What is the safe voltage for Polaris?
Hello, I'm adjusting a 480 Nitro+ into a 1366mhz 580 setup and need to boost the Vcore for stability. I aim to get the GPU above 1400mhz. What's a suitable Vcore setting? I've set power limit and vcore to maximum in afterburner, which gives me 1.25v—does that work safely?
In my experience, 14nm Polaris offers a decent voltage tolerance. I've tested it up to 1.5 VCore at 1567mhz on very cold water around 5°C—definitely not ideal, but not impossible unless you're willing to risk damaging your card. Running at 1.25V is safe for regular use, 1.35V is what I usually choose daily during overclocking, and 1.4V might be best if you're benchmarking or just having fun.
The challenge with overclocking Polaris lies in its Power Target. At 50%, it's restricted to roughly 270-280 watts. If you run at 1.3V with a core between 1480-1500, you'll consistently hit the target, which lowers the Core Clock. Keep an eye on HWinfo and monitor the card’s power consumption during gaming or benchmarking to discover the optimal balance where performance stays stable without sacrificing clock speed.
