I have an 8x MSI 5700XT Gaming X platform. I have done Memory Toimming in all of them modifying the BIOS, and I get 54Mhs in each of them with memory at 1750.
The problem is when I try to increase the OC speed of the memory, to obtain a greater number of MHS, my Rig crash in random times, sometimes a few hours, sometimes many hours, sometimes a matter of minutes ... there are times that one of the graphics cards is placed at 0Mhs and within a few seconds the PC crashes, Other times PhoenixMiner gives an error with a lot of hexadecimal figures and freezes, and every few hours I have to restart the PC and restart everything.
I have even tried leaving it at 1750, and it has lasted 55 hours without stopping giving 54Mhs per GPU, but in the end it has frozen.
I have the power set to -46% and the consumption of the GPU is 113W each.
Could you tell me how to leave the rig stable?
Thank you very much
with the level of modifications you have I doubt there will be a way to keep it stable
as the bios is modified and the card is running with custom bios
it can crash anytime when there is an error
I will recommend leaving it 1750 and setting a bat file which will reset the miner every 24h with 10 mins gap and see if that keeps them stable for longer
