The manufacturer of video cards NVIDIA is preparing to release a new series of equipment codenamed LHR (Lite Hash Rate), in which it will re-introduce restrictions on the extraction of cryptocurrencies, Videocardz.com reports.
The new models will share a common name with the existing ones, but will technically be different. The changes will affect the NVIDIA RTX 30 line, new and old video cards in which, with some exceptions, such as the RTX 3090, will be released in a modified version.
The GPU GA10X-XX2, in addition to the mining limiter, will support the ResizableBAR technology, which opens the central processor access to the entire video memory stack of the graphics accelerator, which, according to the company, will increase performance in some games by almost 12%.
NVIDIA announced plans to halve the computing power when mining cryptocurrencies on its graphics cards in February this year. She successfully coped with this task, until in March she herself posted a driver to open access to remove the restrictions. The company said it was done by accident.
In the future, NVIDIA does not intend to release a GPU without a ResizableBAR and a mining limiter, so all new cards will need a different driver. It was presented on Thursday with a note of the relevant changes. So, the new version of the RTX 3060 will receive a PCI device ID 2504, which will make it incompatible with the old driver. It is expected that the delivery of modified video cards will start in mid-May.
Earlier, experts stated that it is almost impossible to change the driver and remove the mining limiter without the help of the company. This is borne out by the fact that miners were unable to bypass protection prior to the release of internal software by NVIDIA itself.
“It’s not just the driver. There is a protective relationship between the driver, the RTX 3060 chip and the BIOS firmware to prevent the hashrate limiter from being removed, ”explained Brian Del, RTX Product Line Promotion Manager.
