	I have a NVidia GeForce 8800 GT graphicscard (with driver v.191.07), and have installed NTune v.5.05.54 in order to overclock the GPU & Memory. It is possible to tweek the memory a lot, and the GPU a little bit. Or you can tweek the GPU a lot, and the memory a little bit. Or in other words, you have a certain number of Mhz you can apply to the memory and GPU as you please. I have made some personal rules in the NTune, in order overclock my Graphicscard, when Boinc is getting loaded. And the factory settings is applied, when Boinc is getting closed. It is working in windows right now, but when Windows is starting up,the overclocking rule doesn't seem to kick in. And I have a suspicion that Boinc is beeing loaded first, and afterwards, then NTune is loaded. So NTune does'nt detect Boinc is stating up, because it is already started up. My questions are: 1.It is possible to edit, the order of, when programs is beeing loaded, when windows is starting? 2.What are the best tweeking solutions, in order to get a faster CUDA? Should I tweek the GPU or should I tweek the memory? Or a little bit of both? Btw: I have a NVIDIA CUDA driver v.2.3, but Boinc is showing "compute compability 1.1". Is Boinc detecting CUDA as being a v.1.1 instead of a v.2.3, or do I just mixing two different things up? Regards ____________

	BTW: My specs are Windows XP SP3, Pentium 4 with 3 ghz. And a NVidia GeForce 8800 GT graphicscard (with driver v.191.07), and have installed NTune v.5.05.54. ____________

	Perhaps you should ask in Number crunching. There are more of the "overclocking people" and you will also find information about the difference between driver version and compute capability.

	I also use NTune to set my clocks at boot time, no other rules. I find that it sometimes misfires and doesn't set the clocks. I monitor my clock speed now and then with either the nVidia System Monitor or something like GPU-Z (http://www.techpowerup/gpuz) to see what my clocks are currently set at. When I find my clocks aren't set correctly, I press alt-ctrl-H to bring up a list of clock profiles, then select one and click 'OK' to load it. It takes a minute or so to load and test and then it will report if it was successful or not. Then click the little 'x' in the upper right to make it go away (it's small and hard to see.) I haven't tried other overclocking tools to see if they work better at making sure the clocks are set correctly at boot time. I've seen people recommend EVGA Precision (http://www.evga.com/precision/)

	Wonder Puppy: Thanks for the reply. It seems there is a bug in NTune, when you have that simple rule, to overclock the graphiccard when windows is starting up, and it sometimes wont do that. Then I guess, it really don't matter, if I figure out, to edit the order of when NTune and Boinc to start up. I'll have a look at EVGA Precision. Thanks ____________

	Gundolf Jahn: Ok. I'll try that too.... Auf wiedersehen ____________
