ASRock RX 6600 XT Phantom Gaming D 8GB OC Review

Using Asrock’s Tweak software, you get 3 default profiles to choose from. The “OC” profile boosts the memory speed to 2100MHz base.

Our stock graphics score was 9740, and this takes us up 168 points which is a small, but notable 1.5% increase.

We also like to see what a card can do with a higher power limit, as this is often the bottleneck for upper-range cards. ASRock provides a generous 20% increase to power which a new TDP of 174W available maxed out.

This gives us a similar but slightly smaller boost than just the OC Mode gives.

Increasing the memory clock a bit at a time, we were able to claw our way up from 2000 Mhz to 2300Mhz.

This gives us a larger jump, up a touch over 5% from stock.

We tried boosting the core clocks up, but it really didn’t impact the score much at all as the card already boosts as far as it can go within its limits. We did check temps after about 15 minutes of stress testing and got the above results. We saw a max of 62C in the core, with it spending most of its time in the upper 50C range. Our ‘Hot Spot’ reached 81C. GPUz reports 127W used by the GPU cores, which appears accurate as our Nvidia PCAT system recorded total board draw in the 145W range.
