I haven't tried the BIOS mods. I could be wrong, but I'm sceptical that they'd make any worthwhile difference. What is worthwhile though, especially if you have one of the 'OC' series (pre-overclocked) cards, is to adjust the GPU clock speed in Wattman. I found that at around -15% to -20%, there was minimal reduction in hash rate but a reduction in power of nearly 50W per card.
A single RX 480 should produce a little over £2 per day presently, using NiceHash. I find it better to look at the mBTC rate though otherwise you have two variables (the rate that NiceHash are paying and the BTC/GBP price). NiceHash profitability is quite low presently, though it does appear to be rising again. A couple of weeks ago I was getting about 1.6 mBTC per card, now it's more like 1.1 mBTC. A couple of the tech forum members I've been discussing mining with have been experimenting with mining Ethereum/Zcash directly and claim they're seeing slightly higher earnings compared with the current NiceHash rates. I plan to experiment doing the same in the coming weeks so I'll report my findings.
This is what one of my 2 card RX 480 rigs is presently earning using NiceHash:
One thing to note when using NiceHash is that payouts only occur when you reach certain thresholds (see
here) and there is a small fee for each payout. So if you're mining on various GPUs/devices, especially if they're lower hash-rate devices, it's probably better to use the same Bitcoin payout address on each device, that way it'll be one more frequent payout rather than lots of smaller payouts.
