Novice troubleshooting questions should first consult the sidebar, notably the many guides and the EtherMining WIKI link first. Same as #2 for asking general "What Should I Mine?" See sidebar for links, including profitability calculators. Please retitle.Īsking about general ROI / "Is x Worth It?" posts will be removed unless it hasn't been asked in a while, generally a week or two, at the discretion of moderators. Posts with titles such as "Mining Advice" or "ASUS GTX1070?" will be removed. If you’re struggling to find overclock settings that don’t trigger LHR and the LHR setting value keeps dropping, try lowering the locked core clock ( -lock-cclock) until it stops working.⚒️ Simple Questions thread ⚒️ Sub's WIKI ⚒️ /r/MiningRigPics ⚒️īe specific with your title.Don’t change the overclocking settings too much while the miner is running, especially be careful of changes that can cause the hashrate to drop quickly, such as lowering the memory overclock or significantly lowering the power limit (all while mining) - this can trick the miner.You can increase the hashrate averaging window and smooth out fluctuations by using the -N option, for example -N 180 will tell the miner to report the average hashrate over 3 minutes instead of 1 minute (which is the default). Hashrate will fluctuate even more in dual mining mode. During this process, the reported hashrate will fluctuate and mostly stay on the down side because each LHR block will cause the miner to pause for 20 seconds to unlock LHR, so you may need to wait until Tirex finds stable settings. The miner will try to achieve a reasonable hash rate using the provided settings, and if that is not possible, it will start aiming for a lower level.It is important not to manually set intensity values as this may interfere with the unlocking algorithm.If you want to disable autotuning and keep the LHR setting value constant, start the miner with -lhr-autotune-mode disabled. To return the old behavior, use -lhr-autotune-mode full. Since version 0.25.15, the LHR autotuner works in down mode by default, i.e. It also reduced the value of the setting if it lowered LHR too often. Previously, when T-Rex tried to unlock LHR cards, it defaulted to “Auto LHR Setting” where it would automatically increase the LHR setting if the graphics card was stable and did not reach LHR at the current setting value.99 - use this value for your GDDR6X video cards if you find it difficult to make overclocking settings for LHR.91 is a good starting point for graphics cards with non-Hynix GDDR6 memory.80 - graphics cards with GDDR6 Hynix memory, they do not work well with unlocker, so you may need to try even lower settings.0 - disabled (use for cards other than LHR, or for those that are not affected by LHR with the overclock you use).To enable the LHR unlocker, you need to explicitly tell the miner which GPUs are LHR-limited at your current settings.Mining ERGO, unlike ETH, is not aimed at LHR, so its effect is not so pronounced. The HiveOS equivalent would be "lhr-tune": "0,0,77.5,0" ERGO lhr-tune 0,0,77.5,0 - this will tell the miner that the third video card is LHR and that it should start with a setting value of 77.5, while the rest of the cards are non-LHR. It can also be set per GPU separately, e.g. 78 is the recommended starting value for most LHR cards.74 is the recommended initial value for most LHR cards in low power mode (see -lhr-low-power).0 - disabled (used for cards other than LHR).LHR mode is enabled by default for LHR maps, however, if you want to override automatic LHR map detection, you can do so by specifying the -lhr-tune option, which takes values from -1 to 100:.T-Rex has a partial LHR unlock feature for 30xx GPUs mining ethash (~78% of full hashrate). So add this page to your browser bookmarks. This section will be updated as more people provide feedback on which settings are considered stable. Important: If your GPU is LHR limited on ERGO in single mode, no matter what overclock you set, this dual mode is not for you as the miner will constantly hit LHR locks. Some numbers are approximate (this is done with the -lhr-tune 30 command, which is the default): ETH+ERGOĮRGO is known to be affected by LHR and for most GPUs one should find overclocking settings that don’t run LHR when mining ERGO solo (single mode) and then use the same settings for ETH+ERGO dual mode. Different coins have different memory requirements, so below you will find a list of available combinations along with memory requirements.
