How many Chrome tabs can you open with 2TB RAM?

two terabytes of RAM how on earth do you pack two terabytes of RAM onto a single system I mean it sounds crazy to say it out loud and it is a little crazy I mean unless you're looking at exotic quad or eight CPU socket designs even a server grade motherboard like this one from gigabyte typically tops out in the neighborhood of sixteen memory slots so step one then is we are going to need some very special memory a single stick of this ramp has more capacity than your entire system one of these is 128 gigabytes of memory and naturally to hit 2 terabytes as advertised in the video title we are going to need a lot of them SK Hynix is also promoting their new gold s 31 SSD every component of the gold s 31 SATA 3 SSD was produced built and designed by SK Hynix to meet their quality and performance standards we're going to be using this as our boot drive during our testing and I'm going to have a link to where you guys can learn more in the video description [Music] I've got to ground myself here I'm pretty sure SK Hynix isn't sending me more of these if I zap them so get ready for a technical deep dive guys traditional registered server dims operate in parallel such that effectively each of the individual memory chips on the module is wired directly to the memory controller that's built into the CPU so that's where all the traces that you see running between your memory slots and your CPU socket come into play now there are two ways that you can increase the capacity of a memory module you can add more chips by putting them on both sides or by double stacking them like we see here or you can actually engineer the chips themselves with more data areas or ranks a dual rank memory module might have exactly the same number of visible chips soldered onto it but it's effectively like smashing two single ranked modules into a single slot and a quad rank module is like stuffing four modules into a single slot which is pretty cool if you need more capacity but it causes a small problem the memory controller on a given CPU has a limited number of ranks that it can be wired into directly before performance starts to drop off or it reaches a hard limit so you might run into cases in the server world where even though a motherboard has you know let's say 16 slots you could populate all of them with dual rank modules or only half of them with quad rank modules and then running at a reduced speed there's not much point in doubling your memory density if you cut away half of your expansion slots and some speed right like that's classic one step forward two steps back so we're getting around that problem today using what's called load reduced or lrdimms and there is a lot of engineering packed into these they run at a blistering 29 33 megahertz so that is the rated speed of our AMD epic 64 core processor and they have both a ninth chip in each one of these rows for ECC or error correction and an extra memory buffer chip that allows the processors memory controller to operate in serial mode this serial operation causes a quad ranked dim to load the memory controller like a dual rank dim or an eighth rank dim to operate like a quad now it comes with a performance penalty but if you I'm not talking to you Siri what what what even is this what are you talking about now it comes with a performance penalty but if your workload requires a ton of memory taking a small latency hit is a lot better than not having enough RAM at all set a good example I love these sockets where you just screw the cooler right into the socket just need a boot SSD so all the memory volatile or otherwise in our system is actually made by SK Hynix in Korea they're one of only a handful of actual memory manufacturers in the world and they've been making SSDs for years but it's only recently that they branched out of just system builders and enterprise users into retail so let's get Windows 10 loaded up on this peppy moment of truth time server boards lack a lot of the creature comforts of consumer boards so we're just gonna short a couple pins turn it on like I'm standing here eagerly waiting but I'm not actually expecting it to do anything anytime soon every time you boot up a motherboard with a new hardware configuration it needs to go through a process called memory training and the more RAM you have the longer it takes so this could take like 10 minutes to turn on the first time it may have taken long enough for a wardrobe change ltte store.com what we're up to million ninety seven thousand one hundred and fifty two megabytes of memory running at twenty nine thirty three million transfers per second 64 cores of processor goodness and actually got a cool tip from gigabyte that apparently is you pop in here and ignore all of this warning stuff free you can actually overclock your memory on this platform so it turns out the maximum limit for installed memory for Windows 10 Pro happens to be boom you guessed it exactly 2 terabytes so this is a bog-standard Windows 10 install with 0% memory usage I could probably even open up Chrome and it would still be 0% before we proceed with our entire test though I do plan to find out just how many tabs we can