It’s hard to mod or find a good ROM that will work stable and high Hash-rate, after long run and work I succeeded to get 30+ on ethereum and 1225+ on verge. I have tested on my rigs, and I am mining Ethereum and Verge Coins on Claymore dual mining mode. I am using nanopool for now. I have used this ROM more than 2 months. It mines stable without stale shares. If you have same GPU, you can test this ROM out. (Be careful! If you are not sure about your GPU information, do NOT flash this ROM! You may put your GPU on brick mode and make your GPU out of warranty.
