Can thermal throttling cause GPU to lose hashrate? I got a used 1660 from someone and I've noticed that it gets hotter easier than other cards in the rig, also even when I tweaked the card to 50watt consumption it still gets 53°C while others are at 45°C, also no matter what I try with this card I can't get pass 21MH, it has hynix memory and I've used -502 and other but no luck, can the heat become the culprit here?
The gtx1660 has such a low hash rate on Ethereum. Therefore, for mining it is better to take the gtx1660 super.
If the video card overheats, then change the thermal paste, look for analogs of the MX-4, and the temperature will decrease by 2-5 degrees.
This is also a good purchase if you bought it inexpensively.
