"As the channel gets more popular, the questions keep getting stupider"

I'm one of the "stupider" viewers, and I'm fine with that. It's why I watch your videos, so I can learn. Thanks for all you do!!

One good reason to go with an asymmetric memory configuration: you're on a laptop and they soldered one of your memory sticks right onto the motherboard.

That whole opening made me LOL. And I didn't think buildzoid could get any better 🤣

You're the man! I'm learning so much by just watching your channel. Before too long I'll be a computer scientist lol. Thanks for all you do, my dude

Love the round up/conclusion at the last 5 minutes. Great video.

"can I ask a question?" "yes, thanks for confirming there are more stupid question on this channel" ;-)

Hope more people come back to watch this video. With all the current talk about memory ranks, this video would help a LOT of people.

Great video! Thank you, was particularly interested in how the ranks sat together.

Intro and ending made me cry :D and the whole in the middle..made me recap everything Thanks BZ !

FIRST

i love these type of videos, get an opportunity to learn more ,guess that why it is said "He who asks a question is a fool for five minutes; he who does not ask a question remains a fool forever." Keep making such videos they really help a lot.

7:18 Intel glued together two lga3647 xeons and that has 12 memory channels. Its called Xeon 9200 but nearly nobody uses it.

love a nice long Rambling video, GOLD. time to grab a coffee and sit down.

Educational, concise and down to the point. You Sir helped me make an informed decision with my hardware purchase. Thank you very, very much.

I just watched a man take an entire minute to say the words "about 90%".

u see a 40min video.... I see the next 5 days of good sleeping :D

very informative video as usual ! thanks for taking your time to share the knowledge :) Got a question... why not making an overclocking video on those 3600 cl17 kit " b-die " on Ryzen cpu? im really interested to see how it will perform

I love learning from your "Rambling" videos.

Thank you very much! This was very helpful - my laptop had 4gb soldered and one 4gb stick. I kept hitting the page file, and was worried about mismatched sticks. Got a 16gb stick to swap it out, and I've had no noticible performance loss.

Excellent video, thanks for posting

Finally someone who doesnt confuse pagefile with pagetable :) that made me happy, thanks

This is the only video that actually explained these concepts. All other videos just explain for one minute and then just show benchmarks and gameplays for the rest.

perfect explanation, thank you. also a perfect refresher to watch on 2x playback

awesome explanation again, thanks!

Hello and thank you for very helpful video! Question i have is Do you prefer with AM4 and daisy chain 2x16Gb dimm's 2R OR 4x8Gb dimm's 1R? Is there any noticeable difference like in overclocking?

Can I cut a memory stick in two and use each half on a memory channel? I have a pretty neat Xacto. Now seriously. Can you dive more on those more obscure settings such as Interleaving and BankgroupSwap? I have a 64GB 4 dimm kit (TridentZ Neo 3600 CL16) running at 3733 CL16 and I wonder what else can I do to improve it. My timings are already as tight as I could set them. Also would be good to know which parameters are the preferred ones (besides primary) to further lower latency. So far I know primary, tRCT and TRFC are good candidates.

i love buildzoid's "i'm telling you this for the 1000th fucking time" voice. never change!

I actually learned a lot out this answer for that stupid question ahah I like the good work

You have no Idea how useful this is to me, I'm focused more in the server part which is a shame that you didn't talk about, but nevertheless this was great. Maybe a little more examples on the rank side would have been good but I can already clear my doubts by myself

Thanks for the explanation. Since I didn't understand it well, I had been wondering if you could run one of those DC DIMMs on an X99 ITX to take advantage of all 4 memory channels across the 2 connectors it has (sort of like how you can run two PCIe cards on one connector with bifurcation). This video has answered that question.

I just come over this searching for ram for my ryzen gen 3. Very helpful. Thanks a bunch!

hey Buildzoid! I have a very weird scenario and would love some help deciding if I should return a new kit. I basically got a Micron 32GB 2x16GB 3600 cl18 kit that was the exact same model in the shop page as the one I had already, but this ended up being a different _submodel_ with not only different rank (dual vs single on the old) , but also different PCB (samsung B2 vs Hynix A2), rev E vs rev B (micron), 17nm vs 19nm, different row addresses... the works. The JEDEC tables es also slightly different, but XMP profiles are the same, and so are voltages and whatnot. My issue is these 2 kits, which are installed paired in the two respective channels of my Mortar Max B450 (3800X on it), have trouble booting with XMP. I can only consistently boot them consistently after multiple attempts of resetting BIOS, going from 2400 (JEDEX) to XMP but also manually setting RAM frequency in advanced to 3600. I also managed to use XMP then manually set 3200. It does seem to stay consistent after it boots to OS once, but I fear I may have trouble in the long run. I also did not do a thorough memtest on the 64GB setup, but I've had no freezes or restarts the week I owned it. My question here is if I should be returning these (shop provides a month) and look for the exact same submodel kit. The new stick was 40 euro cheaper than the old one from 1y ago, so I guess I learned my lesson. I also know I should not be getting 64GB over 2 kits and sell my current kit instead to get a 64GB kit, but I don't need absolute performance, I just happen to have a use case where I need 64GB for virtual machines building Chrome and Android and whatnot.

