No, not unless the ram modules that came with your computer are defective or having errors. Both your ram and "new" Corsair ram will be running at the same frequency.
It's only if you overclock your system will this make any difference. For example, the ram that came with your computer may not be able to run at higher frequencies or receive a higher voltages without errors or damage.
Higher quality ram will enable you to push your hardware further. Don't waste your money.
