NBMiner developers partially bypass hashrate limitations in Nvidia LHR graphics cards – Bits Media

In the update of the NBMiner ether mining application, the developers managed to partially bypass the restrictions on ETH mining on NVidia LHR video cards. They managed to squeeze out 68% maximum hash rate.

At the end of May, Nvidia began shipping video cards, in the name of which There is an abbreviation LHR(Low Hash Rate). These cards have a limitation of mining on popular algorithms - the hashrate is reduced on average by 50%. However, now the owners of such video cards will be able to force them to work noticeably faster. NBMiner developers have not yet been completely circumvented the restrictions, but an increase in the hash. 30% - This is a step forward.

The reason for the release of a series of video accelerators of LHR was a shortage of gaming video cards on store shelves and a significant increase in their cost. Gamers got very few video cards, since the deliveries of wholesale bought large miners, even at high prices. This was facilitated by a significant growth in the cryptocurrency market, As a result, even expensive video cards paid off in just a few months.

Initially, NVIDIA tried to limit the mining hash., and miners simply installed a more old version of the drivers. However, with new batches of video cards, this trick no longer passes, Since restrictions are now preserved at the BIOS level.

Previously reported, that the video accelerators began to get cheaper after the fall of the cryptocurrency market and the Ethereum course. However, the decrease has never become significant, And after the market turning up in July, the shortage of cards returned to almost previous levels.
