Shader/Core Straps ?

[wolf2009]

Ocing a gts250. why does the clock move in increments of some mhz ? and why is the value in GPU-Z and Rivatuner's Monitoring software different ?

Since G80 nV has used stepped core frequencies that go in 27MHz or multiples/dividents of 27MHz. The reason why GPU-Z and Rivatuner Hardware Monitor don't agree usually is because GPU-Z reads the frequency the video driver requests thus ignoring the hardwired freq steps, but Rivatuner detects the actual frequency by sniffing it from the chip. You can ignore GPU-Z's frequency "readings".
