Corsair RM series power supplies are optimized for silent operation click now

00:00:10.519 --> 00:00:17.240
to learn more I get asked so often lonus

00:00:15.240 --> 00:00:21.600
what RAM should I get what speed RAM should I get what capacity RAM should I

00:00:19.000 --> 00:00:24.560
get so capacity is pretty simple that's how many things you can have going at

00:00:23.000 --> 00:00:28.240
the same time so you look at your current system how much RAM you have how

00:00:26.720 --> 00:00:32.800
much your utilization is how much more would you like to be able to utilize there you go if you're not using

00:00:31.160 --> 00:00:36.440
professional applications like you know Da Vinci resolve and after effects and

00:00:34.840 --> 00:00:41.680
premere all at the same time you're probably good with anywhere from 8 to 16

00:00:38.640 --> 00:00:43.440
gigs of RAM for quite a while now when

00:00:41.680 --> 00:00:47.120
it gets into speed things get quite a bit more complicated because it's

00:00:45.000 --> 00:00:52.079
phenomenally confusing for people who don't know much about RAM speed there's

00:00:49.360 --> 00:00:59.320
frequency which will go anywhere on DDR3 from around 1333 all the way up to

00:00:55.480 --> 00:01:01.359
3,000 mahz and then there's latencies

00:00:59.320 --> 00:01:05.519
which are different okay so frequency predominantly affects the maximum

00:01:03.160 --> 00:01:09.360
bandwidth so that's how much data can be transferred to and from it at a time

00:01:07.360 --> 00:01:14.360
whereas latency predominantly affects how quickly it can respond to a request

00:01:12.159 --> 00:01:18.840
so these two things can affect performance in different applications in

00:01:16.080 --> 00:01:23.079
different ways however how much they affect things you might be surprised

00:01:21.040 --> 00:01:28.400
that it really isn't as much as you might expect so what we decided to do is

00:01:25.079 --> 00:01:30.960
we took some high performance DDR3 2.4

00:01:28.400 --> 00:01:38.360
GHz memory so that's 24 400 MHz memory and we ran it at 800 MHz okay we ran it

00:01:34.920 --> 00:01:40.840
at 1333 MHz 1600 MHz at what I'd

00:01:38.360 --> 00:01:47.320
consider to be a typical uh cast latency 9 so cl9 1,600 at cl8 so you tend to pay

00:01:45.360 --> 00:01:55.439
a little bit of a premium for a cl8 kit versus a 1600 kit 1866 and then for good

00:01:51.159 --> 00:01:57.960
measure at 2400 MHz then what we did is

00:01:55.439 --> 00:02:02.520
so we ran two games as well as cinebench just to give you some idea how it runs

00:01:59.320 --> 00:02:04.520
in games versus synthetics so here you

00:02:02.520 --> 00:02:07.600
can see the graph in front of me which basically goes okay well if you're

00:02:05.920 --> 00:02:11.800
looking at the same capacity RAM running all these different applications and

00:02:09.160 --> 00:02:15.959
different speeds you're looking at not a whole lot of difference in performance

00:02:13.400 --> 00:02:20.720
because what often happens with higher bandwidth so that it's higher frequency

00:02:17.840 --> 00:02:24.920
RAM is that it tends to sacrifice latency and then as you tighten up

00:02:23.040 --> 00:02:29.480
latencies you tend to sacrifice the maximum frequency to the point where

00:02:27.080 --> 00:02:33.360
they actually cancel each other out a lot and you end up spending more money

00:02:31.680 --> 00:02:38.120
for higher frequency RAM that might look better on paper but doesn't really

00:02:34.840 --> 00:02:40.760
deliver much in terms of a better

00:02:38.120 --> 00:02:45.720
performance you know number in the real world even our DDR 3800 which you

00:02:43.519 --> 00:02:50.760
actually can't really buy um we couldn't even find that um even our DDR 3800

00:02:48.920 --> 00:02:55.120
isn't really so much slower that it's going to make a difference so um with

00:02:53.360 --> 00:02:59.560
that said let's bring up the next graph which is the amount the number of

00:02:57.360 --> 00:03:04.920
dollars you're paying per FPS we took our gaming benchmarks and we graphed how

00:03:02.200 --> 00:03:08.239
much it's costing you per FPS because the frames per second didn't really

00:03:06.319 --> 00:03:13.560
change the performance didn't change much so spending more was basically just

00:03:10.720 --> 00:03:17.720
spending more and there are reasons why you might want better memory so uh for

00:03:16.040 --> 00:03:21.360
example if you like the aesthetic of a particular RAM kit versus another one

00:03:20.159 --> 00:03:26.200
that would be a reason to spend more money on it or if it has like cool lighting effects on it for example that

00:03:24.920 --> 00:03:30.480
might be another reason to spend more money but beyond that the way that I

00:03:28.000 --> 00:03:34.959
personally shop for money shop for money I shop for money the way I personally

00:03:32.159 --> 00:03:39.799
shop for RAM is I look for a brand that I trust so it should come with a

00:03:36.560 --> 00:03:41.599
lifetime warranty if it's worth its salt

00:03:39.799 --> 00:03:45.159
um it should be something that you know you can't find a whole lot of oh yeah

00:03:43.400 --> 00:03:48.879
this Sal all failed on me or whatever else because most of the good brands out

00:03:47.239 --> 00:03:51.959
there have pretty good reputations these days there's been a lot of consolidation

00:03:50.360 --> 00:03:56.000
and a lot of the bad RAM companies are just gone um and and that's really what

00:03:54.599 --> 00:03:59.879
I look for and you know who has a special edition RAM that like matches my

00:03:57.920 --> 00:04:06.120
motherboard really well stuff like that so there you go guys that is my take on

00:04:02.799 --> 00:04:09.200
memory yes there are situations where

00:04:06.120 --> 00:04:11.799
more memory bandwidth is needed and you

00:04:09.200 --> 00:04:17.359
can't possibly have enough most of these exist more like in servers not really in

00:04:15.200 --> 00:04:21.560
desktop environments leave a like on the video if you liked it leave a dislike if

00:04:19.000 --> 00:04:25.800
you disliked it and leave a comment if the results were not something you were
