Now that you mention it: what are the benefits of this? Anything else besides slightly lower wattage and temps?
It's supposed to increase hash rate - at least, that was what was observed on Windows. (And lower wattage and temps - if that's all I get I'll still be happy!) 
Topic: Underclock mem speed on HD 5970 linux? - page 2. (Read 11840 times)
I've read about Windows guys having ability to under-clock memory down to 300Mhz on the HD 5XXX cards is there a tool to do this in linux?
Aticonfig seems to be getting its minimum mem clock speeds from somewhere, GPU BIOS, how do the windows clock tools get around that?
E.g:
$ aticonfig --odgc --adapter=all
Adapter 0 - ATI Radeon HD 5900 Series
Core (MHz) Memory (MHz)
Current Clocks : 725 1000
Current Peak : 725 1000
Configurable Peak Range : [550-1000] [1000-1500]
GPU load : 99%
Adapter 1 - ATI Radeon HD 5900 Series
Core (MHz) Memory (MHz)
Current Clocks : 725 1000
Current Peak : 725 1000
Configurable Peak Range : [550-1000] [1000-1500]
GPU load : 98%
indicates the minimum mem. clock speed is 1000 MHz, configurable range [1000-1500].
Is there a --pplib-cmd that will do this perhaps? (related does someone have a list of the --pplib-cmd options?)
