Use the AMD/ATI Pixel Clock Patcher For Modified BIOS GPUs

6 Oct
2019

The AMD/ATI Pixel Clock Patcher tool by ToastyX has been available for quite some time wit the main goal of modifying the AMD/ATI video driver to allow higher resolutions and refresh rates by removing the 165 MHz pixel clock limit for single-link DVI and HDMI, the 330 MHz limit for dual-link DVI, and the 400 MHz limit for VGA. A more recent feature that is useful for everyone mining with ATI/AMD GPUs that have a flashed modified BIOS is the ability of the tool to also patch the video drivers to remove the BIOS signature check. With an AMD/ATI GPU thah has a modified BIOS (optimized memory settings for better performance or specific GPU/VRAM operating frequencies preset) normally the video driver will not work properly, so you need to patch it in order for the GPUs to be able to work normally and mine.

There are other solutions available to override the BIOS signature check, but using the AMD/ATI Pixel Clock Patcher tool is by far the simplest. The current latest version 1.4.7 is compatible with Catalyst 11.9 to Adrenalin 19.9.2, though iIt can be used with future versions if it finds the limits you need. All you need to do after you install the AMD video driver is to download the tool and run “atikmdag-patcher.exe”, then just reboot and you will be ready. Since the tool modifies a couple of things if you only need to remove the BIOS signature check you can rename the executable file to “atikmdag-patcher-bios.exe” and no other things will be affected than the BIOS check. After installing new GPUs or new drivers you will need to run the patcher tool once more in order to make everything work properly again.

Ravencoin (RVN) a Few Days After the Fork to the X16Rv2 Algorithm

5 Oct
2019

A few days have already passed since the fork of Ravencoin (RVN) on October 1st that included a change in the PoW algorithm used for mining – from X16R to X16Rv2. As you can see from the network hashrate graph above from Ravencoin Statistics it is still lower than prior he spike from end of Agust/beginning of September. This means that the fork has effectively affected the usage of what seems to be ASIC miners that went operational at the end of August that resulted in more than doubling the hahsrate in just a few days of time. Another sign that there are no more ASIC miners mining and dumping coins is the fairly stable price of RVN after the fork with no selling pressure on exchanges from such miners trying to get rid go the mined coins. As a result RVN is among the most profitable coins to mine for Nvidia GPUs at the moment after the fork, even if the profit is nothing to brag about, pretty much all the rest of the altcoins are doing worse…

DERO, Another CryptoNight Project to Switch to RandomX

5 Oct
2019

The DERO project is one more crypto coin that plans to move from CryptoNight to the new RandomX algorithm most likely before the end of the year. The reason that is cided is to introduce more decentralization and participation to their platform with the move to the RandomX proof-of-work algorithm. Currently DERO can be mined using CryptoNight ASIC miners and this is something the developers of the project are trying to move away from and attract new users with the mining algorithm switch. The new RandomX algorithm should go live on the DERO testnet on October 31, 2019 and soon after that if everything works as expected we could see the main network forking to the RandomX PoW as well. Currently DERO is ranked around 500th place according to CoinMarketCap data with a market capitalization a bit below 4 million USD and has a daily trading volume of about 1/4 of the total capitalization. Some good crypto exchanges to trade DERO coins include Stex, Crex, Citex and TOKOK.

RandomX is a proof-of-work (PoW) algorithm that is optimized for general-purpose CPUs. RandomX uses random code execution (hence the name) together with several memory-hard techniques to minimize the efficiency advantage of specialized hardware. More information about the RandomX algorithm from the official GitHub repository including a benchmark to test performance on CPU mining. Do note that RandomX dos manage to perform better on processors with higher number of cores and threads available and apparently is doing best so far on the latest AMD Ryzen series of CPUs. GPU miners are also available, however performance wise they are similar to what hashrate a lower-end dual core processor can provide, so they are not the best choice for the new RandomX algorithm for the moment.
