Well thanks for trying my advice out.

Most likely the gear was over clocked and tossing errors.

So you now help the card run at a more relaxed and error free speed.

Mining is so profitable right now that the only way to fuck up mining is to burn out the card.

My fear was you were going to do that with the 116% power setting.

 I have a rig with 3x 3080 cards.


Eth speed: 273.408 MH/s, shares: 904/1/0, time: 1:30

GPUs: 1: 91.497 MH/s (289) 2: 90.427 MH/s (295) 3: 91.483 MH/s (321)

GPU1: 64C 79% 222W, GPU2: 61C 77% 222W, GPU3: 53C 77% 222W

GPUs power: 665.3 W

note the 904/1/0 only 1 lost share as I make clocks gentler.

the cards do 91-93 each .  and just run

if your card can do a relaxed  25.5 and makes 1 of 500 errors

it is better than a stressed 26.5 and making 60 of 500 errors

more money  is made as 499/500 x 25.5 = 25.449 net on lower power

vs  440/500 x 26.5 = 23.32 net on higher power.


Plus killing the card is more likely at 116% power vs 100% power.

Same for ram.

 maybe 980 ram vs 1000
 maybe 900 ram vs 1000
 maybe 850 ram vs 1000
 maybe 800 ram vs 1000

great setting may be 95% power 950 ram or 90% power 900 ram

play with power

100% at ram of 1000,950,900,850,800.   so you  tested this at 1000 ram try the other rams

 then play with this one

 95% at ram of   "       "     "     "     "



 
then play with this one
 90% at ram of  "       "     "     "      "


then this one
 85% at ram of   "     "      "    "      " 


That is a lot of tests about 20 of them but even if you just do

100%. 1000 ram 950 ram 900 ram
 95%.  1000 ram 950 ram 900 ram


you will know you did some good testing. with 6 different settings
