Does RAM speed REALLY matter?

  • Published: 20 April 2017
  • Now that we have RAM modules capable of up to 4266MHz, we need to find out... does high speed RAM ACTUALLY make a difference?

        Fortnite is a memory performance game, I really seen a difference going from 2133 to 2666 to 3200

              But... What happens when you spring for 3200mhz RAM that is even on the QVL and won't go to 3200.... 🤨

                        When I jumped from DDR3-1866 to 2400MHz I felt the system was snappier and faster in startup and in opening applications. The CL for 2400 was very aggressive at 9, which was more expensive than CL10 but difficult to find, anyway my RAM is Corsair Dominator Premium series.

                          Thats why i am still using 2666 while everyone else is trying to troubleshoot their 4300.

                                i hate it when "Tech" channels do this... the Frequency isn't actually speed... its Data transfer size really.
                                The Speed is from Tighter timings... honestly buy lowest CL and increase the frequency that will yield better results.
                                if you only increase frequency from 2133mhz to 4266mhz this would only shift the FSB:Dram ratio and basically increase the size amount of data through put but also increase the latency.
                                Now if you'd downclock the 4266mhz module to let say as example CL10-10-10 4000mhz you'd yield about 37ns response time and yet have bigger bandwidth this in turn would be better overall system performance because the cpu and gpu can process the data much faster from each other because the ram would be faster instead of having a 4266mhz @ 80ns. or 2133mhz @ 40ns

                                                        @David Mitchell as long as the board and cpu supports it only.

                                                        @Thiago Mendes I see.
                                                        but when I check ASUS website, the board only support base speed of up to 2666MHz ...


                                                        did I understand something wrong here?

I had 10-30% better in game performance when setting faster sticks to 3200 MHz then setting everything to 2666 MHz. If you can get faster RAM, I advise you do. I'm not easy on my PC and the performance difference was huge!

I know my RX 570 8gb is plentiful to runn 100+ fps on med for most games. I'm tempted to upgrade my ram to 3200mhz but I'm on the fence if it's worth it or not.

                                                          2666 is bottlenecking like crazy, 3200 is the lowest for me. If anyone is saying they see no difference, they probably just let the pc sit idle or play minesweeper at best.
