Does RAM speed REALLY matter?

Now that we have RAM modules capable of up to 4266MHz, we need to find out… does high speed RAM ACTUALLY make a difference?

    MHz of RAM dont matter at all. RGB RAM = + 10% performance!

    Faster system ram is for overclocking your CPU ,depending on game it can help ,RTS games with intensive Artificial Inteligence ,where you micromanage large armies benefits more , but faster graphics card GDDR5 ram is a totally different story ,it makes your games a lot more faster than even overclocking your CPU. you can earn 10% -20% or more performance. There are some benchmarks of Witcher 3 at 4k ,with faster memory that shows this.

    you forgot to say that for lower cas latency you need higher clocked ram running a lower clock.. am i wrong?

    Why is it that almost every single video on youtube has these features.
    1. annoying person
    2. talking forever before getting to the point
    3. taking 60 seconds to say something you could have said in 10
    4. irrelevant information

    This should have been a 2 minute video.

    If you try to run higher than 2400 on Ryzen, you will get Memory Management Blue Screens at least like every other day…

    i got 3200mhz ram..then read that the 7600K only uses 2133mhz..ffs slow my ram down 🙁

    Thankfully my b350 does 3000mhz just fine on my corsair ram 🙂
    perfect for my r5 1600

    So, basically I should just go with the two sticks of 8Gb Corsair Vengeance that I've been considering.

    I hope you claimed that Burberry raincoat as a business expense!

    EXACTLY what i was looking for. Trying to help my friend decide between 3200 ram and 2666 with the 1700X and seeing a 1.54% improvement is what we needed to hear. Thanks so much!


    Can you create a similar interpretation for developers, if not on particular but on a more general scale???

    It. Matters but in special cases and as you go high the latency is effected
