Always get the fastest, most expensive bleeding edge so you can be an unpaid tester and make things cheaper for me.

[@monketok141]

But then the manufacturers will see all that demand and then know they can charge more 🤢🤢

[@FirestormX9]

If you think you are gonna get anything relevant for 'cheap' from these manufacturers then you might as well just use an abacus.

[@bsigns1935]

the holy answer of all questions

[@Stefan_Payne]

...what's available, on sale... If you go with an AM5 System and DDR5-6400 is on sale and DDR5-6000 is the same price or more, go for the 6400 Kit (in my Case: CL32).

[@dmhzmxn]

What speed of ram should I get. "it depends" "depends on what?.." "use case..." yeah if someone answered with just "it depends" and doesn't explain and actually answer my question, I stop talking to them and find someone else to help lol I don't deal well with utter incompetence.

[@Stefan_Payne]

@@dmhzmxn No, Situation in the store. If DDR5-6400 CL32 is the cheapest and DDR5-5600 is just 10€ less, you get the 6400 CL32. You don't get a DDR5-4800, 5200 or 5600 for 90-95€ when you can get 6400 CL32 for 105€. (Mindfactory right now) That is what it depends on

[@JoeBob79569]

That actually makes a lot of sense about the fact that if the CPU is busy then ram speed won't really matter as much. It's kind of like the fact that it doesn't matter how fast people in the queue move at the DMV, because it's more about how fast the person behind counter can work.

please make a LTT video on pc servicing and maintainence which is very much needed to the average user who has to do it on their own , this include proper gpu cleaning with changing thermal pads ,thermal paste , cleaning the fans and heatsink by removing all the screws possible ( you can include this in advanced cleaning) , cleaning all the case fans , cleaning psu , cable manage , etc ,etc , would also like to know how LTT maintains their pcs across their office ??

[@majocmd]

This would be amazing video, even something longer for main channel. Something you could do regularly, with physical maintenance and maybe even software maintenance like updating, chkdsk and similar stuff that might be useful. Something you could watch every time you clean your PC like a checklist would be top notch.

[@ts757arse]

For the average user? Clean dust filters. Ensure fans spin.... ...that's about it. You can air dust the inside if you want. No vacuum cleaner. Thermal paste and pads only if you're seeing issues or the paste is very old. Otherwise you won't see any improvement and you're risking damage. This is not a routine maintenance item unless you're an enthusiast. The average user will see no benefit unless parts are very old. As for software updates... Yes. Do them. Don't bother with anything else (like registry cleaning) unless you have problems as, once again, you're likely to create them. For the average user, there really isn't much to do and every time you poke around, you're risking ESD or just plain jabbing something with a screwdriver. It's fine if there's a need. The one thing the average user should do and never does? Back up. Sod the cleaning, the thermal paste, the drivers... Back it all up monthly. Image your drive or something.

[@kingzach74]

UFD Tech has some videos on computer maintenance. You should check his channel out and search his channel for maintenance.

Was expecting some meaningful graphs to show the difference between the DDR5 speeds in different games/ programs but I guess a vague "more isn't always better unless you need it" is the best you guys can do

[@gorzius]

Well, the channel is called techQUICKIE for a reason.

[@TheAnon03]

latency tends to be an issue in games like Dwarf Fortress and the like (Rimworld, Stellaris, etc), there's so much being kept track of that the amount of time the CPU spends talking with the RAM can actually build up and make an impact. In those situations it's not FPS but ticks per second.

[@Stefan_Payne]

Simple: You should buy what's on sale/makes sense for you in that moment. I bought a 32GB Kit DDR5-6400 for my AM5 (7800X3D) because it made sense. As in: other kits wouldn't have been cheaper but worse. So I got that because it made sense at the moment.

[@gezimlimoni2319]

And what kit did you got,,,link?

