No. In fact, performance may actually decrease due to the way modern memory controllers work. You see, unless you happen to come across very old, very slow 8 GB sticks of DDR4 RAM rated no higher than 2400, virtually all 8 GB sticks are only single-ranked. And benchmarks have proven that only one rank of memory per channel actually performs almost as sluggishly as running a PC with only one stick of RAM (and thus forcing single-channel mode). That is because of a memory controller phenomenon called interleaving. You'd actually need those two 8 GB sticks to be dual-ranked (and practically nobody manufactures 4Gb ICs for dual-ranked 8 GB DIMMs any more).I have 2x16 gb ddr4 4000cl19 and currently run them at 4400cl17. If I change to 2x8gb 4800 or 5000, do I get more fps? Im gaming at 1440p and I dont see any fps increament when oc my ram to 4400 from 4000.
