Hi everyone, I've caught interest in cryptocurrencies a while ago, but I only read and thought about it.

Now I've decided to give it a try on my current oldish rig, just to get a bit more familiar with it, and possible gain some change.
I'm on windows 10, latest drivers, with an XFX 7950 mining with Claymore's dual miner for ETH +DCR/SIA etc. (version 9.3).

I'm mining in dual mode, Ethereum and Decred, and my hashrate is pretty low, around 10.5 Mh/s for ETH and 325 Mh/s for DCR, where I should be getting around 16-18 for ETH, and much more for DCR (I can't find exactly how my card is supposed to perform here, but apparently more than 1000 Mh/s).

Now, I've already tried rolling back drivers to 15.2, or whatever is the version that Claymore's miner is suggesting, but it didn't change a thing.
I've also been mining on the same pools (nanopool for ETH and Suprnova for DCR) for a couple of days now, but the rate hasn't increased even slightly.
Also overclocked the gpu a bit to squeeze more performance out of it, around 1025 core and 1450 mem.

Is there anything else that I can do to increase my hashrate, or is it actually where it should be?

I'd rather not use a dedicated OS for mining, since I'm using my only desktop rig to just "get something" when I'm not around to use it, but maybe a docker could help?

Thanks in advance
