Sounds like it's a pretty good job. If you see any artifacts or have random crashes just dial the OC back a noth or two until it's perfectly stable.it was both. but then video says vram goes even further so i kept going
so at the end :
core clock +150 (155+ it kept crashing so i give up )
memory clock +1000 (idk why but it works fine)
core voltage +30% (idk if it does thing but as long as temps are fine im not gonna touch it )
Fan auto (max speed was 45 and temps 60-65c )
benchmark