[@colly6022]

Good video, but I'd love to know how DDR5 speeds affect other tasks like code compilation. Some languages' compilation pipeline involve more memory intensive tasks / data structures. For example, Rust needs to access a data structure to figure out stuff with its trait semantics and ownership, and JavaScript (although not compiled) involves a lot of runtime type-checking. Web DOM manipulation (especially in React apps) also requires a lot of non-contiguous memory access.

[@aleksaalargic4212]

This is too technical of a task for LTT to perform, they mostly look at gaming.

[@deepblue812]

The real answer in 2024 is whichever RAM is listed on the QVL from the motherboard manufacturer. Have had compatibility problems too many times in the last few years not to check.

[@dafyddthomas7299]

So true on this - finding out to my cost whilst trying to repair / upgrade older PC's and sometimes with PC pre DDR-4 hard to find components that work and reliable, even if you get a part advertised as being cosher doesn't mean it it and will work reliable if the PC in Q - much to my %^%^^%^% being bit green - coming back (2005-6) after break into building / repairing PC's - learning the hard way as well.

[@CommodoreFan64]

Yep it's been that way on AMD since the DDR3 days when I pushed the 32GB RAM paired with my A10 7870K APU OC @ 4.3 GHz to 2133MHz to squeeze every drop of performance I could out of that turd(still have it as a backup).

[@Bob_Smith19]

QVL lists exist for a reason. Buy a kit that’s on your MOBO QVL list. If you don’t then it’s on you. They did the leg work of validating those kits.

[@helloweener2007]

Yes, but "2. Memory modules listed below just for reference only. Considering multi variety memory models in market, we can only verify some of them." Not always are all modulöes on the list, even from the same brand. Sometimes certain seizes are left out but kits with same chips and timings but bigger / smaller RAM agree not on the list. You can use them as reference when they are not on the list.

A quarter more are not available in countries that aren’t in Asia. Leaving you with very few QVL options. Usually of a size and speed that isn’t acceptable. When my X470 motherboard came out, the largest ram stick on the QVL was 2GB. Meaning I could only have 8GB of RAM if I followed the QVL. Utter nonsense.

The responsiveness is a noticeable difference between the 2 speeds. This is paired with my 13600k @ 5.5ghz all p-cores, and 4.4ghz all e-cores, with a 4.9ghz ring cache.

[@VladimirDT]

I got my ram during the LTT crossover with Lexar. The weird thing though is Lexars manufacturer name does not appear in the bios. All the timings and everything are correct and work properly but the manufacturer label says "unknown" dont know if thats cuz Lexar isnt one of the super big ram guys or what. Bios update didnt do anything either

Dont blame you, i went from 3 to 5. 4 is still good. Just a warning though, the beginning of a RAM generation kinda sucks, DDR5 doesnt handle quad channel very well and i havent seen a kit that can get quad channel at full speeds. So just plan on getting 2 high capacity sticks. DDR5 is also is apparently more fragile and you have to be more mindful when putting them in the PC, im going to guess that ddr6 will be even moreso.

[@bioniclelegend7]

Thank you for pointing out max memory speeds of current cpus. I will be honest I made a blunder with my new pc part order, ordering 6000 mhz ram for the 7800x3d but watched this video again just to make sure I was getting the right speed and realised I should get 5200 since you pointed it out.

[@asamodi6401]

No you shouldn’t get 5200 MT/s, that’s just the official maximum speed to insure stability. 6000 MT/s is very stable as well, but it might be a little less stable than 5200 MT/s. I guess it’s their way of saying “we don’t guarantee stability for anything above 5200MT/s you’re on your own if you have any issues”

[@MoreOrLessUA]

Short question - does intel integrated graphics work on 6000? Context for my question: Intels integrated graphics is really helpful for video editing thanks to quick sync. But currently I am using i7 6700k and ddr4 memory with 2800 xmp profile. But as soon I am activating integrated graphics in bios - I am getting bsods. When I am dropping memory frequency to 2133 (which is listed in intel ark as standard) - it seems to work fine. For newer ddr5 processors - it is listed 4800 as standard, so again, will the iGPU work if I go higher? Thanks in advance.

