Colorful 3080ti on low hash #624

So I read ppl could unlock hash up to 90 then I bought a colorful lowest end 3080ti( u might haven’t heard the brand).

First I put it onto my 8 cards rig, the one with 8 cards motherboard, it could trigger the lhr lock easily and stuck at about 60 if I adjust settings in afterburner.

After that I test it on a normal motherboard, it could hit more than 80 and less likely trigger the lhr lock, but if I adjust any settings, it could go lower and stuck at a lower hash no matter how I adjust the settings.

The card is the 2 8pin version and I tried flash the other bios, but it didn’t help at all.

My friend got a galaxy has similar issue, anyone could give a suggestion?

Cheers

PG132 board PCB or the core quality issue。。。i think about 40%-50% PG132 board 3080ti can't reach above 85mh,you should monitor the core clock , usually those cards can't be locked in 1100mhz+

After flashed bios the best it could achieve is slightly near 86 by trex lhr 73.5, with 74 it just randomly hit the lock for some reason. And core is up and down dunno it’s controlled by auto tuning or the card bios

Usually fixed cclk provides the best and stable performance,few of those PG132 board cards can be fixed above 1100mhz.
