Tekkit Classic and Dedicated Card doesn't work

[fullje]

Hi! I've got MSI GP60 with nVidia 740m ( dedicated card ). In my laptop, my power button have two colours. Blue when i use intel graphics card, and the red when i use dedicated card. When i turn on my minecraft without any modpacks my power button lights on red. But when i turn on technic pac -> Technic Classic my power button lights on blue, even if i click on the technic pack and select ( Turn on with dedicated card ). And i think that thereby i've got small amount of FPS. On normal minecraft ( without tekkit ) i've got about 60-70 FPS, on tekkit about 25-38. And i think it isn't caused by big amount of mods. My question is: How to Turn the tekkit with the dedicated card. In the nVidia options i have got set 'Turn Tekkit with dedicated card' But i think it doesn't work. Some help:)?

Aside from using the nvidia control panel to force the javaw.exe process to use graphics card specific settings it is almost impossible to guess.
