I am testing a RX VEGA 64 8gb Sapphire Nitro for mining ETC.
I read an article that says that:
"Core Voltage (VDD) 850 Power Limit Watts: 210 or Percentage: 70%
Core Clock (CClock) Absolute: 1050 or Offset: 0
Memory Clock (MClock) Absolute: 2200 or Offset: +1100"
Using MSI Aftburner, the maximum memory clock value I can set is 1243.
Why do you think this happens? What can I do?
I am assuming you have read it on the Mining Chamber website which I agree is one of the best sources for mainstream overclocking of any of the modern GPU-s,however you have not read carefully that whenever there are two values like in the case you are having problems,one is for Linux the one with higher frequency and the other for Windows,so the best you can do is follow the overclock settings and put memory clock at 1100 for Windows.Do not bother going further as it won't give you a higher hash rate but it will bring you quite some crashes.
