update:
this morning I decided to use ddu and then install drivers again.
first I put only 1 rtx 3080 and then the second one. after some minutes, decided to connect 1 rtx 3060ti, but windows and miner does not recognize it... as I had not enough time for testing, I left the 2 rtx running.
hours ago again I saw with teamviewer that the pc was not running, so rig was freezed out completely and this afternoon my girlfriend had to restart it manually (I'm not at home out until sunday)
so, as the options are limited, I think I will install an specific miner os as some of you have recommended me. any advice about that? nvidia drivers are the same? I'm totally newbie with that
then I think will try 12 hour with only one card, then will add the second and test again 12 hours
important: where could I find the phoenix miner log? in the folder didn't see it....
I have other question, that never asked before, I hope some of you can give me some info about this. The story starts so many years ago, when btc price was about 30 dollars, I started mining with 2 dual cards, the top amd cards in that moment, and if my memory is enough good today, I remember that I mined 2-3 btc so easily.
I had in my desktop the .dat file and as all people told me that was pathetic and with no future, so as I was young, finally I sold the cards and stopped mining...
however, I think I had the file renamed and with the extension .dat removed (I thought someone could enter my computer and steal my wallet) in some place in hdd. Which is the easier solution to find a file like this in a hard drive: I have tried several ways but all times without success.
The miner is likely not going to be able to log the reason for the crash. You will have more luck looking thru the system log (use event viewer in Windows and look for hardware related events).
As for your second problem, you can download InfoRapid Search & Replace. With this you can look for a particular file in your whole computer. Widh you good luck!
