Have You Updated to Claymore Dual Miner 15.0 for Ethash Mining

10, Nov 2019

The latest version of Claymore’s Dual Ethereum AMD+NVIDIA GPU Miner v15.0 has been released a while ago, but there seem to be quite a lot of people mining Ethash-based coins using older versions of the miner on their GPUs. If you are one of these people that update their GPU mining rigs less often and do not touch them while they are working just fine without always updating to the latest mining software, you should plan to upgrade to the latest version 15 of the miner. The reason for that is quite simple, Ethereum (ETH) is reaching DAG Epoch 299 very soon (currently at 296) and older versions of the miner will simply stop working as prior version 15 of the Claymore Dual Miner DAG Epoch support is until 299. Some of you might have actually experienced issues with that if trying to mine Ethereum Classic (ETC) as it is a bit ahead of ETH in terms of DAG Epochs and already past the 299 mark (currently at 305), so for ETC version 15 is a must. This problem is specific for the Claymore miner as there are other Ethash miners that do not have the limitation out there, but this is still the most popular GPU miner for Ethash, so make sure you re up to date to avoid any possible downtime when ETH reaches Epoch 299. Other forks of Ethereum are way behind on their DAG Epochs, so they do not have a possible problem with older versions for now, though you should still update just to be on the safe side. It is especially important to be up to date with version 15 if you are using services such as NiceHash where you might be mining a lot of different coins with your Ethash hashrate, including ETC.

Optimizing AMD GPU VRAM Performance With the AMD Memory Tweak XL Tool

7, Oct 2019

Modifying the BIOS of an AMD video card with different operating frequencies or better memory timings and then flashing it on the GPU has been the primary choice of crypto miners for a while. Due to the introduction of the BIOS signature check in the video driver by AMD some time ago this also required users to patch the video drivers in order to continue using them with more recent video drivers. Earlier this year the AMD Memory Tweak Tool has been released and meanwhile it has evolved into a quite the useful alternative to BIOS modding. The latest AMD Memory Tweak XL makes it really easy to modify memory timings, memory straps or PowerPlay Table “on the fly” as well as access the ADL Overdrive and MMIO Register Control on newer GDDR5/HBM-memory based AMD video cards. This means that you can change the settings and apply them directly and test how they will affect performance and stability, changes are not permanent and as soon as there is some issue you can easily revert back to the default values.

The AMD Memory Tweak XL tool requires that you have .NET Framework 3.5 installed in order to function, if it is not available on your system it will automatically detect and offer to download it for you… though you might experience various issues when trying to install the framework on some mining rigs. Also your Windows needs to be in Test Mode in order for the tool to properly function, it will offer to get you into Test Mode if you are currently not and there is a button to easily get you back to regular operation. The AMD Memory Tweak XL is originally intended for more advanced users, though you should be able to quickly get up to speed on what and how to modify to get better performance. You can look at what other users have reported as settings that give better performance on their specific mining GPUs and try them and experiment on what your AMD GPUs are capable of. Even if you already have an modified video BIOS you can still play with the memory straps for example in order to squeeze some extra performance to test even better settings before applying them with a new BIOS modification.

Claymore’s Dual Ethereum AMD+NVIDIA GPU Miner v15.0

28, Aug 2019

As both Ethereum (ETH) and Ethereum Classic (ETC) are getting close to the Epoch 299 (the currently supported one by the previous versions Claymore GPU miners) Claymore has released an updated version of his dual GPU miner for Ethash algorithm with the new version 15.0 supporting up to Epoch 384. If you don’t know the Epoch 384 will mark the limit for mining for the GPUs with 4GB video memory, meaning that they will not be able to mine Ethereum (ETH) anymore as well as any other fork that reaches that epoch. Currently Ethereum Classic is at Epoch #289 or slightly ahead of Ethereum which is at Epoch #281, so make sure you update your Claymore miner before reaching #299 if you are mining any of these Ethereum variants (or any other Ethash-based alternatives although they are probably far behind in terms of Epochs). Reaching Epoch #384 is probably going to happen near the end of 2020 and the next 6GB Epoch is probably going to be reached sometime around beginning of 2024 for Ethereum… that is unless we switch to PoS before that time, but even if ETH switches to Proof of Stake other Ethash coins probably won’t.

Apart from the update regarding new DAG Epoch support for the latest version 15.0 of Claymore’s Dual AMD and Nvidia Ethereum GPU miner, there is also added support for Navi cards (ETH-only mode), now the miner also sets environment variables automatically (required for 4GB AMD cards) as well as some minor bug fixes and improvements. So make sure that you update your miner for Ethash if mining ETH or ETC at the moment on your GPU mining rigs, before the software stops functioning properly at Epoch #299, you have a bit more time before that happens, but do not wait for the last minute.
