I'm having issues with an RX 480 mining. Firstly I'm only getting a max of 22H/s, which I know is low for it, and secondly I keep getting these spikes that go down to like 17H/s, and it stays there for a bit then goes back up. Currently I'm just running base with base bios, but I tried a different Bios, and overclocking with Wattman, and I couldn't get any more performance out of it or make it more stable, does anyone have any ideas? I tried only mining Eth and not using the Dual mode, but it didn't help at all.
It's an MSI RX 480 Armor 4g on GPU0 that I'm talking about.
the 4 GB cards have slower memory, 22 is what they will do. 8 GB cards usually have the faster memory and will do 24.5. Bios modding will yield about 24.7 and 28 respectively. Core clock has very little to do with speed on Ethereum, but it will affect dual mining. Overclocking memory sometimes makes the minor slower because the card will use looser timings if it is not bios modded. To help with tips you can set the minor process to a higher priority in Windows task manager, or experiment with -dcri.It's an MSI RX 480 Armor 4g on GPU0 that I'm talking about.
Okay, so that solves that issue. I tried a Bios mod and it didn't seem to help at all, stayed at 22. It seems like I get 21 on average. Do you have any idea's about the fluctuating of the speed though?
I'm pretty sure that with a RX 480 4GB 1750mhz memory you should be doing about ~27 mh/s eth with modded bios and a bit higher mem speed. Modded 8gb cards with 2000mhz+ mem speed are capable of ~30mh/s. Depending on the coin, dual mining can take the speed down a bit as seen from my rx 480 1200/2100mhz dual mining eth/sc: https://gyazo.com/42527769f77e8672d3e85b61df651082 vs eth/pascal: https://gyazo.com/6024bbe014d3542edd0e41601ee73a5b(i'm running lower intensity with eth/pascal so that's why its still pretty fast with eth).
So i would say that something is wrong, and you should try troubleshooting it. Try changing drivers to the latest ones or Catalyst (Crimson) 15.12, try changing the settings on the miner and try other clock/mem speeds on your GPU to see if it gets faster...
