Due the Bitcoin downtrend, mining profits have really dwindled over the last couple of months. For those of us who don't have the benefit of cheap/free electricity, it's becoming really important to maximise the efficiency of our rigs. So I thought I'd share a 3 things that I've tried lately to squeeze as much kh/w as possible in the hope that others may also have some good ideas. • Re-flashed the BIOS on each of my cards. This lifted my hashrate by about 5%, whilst reducing power consumption by a whopping 15% and lowering my an speeds. Also seemed to give a marginal improvement on reject rates and WU. Amazing how bad the factory BIOS can be.

• Stopped overclocking. For a while I focused purely on hashrate, whilst largely overlooking WU & reject rates. I came to the realization that those few extra kh/s weren't worth having because of lower WU and higher reject rates. Also, if you're metering power consumption at the wall, you soon realize the extra wattage that overclocking takes is not insignificant. I also found that my rigs were much less stable when I pushed them to the limit.

Admittedly this may not seem strictly relevant to efficiency, but if you have a decent internet connection it should ultimately result in more VTC/w. The big reason I say this is that my node runs at 100%+ efficiency, and I get about 0.9% DOA, which compares very favourably to the pool average of around ~15%, and my previous average of around 4% on an external node. This is the only way that I know of to actually use the inefficiencies of other miners to improve your own! Also, I'm not paying any pool/node fees, unless my node goes down. On my 'to do' list: • Cooling.

Spring has sprung, and my garage is no longer the cool spot that it used to be. Temps and fan speeds and creeping up. I need to get some extraction in there next week. • Shop around for the cheapest power deal. I just moved house, so it's something I'd probably have been doing anyway. I'd love to hear anyone else's tips/techniques fro getting the most out of their rigs.

Done this before, it was expensive though. I used a water cooling loop in my system running over all the cards and had it running through a heat exchanger in my giant hot water tank, between the cards they maintained a decent temperature in the water at all times and it also hauled the temps down on the cards.

Of course if you turned on the heating and heated the hot water normally from the boiler the water going to the cards would be extremely hot and cause issues. Quick release valves and a giant bucket of water I can switch the system over to was on standby.

It's getting really hot in my basement now, especially after I added rigs with 290 cards (single fan). When it was cold, I used to suck cold air in from the basement window and keep the door to basement open which would heat up first floor to 67F. After it got warm outside, I switched the direction of rigs and sucking hot air out as well as installed portable A/C, but this is not working great.

I need a powerful fan not a crappy one I have now, hopefully that will make things better. Can't find any good fans. Sad to hear you had to switch off. On the other hand, at least you have a good awareness of the costs involved, and at what point your profit has totally evaporated. I'm guessing quite a few hobby miners have a blind spot when it comes to efficiency/profitability, which is what motivated me to post. In answer to your question, I use R9 290s, and I posted the thread that I lifted the modified bios from in an earlier reply. The bios is by someone called 'thestilt'.

I think he's pretty prolific, so you may be able to find a similarly optimised bios for your cards. Try some Google magic?
