Corsair RM series power supplies are optimized for silent operation click now
to learn more I get asked so often lonus
what RAM should I get what speed RAM should I get what capacity RAM should I
get so capacity is pretty simple that's how many things you can have going at
the same time so you look at your current system how much RAM you have how
much your utilization is how much more would you like to be able to utilize there you go if you're not using
professional applications like you know Da Vinci resolve and after effects and
premere all at the same time you're probably good with anywhere from 8 to 16
gigs of RAM for quite a while now when
it gets into speed things get quite a bit more complicated because it's
phenomenally confusing for people who don't know much about RAM speed there's
frequency which will go anywhere on DDR3 from around 1333 all the way up to
3,000 mahz and then there's latencies
which are different okay so frequency predominantly affects the maximum
bandwidth so that's how much data can be transferred to and from it at a time
whereas latency predominantly affects how quickly it can respond to a request
so these two things can affect performance in different applications in
different ways however how much they affect things you might be surprised
that it really isn't as much as you might expect so what we decided to do is
we took some high performance DDR3 2.4
GHz memory so that's 24 400 MHz memory and we ran it at 800 MHz okay we ran it
at 1333 MHz 1600 MHz at what I'd
consider to be a typical uh cast latency 9 so cl9 1,600 at cl8 so you tend to pay
a little bit of a premium for a cl8 kit versus a 1600 kit 1866 and then for good
measure at 2400 MHz then what we did is
so we ran two games as well as cinebench just to give you some idea how it runs
in games versus synthetics so here you
can see the graph in front of me which basically goes okay well if you're
looking at the same capacity RAM running all these different applications and
different speeds you're looking at not a whole lot of difference in performance
because what often happens with higher bandwidth so that it's higher frequency
RAM is that it tends to sacrifice latency and then as you tighten up
latencies you tend to sacrifice the maximum frequency to the point where
they actually cancel each other out a lot and you end up spending more money
for higher frequency RAM that might look better on paper but doesn't really
deliver much in terms of a better
performance you know number in the real world even our DDR 3800 which you
actually can't really buy um we couldn't even find that um even our DDR 3800
isn't really so much slower that it's going to make a difference so um with
that said let's bring up the next graph which is the amount the number of
dollars you're paying per FPS we took our gaming benchmarks and we graphed how
much it's costing you per FPS because the frames per second didn't really
change the performance didn't change much so spending more was basically just
spending more and there are reasons why you might want better memory so uh for
example if you like the aesthetic of a particular RAM kit versus another one
that would be a reason to spend more money on it or if it has like cool lighting effects on it for example that
might be another reason to spend more money but beyond that the way that I
personally shop for money shop for money I shop for money the way I personally
shop for RAM is I look for a brand that I trust so it should come with a
lifetime warranty if it's worth its salt
um it should be something that you know you can't find a whole lot of oh yeah
this Sal all failed on me or whatever else because most of the good brands out
there have pretty good reputations these days there's been a lot of consolidation
and a lot of the bad RAM companies are just gone um and and that's really what
I look for and you know who has a special edition RAM that like matches my
motherboard really well stuff like that so there you go guys that is my take on
memory yes there are situations where
more memory bandwidth is needed and you
can't possibly have enough most of these exist more like in servers not really in
desktop environments leave a like on the video if you liked it leave a dislike if
