Title: Graphics input reduces mining hash power Post by: Mathero11 on November 30, 2017, 05:26:59 PM Hello,
I switches from my GPU graphics display (dvi to my dvi lcd screen) to onboard graphics (vga to vga) And when I had the display from my GPU, the mining performance was 30.3mh/s ETH and 1000mh/s DCR. But now I switched to onboard graphics and it reduces the rate to 28.0mh/s and 925mh/s BUT it consumes 10W less. Exact same settings for the claymore miner. Anybody know what the issue is, what I can do?

You should be able to overclock the card back to it's original performance.

But a little increased wattage I have now 2 cards running RX 580 nitro+ 8gb Dual mining 60.7mh/s and 2040mh/s consuming 385W (whole setup off wall) Is that normal?

Optimally, the GPU shouldn't pull more than 90W when mining, you can use software such as MSI Afterburner to view that. Keep in mind that it doesn't account for GDDR5s power consumption so the total power consumption of the graphics card is significantly higher than what software may display. |
