Adjusting the settings on the Sapphire R9 280 OC does not change the FPS; it remains the same.
Adjusting the settings on the Sapphire R9 280 OC does not change the FPS; it remains the same.
About a year ago I built my third gaming PC. At that time, my CPU was an overclocked i7-4790 and my RAM consisted of Teamgroup 4x4GB, 16GB, 1600MHz. As games became more demanding, I decided to overclock the GPU. I used Heaven Benchmark and adjusted core and memory frequencies with MSI Afterburner. With a core clock of 1150MHz and memory at 1575MHz, my card remained stable without overheating (thanks to a custom fan setting). However, above those speeds it would become unstable, even though the PC didn’t freeze and the GPU drivers stayed functional. I observed around -20 FPS from the stock clocks. Have I reached the GPU limit? Is my PC unable to maintain performance given these specifications? My GPU specs are: CPU Intel i7-4790 at 4GHz (overclocked), RAM Teamgroup 4x4GB at 2133MHz, MOTHERBOARD Gigabyte GA-Z97-HD3 rev1.0, SSD Teamgroup 240GB, HDD 3x WD Caviar Blue 1TB. The GPU has stock clocks of 1250MHz (core: 940MHz overclocked to memory: 1575MHz core: 1150MHz). I have a power limit of +20% and cannot adjust the Core Voltage.
About a year ago I built my third gaming PC with an i7-4790 CPU and 4x4GB RAM at 1600MHz. As games became more demanding, I decided to overclock the GPU. Using Heaven Benchmark and MSI Afterburner, I adjusted the core and memory speeds. At 1150MHz core clock and 1575MHz memory clock, my card ran smoothly without overheating (thanks to a custom fan setting), but above that point it would drop to around -20 FPS from the stock clocks. I’m wondering if I’ve hit the GPU limit or if my PC can’t maintain performance anymore.

Voltage, that’s the last option unless you can modify it.
