For some reason, when I am Bitcoin mining with CGMiner the "current clock" doesn't match my "max clock." Help on getting my hashrate to above 300 mh/s?

Try removing --auto-gpu flag.

Try removing --auto-gpu flag.

Hmm, that seemed to stabilize the rate at ~250 mh/s, but CAPS viewer still shows the current clocks at stock speeds and max clocks at CGMiner's parameter-set speeds.

Can you check using GPU-Z?. It makes a graph with your clocks, voltages and temperatures.

Increase worksize to 256 and intensity to 10?

It looks like you set the clocks of the wrong performance level. There are 3 performance levels (low medium high) depending on the load of the gpu. It's not smart enough to pick the highest frequency out of the 3, it just sets to perf levels and obeys the clocks of each one.

You probably changed clocks of your low or medium perf level.

Also not sure on this one, but your bat file is pretty long.. why not use a config file? It would be a lot more neater and human-readable.

Btw, your user login/password for workers shouldn't be anything that you feel uncomfortable sharing on the forums

Mine on Ozcoin are Valalvax.1 and Valalvax.2 for the worker and a for the password (anyone want to mine for me? Lol)

That monitor thing looks like a complete ripoff of CPUID, what does CGMiner say the clock is at?

I have never had success with arguments via a .bat file with CG.  I do everything through the .conf file in order to get it working properly.  I would say try editing that (you can set up failover pools as well) and try that to see if you get the desired results.
