Hello Here's my problem. I bought a new laptop from sony which came with a downclocked GT330m. I thought I could just install rivatuner and overclock it. no big deal. When I launch rivatuner however I get this message: driver signing enforcement must be deactivated...disable now and reboot? which doesn't work. I googled it and found some commands to disable it but it doesn't work. I am about to try some registry changes but wanted to know if you have some other solution? Never have I encountered this problem and I often install beta drivers from nvidia. :O
Its because you are running x64. RT does have a signed driver though, so can use it without messing around.
