the original inspiration for this video came when alex craftily turned the
0:05
surface laptop he'd just finished writing the review for into his daily
0:08
driver and realized that our model unfortunately only has eight gigs of RAM
0:14
with no way to upgrade it but does that matter
0:18
well the commonly held wisdom for years has been that unless you're some kind of
0:22
power user eight gigs ought to be enough for everyone well
0:27
hold on with Windows 10 and chrome devouring memory like kobayashi at a hot
0:31
dog eating contest we've been regularly seeing memory usage over 20 gigs just
0:37
from web browsing on our writing workstations
0:40
so we started an investigation ek
0:44
waterblox's mlc phoenix lineup is designed around quick disconnect
0:47
couplings and brings a modular approach to connecting and expanding your water

1:03
so our testing rig has a core i7 7700k
1:06
a gtx 1080 ti and a one terabyte SATA
1:10
SSD then we equipped it with 4
1:13
8 16 or 32 gigabytes of RAM
1:18
at each stage we tracked page file usage with performance monitor then opened up
1:23
tasks until we noticed activity once you
1:26
reach the threshold where the system starts to swap data out of RAM and onto
1:30
the boot drive you might not necessarily see the system slow to a crawl or
1:34
anything like that but you could see a dip in performance or responsiveness if
1:39
a tab or an application that you go to access has already been paged to your
1:44
SSD or your hard drive so first up is chrome we'll be looking both at how many
1:50
chrome tabs are open when Windows starts using the page file and how many are
1:54
open when chrome eventually becomes unusable bear in mind that not all tabs
1:59
behave identically i've seen some use two gigs of RAM on their own but
2:03
we chose a mix of web pages that we feel should be representative of typical
2:07
browsing behavior with 4 gigs of RAM we actually hit the
2:12
page file with just 5 tabs open and then
2:15
after 13 chrome crashed alrighty then with 8 gigs we got to a
2:21
respectable 25 taps before any of them got swapped out and managed 40 before
2:26
the situation went totally south with 16 gigs of RAM we reached a fairly
2:32
unreasonable 80 tabs open before page filing and then chrome finally crashed
2:37
at around 180 then with 32 gigs of RAM
2:40
we got all the way to 165 tabs before paging
2:45
and frankly we didn't feel like going through the actually kind of laborious
2:49
process of opening and loading 350 to 400 web pages in chrome tabs just
2:56
to see the program fail i mean if you want that many tabs you're kind
3:00
of doing it wrong and this is coming from me
3:03
so let's move then into gaming if all you're doing is playing a game
3:08
i think you might actually be surprised by how little RAM you actually need
3:13
deus ex mankind divided for example which recommends 12 gigs of RAM
3:18
didn't suffer too badly even with only a single 4 gig stick although with that
3:23
said rise of the tomb raider had some serious issues that were only sorted out
3:28
by bumping up to 8 gigs of RAM after that though performance didn't
3:32
change for either of them when we jumped to 16 or 32 gigs
3:37
so okay then eight gigs for gamers actually maybe not i mean what if
3:43
you don't painstakingly close down all of your running applications every time
3:47
you launch steam for those folks we popped open our 10
3:51
tab test suite and an instance of discord to see if eight gigs could
3:55
handle it and surprisingly enough there was no
4:00
difference at all with the exception of rise of the tomb raider that game seems
4:04
to really love its RAM so then depending
4:07
on the game you probably won't need 16 gigs of RAM to play it
4:12
but it won't give you a ton of breathing room for the future and you might need
4:15
to limit your background tasks for the best experience so then what does anyone
4:20
need more than eight gigs of RAM for
4:24
well i would argue that any kind of workstation is going to want
4:28
at least 16 and you might be surprised to find out that even more is pretty
4:34
common for those kinds of systems alex actually has a number of excel
4:39
documents from his engineering days that believe it or not will not even open on
4:43
a computer with eight gigs of RAM and has had some simulations of fluid flow
4:48
or suspension movement that crash out even with 16 gigs of RAM
4:53
video editing can also be very demanding
4:56
but this is heavily dependent on your workload if you're cutting together
5:00
short to medium length 1080p videos 16 gigs should be plenty
5:05
but the sky is the limit here if you use tools like after effects you can expect
5:10
needing 16 to be an absolute minimum and
5:13
as the complexity of your project increases so does your RAM requirements
5:18
our latest season of scrapyard wars for example because of how darn much footage
5:23
was in the timeline immediately crashes with anything less
5:27
than 64 gigs of RAM although for more
5:31
information about how much RAM you need for video editing specifically you can
5:35
check out our video here where we tested it with up to 128 now it should be noted
5:40
that all of what i'm saying concerns system memory and not video memory which
5:46
is used for loading in 3d objects and textures for your graphics card's use
5:52
this is very important for games and also professional applications
5:56
but is probably a discussion for a different video
6:00
one i can almost guarantee will end with well it depends one interesting side
6:06
note before we wrap up is that as we moved up from four gigs of RAM our
6:10
system boot times actually got slower it was only at most a second more but this
6:15
is cool if you're aware of a Windows feature called super fetch it actually
6:19
makes sense super fetch tries to intelligently preload some programs into
6:25
RAM so that they'll launch faster when you need them so the idea is that if you
6:30
run out and buy excess memory it can still be used for something which
6:35
doesn't mean though that we're saying to do that as you might have noticed RAM
6:39
prices are out of control right now so
6:42
our recommendation for general users and gamers is eight gigs if you're looking
6:48
to scrape by and be ready to upgrade later and 16 gigs if
6:53
you want to be comfortable for a while as for the workstation users out there
6:58
well uh it depends
7:02
and you know what else it depends on that doesn't depend on that at all
7:05
forget it Corsair's new light loop fans
7:08
these things look freaking incredible
7:12
they have dual RGB lighting loops with
7:15
16 independent RGB leds in every fan
7:19
that are split between two separate loops allowing for nearly endless
7:22
customization the included Corsair lighting node pro enables dynamic
7:27
lighting effects with other Corsair link supported devices and they've got
7:31
complete pwm control so they can be controlled anywhere from 600 RPM all the
7:36
way up to 1500 RPM depending on whether you want them to be quieter or cool more
7:41
efficiently so check them out over at the link in
7:44
the video description because come on baby it's RGB you know you love it
7:50
so thanks for watching guys if this video sucked you know what to do but if it was awesome get subscribed hit that
7:54
like button or check out the link to where to buy the stuff we featured in the video description also down there is
7:59
our merch store which has cool shirts like this one and our community forum
