Sapphire RX580 Nitro+ OC Samsung Modded ROM (30+ Mh/s) – Notes from a Programmer

Sapphire RX580 Nitro+ OC Samsung Modded ROM (30+ Mh/s)


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.

ETH+XVG Claymore Values
GPU-Z Monitoring

After long run, as you can see ROM works properly and stable, Until now I didn’t have any problem. Rig takes 1150-1200W from wall on dual mining mode. Before optimizations, it was taking 1250-1300W from wall.
