Overclocking With Igp

Hello all

If I bought a motherboard with integrated graphics, would overclocking the CPU automatically do the same with the graphics? or is it independant depending on bios etc?

if it does then thats bad for overclocking and i'll get discreet. i'm hardly a gamer due to time and so need bare minimum graphics power.

Should remain independent afaik. uATX often doesn't have a block on the PCI-E lane so a discrete graphics card has to overclocked but not integrated.