Well ahhhh yea, love the video.

I feel like I learn so much and nothing at all but I am compelled to binge

ignorance != stupidity Ignorance = not knowing something Stupidity = being unable to know something

Oh that s a good explain man !!🎸🤸🏼‍♀️

You should make a whole series about how cpu works in a very detailed manner !

You explain things much better than Wikipedia ever does, so keep making videos like these

How do you know so much about this stuff? Do you have a electrical engineering degree? A computer hardware degree? Just want to know how you know so much

Well I was looking at info for Dual Rank and it's was a great explanation. I'm sure better then Wikipedia. Good job

I've seen 3% to 15% performance increase from single to dual rank because of interleaving. Latencies can affect how much of a benefit can be had, obviously.

great, my laptop has exactly 12gb of memory. I thought that was weird. So if I am understanding this correctly, if I have a dual channel Ryzen 9 3900x and I want 32gb of memory, while it would be more efficient to have a 4x8gb configuration I would have better performance due to higher possible clock speed using a 2x16gb configuration, filling only 2 ranks. If I end up needing more capacity (I am a gamer who is also a programmer) I could add another 2x16gb later and fill up all 4 ranks but I would likely have to drop the clock speed. Great, now I just need to know if I should target B die or CJR (looking at the gskill neo's at 3600 mts. Shooting for 3700-3800 mts, but I don't know how well CJR does. I hear it is good for clock speed, but the timings suffer and that B die is so much more expensive. Memory makes my brain hurt :/ Thanks for the breakdown, this was helpful.

Because some of us actually like to hear you ramble. That is why you had to make this video. lol. I don't know, maybe it's just me, but I like that you don't edit your videos. Makes me feel like I'm right there just hanging out there with you.

I'm in the 48gb camp. Got 4 sticks of 4GB Adata XPG Gammix D10 2400mhz (AX4U2400W4G16-DBG) in July 2018 for 164 USD when memory was insane stupid expensive. In July 2019 Newegg was having a sale on 8GB OLOy 2400mhz (MD4U082417IFDA) so I picked up 4 sticks of that for 90 USD. Nearly half the price for double the capacity just a year later. I really got bent over in 2018. Anyway, I run all 8 sticks in my X99 Taichi with 6800k at 4.2ghz 1.275V and have overclocked the RAM slightly to 16 16 16 36 timings.

Did buildzoid do a video on 4 dimms in the x570 unify yet?

Ok you have to choose wisely: AdoredTV 50 min. Video or Buildzoid 40 min. Video, oh boy... XD

0:30 angry mood intensifies

No one: The Verge: Look, our PC is so fast it doesn't even need dual channel configuration! We even needed to LIMIT fps in game so the PC doesn't explode!

Before I was using a workstation board with 128GB ddr4, I used to run 2x8 with 2x4 ddr3 on my old AMD system. Worked no problem.

Ey man maybe its a stupid questions but I have a doubt with my motherboard is an Rog maximus apex and it have two dimms slots and it have like a third dimm slot looks like an slot of ddr3 to install 2 extra m. 2 disks. Im planing to equip It with 2x16 dual ranks gskill. My question is if this slot for the m.2 disks is controlled by my memory chanells if I Will loose max frecuency or bandwith or something..

I assume socket 1700 fits in line of the others in the LGA group? Or has Alder Lake different useability?

Ho wdo you test the stability of the Infinity Fabric if you want to try and up the speed of it?

Higher ranks wouldn't reduce effective speed instead of the max? For example if i have a 1 rank dimm that can theoretically go up to 4k mhz but working at 3200 mhz in one slot, if i add another one in the same channel it will be 2 ranks so they will work at < 3200 mhz.

