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.

900 mhz is the actual physical clock rate.
gddr3 transfers 2 bytes per clock and gddr5 4 bytes per clock so some write it as the higher value

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.
