The maximum RAM that can be used must be less than 2GB (e.g. GTX TITAN) or 1GB (e.g. GTX 750-TI). \r\n\r\nThanks"},"comment":{"url":"https://api.github.com/repos/fireice-uk/xmr-stak/issues/comments/351513593","html_url":"https://github.com/fireice-uk/xmr-stak/issues/369#issuecomment-351513593","issue_url":"https://api.github.com/repos/fireice-uk/xmr-stak/issues/369","id":351513593,"user":{"login":"psychocrypt","id":25899446,"avatar_url":"https://avatars0.githubusercontent.com/u/25899446?v=4","gravatar_id":"","url":"https://api.github.com/users/psychocrypt","html_url":"https://github.com/psychocrypt","followers_url":"https://api.github.com/users/psychocrypt/followers","following_url":"https://api.github.com/users/psychocrypt/following{/other_user}","gists_url":"https://api.github.com/users/psychocrypt/gists{/gist_id}","starred_url":"https://api.github.com/users/psychocrypt/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/psychocrypt/subscriptions","organizations_url":"https://api.github.com/users/psychocrypt/orgs","repos_url":"https://api.github.com/users/psychocrypt/repos","events_url":"https://api.github.com/users/psychocrypt/events{/privacy}","received_events_url":"https://api.github.com/users/psychocrypt/received_events","type":"User","site_admin":false},"created_at":"2017-12-13T20:33:14Z","updated_at":"2017-12-13T20:33:14Z","author_association":"COLLABORATOR","body":"The reason is that NVIDIA GPUS older than Pascal can not handle random memory accesses to a memory range lager than 2GiB.
