CGMiner - Can't underclock memory or voltage, keep settings

[purelithium]

I'm using CGMiner 2.6.5 with my 6870 and 7770 and 6550D. When I use phoenix2, I normally rely on Afterburner to boot with the system to change voltage and clocks. It works great. Now I'm trying to get CGminer set up, I can set the engine clocks fine, but no memory or voltage changes will take effect. Also when I try to set the fan autotune, and then save the config file, when I restart, the fans are just going full blast again, nowhere near the target temps.

Any ideas?

Thanks!

I'm trying to get CGMiner to work, because I'll need it for the FPGA board I'm gonna be mining on when it gets here. Phoenix can't do it, so I'm relying on CGminer.

Some info:

Win 7 HP 64Bit
Display drivers 8.98 (don't have catalyst control panel installed, I find it's just bloat.)

What else would you need?

Ok figured out the auto fan thing. Just need to start the application with the --auto-fan switch. Now I just use afterburner for clocks and voltages.
