@neekir well thx to @promomei here your prof see how much important is temperature

@promomei perfect proff memory it not matter

his 45 C temp with 80 Power limit = 170 intensity = ~310 Sol/s = micron
my 61 C temp with 73 Power limit = 161 intensity = ~302 Sol/s = samsung
your 71 C temp with 74 Power limit = 145 intensity = ~260 sol/s = hynix
to get better result you need to lower your temperature to at list ~62 best case scenario for 80 Temperature Limit & for sure that is not easy for you be in india were humidity + temp are usual high from what i know .... so now i think you get it

Power Limit it set a limit what GPU it will goo base on Temperature limit set aka that 2 value are link togheter what are translated in I/s: = intensity / sec what influence Sol/s
@neekir set this Power 74, temp 80, core clock +160 , mem clock 0 , Fan: 75% fixed = you will get slice more
cheers
I increased core clock to 190, rest of the settings same, need to see it stays with out crashing, Thanks a lot for giving me valuable knowledge
Coreclock +190 mem 0 fan 75% fixed temp 72 power 74