Hello, may I please ask you a hybrid (stupid and tricky at the same time) question?: I am looking forward to buy a Thinkpad T14 Gen 3 with i7-1260p, dGPU MX550 and 16GB 3200 RAM soldered to the motherboard. This laptop model also provides one empty DIMM slot for the dual channel capability. I want to add another 16GB RAM into it. Given that Gen 3 (as Gen 2 and Gen 1) comes with single Rank soldered memory, which RAM stick should I go for: 1Rx8 or 2Rx8? Like, what would be a better solution: 1) M471A2K43DB1-CWE 16GB 2Rx8 PC4-3200AA SE2 11 (or xxxEB1-CWE) ((I couldn't find any info about the difference between D and E dies)) 2) M471A2G43BB2-CWE 16BG 1Rx8 PC4-3200AA SA2 11 The first one is dual rank which is probably better in terms of utilizing capacity, but is it neccesary concidering soldered memory is single rank? Or maybe the second one is better because of B die and retaining the clock speed? Lenovo support could't provide me any useful information, their website have both types (1Rx8 and 2Rx8) memories available as alternatives. Thank you in advance for your time answering my question and looking forward to get the right answer :)

I mean I didn’t even know what dual rank memory was until like a month ago and had put together about 10 pcs

I've heard that non-k intel cpu memory controllers have sorta locked voltage so OC is not that great, then does it mean that dual rank memory is better than 1rank with something like 12400 even if you're overclocking?

question : both arent ideal but u said the cpu sees quad rank as 2 sticks , so 2 actuall sticks in single channel (dual or single rank ) vs 1 quad rank stick which is better?

You said there you have done a video on "memory topology" in the past. Where is that video ??

Has anybody gotten their hands on the new 3000 or 3200 Ballistix kit that's replacing the old AES kit? Is it a good overclocker like the AES kit? Here's the part number BL2K8G30C15U4B

"As the channel gets more popular, the questions keep getting stupider" That's it - it took me a whole thirty seconds before I hit the like button.

Great Video (y)

inb4 ram manufacturers add a second connector-"leg" to a single DIMM so that it has twice the connectors and plugs into two DIMM slots (because reasons of course)

Huh, my HP Omen laptop came with 12Gb. Now I'm curious if the times it really bogs have been when over 8gb workload.

on my 3200 c14-14-14-31 dark pro b-die, setting manual timings for everything while running xmp clocks and primaries on my 6700K, I can get an effective bandwidth of 96% on reads and 97% on writes of theoretical max bandwdith, getting 49.1gb/s for read, and 49.7 for writes, theoretical being 51200mb/s

Fuck, now I have to go watch the memory topology video. Brb.

So now I wonder- if there's such a massive performance improvement going from 1 channel to 2 channel, why isn't higher channel support there for more common consumer chips (like Ryzen 5, 7, intel i5, i7, etc running quad channel)

so in the situation of 48GB does it go like this (8/8/16/16) or like this (8/16/8/16), ram is the same in everything but the size

epic as the channel gets more popular, the questions get stupider

so what better: all four slots with single ranks, or 2 slots with dual ranks?

re: APU and memory bw: on the distributed computing project World Community Grid, i had about the same points per day (PPD) with 1x2400 stick vs 2x2400 stick. or no worse than 10% slower on a 2400G. running a GPU project along side it was 20-30% fewer PPD, tho. also, on my Threadripper 1950X, there was little to no difference between dual and quad channel or again no more than 10% fewer PPD. basically, you couldn't see the difference on a spreadsheet.

The only thing missing from this video is: Why is multi rank bad for frequency? I'm wondering if it is because of the different length/runtime between the ranks, but then using dual rank sticks would not be impacted ? And if so, same for T-Topology? Would love to understand the relation of ranks to overclocking.

You got the rambling part right.

So do I have this right, when a motherboard says 1DPC 1R that means that I can only put 1 stick in each channel, thus NOT being able to fill out all 4 DIMM slots?

I will be timestamping useful parts of this video for my personal use, but you guys can take advantage of them as well 0:38 Memory Channel Explanation Start (Mentions the difference between a connector and a connection) 1:16 Visualization of channels/more explanation Important Distinction - This video will not be reviewing memory topology, seeing as Buildzoid already made a Faulk video addressing that. 2:27 Maximum theoretical memory bandwidth of memory channels (inc. formula)

