 Okay. Today we're going to look at our RAM, the memory on our machine, without actually opening up our machine and looking at it. The free command. Very simple. You type free and it tells you how much memory you have, how much is being used, what's available. If we add dash H to that, it's going to make it human readable. You can see here it says that we have a total of 11 gigs, which really I have 12. It all depends on how it counts it. I have some swap memory there. What's being used? We have what's being free, blah, blah, blah. Okay. That kind of helps us. But I want to know how many sticks do I have in my machine and what slots are being used and what type of RAM are they. So we're going to head and try a different command. Now if we list HW, that's list hardware. It's going to list a whole bunch of information about our hardware. But we can narrow that down by running the same command dash C and typing in memory. Now it's just going to show us information about the memory on our system. And right here, it's not much more. It's telling me I have 12 gigabytes. That's not really useful, more useful than running the free command. The free command gave me more information. But it also says here, warning, output may be incomplete or inaccurate because I'm not a super user. So let's run this again as a super user. So sudo. And I'm going to type in list hardware dash capital C as case sensitive memory. I'll give it a moment here. That's a lot of information. We could look through that. But I'm just going to type in here dash short. Add that to the end of the command and I'll hit enter. And it makes it a little bit easier to read, a little more compact here. Let me shrink my screen down again. I'm going to run it again. Make sure we got all the information together. There's some more information there. So you can see the different types of memory here. But you can tell right here that we're definitely looking. We have 12 gigs of system memory. And you can see here that we have a 4 gig stick, a 2 gig stick, a 4 gig stick, a 2 gig stick. So I have 4 all together, adding up to the 12. And you can see what slots they're in. The first slot, second slot, third slot, fourth slot. And I know my system has four slots. So I know all the slots on my motherboard are being used. But I now know if I want to order some more RAM, I can definitely see what type of RAM I want to get, what megahertz we're currently running at. So I can go, okay, I can remove these 2 gigabyte ones and replace them with 8 gigs or 16 gigs or maybe 4 gigs again and substantially raise up my memory. So that's how you can find out what sticks of RAM are in your machine without opening your machine up. I hope you found this useful. Please visit filmsbychrist.com. That's Chris, okay.
