First off, you’re not going to get rich from mining on your old unused BeagleBone black and you’ll arguably only lose money, but for about 10W of power, you might be able to mine some low difficulty altcoins that are cpu or gpu only. I am currently mining Galactrum on mine using CPUminer-multi.
Thanks to its wide array of miners, you can use cpuminer-multi to mine a lot of altcoins, so lets get into compiling it.
Its 2019 and your Raspberry Pi is sitting in the corner. You haven’t used it much since your last project and you are ready to do more with it. Why not mine a CPU only or low difficulty coin? Sure you won’t get rich, but you’ll have some crypto to trade around and learn about compiling miners and how to use exchanges and how to use mining pools. The Pi also uses a very small amount of power.
Magi coin uses a POW/POS system but with a bit of a twist. As they put it “MAGI concentrates on global energy savings when maintaining its blockchain system. MAGI aims at worldwide mining based on, for example, mobile devices. MAGI’s PoW with difficulty dependent mining rewards applies a limit to the total network hashrate, where huge amount of computational power for mining is no longer necessary”
This makes it the perfect target for mining with that old Raspberry Pi you just have lying around.
Is replacing your stock cooler with the popular Hyper 212 EVO worth it?
When I built my computer I had narrowed down my CPU choice between two processors, an AMD FX series or the i7-4790k. I ended up going with the i7-4790k as it was a better performer and AMD processors are notorious for running hot and I didn’t want to deal with trying to keep high temps under wraps. When I installed my new i7-4790k I used both the stock cooler and the stock thermal paste.
My computer booted up, and after I updated my drivers, began bench-marking. I was expecting medium-high temps as I am aware of Intel’s stock cooler performance issues and the heat hyper-threading can give off, however I saw temps as high as 80-90°C. After some research, I headed over to Amazon and purchased two things, the Hyper 212 EVO and some Arctic Silver thermal paste.
When my shipment arrived I removed the stock fan to find that there was very little thermal paste on the CPU or cooler due to the stock paste drying up. My extremely high temps were likely a symptom of inadequate cooler to CPU contact and an inefficient cooler.
After cleaning the old paste off the CPU chip, I put a pea sized dot of the Arctic Silver thermal paste onto the CPU and installed the Hyper 212 EVO. Installing the new cooler was a bit more difficult than the stock cooler, but it’s still easy enough that the average user can install it. After securing the cooler and the backplate, I rebooted the PC, this time enabling the OC genie that came with my motherboard. I re-ran 3Dmark and saw about a 5-10% increase overall in performance and the Max temp was 60-70°C, a temp that is well in range for an overclocked i7-4790k. The Arctic Silver thermal paste and the Hyper 212 Evo had lowered my max temps by about 20°C and my ambient temps by about 5-15°C. That’s quite a gain for such a low cost air cooler.
The Hyper 212 EVO paired with the Arctic Silver thermal paste solved my overheating issues with my i7-4790k and I fully recommend the popular air cooler, which you can buy on Amazon by clicking their picture below. I personally prefer air coolers over water coolers because air can provide sufficient cooling without the worry of a defect dripping water all over your newly built PC.
