About speed: for example, 4xx cards will get about 15% speedup. 390 cards will get less.
PS. Please don't PM me about getting pre-release version - I don't have any private versions/builds.
Is there any update for cpu?
someone injected claymore v8 with a trojan and probably was trying to steal information
probably included something to open a backdoor port on the computer which would let them in to control the miners (change mining wallet address), possibly take control and lock you out so have to pay a ransom to get control back or both and also to see if there was anything on the hard drive.