handle I want to have a look at what performance looks like with our configuration it's worth noting that our 64 core processor actually doesn't have SMT enabled so it's only running 64 threads it's a bit of an idiosyncrasy of this board right now and I haven't spent any time figuring out boom 52.4 for seconds so we're not looking at some kind of you know crippling performance difference or anything like that so we got to figure out a good way to do this so Brandon hit me with some websites YouTube alright B&H photo video just got some Neopets in there you know linkedin what are you talking about Brandon we're hearing on LinkedIn she's sure yeah hey there is this is a terrible LinkedIn profile alright that seems like seems like he's sticking her ass Newgrounds oh I love it and we'll head over to the mkbhd store this is my favorite 10 million subscriber commemorative merch right here chrome is actually using two and a half gigs of RAM right now doing functionally nothing so it's a hog still it just doesn't make a dent it doesn't even register its flatlined so let's do it let's open all 20 tabs in a new window yes I'm sure all right we jumped from five to five point eight now I want to find out if cycling through them actually increases it so we're gonna ctrl tab over through all these tabs and see if it jumps it's gonna slow us down quite a bit in terms of how many tabs we can open per minute here if we have to do that and it looks like we don't hey that's great news so now this just becomes an exercise in how fast can I click this is super dumb I want a piece of paper you know I'm gonna start tallying how many tabs I'm opening any paper update for you guys at 200 chrome tabs we are now at 10 gigs of RAM and 1% usage 600 tabs 700 tabs 900 tabs 1000 tabs 5% this is interesting Neopets seems to be our heaviest website first you take my youth then you take my CPU cycles we're up to 69% CPU usage well I think we're gonna run at a CPU before we run out of memory here guys we are over one stick of memory use now 132 gigs Chrome at least admits that it's using over 100 gigs of RAM now power usage very high 5,000 tabs here we go please grant hey we're at 10% RAM usage now so that's sick but what's interesting is that in spite of us having resources available to us the system is getting slower and slower and slower to the point where even when this ad managed to load in I couldn't help but notice it was running at a super crazy low resolution look at this here here's a perfect example it just froze while it was playing back that's what it looks like opening a hundred now when we already have 5000 open in the background was like opening up the first 500 when we did it now this is interesting I was going to rearrange the tabs to shoot the thumbnail and we got a spike in CPU usage and not sure memory actually changed but check this out a bunch of these tabs that were already open before our reloading now so it seems like interacting with the window actually gets it to refresh but that doesn't change our RAM usage and since that's what we're after I guess that's still ok Brad dad Brandon we might have hit our limit brightness but I want to get the thumbnail if I have to open them all against you hit the damn Bell it's gonna suck 6,000 we're at the point now we're doing almost anything in Chrome on the system I'm trying to combine a tab I accidentally dragged out of a browser window back into it and it just it's not responsive enough to do it but oh hey well it did it okay so we got that I mean gimps managing to open up that's cool we are just shy of 200 gigs of memory usage now and that's just from rearranging all the tabs we were at closer to like 185 weren't we this is so weird check this out this up here says Amazon but mkbhd is also selected and this is an Apple website it's uh strictly speaking we may not be at the limit but from a practical standpoint I think we've reached the limit oh no I think I just did the wavy thing where everything minimizes the system is completely unusable at this point look at them all go all right click three four five six seven twenty five twenty there it is just shy of 30 seconds just to right-click so we only managed to use about a tenth of our RAM half of our CPU but we seem to have reached architectural limits of the software itself whether it's Chrome or Windows and 6000 tabs is well beyond what is actually usable in Google Chrome I hope you guys enjoyed coming along with us on the ride massive shout out to SK Hynix for sponsoring this video sending over 2 terabytes of memory even though we didn't manage to use it all this time and of course providing their goal that's 31 SSD for us to boot off of it's available in 250 gig 500 gig and 1 terabyte capacities it comes with a five-year warranty and if you're looking for a high performance SATA SSD you guys can check it out it is at the link in the video description so thanks for watching guys hope you had as much fun as we did with this insanity and we will see you in the next video if you enjoy more server type content like this we actually built a craziness a little while ago you can check out that video down below

Spoiler alert, IT"S UNDER 9000!!!!

But pretty close!
