Temperatures & Overclocking
When my original sample arrived, I was disappointed in the overclocking ability of the G1 Gaming RX 480. However, it ended up being a defective card that Gigabyte was great about replacing form me. I had the replacement in about a week through their regular RMA process. Once the new card arrived, I updated the bios to version 7.00 on the Gigabyte support downloads page. After that, the card did a really good job overclocking compared to many other reviews I read on the RX 480. The G1 Gaming RX 480 I tested was able to achieve a +125 of a total of 1415 MHz on the core. However, this sample didn’t much like it when I tweaked the memory. I was able to get a +100 on the memory for an effective 8100 MHz clock speed on the Vram. It’s not the most mind blowing overclock, but it's given me an increase in performance and that’s what matters. Even with an overclock sitting at 1415 MHz, my G1 Gaming RX 480 never went over 79°c.
My temperate results for Hardware Monitor recorded a max temperature of 79°c. This while at 100% GPU Utilization.
Max Temp at 100% utilization was 79°c.
My G1 Gaming RX 480 hit 1425 MHz using the Extreme Gaming Engine.
