thanks for clarification! some people think, it's AMD-CPU dependend and HyperTransport must be fast enough (like HT3 with K10 CPUs) to address memory.

hmm? i have to check this! now i've made one adaption in my xorg.conf (in device-section --> Option RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1"). this should drive the GPU to "maximal performance". i have to reboot/reload X and nvidia-modules in the evenening. At the moment i'm getting:
------------------
nvidia-settings -c :0.0 -q GPUPerfModes -t
perf=0, nvclock=550, memclock=350

nvidia-settings -c :0.0 -q GPUCurrentPerfMode -t
1
nvidia-settings -c :0.0 -q GPUCurrentPerfLevel -t
0
nvidia-settings -c :0.0 -q GPUCurrentClockFreqs -t
550,350
------------------

hmm - i'm not a specialist, but the Geforce 9400GT shoult have 1350 MHz unified shader clock! here i recnognize a value of 350 (but maybe this is something else?)

thanks for driving me in the right direction
