2021/08/20 挖礦小日記 : LHR顯示卡 + NICEHASH + 自行下載新版的挖礦軟體 (Gminer，Gminercuda)
NICEHASH 的 內建挖礦軟體版本 似乎太舊， 對於 某些 新版 DRIVER的 LHR顯示卡 可能無法運作，
因此 就得 自行去抓 最新版的挖礦軟體來使用。
只要把參數設定好， 即使不透過 NICEHASH MINER 也可以讓它適用於 NICEHASH挖礦。
---
其中先舉例一個 挖礦軟體 Gminer ， 裡面有 DaggerHashimoto (ETH) 與 KAWPOW(RAVACOIN)運算模式。
（ 另外，Nbminer 挖礦軟體39.1版本 已經號稱 可以 讓 LHR顯示卡，ETH挖礦可以到69%，要挖ETH 可以考慮Nbminer）
Gminer
(DaggerHashimoto (ETH) 與 KAWPOW(RAVACOIN))

https://github.com/develsoftware/GMinerRelease/releases/download/2.65/gminer_2_65_windows64.zip---
其他還有常用的挖礦軟體 ，
挖礦軟體 都含有各種不同的運算式，其中也有不錯的收益。 例如: ERGO幣的 Autolykos
例如:
NBMINER (39.1版本 已經號稱 可以 讓 LHR顯示卡，ETH挖礦可以到69%）

=== Gminer 通用的挖礦指令如下 ===
miner.exe --algo 運算幣種 --server 伺服器:PORT --user 錢包地址.自定義用戶名
pause
===
指令 小說明:
(0) 下載回來的檔案 解壓縮之後 有一個 readme.txt 檔案，裡面有參數的說明。
(1) 3BdfWtyJdbTjYjCKTaNM8wj2FPuyD5UMPV 是一組隨意的BTC挖礦地址，
請自行 替代為 你自己在 NICEHASH的 BTC挖礦地址
111111與222222 是用戶自定名稱，可以任意更改。(這個是顯示在NICEHASH的報表用的)
(挖礦地址 與 用戶名中間 相隔一個 小點 [ . ] ， 請勿消除)
(2) 若有追加 -i 99 這個指令 是讓顯示卡GPU運作在99%使用率，特意留下1%是給你平常電腦上網或處理事務用的。(若未設定此值，則默認為 100)
(假如 你有兩張 顯示卡， 就可以 下參數 -i 99 100 ，這可以讓 第一張顯示卡99% 第二張100%.)
(3) 成功挖礦之後， 過一會兒 在NICEHASH的報表裡面 應該會出現
=== NICEHASH 挖ETH幣的 .BAT指令檔 參考 ===
miner.exe --algo ethash --server daggerhashimoto.usa-west.nicehash.com:3353 --user 3BdfWtyJdbTjYjCKTaNM8wj2FPuyD5UMPV.111111 -i 99
pause
=== NICEHASH 挖KAWPOW (RAVACOIN幣)的 .BAT指令檔 參考 ===
miner.exe --algo kawpow --server kawpow.usa-west.nicehash.com:3385 --user 3BdfWtyJdbTjYjCKTaNM8wj2FPuyD5UMPV.222222 -i 99
pause
=================================
PS. 其他補充說明:
1.
(A) LHR顯示卡 挖礦時，就算不是挖ETH。
Vram頻率也不能加太多，不然也會被強制啟動算力減少機制。
(B) 目前 NBMINER 在ETH 已經可以解鎖至68% 效益 (好像是 到70% 就會觸發 減算力機制)。
(C) 不過。 其實 在某些時候 挖 ERGO(Autolykos) 或是 RAVACOIN(KAWPOW) 也有 很高的收益。
2.
ETH幣，ERGO幣 主力 是增加 VRAM頻率。
而 KAWPOW(RAVACOIN)則是需要主核頻率，VRAM不用太高
3. 降 POWER LIMIT 有 降主頻與降電壓的效果， 可避免 你的顯示卡 火力全開 而稱不過 高溫。

eth.2miners.com - main pool
eu1.ethermine.org and asia.sparkpool.com - failover pools
Miner resets mt, cclock, cvddc, mclock parameters to default values while DAG generation to avoid errors
Parameters details:
'--kernel' - allows you to choose one of several kernels, the fastest kernel is automatically selected by default.
Cores differ in performance and energy efficiency depending on the GPU model and overclocking parameters.
To set the kernel manually, pass the kernel index to the parameter.
Try to choose the best kernel for you manually by going through all the options
'--mt' - allows you to choose one of several tweaks for GPUs with GDDR5X and GDDR5 memory.
A higher value gives more performance and less stability, risk of finding invalid shares increases.
Try to check all values to determine which one suits you best.
Administrator rights required.
'--safe_dag' - allows you to choose a way to DAG generation.
In fast mode (value 1, auto for GTX GPUs) miner generates DAG as quickly as possible, DAG errors are possible at maximum overclocking.
In safe mode (value 2, auto for RTX GPUs) miner generates DAG with error control, useful for RTX cards at maximum overclocking.
'--tfan' - allows you to set a target temperature for fans.
Miner monitors temperature of GPU and actively controls the fan speed trying to hold target temperature.
'--tfan_min' and '--tfan_max' options set minimum and maximum fan speed limits.
