Same RAM different capacity?

[OBielegend]

I'm looking to upgrade my RAM.

 

I currently have Corsair Vengeance LPX 8GB DDR4 3000mhz C15 (2 x 4GB).

 

I can buy a kit of 16Gb (2 x 8GB) for less than a 8GB (2 x 4GB) .

(2 x 8GB) - https://www.amazon.de/Corsair-Vengeance-3000MHz-Performance-Arbeitsspeicher/dp/B013GZ5PD2/ref=sr_1_7?ie=UTF8&qid=1552666043&sr=8-7&keywords=ddr4%2B3000mhz&th=1

(2 x 4GB) - https://www.amazon.de/Corsair-Vengeance-3000MHz-Performance-Arbeitsspeicher/dp/B0123ZBS6O/ref=sr_1_9?ie=UTF8&qid=1552666043&sr=8-9&keywords=ddr4%2B3000mhz&th=1

 

Will the difference in capacity be an issue?

Note - I'm on the Ryzen platform.

no no issue, both sets will run in dual channel just fine
