Hello.
Me and my colleague have recently bought two identical Acer Aspire A515-54G laptops with 8GB 3200 MHz DDR4 RAM in a RAM slot. 
And while colleague's RAM is at 3200 MHz as it should, mine is showing only 2400 MHz in task manager. According to CPU-Z software we both have the same one inside, we even looked inside both laptops and there were the same RAMs installed. 
So my question is, where could be a problem? maybe I am missing some drivers. if so, which one?
Thanks for any help.
