Great update, the new base system uses half the power of the previous i5 4590T/H97 setup! When idle, it draws about 80W, dropping to around 40W during mining pauses. I added 40W from the cards but only increased wall usage by 10W when mining. The combination of a lower base system and a more efficient power supply keeps hash rates unchanged.
Currently? The 40W higher cards draw more power before the PSU because the latest NHOS version isn’t working properly and doesn’t match my custom limits or speeds. My wall draw is only slightly higher than before. I’m checking the old image to revert to previous settings so I can restore my power caps and clocks. Also, I’m facing problems running more than two cards at once due to PCIe lanes and switches on the board. Maybe a multiplier will help, but I haven’t gotten a response to my thread about it yet.
Increase each card's output by 40 watts? Yet cutting a bit of power from the GPU is essential? Consider lowering the cards energy use too? Only a modest extra 10 watts from the wall seems like a lot. Great effort!
20W boost per card adds up to 40W overall. Each card should run around 100W, not 120W, and you should be getting 30-31MH/s from one and 25MH/s from the other at that point, not 29 at 120W and 24 at 120W. The extra 20W on the blower 1070 means more noise and heat coming out, which isn’t a big issue for the RX580 Red Devil. I’d prefer having my 40W back and my hashes back instead.
