00:00:00.040 --> 00:00:06.839
one of the most mystifying questions that has endured for years in the PC

00:00:04.160 --> 00:00:10.960
Building Community is how much RAM speed and timings actually matter and seeing

00:00:09.240 --> 00:00:16.160
as many of you are making the transition from ddr4 to ddr5 we figured it' be a

00:00:13.799 --> 00:00:20.720
good time for an updated video that can help answer this question currently

00:00:18.279 --> 00:00:25.720
faster RAM tends to show benefits when you're using application where the CPU

00:00:23.240 --> 00:00:30.320
isn't the component bottlenecking you in other words if it's something where the

00:00:27.480 --> 00:00:35.719
CPU's cores are working really hard it doesn't matter as much how fast data is

00:00:33.040 --> 00:00:40.200
moving from the RAM to the CPU as the CPU is already too busy working on all

00:00:38.079 --> 00:00:46.079
that data this means that in general terms tasks like video and image editing

00:00:43.360 --> 00:00:50.680
Ai and file compression won't be affected too much by RAM speeds on

00:00:48.600 --> 00:00:55.199
Modern systems although exceptions for specific applications do exist however

00:00:53.160 --> 00:01:00.840
RAM speeds can make a difference for gamers depending on what exactly you're

00:00:57.879 --> 00:01:05.000
playing to be clear the GPU is still Far and Away the biggest Hardware Factor

00:01:02.920 --> 00:01:09.439
affecting gaming performance and it's also true that having a sufficient

00:01:07.080 --> 00:01:14.799
amount of RAM is more important than having faster RAM but all things being

00:01:12.159 --> 00:01:21.000
equal how fast is fast enough when it comes to ddr5 gaming A good rule of

00:01:17.439 --> 00:01:23.360
thumb is that ddr5 6000 tends to be a

00:01:21.000 --> 00:01:28.520
good sweet spot between those cheap 4,800 speed kits and those pricey

00:01:25.960 --> 00:01:32.079
modules rated at 8,000 or even higher and if you're curious about what those

00:01:30.079 --> 00:01:36.840
numbers even mean this is a module's rated speed in megga transfers per

00:01:34.600 --> 00:01:41.240
second multiplying that number by eight gives you the number of megabytes of

00:01:38.479 --> 00:01:45.600
data transferred per second but why 6,000 well we'll tell you where we got

00:01:44.040 --> 00:01:49.560
that number from right after we think I fixed it for sponsoring this video say

00:01:47.399 --> 00:01:55.200
goodbye to those unreliable Dollar Store tools from now until May 31st you can

save 20% on all of iFixit toolkits their

00:01:55.200 --> 00:02:02.159
comprehensive Protech toolkit has everything from a variety of tweezers a

00:01:59.200 --> 00:02:06.880
makeo drive kit with 64 bits and their funny sounding but very useful spudger

00:02:04.640 --> 00:02:10.759
tool or check out the repair business tool kit their repair shop in a bag so

00:02:09.720 --> 00:02:18.040
head on over to the link in the description check out if fix's toolkits and save 20% until May 31st AMD has

00:02:16.519 --> 00:02:24.200
actually come out and straight up said that ddr5 6000 is a sweet spot for the

00:02:20.879 --> 00:02:26.120
ryzen 7000 and 8000 series processors

00:02:24.200 --> 00:02:30.959
Intel though has not made a similar statement but 6000 is about right for

00:02:28.800 --> 00:02:35.280
their processors as as well for both manufacturers getting too far above

00:02:33.239 --> 00:02:39.440
6,000 megga transfers can make it difficult for a memory controller to

00:02:37.239 --> 00:02:44.040
keep up with all that incoming data for AMD specifically their current lineup of

00:02:41.599 --> 00:02:48.120
ryzen CPUs uses a linkage called Infinity fabric that connects the

00:02:46.040 --> 00:02:53.040
various chiplets within the processor AMD has recommended leaving the infinity

00:02:50.480 --> 00:02:56.800
fabric speed on auto to get the best performance for whatever you have your

00:02:54.519 --> 00:03:01.319
RAM speed set to but turning your RAM speed up too high can cause the clock on

00:02:59.440 --> 00:03:05.959
the infin inity fabric to automatically drop which can offset the performance

00:03:03.360 --> 00:03:10.959
gains from the faster RAM and also keep in mind that chips with 3D vcash also do

00:03:08.480 --> 00:03:15.400
not benefit as much from higher ddr5 speeds as that extra cash memory helps

00:03:13.519 --> 00:03:19.799
make up for RAM that's slower than otherwise might be ideal that being said

00:03:17.720 --> 00:03:24.120
that doesn't mean you can't try to use RAM above 6,000 megga transfers but at

00:03:22.280 --> 00:03:28.920
that point you're getting into the realm of possible instability or diminishing

00:03:26.840 --> 00:03:33.400
returns depending on exactly how much you're paying for your RAM especially if

00:03:31.080 --> 00:03:38.599
you start pushing into the 7,000 range keep in mind too that 6000 is already

00:03:36.120 --> 00:03:43.959
past the officially supported Max speeds for current gen CPUs from both companies

00:03:41.959 --> 00:03:47.920
and as it is with overclocking other computer parts some of your luck will

00:03:45.959 --> 00:03:51.720
come down to the Silicon Lottery this basically means that some chips come off

00:03:49.799 --> 00:03:56.200
the assembly line with more overclocking potential than others some folks have

00:03:53.680 --> 00:04:00.959
had good luck with speeds above 7,000 but that doesn't necessarily mean that

00:03:58.280 --> 00:04:06.280
you will and of course not all games will benefit from faster RAM as a very

00:04:03.920 --> 00:04:10.360
general rule it tends to matter more when you have games that run at lower

00:04:07.959 --> 00:04:14.280
resolutions and higher frame rates think esport titles where users want as many

00:04:12.480 --> 00:04:20.519
frames as they can get at the possible expense of visual quality but what about

00:04:17.440 --> 00:04:22.720
latency you know memory timings lower

00:04:20.519 --> 00:04:26.720
numbers are obviously better if you can afford them but it isn't likely that

00:04:24.840 --> 00:04:30.840
you'll see a big benefit from spending a lot more money just to get the lowest

00:04:28.600 --> 00:04:34.759
timings possible so unless you have some kind of very specific need for the

00:04:32.560 --> 00:04:39.000
faster memory we definitely recommend getting the higher capacity if you're on

00:04:37.080 --> 00:04:42.919
a budget especially if you're planning to run other applications while you're

00:04:41.039 --> 00:04:46.840
gaming maybe you're streaming maybe you're keeping an eye on a video or

00:04:44.520 --> 00:04:52.080
maybe you're just some kind of demon who can play at FPS while sitting through a

00:04:49.320 --> 00:04:55.440
