first of all I am new to mining but i Have really very strange thing my card (gtx 1050 ti) clock speed base is 1303 boost is 1417 but after i downloaded msiafterburner my card is acting very strange it wont back to factory reset my clock speed now is crazy 1750+ without even play with any settings this is became the default for it . the real strange thing is my temp is very stable i dunno if that is normal or not i googled it and I know sometime the real boost speed can be more than what is advertised but not that much more we are talking about 300 mhz more . here is a screen .
You can see in the screen i only oc my memory but still my cpu get boosted even while it is on default .
Nvidia cards auto OC to the highest core clocks possible depending on the thermal and power limit headroom availible. Also 1700+ is a pretty normal OC on Nvidia current gen cards. This is why manually setting an OC on the core is pointless, because the card will automatically OC if the card is cool enough, and it will automatically downclock if it gets hot. You can not control that behavior.
Secondly and more importantly, dial the fuck back on that memory OC unless you want to wreck your card, that is too huge, you need to start at +600 OC, run it for a while to heck if its stable, and then increase by 100, and repeat untill you find the max OC that runs stable for atleast an hour of mining.
Also, reduce the Power limit from 100% to like 60% if you are only going to be mining Ethereum since you do not need the core to clock to 1700+ as it doesent improve Ethereum mining performance anyways.
Cheers.
