If I had one of these beasts, I'd probably try to extract the maximum potential out of it (as the cooling system should keep it safe, unlike so many other Macs!). I'd probably mine Etheurum on all the GPUs and then maybe Monero on the CPUs.
I ran across this little bit of info on this helpful site,
mining.help :
"How to setup dual
mining?
Ethereum is mined just by using the memory of your
GPU, so the
GPU’s core is almost not affected by the ethereum
mining at all. This gives a possibility to utilize the
GPU core for
mining some other coins in the same time as you mine ethereum without affecting its hashrate. Of course if you would mine the dual coin at full potency, it would affect the ethereum hashrate, that’s why we will need to optimize the intensity of the dual coin, lowering it at such degree that it’s not affecting the ethereum hashrate."
I didn't know this, which confused me for while, as my
GPU stats stayed at between like 0% and 4% utilization, even when
mining fully. But, the
GPU-cores aren't really being used much, just the RAM. So, I'd probably try Claymore miner and setup BOTH Ethereum and Decred as the article indicates. I'm not sure if Claymore would also allow XMR on the CPUs? If so, that might be the one-stop solution.
I don't know what I think about all the
GPU-tuning yet. I'm assuming there is *some* danger involved? I'm not willing to risk that on my rig yet, but I'd love to squeeze out some extra MH/s at the same time. I'm trying to learn more to understand how dangerous/safe it is to do the overclocking and optimization stuff.