[@jacobkelley257]

What about a video on memory swap? I am using Linux Mint and noticed on my "task manager" with the RAM usage graph, there is a second line called swap. I looked into it and learned it was just taking some of my storage, which I have a lot of, and using it like RAM when my real RAM overflows. Kinda cool, and potentially very useful for someone with low amount of RAM. While of coarse it's nowhere near the speed of real RAM, it could save your bacon in a particular situation. Also, apparently you can do it in windows, and presumably macOS, so that's cool. For no reason whatsoever, I have my swap file set to 64 GB. On top of my 24 GB real RAM (one of my 8GB sticks went and corrupted itself).

It gets more complicated with AM5 platform now. It is still very young platform expected to last 4+ generations of processors where each processor is expected to support faster RAM than previous gen. So if you buy ram today for first gen AM5 processor you should take into account that the same RAM will be used by newer AM5 processors in the future, which will have higher RAM sweet spot than current AM5 gen.

Well here is what I learned for AMD zen 5 processors the Max speed you should consider for dual channel is 6000MHZ, anything more and the controller will get stressed (ideally I would go with 5200MHZ as recommended by AMD to ensure best stability, however 6000MHZ seems to work well). If I were prehaps maxing out all the ram slots with DRR5 then I would get the slowest one possible at 4800MHZ knowing that the controller is going to most likely downclock it down to around 3600MHZ. Hopefully zen6 will have better memory controllers.

Be honest. Did you interview someone for LMG who was playing Counter-Strike in the other window?

I allways buy 1 step,up that the next cpu (intel) w I'll need as default, ie 6500, or 6300 ddr5. When ddr4 2133 was out I'd get 2666, next intel cpu was 2666 ram speed etc... At least when your re use your ram, on next upgrade, your faster ram will run default on next cpu. (When first 2nd and 3gen ram speeds come out.)

[@deeomayall]

Also... 4:44 - a stab at SBF? :P

[@honestgoat]

Lol. Plot hole. Apparently they were gonna explain where the 6000Mts number comes from after the sponsor. Did I miss it or did they forget to add that part in? For those that are interested: In traditional SDRAM (Singe Data Rate) data is transferred once per clock cycle. But in DDR RAM (Double Data Rate) data is transferred on both the up and down signals of the clock cycle. So DDR5 6000Mts RAM runs @ 3000Mhz but transfers data twice every cycle. So two transfers, 3 billion times a second. ie 6000 million transfers per second or 6000 Mega Transfers per second. Hence the rating 6000Mts. So to work out the memory bandwidth we need to know how many bits of information is transferred. Typically DDR4 and DDR5 use 64 bit data buses. So with each transfer 64bits can be transferred. So 64bits, 6000 million times per second. Which 384 billion bits per second (384Gbs). Then you get into Multi Channel memory configurations. Most commonly dual channel and quad channel on consumer boards. Each channel allows for simultaneous transfers different memory sticks. Thereby increasing the memory bandwidth. Dual channel doubles the bandwidth, quad channel quadruples it and so on. These days, servers use 8 channel and even 12 channel configurations for memory allowing for incredible amounts of memory bandwidth.

[@damonguzman]

Slight correction: RAM speed 100% would make a difference in AI performance if you are trying to run a model too large to hold in VRAM (so you offload model weights to RAM). AI is already bottlenecked by GPU Memory bandwidth and not GPU compute. Since the GPU memory bandwidth is more than an order of magnitude faster than CPU RAM and it’s a bottleneck, offloading to said RAM will DEFINITELY be improved by improving the memory bandwidth.

[@deeomayall]

Doesn't CUDA throw an exception if the entire model doesn't wholly fit in VRAM? Otherwise why the rush for high VRAM? OK, I'm assuming there have been ways around it (an AI version of ReBAR?). Still, bumping up the system RAM bandwidth wouldn't make a big difference for weights that go in and out of system RAM at a tenth of the speed they should have. Now, training data, that's another story. Faster RAM will get the minibatches to the GPU as quickly as needed. Although - PCIe bottleneck....?

