DDR5 having a standardised dedicated interface for peripheral controllers (e.g. for RGB) is going to be such a lifesaver for security. The existing implementations often just expose the SPD SMBus (I2C) to unprivileged users, which opens up all sorts of holes and makes a total mess of the platform security model.
I don't think an exposed SPD-only SMBus is a huge deal for security as the only thing you'd be able to do is reprogram modules (if they're not write-protected), potentially bricking the system. I would be much more concerned if _other_ devices are also exposed.
@@eDoc2020 exploits like rowhammer do exist. Having access to it could allow making sidechannel attacks more likely to succeed, or even just possible where they weren't before.
@@ANDSENS Perhaps that is a risk, and I definitely think unprivileged access to a hardware bus is bad. However I still wonder why manufacturers don't just write-protect the EEPROM as an additional precaution. Actually I just looked up the 24C02 datasheet and only the top half gets write protected, so that's one reason. Still, they could use a different chip if they wanted to.
@@eDoc2020 The issue is that the SMBus for the SPD is often shared with other devices, particularly on laptops. Also, many drivers expose *all* SMBus interfaces, not just the one used for SPD, and often other interfaces too (Asus asmmap driver is a good example)
@@reversedon8698 Me also. Haven't upgraded since Feb of 2011. Now, do I wait a bit longer, upgrade to DDR5, and all that comes with it, or upgrade to the best of this the DDR4 Gen?
@@frontbattles8090 Please tell me what amazing scientific discoveries you've made that have allowed you to understand and consequently determine the presence of consciousness in organisms/objects? We don't even know what consciousness is my dude. You can't just rule it out by sheer appeal to familiarity, that's a fallacy.
Like I did with DDR4 and DDR3 before it....I'll wait a year or so before making the jump to the new spec. It always coincides with a fun upgrade anyways, so good to know it'll be all solid by then.
I really love Linus' analogy on the port systems. DDR4: M4 Benelli (M1014 for US Marines), Saiga 12, USAS-12, SPAS-12, SPAS-15 and AA12 DDR5: DP-12 and Neostead 2000
"DDR5 desktop platforms are right around the corner..." So like, in about three years when we can actually get our hands on it for a respectable price? lol
Even at a reasonable price for a new module of DDR5 and buying a new motherboard for DDR5, I don't think it's worth it. It's new. There are kinks that need to be worked out and will be. They'll see some modules give off too much heat and redesign them. In another year or so after release itll be better probably
You will be lucky to get them for respectable prices within 3 years, I say min 5 years later you will be able to buy second hands onces at respectable prices.
Dance Dance Revolution 5 looks different than I imagined, good for them to completely remove the gameplay and convert it to a stick of RAM instead, simply phenomenal.
You guys did an absolutely amazing job on this. The animations and the way you explained some very complex concepts was incredible. Keep up the great work!
DRAM is a capacitor matrix and the recover you mentioned is the memory refresh. Capacitors loose charge with time and tiny ones have very little charge so a refresh circuit must read and rewrite the memory content all the time - and that becomes critical if a part of the matrix has been used for a time (reading) and a refresh mush be done right after that.
I'm unsure on what I should do, I got some DDR3 at 16GB of RAM, should I go ahead and upgrade to the to-be cheaper DDR4, or the more futureproof DDR5? I mostly use my PC for work related to modelling & texturing, also videogames, none of that video editing or programming.
I’m personally gonna wait a while before i upgrade, the PC component scene right now is super overpriced so I’ll wait till everything goes down and ddr5 gets better
@MaestroEpicLoser They won’t fix it because it doesn’t effect their bottom line. Even if the LTT decides to block these bots all of its previous comments won’t be delete because RU-vid don’t have that option to do that. The best thing to do is to not interact with them and then report them.
The most exotic ram I could see is two insanely overclocked ram sticks with rgb that instead of being individual pieces was a single physical unit that could be entered into alternating slots as per usual and to top it off is cooled by a 140rad and fan for the luls I hope someone makes this monstrosity
Linus do the in-depth MacBook Pro’s like u doing here🤘🏽 A lot of RU-vidr are just hyped by the benchmarks but hve no clue wts wt we want ur deep dive on how Apple did it🤝😅
DDR5's central chip buffer is just like the old DDR2FB dimms from back in the day. Kinda funny how its new people discovering old tech and putting new life into what it can do!
@@Gizmo_- Reporting them does nothing in the long term. RU-vid is the only one capable of doing something to get rid of these scumbags, but we all know RU-vid couldn't care less about issues that doesn't affect their revenue.
