That a high memory clock for a bios modded RX 570, the highest mine can go is 2075 MHz, but that may be OK for a card without a Bios mod. Use HWinfo to check for memory errors. Ideally there will be no errors. If there are more than a few memory errors, you should lower the memory clock by 25 MHz until it stops giving errors.
please can tell me Where do I find the HWinfo ?
