That low temperature with low fan speed and max tdp, it must be good to have low temperature ambient… u live somewhere cold? Or is it air conditioned?
Air Conditioning… ambient is about 20C/68F
These are the new values! What do you think?
I will also buy an external fan to improve the ventilation in the room and keep it cooler since i don’t have air conditioning at the rig’s location and i have to keep the card’s fan speed over 80% for temperatures below 80 C
Hello @Zcash_Money! According to ur point: 3. Bump up memory clock to +500-600. Memory clock has the greatest effect in hash value. , memory settings -200 would significantly reduce Sol/s value, correct? And on the other hand memory +600 would increase Sol/s? I tried such options, but thee were no valuable increase. Could you post ur test specifications if you have. Thanks!
Try it for yourself - MSI afterburner settings has an option to unlock core voltage.
I am surprised no one mentioned a very simple and easy obvious thing to try first. Clean the heatsinks on gpu’s, clean off old thermal paste and reapply fresh new. I do this with every used card I buy and it significantly lowers temps. I have had cards go from 80c mining down to 64 from a good cleaning and fresh thermal paste. I bet any money doing this will knock at least 3-5c off those temps… Most of my cards run 82% fan, overclocked a little bit, and between 60-65c mining 24/7. No ac in area’s where the rigs are, and no fans running around area. I am using different cards than you, but point is if the cards are cleaned well and taken care of, they should easily drop temps over stock rated temps. Almost any card I have done that to will drop stock rated temps down about 5 degrees under full load.
doesnt doing that voids the warranty??
My cards are not used! I have new cards! I won’t do that since it will affect their warranty! 
Only if you damage the warranty sticker if you own one
