[Ucci]

I need help selecting correct memory that will run in MSI x99s gaming 7 MB with I-7 5820 currently she has 16 gigs crucial ddr4 2400 32 gigs G SKILL f4-3000 rma in mail that would not run past 2400. 32 gigs is nice 64 make her more happy. less it works the more it costs me. I was looking at this F4-2400C15Q2-64GRK can not find this F4-2400C15Q2-128GRK but faster may make my life easier. so please any definate throw in click xmp and save reboot and I leave is best.
Thanks