[@deeomayall]

Ok, this is just a techquickie, but still: - You cite AI workloads. AI training is likely to run on a dedicated GPU, and system RAM is there only to feed the VRAM in that case. If you use an NPU, though, or even integrated graphics, the system RAM throughputs contribute to feeding the processor with minibatches, so I guess you'd want good throughput there to get as close to VRAM as possible. - RAM latency and real-time audio. So, presumably the sound card will populate a buffer that lives in system RAM. Assuming that an audio buffer can stay within a modern processor's cache, the initial transfer will still carry a penalty of 10-18 ns depending on the memory timings. 8 ns isn't negligible when you're trying to meet a real-time latency of 2-3 milliseconds. I'd like this use case to receive a bit more airtime, as it's all but niche. Loads of people record stuff at home, and they struggle with crap latency and buffer underruns.

It might be over 6000, but...is it *OVER 9000?!?* 😏

[@kyoshimtl]

Your RAM is fast, or is it?

[@zackzeed]

For DDR5 5200, 5400 is totally fine, 6000 seems to be the sweet spot and everything over that gives you slightly better numbers in some games but it's a 4090, you pay way more for a little more speed so to speak. Well depending on where you live of course. Generally; US = "cheap" and EU = very much Not cheap LoL. Oh and RAM that is faster than 6000Mt/s (and especially even faster than that) is generally not recomended if you don't have a motherboard + cpu combo that can handle it. Well, even then it's almost like the silicon lottery. Edit: Latency is good and all but when it comes to DDR5 speed is more important than Latency ( CL 32, 36, 40 etc... )

[@dvast4942]

I have DDR5 6400, I didn't even knew it was technically unsupported, anyways it was almost the same price as the 6000 and same timings so it made sense to get the 6400 instead of the 6000

[@gezimlimoni2319]

What speed you running them stable,,I'm about to get the same

[@danielsjohnson]

Why do you need to multiply by 8?

[@LittleMopeHead]

I just hate that with ECC ram, it's "supported but depends on your motherboard manufacturer". The only way to know for sure is to buy and test.

[@TheSimRacers]

Still waiting on the UDUMB socket….😂

[@5urg3x]

I still can’t figure out why my system won’t do 5600 and caps at 5200

[@Hyper445]

If only this video came out like 2 weeks ago when I bought ram for my new PC, luckily I got 6000MHz!

[@Akkbar21]

Even the ddr5 5600 cl36 I got in Oct ‘22 is good enough. I lose a few fps compared to 6000-6400. It’s fine n

[@adriancoanda9227]

the last sentence was elite imagine having 8 monitors if 16GB ram is utilized in windows ca 90% with iGPU i think for gaming you will have to think about 256GB cause it is not just the game you are running also ram usage depends on the platform

[@la3692]

It also depends on the board you're using why don't take ddr5 any faster than 5200😢

[@ibn_3rb]

Where's Mr Cool Mustache ?

[@HokgiartoSaliem]

3:41 Why AMD drop their speed if used with 4 memory slot, while Intel is ok?

[@Ethan7_7]

Me watching this with DDR4 not planning to move in years: interesting

[@XxxTheFireEmblemxxX]

why has nobody in James' life ever taught him how to line up his beard? It's brutal, dude.

[@shaggytoph]

I tried re-watching his beard and it looks awesome, don't know what you're talking about. Are you a barber perhaps?

[@idk4399]

the fast one

[@Canuck-1976]

Here am I on DDR3 3200Mhz 32GB. I will upgrade, obviously when I get my my new CPU.

[@ForTN0X]

When it comes to gaming it is only importent that your system is better than your friends systems. Only better is better here

[@goateatingpie9813]

6,000 MT 30 CL

[@Rmm1722]

Wow 😲

[@LA-MJ]

1:37 factcheck multiplication

[@niteshdalvi4381]

I m already using DDR 7
