Using Samsung Galaxy A14 5G Smartphone for VRSC Crypto Mining

12 Dec
2023

We put another budget-oriented smartphone to the test of crypto mining VerusCoin (VRSC) with it, this time around it is the Samsung Galaxy A14 5G. After the recent disappointment that the Samsung Galaxy A13 5G turned out to be with a 32-bit OS and unable to be used for mining we were a bit concerned about the A14 5G, but still decided to give it a go and risk it after seeing a good price deal on the Total by Verizon Samsung Galaxy A14 5G, 64GB, Black – Prepaid Smartphone (Locked) over at Amazon, was temporary down to $59 USD, though it seems to be back at $79.99 USD now. Specification wise the A14 5G did seem interesting and the nice price drop did get us to pull the trigger, but the question at hand is was it able to deliver. Read below to find out what you can expect from the Galaxy A14 5G if you plan on using it for mining VRSC…

The Samsung Galaxy A14 5G seemed a bit bulky when we got it and opened it up, it is a large smartphone with a 6.6-inch display, a device announced earlier this year. It does seem to have two versions though, one with Mediatek Dimensity 700 (the one we got) and another with Exynos 1330 chipset that will probably do a bit better than what we got as results. The Mediatek Dimensity 700 (7 nm) chipset has 8 ARM CPU cores (2x 2.2 GHz Cortex-A76 and 6x 2.0 GHz Cortex-A55) and Android 13 and the good news here is that unlike on the A13 5G model here we do have a 64-bit OS making it suitable for crypto mining. At least that is good news, but the results are not exactly as what we have expected to see from the device unfortunately.

And while the Galaxy A14 5G does work for crypto mining and provides decent hashrate mining VerusCoin it is probably not the best choice price wise and performance wise out there for sure. Initially it peaked with higher hashrate, but then stabilized at just around 3.8 MH/s and we had it running for quite some time just to be sure because of the initial fluctuating hashrate. That performance is paired with around 3.8 Watts of power usage measured at the wall, so slower and less efficient than other devices we have tested not to mention more expensive as well, so not the most suitable choice. We kind of expected to see better performance out of it, maybe the version with better specs that uses the Exynos chipset will be more interesting for crypto mining, though it is more expensive and harder to find.

Dual Mining Karlsen (KLS) and ZIL Plus Autoconversion to Bitcoin

If you are a miner that just wants to take a good profit if/while the Karlsen (KLS) craziness continues you might want to check out our quick tutorial on how to maximize your mining profit dual mining Karlsen (KLS) and Zilliqa (ZIL) with the latest Rigel miner 1.10.0 (Nvidia only) along with utilizing the Unmineable mining pool to autoconvert the mined KLS to Bitcoin (BTC) or KAS or any other of the supported crypto coins. This way you don’t have to rely on a local console Karlsen wallet or have to deal with exchanges to sell the mined coins. It is very similar to how NiceHash works, but NiceHash has not yet listed KLS, so there is no need to wait for them and you can act now. Apart from the Rigel miner, the latest GMiner (Nvidia only) has also added support for Karlsen and ZIL dual mining, and BzMiner, lolMiner and SRBMiner-Multi do support Karlsen only. We like the performance and ease of use of the Rigel miner and if you have used it for mining KAS on GPUs previously, then it is very easy to switch your config to mine Karlsen by changing the algorithm and the wallet address to a Karlsen one.

Here is command line example to get you started:
rigel -a karlsenhash+zil ^
-o [1]stratum+ssl://karlsenhash-eu.unmineable.com:4444 -u [1]BTC:WALLET_ADDRESS ^
-o [2]stratum+tcp://eu.crazypool.org:5005 -u [2]ZIL_WALLET_ADDRESS ^
-w WORKER_ID --log-file logs/miner.log --no-strict-ssl ^
--cclock 250 ^
--lock-cclock [1]1750 --lock-mclock [1]807 ^
--lock-cclock [2]1050 --mclock [2]1000

The above example is ready to be used and tweaked on RTX 3070 or similar GPUs, it uses the Unminable service with Bitcoin payouts (make sure you set your address) and Crazypool for ZIL mining (make sure you set your address), then also set your WORKER_ID as well. Just like KAS, Karlsen does not need much memory, so you can lower the clock to the minimum and keep the GPU clock higher utilizing the maximum offset your cards can sustain for reduced power usage.

You can check your mining status at:
For Unmineable: https://unmineable.com/coins/BTC/address/YOUR_BTC_WALLET_ADDRESS
For Crazypool: https://zil.crazypool.org/#/account/YOUR_ZIL_WALLET_ADDRESS

Make sure you set your mining wallet addresses in both of the above URLs in order to be able to see your own stats!

The Urlacher Makes a Full S19k Pro 115T ASIC Miner Run on 120V

8 Dec
2023

The Loki Kit by Pivotal Pleb Tech has made it easier for crypto miners to get creative and run various configurations of Bitmain S19 ASIC miners on 120V power, meaning home mining for these devices was made possible in US and other countries using this voltage. There are number of products already available using Loki and single S19 mining boards to make a good space heater for the winter such as the BitChimney Space Heater and StealthMiner, but now there is a new interesting option available as well called The Urlacher. The device is named after LuxOS engineer David Urlacher who first built this configuration, and is a triple hashboard Loki Rig with fully functional Antminer S19k pro that runs on 120V power at lower hashrate. We are working on a review of the BitChimney Space Heater already as we have ordered a unit a while ago and it has arrived, so we are already playing around with it.

The Urlacher is interesting due to the fact that it runs a regular S19k Pro miner with all of its mining boards at lower operating frequency to achieve high hashrate and high efficiency for home mining and it comes as an easier modification that can be quickly applied. No need to disassemble the whole miner to take out hashing boards or to build custom cases and it is easier to return the miner back to its original form that will hash at full speed with the regular non-120V power supply. You can get the complete miner with the modification or just the modification kit to apply to your own miner if you have one, or you can build one yourself with just a Loki Kit, a Bitmain APW3++ PSU and some other accessories to connect and make everything work. The Urlacher does 56 TH/s at 1200 Watts of power usage with 53 dB noise level, though you can play with settings to achieve different results as long as you fit in the total power capabilities of the power supply.
