Welcome back to the come ta plus 2 to +0-1001 module to this is less than 3.4 ram configurations. We're gonna talk about the single duel in Triple Channel Ram. I'm your structure Bill Price.
Okay, so let's look at our lesson objectives. We're gonna talk about Siegel Channel Ram do Chan Aram, and finally talk about Triple Chan around. So let's go and get started.
Okay, So first, let's have our Ram Channel overview If you're building or upgrading your system, your systems RAM is one of the most important components. People generally believe that RAM helps the processor work faster. In reality, random access memory ram
basically throttles the system for achieving its maximum potential performance.
This is because the processors always going fast to the ram, which results in the processor having to wait initially for RAM to deliver the data. During this wait time, the CPU sits idle.
Waste in power in time, a bottleneck, more or less. Advances in technology have attempted to address this speed issue by moving on to duel and triple channel techniques to increase speed.
The ram in the system is controlled by a circuit that is referred to as the memory controller. Older systems. This was the North Bridge ship. If you remember that from previous lessons, newer systems this is in the processor has taking over that responsibility.
The ram and the memory controller are connected through a series of wires and better known as the Memory Bus.
These wires they're further divided into three groups. Control data and an address.
The control wires are responsible for sending the commands to the memory modules, which contained the information about what kind of operation is being performed by the system.
The data wires will carry the data that is being read from memory to the memory controller or being written from the memory controller to the memory.
Now the memory controller is possible. Responsible for setting the memory speeds are the clock rates of the memory module at the minute Memory Controller states that the maximum clock rate that it's a sports is going to be 1333 megahertz.
Even if you install a 24 24 megahertz memory module in the system,
it wouldn't be able to utilize all of it. It'll be able to use utilize the potential of just 13. 33 megahertz on Lee. So this is like under clocking your ram.
And if you see him from a graphic again, if we put a 24 100 megahertz ram chip into the system and if you only got a 13 33 megahertz bus, your CPU is going to be just waiting.
So single Channel Ram
Ah, single module ram operates on a single 64 bit data channel, which means that it could pass data down to a single pipe that is only 64 bits on dhe total. With
so again, just that single channel 64 bits That's the pipe or the highway or the throughput. The lane with that you're using is a 64 bit channel. And as we
talked about previously as technology advances, we need thio increase. This we have higher process is doing more things, so we need to ah, faster way to channel this data from the memory mountains to the controller. So that brings us to double Channel ram
and dual channel RAM memory system. The system makes use of to memory channels. Now we have got to 64 bit channels available to the memory, the double the data traces passed on the memory bus now have 100 20 a bit channel.
So as you can see here, we've doubled that with now Ah, 120 a bit Channel
form or throughput and Maur pass from the memory to the memory controller. And that brings us to
Triple Channel RAM in triple channel memory. The system makes use of three memory channels. Now we have three times 64 bit channels available to the memory. We've tripled the data paths on the middle on the memory bus and now we have 192 bit channel.
So there you have it. As faras technology is advancing, we get Maur um paths from the memory to the memory controller. Now, if we lay these out and if you look at the board you wanted probably want to determine how do I know if I have
Triple Channel Ram or do Channel Ram,
two or three member mountains must be installed in matching banks. That's one characteristics of the duel and triple Channel round. This is a quick way. Identified the type of channel supported by the motherboard.
So in some of the older systems. If you look on the far left a single channel ram, you have just the multiple regular
ram modules that you put your Ram Ian one stick, comeon start or two sticks. If you put one stick in, say, for instance, of just a gigabyte ram, you got a giga some memory to deal with. If you got to, you got to gigs on. This is just
standard basic, uh, older memory that you have put into the system.
Now, as you come into Dumb Double Channel Ram or the dual channel RAM, you'll see that you have the matching banks that you must be installed and you could see that these banks are separated. There is a bank at the top of the bank. At the bottom, you would have to install these and matching banks, and also your memory modules
are sold in these matching banks called matching sets,
so you would have to install them in matching sets on of equal ram in both sets. To get stick in the first round, bank into gig in the second bank, consult your your mother board manufacturers, far as it's a requirements of memory in being the matching Rams sets that you could get for that motherboard.
And if you look at the final graphic here on the right,
this is Triple Channel Ram, and you could see there's three matching banks right there. So you would buy your memory in three matching sets.
So very, very good lesson. We talked about the Ram Channel overview. Then we talked about the single channel Ram, the dual channel RAM and the triple ramp. So that is all for our lesson today, and we will see you in the next lesson.
