any suggestions or tips for overclock settings would be greatly appreciated.
My specifications are:
i5 6600
16gb RAM
RX 580 8gb
H170 gaming M3
500w PSU
2560*1080 LG ultrawide @ 75Hz
The RX 580 is reaching its overclocking limit, particularly for high-end models such as Power Color Red Devil Golden or Sapphire Nitro+. This is due to it being a very powerful RX 480, offering minimal performance improvement and little room for further tuning, with a maximum around 1500Mhz.
It appears typical, considering you didn't heavily overclock. The 2 fps boost with just 100mhz is unexpected, so raising the voltage might be advisable.
Try reducing the GPU voltage first instead of increasing it. Start with a lower base voltage and see if stability improves. Lowering the voltage usually boosts efficiency and performance. With a 1430 MHz base clock, you might not need much voltage at all. When I tried no voltage or power increase, the core clock stabilized around 1400 MHz without crashes—though my BF1 still crashes even with minor issues, so it’s manageable. I also noticed now that I can reach 1430 MHz without any voltage offset, but I missed adjusting the power limit earlier.
The RX 580 is reaching its overclocking limits, particularly with high-end models such as Power Color Red Devil Golden or Sapphire Nitro+. This is due to its already powerful base, offering minimal performance improvement and limited overclocking potential, with a maximum around 1500Mhz.

RX 580 is reaching its overclocking ceiling, particularly for high-end models such as Power Color Red Devil Golden or Sapphire Nitro+. This is due to it being a very powerful RX 480 already, offering minimal performance improvement and limited overclocking potential, with a maximum around 1500Mhz.
I had a thought about that. I managed to get it to 1450mhz using +42V, but it leads to crashes after about 10 minutes. Likely I’ll settle for 1440 now. It’s odd everything stayed stable at 1430 even with +0 voltage offset, but wow!
Other users have noted the difficulty in pushing these systems beyond their limits, especially when trying to reach 10mhz despite clocks exceeding 1400mhz. It's essentially hitting the upper boundary.
