ahh, I haven't seen that Generic Error before. Try using the command I listed and see what happens. And try just doing mem itself and the core itself before doing both in one call.
No dice. Same behavior. All glakkeclock does is seem to reset the lower end for peaks not actual clocks. Even if I use aticonfig to then subsequently reset the clocks to somewhere in the new lowered range, it only does the peak. The effective clock remains the same.
I've tried under 0 load and full load. Same behavior.
./glakkeclock -oscm 300 -oscg 600 -ostcs -cdi 0
Default Adapter - AMD Radeon HD 6900 Series
Core (MHz) Memory (MHz)
Current Clocks : 600 1250
Current Peak : 600 300
Configurable Peak Range : [600-840] [300-1325]
GPU load : 99%
Default Adapter - AMD Radeon HD 6900 Series
Sensor 0: Temperature - 72.50 C
Fan speed query:
Query Index: 0, Speed in percent
Result: Fan Speed: 79%
Then:
aticonfig --odsc=700,300
Gives:
Default Adapter - AMD Radeon HD 6900 Series
Core (MHz) Memory (MHz)
Current Clocks : 700 1250
Current Peak : 700 300
Configurable Peak Range : [600-840] [300-1325]

Fan speed query:

Result: Fan Speed: 75%So, it seems as though glakkeclock works for core clocks and peaks, but not for memory clocks.
It only seems to reset memory "peak" which from what I can tell does nothing. My chip runs at the same temp and mH/s. Similarly, the memory clock remains unchanged.
EDIT: If I try to set my memory clocks somewhere ABOVE the factory default minimum of 1250, that still does work. So there seems to be something in the card (?) that is only allowing glakkeclock to mess with core settings, not memory.
EDIT2: Tried backing down clocks more slowly. Guess what, glakkeclock WILL let me set memory to as low as 700, but that's it. Anything below 700 and it's the same behavior as above.
Sadly, that doesn't give me much help in terms of temp and/or speed. My chips are already running close to max core (835/840) at 75C. Changing the memory clock to 700 does save me a few deg C (down to 72.5) but no love in terms of speed. ;-(