I was too until last year. Had DDR4 come out 3 years after I got that PC. Now DDR5 comes out less than a year after I got my current PC lol At least you'll have a nice upgrade waiting for you whenever you decide to upgrade lol
Not gonna use DDR5 for now, so im interested to know about it, since i like to acquire more tech knowledge and experience. I really like your simple approach to explain how the RAM system works! Good Job there, i wonder who had this idea!
That first time I saw DDR as a kid was memorable. It was fast and like nothing I've seen before. But I was always the bottleneck. Never could press those arrows fast enough. Bangin' music though.
I just finished my first PC build and it's so much better than my old one. Thank you Linus for all the incredible tech tips that guided me through my build
I was until 11th Gen. I5 760, DDR3 CL13, and it's still running like a beast! Except every it can do, my 11th does but with less power and 2 extra cores...
"DRR4 is 7 years old, feeling old yet?" Meanwhile, I _just_ bought 2x8GB _DDR3_ to expand my work/gaming PC with a motherboard from 2011, that I also use for VR game development...
I just bought 4x16gb ddr5 trident z5 7200mHz to pair with 13900k on a z790 mobo in a Hyte y60 case for video editing and gaming. I'm excited to see this thing fly once it's finished! ...still looking at the rtx 4090's ...undecided about a few things>> air or aio, brand and series. Zotac, Aorus, Suprim... so many choices!!
A year (at least) from now, we're going to see an increase in actual performance from ddr4 to ddr5. As long as there is no 6400mhz it is not worth it. Not to mention cost and availability. If for the work you do you don't care about the ECC, ddr4 is going to be fine for at least 2 years.
Linus, as someone who designs soft IP, so is familiar with the technical side of this, your descriptions of this stuff are incredible. Very good work LTT.
I've been teaching for 4 years, and this channels fantastic verbal explanation along with incredible graphics to supplement it is really inspirational. Cannot believe I get to enjoy this content.
See what you think about this question. LED light actually flicker. The plate charges and chemical element emits light and the process repeats. So I’ve always wondered if the pulsing LED’s create a RF frequency which could actually cause some interference in the PC’s operation. I would think that all the circuits runs on the board would act like antennas and possibly this could slow the transfer of data in a really good gaming rig. Like build a PC with identical specs all LED’s and the same with no LED’s and see if it makes a difference.
And then there's me, still running Ivy Bridge with DDR3, kind of proud to have managed to overclock the modules from 1600 to 1867... I wonder what PCs will be like by the time I buy a new one, because this 2014 rig is going to hold out until it completely craps out...
Battlefield 2042 has other plans for your pc 😂 I only got a stuttering 30ish fps low minimum settings during the beta with a first gen Ryzen 5 and a 980Ti.
I'm only a year younger with my PC, running a Haswell Intel i5 4460, 8GB of Hyper X Fury DDR3 and a GTX 950 running three monitors, still holding fairly strong. Gonna ride till it dies!
@@jonathonhebert7042 Shit I'm glad I built my gaming pc back in 2019. For $2000 I got a 2080 Ti, I9-9900k, 32 gb of 3200 mhz trident Z ram, a ROG Maximus Hero IV motherboard,and 2 terabytes of storage via m.2 nvme ssd., Just waiting on a new GPU when prices come down.
A lot of people are saying that it will be expensive. I know it is mostly a joke but still. People, new technology is mostly for people that DO have money. Also if you are satisfied with your machine then there is no reason to upgrade. Some people are still happy with their DDR3 computers. Some even with DDR2. Athough we all hate the graphics card market right now exept for miners and scalpers.
I watched the whole video Linus. You did a very good job on this one. Weird question, what does a fan need to do for a free pc? Mine won’t shut down and has been left running for a month now and I miss sleeping in a quiet room. I’ll be insane in another month.
I am so envious of that card, it's also hard to believe that no manufacturer tried attaching full size fans from the best fan guys to a card before. It's been a very rare enthusiast mod for so long, long enough for manufacturers to have heard of it long before now. Maybe it's only happening now because ridiculously thick cards are becoming commonplace.
Me: mom pls i wanna buy the new ddr5. I worked so hard i need it. Mom: we have ddr5 at home. ddr5 at home: *chuckles* ddr5 at home: 1G rAm Mom: enjoy it i used to have 0.000000000000001gb ram at my time.
DDR5 is going to be really expensive at first. If your building a budget PC you might as well just build on a current platform rather than waiting for the next platform. It's going to be a few years until DDR5 is as cheap as DDR4
@@mikeramos91 It doesn't matter if DDR4 is slower or faster than DDR5. It depends entirely on how fast the next generation of CPUs are, since backwards compatibility doesn't exist.
