Oh wow, I had no idea. So, Afterburner reads it as 2000 because of the 4 bytes per clock? I guess that does make sense, glad to know GPU-Z isn't holding out on me haha. Thanks a lot.
It reads my default GTX 460 clock as 900 MHZ when it is supposed to be 1800 MHZ. When I overclock to 2000 with MSI Afterburner, it reads 1000. Seems to be halving the actual clock. Anyone know why this is? Thanks.
