Hi , thanks , your PNY gpu is power throttling.
IF YOUR GPUs Have 3 power inputs (3 wires / 3 power inputs) you should change your roms to EVGA FTW ULTRAs ROM.
You must choose the UNTOUCHED VERSION (NOT UNTESTED) just the evga ftw ultra OFFICIAL ROM. (Choose the newest one version of ROM)
Once replaced the rom , use core 1110 mem 2000 no power limit and fan 100%
Please come back after upgrade your roms as explained.
Show your results here …
IF YOUR CARDS HAVE 2 POWER INPUTS ONLY, NOT 3 , come here again we will find a compatible rom.
First upgrade all yours 3 power connectors cards to evga ROM
Be patient and CAREFULLY.
Upgrading roms take some time , please be patient do not disconnect power while upgrading
If you dont know how to change rom (force change) come back here.
I will wait your results, please post it here.
