Underclocking and overclocking occur often
Underclocking and overclocking occur often
You have your RX 570 mostly running in a significantly underclocked configuration for two main reasons. First, it keeps the system quiet, around 40°C when idle. Second, I rarely play games that need a lot of power, such as Rocket League or Forza Horizon 4, which don’t strain the hardware much. Despite this, I still achieve about 144 FPS in RL at full underclock and 85 FPS in FH4 at 60°C. Occasionally, when I want to play more demanding titles like Shadow of the Tomb Raider, I increase my overclock limit and bring temperatures up to a maximum of 84°C. I’m wondering if frequently switching between complete underclock and full overclock is risky. Please let me know.
It’s just like switching from idle to loading a game—it won’t cause any issues.
In 2-D mode the GPU slows down significantly, often reaching around 10Mhz or less. You don’t have to take any action to achieve a smooth and quiet performance when not running intensive 3-D games or GPU-intensive applications. However, under-clocking isn’t ideal for 3-D tasks. Instead, consider reducing the power limit—on an RX570 you could cut it down by up to half. The result will be similar: less heat and noise, but occasional spikes in clock speed might still occur during complex rendering phases, which can help prevent those brief stutters you notice.
Thank you for your message! It seems it's time to set up yet another MSI Afterburner profile, and your assistance is greatly valued.
It’s fine to trade more GPU power for reduced energy use and a quieter gaming experience in less demanding titles. Doing so in a balanced manner would likely be smart—slightly lowering the clock speed and power cap, and even considering undervolting. While Polaris isn’t widely recognized, Vega and Navi are, and reducing the maximum clock could still help. Keep an eye on the lowest FPS during benchmarking to ensure you’re not pushing too far.
I played a tough game with an undervolt setting from 1150mV to 1120mV. This was the only stable undervolt I've found; temperatures drop about 6C, which is good. But it only works with an underclocked preset. If I use stockclock, even -30mV still causes my PC to freeze during gameplay. I've seen others using an RX 570 and going to 1000mV (-150mV), which is stable for them, but in my case, even -30mV is too much unless the card is specifically undervolted. My RX 570 is an Asrock Phantom Gaming 8GB OC, I don't know the exact model.
