Mine VertCoin (VTC) After the Switch to the Verthash Algorithm

31, Jan 2021

If you been intr crypto for longer time probably have heard about VertCoin (VTC), after all it has been available for more than 7 years already and during that time forked multiple times changing Proof of Work (PoW) mining algorithms. Well, VTC did it once more this time switching from using Lyra2REv3 to Verthash in order to bring back mining VertCoin back in the hands of GPU miners. As is it normal with forks, requiring wallet updates and new mining software things may get a bit messy initially until everyone updates to the required software and the fork just happened. This means that not all mining pools and exchanges supporting VTC have already upgraded and are ready for the fork, so make sure if you mine VTC using Verthash to do it on a compatible mining pool and keep the mined coins locally and not sending them directly to an exchange for a while more at least!

In order to be able to mine VTC with the new Verthash algorithm you need to start by downloading the latest VTC wallet (currently version 0.17.1) and running it as it will generate a Verthash Datafile on its first run. This verthash.dat file is over 1GB in size so it can take a while, but it is a requirement for the miner to start working, so you will need to wait (the dat file is required on every mining rig!).

The next thing you need is to download and configure the latest VerthashMiner, there is a Windows and Linux version available and the miner works on both Nvidia CUDA and AMD OpenCL GPUs. Have in mind that the VerthashMiner miner requires a GPU with a minimum of 2GB VRAM! In order to start mining you will need two things, a mining pool where you will point your mining hashratre (you can go for the – Suprnova Vertcoin Pool like we do in this example) and the second thing the miner needs is the verthash.dat file that the wallet will generate on its first run.

Suprnova VTC VertHash Stratum server:
– Standart Difficulty: stratum+tcp://vtc.suprnova.cc:1777
– High Difficulty: stratum+tcp://vtc.suprnova.cc:1778
– High Difficulty: stratum+tcp://vtc.suprnova.cc:1779

Example VerthashMiner command line:
VerthashMiner -o stratum+tcp://vtc.suprnova.cc:1777 -u USERNAME.WORKER-ID -p x --verthash-data verthash.dat --all-cu-devices --all-cl-devices

Make sure to replace USERNAME with the username and WORKER-ID with a worker id you have created on the pool. Then either copy the verthash.dat file from the VertCoin wallet folder to the miner folder or set the full path to the file in the miner command line.

How much VTC can you mine using the new Verthash algorithm, well that depends on what kind of video cards you have available and how many. For instance, a single power-optimized Nvidia GeForce RTX 1080 Ti video card does about 700 KH/s in terms of hashrate and that can probably get you about 1 VTC per two hours maybe (1 VTC is about $0.22 USD at the moment), though with difficulty increasing that will surely change and go down.

If you are looking for an easier alternative to get started mining Vertcoin (VTC) with the new Verthash crypto algorithm, then you might want to also check out the official Vertcoin One Click Miner that simplifies the process described above for people that are new to crypto and mining in general.

Using the Red BIOS Editor to Modify AMD Radeon Memory Timings

30, Jan 2021

Modifying the BIOS of your video card and more specifically the memory timings in order to increase the hashrate you get mining Ethereum is something that most people should do, especially when we are talking about AMD Radeon GPUs, though now a lot of miners also come with the option to optimize timings without you having to modify the BIOS. One very easy way to actually modify the video BIOS is with the help of the Red BIOS Editor (RBE) software that supports BIOS modifications of AMD Radeon GPUs with Polaris, Navi and Big Navi architecture. There are more ways to mod the BIOS for Polaris GPUs that have been available for a while, but for the newer Navi and Big Navi the RBE software is the solution, but here we are going to be modding the ADM Radeon RX 5700 / Radeon RX 5700 XT GPUs as an example. The goal is to be able to optimize the memory timings of these video cards so they can give you about 10% more hashrate for mining Ethereum (ETH), or with other word from about 50-52 MH/s you might get up to about 55-58 MH/s or even a bit more.

Before going out on a modding spree make sure you make a backup of the original video BIOS of the GPU you are about to modify, you will need this in case you mess something up and want to get back to the original settings. A good way to easy backup the original video BIOS is to use the free GPU-Z tool, though you might also find the original video BIOS in the TechPowerUp’s VGA BIOS Collection if somebody already submitted it (if not, you might want to upload it directly from GPZ-Z).

So, start up the RBE software, load the video BIOS you have saved on your computer and click on the VRAM Timings tab. You should see something similar to the image above with the memory timings RAW data and the respective frequency for which it is valid next to each video memory timing string. Since you probably don’t know what these numbers actually mean, what you need to do is just copy the timing string from a lower frequency to a higher one, then save the modified BIOS file (use a different name, do not overwrite the original backup). For RX 5700 XT you can copy the timing string from 1550 MHz and paste it over the higher frequency settings and see if the video card will be stable using these more aggressive timings on the higher frequencies, if it is not stable you can repeat the procedure with the timings from 1800 MHz and so on. You can try even lower, but the chances that it will still work with 1250 MHz are slim to note and you might need a spare GPU to reflash a working video BIOS back to the video card you are modifying.

Flashing the modified or the original video BIOS to the GPU will require the amdvbflash tool, there are different versions available and you need a special one that will work for modified video BIOSes as normally it will not allow you to flash a modded BIOS. The required flasher tools can be download below as a part of the RBE package with the ATI Flash Tool 2.93+ for the RX 5700 and RX 5700XT only, the ATI Flash Tool 3.04 for all AMD GPUs under Windows and also a Linux version should you need one. Flashing under Windows should be done with the command prompt running as Administrator and typing the following commands:

To save the original video BIOS before flashing:
amdvbflash.exe -s 0 original-bios.rom

To unlock the ROM for flashing:
amdvbflash -unlockrom 0

To flash the modified BIOS:
amdvbflash -p -f 0 biosmod.rom

* The number 0 above represents the GPU ID of the first video card, with 1 it will be the second GPU and so on for multiple cards in the same system. You can flash multiple GPUs listing their numbers separated by comas, for example 1,2,3,4,5,6 instead of just a single GPU ID number.

Do remember that after flashing a new video BIOS you need to reboot the computer in order to see the effect and be able to test the performance of the video card with the new settings. If you flash, but do not reboot, the video card will still be using the old BIOS data and nothing will change!

New GMiner 2.43 With Focus on Ethash Mining Improvements and Stability

27, Jan 2021

The latest GMiner 2.43 Nvidia and AMD GPU miner continues improving on Ethash support including compatibility with pools as well as new kernels for Nvidia. The latest update adds two new kernels for Ethash, so that now the miner support 5 kernels for Nvidia GPUs in order to ensure optimal performance depending on your GPU. Gminer automatically selects the optimal kernel by default, but you can also select specific kernel by the --oc command line parameter. The latest version also brings improved handling of device freezing as well as improved auto-tuning.

GMiner 2.43 Nvidia and AMD GPU miner changelog:
– improved compatibility with Ethash pools (shardpool.io)
– improved handling of device freezing
– improved auto-tuning
– added two kernels for Ethash, miner support 5 kernels for Nvidia GPUs, miner automatically select optimal kernel, also you can select specific kernel by --oc parameter

The GMiner miner software was originally only an Nvidia GPU miner, although some algorithms are already supported on AMD GPUs as well. Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, there is standard 2% developer fee built-in the software, though Ethash fee is 0.65% and KAWPOW fee is 1%, but there are some fees that go higher than 2% as well!
