NBMiner 發布的新更新似乎部分繞過了NVIDIA 的 GeForce RTX 30 LHR系列挖礦限制。在更新日誌中NBMiner報告說用戶可以在其LHR顯示卡上解鎖高達70%的最大挖礦速度,這可能會促使礦工購買LHR系列,從而導致再次供應短缺。
NVIDIA GeForce RTX 30 LHR系列的推出是為了限制整個遊戲顯示卡產品線的挖礦算力。這樣做是因為礦工們由於其強大的挖掘能力而吞噬了GeForce RTX 30系列 GPU的全部庫存。這導致遊戲顯示卡嚴重缺貨,從而導致零售領域的價格上漲。直到現在我們才看到市場復甦,遊戲顯示卡價格恢復正常。
但是帶有最新更新的NBMiner可能會改變這一點。NVIDIA的GeForce RTX 30 LHR系列採用完全不同的Ampere SKU系列。您可以在下面看到NBMiner v39.0的更新日誌:
39.0(2021-08-15)
feature: ethash New LHR mode for ETH mining on NVIDIA RTX 30 series LHR GPUs, supports Windows & Linux, able to get ~70% of maximum unlocked hashrate.
This mode can be tuned by argument -lhr, only works for ethash right now.
-lhr default to 0, meaning even if -lhr is not set, LHR mode with -lhr 68 will be applied to LHR GPUs if certain GPUs are detected.
Tune LHR mode by setting -lhr <value>, a specific value will tell miner try to reach value percent of maximum unlocker hashrate, e.g. -lhr 68 will expect to get 68% of hashrate for same model non-LHR GPU.
Higher -lhr value will results in higher hashrate, but has higher possibility to run into lock state, which will leads to much less hashrate.
A good start tuning value is 68, which has been tested to be stable on most rig configurations.
-lhr value can be set for each GPU by using comma separeted list, -lhr 65,68,0,-1, where -1 means turn off LHR mode.
目前LHR顯示卡提供的總挖礦速度為其預期的一半,但在新更新中您可以將此值設置為68%(按照開發人員的建議)。這僅適用於乙太坊(ethash 算法),但現在很有可能其他挖掘算法也可能採用它。平均70%左右雖然不是完美的,但也沒有50%的挖礦限制那麼糟糕。即使這種收益也會促使礦工再次購買遊戲 (LHR) GPU,並可能影響未來 LHR GPU 的可用性和價格。
