It is recommended to begin from lower values and increase them if the miner works stably. Supported memory tweak value range is from 0 to 10 (0 means disabling timings modification, 1 is the least intense, 10 is the most intense), for example: memTweak=9,8,10 Parameter values must be separated by a comma or space (first value is for GPU0, second is for GPU1, and so on). Zero value means timings are left as is without modifications. Miner must be launched using admin/root privileges in order to change timings.ĭefault memory tweak value is 1 which means slightly improving memory timings. The following AMD ASICs are currently supported: gfx900, gfx901, gfx906, gfx907, Baffin, Ellesmere, gfx804, Hawaii, Tahiti, Pitcairn, Tonga. memTweakĬan be set to modify AMD GPU timings on the fly for Ethash algorithm. 20 means 80% power limit powerLimits=-20ġ0 means 110% power limit for 4 GPUs powerLimits= 10 10 10 10 4. You can also apply same settings for each GPU by defining only one power limit value. You can also apply same settings for each GPU by defining only one of the core and memory clock values, for example: coreClocks=+200Ĭan be used to set Nvidia cards power limits from -50 to 50. Then GPU0 will be overclocked by 200 MHz of core and 300 MHz of memory, whereas GPU1 core clock will be underclocked by 150 MHz, and its memory clock set to 3900 MHz. For example, if it is set as coreClocks=+200,-150 The values must be separated by a comma or space (first value is for GPU0, second is for GPU1, and so on). Can be used to overclock/underclock NVIDIA GPU's. Wallet=87xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2. Wallet = 0xffffffffffffffffffffffffffffffffffffffff Then the hashrate line will first display GPU3, then GPU1 and finally GPU0.Įxample of configuration file for mining Ethereum, Monero, Ubiq and PascalCoin on same 8 GPUs rig using separate devices: rigName = rig1 For example, if it is set as devices=3,1,0 The order of devices determines the order of displayed hashrate. You can see a list of available GPUs and the order in which they're in by launching nanominer with the -d command line option: nanominer -dįor example, if there are four GPUs in the system (0, 1, 2, 3) and all but the second-to-last one (indexed as 2) must be set to mine, then the devices option must be set in the following manner: devices=0,1,3 nanominer numbers the GPUs starting from zero in ascending order of their PCI addresses. If you do not want to launch the miner on all available GPUs but only on some of them, their numbers can be provided in the devices parameter separated by a comma or space. These are the graphics cards that will be used by the miner.
