For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
Just like the Gigabyte Gaming OC, we again had real success overclocking the GameRock OC. Once more we were able to push the memory slider as far as it would go in MSI Afterburner, adding 2000MHz, with 180MHz added to the GPU Core.
This resulted in a real-world clock speed just shy of 3090MHz, averaging 3086MHz over our thirty minute stress test.
This resulted in some significant gains for the GameRock OC, as we gained 8% in Cyberpunk 2077, a rather staggering 12% in Horizon Zero Dawn, and an extra 10% performance in Resident Evil Village.
Power draw only rose slightly too, up to 305W, or an increase of 10%, which isn't bad at all.
