1. Download HWinfo and check for memory errors!
  2. Start with stock clocks
  3. Then you can raise memory clocks by approx. 10Mhz steps, every few seconds
  4. Use MSI Afterburner or Overdriventool.
  5. Once you have some errors lower clocks a bit until there are no new errors. These clocks should be stable
  6. After you find the best memory clocks you can set core clocks (overclock or underclock) then you can try lowering voltages.http://www.pcworld.com/article/250644/how_to_overclock_your_graphics_card.htmlHWinfo – find your GPU and the GPU memory errors line. Watch it for numbers. If there are any after few minutes your memory clock is too high. If you have few errors after hours it’s no problem. But key is to have 0 errors. Memory errors can cause bad shares and may end up with BSOD

Some recommended clocks and voltages for RX cards – each card is different this is only for approx values! ETH

1120MHz 800-900mV
1240MHz 900-1000mV


Core clocks Voltages
