00:00:02.399 --> 00:00:09.080
okay so why does memory come with more than one stick in a kit what are these

00:00:07.200 --> 00:00:12.679
channels everyone's always talking about find out everything you need to know

00:00:10.519 --> 00:00:16.720
about RAM channels as fast as possible by watching this video When shopping for

00:00:15.240 --> 00:00:21.160
computer memory there's all kinds of specs to pay attention to including the

00:00:18.520 --> 00:00:25.000
frequency the timings the voltage and how many sticks actually come in the kit

00:00:23.080 --> 00:00:28.880
and how many channels they're rated for you can usually tell by the little

00:00:26.880 --> 00:00:32.520
number on the memory itself or on the box showing you how many pieces are

00:00:31.000 --> 00:00:36.559
intended to be in the kit that's normally how many channels it's intended

00:00:34.399 --> 00:00:39.520
to be operated in before you buy your memory you need to check your

00:00:37.719 --> 00:00:43.520
motherboard or computer system to find out how many channels it supports the

00:00:41.559 --> 00:00:47.160
easiest way to do this is the manual or the manufacturer website but failing

00:00:45.640 --> 00:00:51.800
that you can check the labels on the motherboard itself or you can usually

00:00:49.760 --> 00:00:57.320
tell by checking for colorcoded memory slots so they are normally coded with

00:00:54.160 --> 00:00:59.440
all the same colors for how many sticks

00:00:57.320 --> 00:01:03.680
you're supposed to populate at a time with one kit this particular board is a

00:01:01.680 --> 00:01:07.520
quad Channel board which means it has four slots that are one color and four

00:01:06.000 --> 00:01:11.320
slots that are another color that doesn't mean that you have to run quad

00:01:09.360 --> 00:01:15.880
Channel kits in it it just means that that's what will yield the best

00:01:12.840 --> 00:01:17.479
performance now A Memory kit is just a

00:01:15.880 --> 00:01:21.759
bunch of individual memory sticks that are validated to work with each other

00:01:19.680 --> 00:01:26.159
flawlessly in however many Channel operation it's rated for so in this case

00:01:24.040 --> 00:01:30.720
a quad Channel kit could be reduced to a triple Channel kit or a dual Channel kit

00:01:28.759 --> 00:01:33.560
just by taking memory sticks away because all those sticks are still

00:01:31.960 --> 00:01:38.200
validated to work with each other normally that is to say that you could

00:01:35.840 --> 00:01:41.680
normally take a quad Channel kit install all four sticks in a dual Channel

00:01:39.799 --> 00:01:45.799
motherboard and it would operate in dual Channel with your full capacity full

00:01:43.200 --> 00:01:50.200
performance and everything normally I said normally an awful lot of

00:01:48.600 --> 00:01:53.880
times in that last shot there there's a reason for that this is a quad Channel

00:01:52.320 --> 00:01:58.680
kit could I install it in a dual Channel board sure yes would it work probably

00:01:56.840 --> 00:02:02.360
there are primary timings which the manufacturer tells you so so if it

00:02:00.360 --> 00:02:06.039
doesn't detect correctly in your dual Channel board you could easily change

00:02:03.960 --> 00:02:09.319
them around but there are actually more timings in fact some boards will give

00:02:07.640 --> 00:02:13.200
you access to secondary and even tertiary timings on the memory that can

00:02:11.319 --> 00:02:17.400
be optimized to work with a particular platform if the manufacturer sells you a

00:02:15.319 --> 00:02:24.440
quad Channel kit they're expecting you to use it in an LGA 2011 board not an

00:02:20.480 --> 00:02:26.680
1156 1155 or am3 board if you want to

00:02:24.440 --> 00:02:30.200
run in dual Channel generally speaking buy a dual Channel kit if you want to

00:02:28.239 --> 00:02:34.160
run in Quad Channel don't buy two dual Channel kits cuz they might work but

00:02:32.680 --> 00:02:37.280
you're better off to buy a quad Channel kit cuz sometimes those optimizations

00:02:36.160 --> 00:02:43.080
even though there's nothing wrong with the memory and nothing wrong with the board can cause stability issues and

00:02:40.959 --> 00:02:46.640
they can be difficult to override and to diagnose now I'm not going to try and

00:02:45.000 --> 00:02:49.720
convince you that if you mix and match your memory your system's going to

00:02:48.519 --> 00:02:55.800
explode and it's not going to work at all cuz there's a good chance it actually will however if you're

00:02:53.319 --> 00:02:59.800
populating your memory with unmatched sticks there is a chance that they won't

00:02:57.760 --> 00:03:03.400
operate in dual Channel or triple Channel or quad Channel or whatever your

00:03:01.400 --> 00:03:07.400
motherboard is rated for which can negatively impact your performance in

00:03:05.280 --> 00:03:11.760
fact in this board right here I've got a triple Channel kit installed in a dual

00:03:09.799 --> 00:03:17.920
Channel motherboard which can on some boards actually reduce the entire memory

00:03:14.640 --> 00:03:19.959
bank to single Channel performance so if

00:03:17.920 --> 00:03:23.840
you need the extra RAM capacity more than you need the bandwidth there can

00:03:21.640 --> 00:03:27.840
still be a benefit to doing this but in most cases it's not ideal you're better

00:03:25.720 --> 00:03:31.959
off to take one stick out or add another matching stick another example would be

00:03:30.239 --> 00:03:37.080
a quad Channel motherboard with a single stick installed this example gives you

00:03:34.680 --> 00:03:41.120
one qu of the total bandwidth that that CPU might need or that that motherboard

00:03:39.080 --> 00:03:44.200
is capable of delivering so it's just not an optimal

00:03:45.040 --> 00:03:51.080
