Optimal number of threads when mining

As a general rule of thumb: Cryptonight, the PoW hash Monero uses, needs a 2 MB scratchpad in fast memory, so you will want to have all your mining threads able to keep their scratchpad in cache. So ...

Which type of hardware is the most efficient for mining Monero?

In terms of power efficiency, the reigning champ was the Nvidia 750Ti. That GPU will get you 250H/s and use about 30-40W power. For efficiency, that puts it around 6H/s/W. With the optimized ARM64 ...

Which type of hardware is the most efficient for mining Monero?

There are no ASICS yet, and GPUs are about 2-4x faster than CPUs. Monero's PoW algorithm has a large memory requirement that would make it difficult to use an ASIC and less advantageous to use a GPU ...

Is it better to mine with a CPU or GPU

The most profitable consumer-grade hardware that I know of is the GTX 750 Ti (an nVidia GPU). This is on a Hashrate per Energy Used basis, since the marginal cost of mining is the energy spent. It ...

How long do I need to mine until I see some coins in my wallet?

The reason you haven't seen a payout is because most pools have a threshold level below which they won't bother sending xmr to you. Your share per tick is: 160 H/s / 50.53e^6 H/s, with a network ...

Optimal number of threads when mining

I played around a bit with using different numbers of threads on different machines, and my best results came from just using half the number of cores on that machine. Here's part of my script to ...

After major coin issuance, what must the minimum XMR price be to incentivize network security?

This is kind of a subjective question. Currently the block reward is ~ 10.4 XMR per block or 5.2 XMR per minute. When the tail emission kicks in, the block reward will be 0.6 XMR per block (assuming 2 ...

How can i specify in mining to only use 75% of my CPU power?

Typically if you have an AES-NI capable processor you will find the "sweet spot" at 1/2 the number of cores you have, so you won't ever be mining to 100% anyway. Right now we don't have a mechanism to ...
