Hello all! I had 2 spare 8gb modules of 3200mhz ram and decided to put them in my friend's pc. He has an i5 7600k on an Asus Strix z270e motherboard. I installed the ram and enabled xmp but his pc actually performed worse in Time spy, Firestrike and Cinebench r20. Once I swapped back to his old 2400mhz modules his performance went back to normal. Any ideas why this may be happening? Thanks in advance!
