So there is currently no way to do it with cgminer? Sad

And my card is not OCed, can I raise the speed without OCing it, or is that the only way?

In my experience that's not a cgminer problem (using -I d for sha256d like Bitcoin works fine), but a scrypt problem: sha256d barely uses the RAM of your graphic card but scrypt uses it heavily so it probably interferes more with other programs using the graphic card.

So it is something cgminer has to start optimizing especiialy for scrypt?[...]

I'm not sure there's anything cgminer can do about it. You probably can tune cgminer to use less graphic RAM at the expense of mining performance though (use less threads and/or larger gaps, see SCRYPT-README) but I'm not sure how much it could help.

Anyway scrypt was chosen because it supposedly would be slower on GPUs than CPUs even if it has been proven wrong it's no surprise it will cause problems on GPUs that sha256d doesn't cause...
