Crossfire RX 570 nitro + overclock for a noob

[dillonbrownn]

forgive me because i am new to the computer world and really new to the (amature level? lol.) my current set up is 2 RX 570 nitro + running on a HX1000i, I dont feel like power will be my issue.. im trying to learn as well as set my rig up for best performance without skipping.. currently have ran at 1500mhz and it looks good up to 100 f/s but after it hits that it starts to skip for lack of knowledge of the proper word.
please help. i currently use valley and heaven as my benchmark

My advice is 1500MHz is far enough if not too far. You don't gain that much performance to be stressing your silicon that much. You are likely experiencing artifacting.

i have since lowered it to 1450.. what is the real benefit of crossfiring the 2 cards? with no artifacting at 1450

i raised my memory clock to 7800 mhz and was able to run core speed of 1500 with no artifacting.. i wish i had someone here to explain all this a little better.. im trying to learn from google so i basically have to shovel out half of it

The best way to see the difference is run some benchmarks yourself on actual games you play with and without the OC and crossfire. Crossfire is not supported by all games, so performance may vary.

1450MHz is a common OC for RX 570 Nitro+.
