So I had a brand new EVGA Gold 1000w power supply and with it I was getting a total of 1850-1900sol/s in EWBF across my cards. I just swapped it for a higher end EVGA Platinum 1200w power supply and now Im getting 1500-1600sol/s. NOTHING else changed. Any freakin clue whats going on here?
Well something changed, but you did not provide enough information to let us help you out.
I suspect you are using Nvidia, since you are using EWBF, and they are extremely sensitive to power changes and will throttle down if needed. However simply swapping out the PSU isn't likely the cause as much as maybe you have a loose connection somewhere starving a card(s) of all the power it needs. Another possibility is somehow your settings reset to defaults. A through description of your system and a list of what you have tried so far would help us to help you.