I just wanted to say, you're welcome to everyone who was champing at the bit for DDR5 to come out. I finally got around to building a new computer so, historically, that's exactly the moment everything I upgraded to becomes obsolete. It's a shame because I finally got around to upgrading from DDR3.
Nahh you're good. Most of the time, the only ones that really benefit from those upgrades are power users doing specific things. And DDR5 will be very expensive at release.
There is no need at all to upgrade to DDR5 at this moment. For many reasons. Price, stability, Overclocking limitations of fresh hardware. The difference you can get out of it will probably be unnoticable. Pay attention to the downside, worse latency, that's a huge deal, many DDR4 sticks of a lower price will outperform many of the initial DDR5 sticks.
DD5 won't be at it's peak for another 2-3 years yet. I wouldn't worry about it too much. Even so, it won't make/break your system. Congrats on the new build!
I'm a software engineer, not a hardware engineer; but it surprises me that the CPU would have to wait around for the buffer to be filled with junk to be shipped to the CPU. Generally, software is fine with shipping buffers with "whatever extra junk they happen to contain" as long as a number specifying how much valid data is in the buffer is also sent. I'm not sure why hardware would be any different. My guess is that it has more to do with fixed clock speeds, so even if filling the buffer takes less time you still have to wait for the next clock.
Been rocking a 8GB DDR3 1600MHz RAM on my 4000 series i5 and GTX 970 for 7 years (2014), and just upgraded it to 16GB DDR4 2666MHz 10400F i5 and RTX 2060 this week (2021) -- guess I'll wait for DDR6 to upgrade to DDR5 for consistency sake LOL
Remember that clock cycles is not the measure of time, but the measure of clock cycles! More clock cycles does not necessarily means it runs slower. The speed of one clock cycle depends on the implementation and how the wires are connected on a circuit level, there are plenty of examples of circuits with many clock cycles, but the time/speed of 1 clock cycle is super fast compared to another design.
@@counterstructure4908 I don't know anything about APUs, I just work on DRAM. I also can't say anything specific about it and intend to keep my job, sorry. I don't remember what's proprietary and what isn't well enough to tempt fate like that
Cool stuff working on DDR5, Nate! I’m working on the Adobe cloud as a software engineer and feel like complete idiot comparing it to domains like memory stuff! “Intend to keep my job” :D sounds reasonable. Keep up the impressive stuff :)
I just upgraded from 2000 serious i7 and ddr3 ram, just before the ddr5 come, and i felt little stoopid watching this, otherwise feel so super to upgrade bro its like i used time machine or something to whole new world 😂
@@amystery5238 that's the exact problem I have, I know it's not worth getting anything new, since things already run well on that I have plus I don't play games, but instead use it for office and multitasking. It's just that the pressure comes from all the content on social medias kinda feels like you're left out, when you see everyone's beautiful custom built computers, with all the newest components and stuff.
ACTUALLY, the rig in front of him had Core i9 12900K (shown by Anthony on ShortCircuit) which is still under embargo, I think. So I mean, they had the hardware, they just can't show you.
@@white-bunny THe embargo got 'partially' lifted, theyre alowed to show you the hardware but not allowed to show it in a powered up state yet, or talk about speed findings (cant wait till they can tho, really want to know how the 12900K performs)
When I first started building systems there wasn't even simms. I had to insert each individual memory chip into a socket on the motherboard, 36 of them just to get 4mb. A quarter of the motherboard was just memory sockets. Ah the good old days.
@@jeschinstad So you must also remember the Turbo Button on the case. The forerunner to overclocking. Press it and go from 8mhz to a whole 10mhz cpu speed. LOL
@@nathankennedy3290 I am pretty sure there are fewer than 9 Canadians wishing to be US citizens. Also Canadians enjoy more freedom and liberty than US citizens
I'm not sure how useful it is though, at least the dual 32-bit lanes. If you only need 32-bits. Well, a lot of data is pointers and structures, so 64-bits or more. And that extra data didn't really cost that much more time. For your CPU to just throw it away is probably already included in the fetch cycle. (I'd need to double check but worst case is a bitwise and... so 1 clock cycle of one ALU.)
I don’t worry about those pesky bots. I just report them and let RU-vid do the job! LTT and famous channels have been targets of scams for a long time already and RU-vid doesn’t do anything about it.
those metaphors were impressively mixed. Should of had a link to Ian Mccullum's minigun teardown so people could figure out what you were talking about lol
