hi i have Corsair Vengeance LPX 64GB (4x16GB) DDR4 PC4-21300C16 2666MHz Dual/Quad Channel Kit - Black - it says its 2666mhz but according to my pc its only 1333mhz, do i need to return it or can i fix it somehow? - new to wthe world of pcs so sorry if this is a stupidly simple question

You're fine.

DDR is an acronym for 'Double Data Rate'. The system clock has a rising and falling edge when it ticks (roughly analogous to an on/off electrical signal) - DDR RAM activates on both transitions so DRR @1333 = 2666.