I have a 2700x with a x470 taichi. I started with an old vengeance 2x8 gb b-die v4.21 (3200mhz cl 16 rated) on it (from 3 years ago), never went over 12gb usage but wanted to populate all the 4 slots for the t-top configuration of the mobo (not daisy chain). Found 2x4gb vengeance (3000mhz cl15 rated) used for 40€ and put them on the config. As you said no problems here with 24gb, I even managed to go down from 3000mhz cl15 to cl14-14-14-14-28 T1, that I couldn't do with only 2 sticks, t-top magic I guess. Ps the memory controller on my cpu sucks, I can't manage any type of ram at 3200 without stability issues (it boots, too many errors on memtest even boosting voltage and cl)

i am using hp zbook 17 g3 with 4 ram slot and Intel(R) Xeon(R) CPU E3-1535M v5. can i mix RAMs of different bandwith. currently i am having 20gb RAM (8gb 2400T, 8gb 2133P and 4gb 2400T all being 1Rx8). can i add 16gb 2Rx8 2666v? all memorys are DDR4. when i checked my CPU memory support on intel page i see; DDR4-2133, LPDDR3-1866, DDR3L-1600

Is dual rank or single rank better for 16gb ram (Should I use 4 x4gb sticks or 2 x8gb). The dual rank has the double the access via DIMM slots. Meaning each stick can use the full bandwidth of a single lane. Use the four by four GB sticks. ez enough Unless you are chasing high frequency

So apparently zen 3 is one of those "weird cases" and now I'm still unsure, is it better to get 2x 16gb dual rank, or 4x 8gb single rank for zen3?

@AHOC please help me Biuldzoid ... I ordered G.Skill 8x4 CL14 F4-3600C16Q-32GTZR alongside with X570-E Gaming from Asus. Please tell me that will it run at 3600 @CL16 or not? . ( CPU is 3950x ) thanks for the video.

X4 memory sticks do work on LGA1151 but the iGPU will be very unhappy if you run them. There are modded sticks that are 1Rx4, they are ok TBH, especially the ones with Samsung B or C-Die, they OC to 3733 albeit with loose timings.

So dual rank configurations are good for AM4 because memory overclocking isn’t really a thing on AM4? Or because you don’t want to overclock past your fclk? But what if your fclocks can go higher than your memory stock speed? Would dual rank memory config hold back your clock speeds? Does all this really matter to those who want to extremely overclock their memory past it’s rated speed?

what i am trying to figure out is the memory purchase for my next build... everytime ive wasted money on higher "mhz" than i needed. i am trying to avoid this... i am planning on purchasing the 7950x3d sometime after release so i am looking at the 7950x specs... it says it supports 5200 2x2R w/ two sticks... and 3600 4x2R w/ 4 sticks... which in my consuming eyes looks like 64gb of 5200 vs 128gb of 3600... however there is no DDR5 @ 3600... therefore i am confused AF. anyone got answers or advice for me? should i just buy 4 sticks of 5200?

Running 24gb on Ryzen 3000 4-8-4-8 or 8-4-8-4??? Identical samsung single rank b and d?-die, xmp's are the same. Any idea? Thanks. These are 3600CL18 sticks, R5 3600 can only run 4 of the stable @3000, i have 3950X on the way, hoping it will have better IMC so can run at XMP..

Is it the case identical when using ddr3?

pagefile is something not a single tech "guru" talks about it's just "more memory can"t speed up your pc" BS finally a voice of reason that sees the problem with pagefile

might be a silly question: going from 2 to 4 sticks would require reducing clock (4400 -> 4000mhz), does that apply for slower speed sticks too (i.e. with 2*8gb 3600, adding another 2 sticks, won't run 4*gb 3600 and require reducing clock to i.e. 3200)?

I did not understand why to prioritze the frequency over rank?

I was thinking hard about what stupid question to asked that you answered before and I finally got something so here we go: Should we buy a 2x16gb memory for Ryzen or 4x8gb. And thanks for the video ;-)

I interpreted your opening statement to mean "you can't run dual channel using two sticks with more than one rank" and it surprised me. Listening to it again after the whole thing I realize you mean a single dual rank sticks can't utilize both channels. I assume?

aprox. 10% diference between 1R to 2R, according to the benchmarks. and 30%~60% from X16 to X8

This is Only 40 mins long? Where's the other 20 mins? I feel short changed.

Lol, that intro flame was predictable for the regular viewers but it good he makes another video about it. Doesn't hurt to answer questions (mildly sincere)

I need someone to teach me about downclocking high speed kits say one has a mobo rated for 3200MT/s and looking to buy ram, prices of the kits are negligible. kit1: 3200 CL14 kit2: 4400 CL19 what are the chances the 4400 kit will get close to the 3200 timings when downclocked to 3200?

Q: if 4 ranks is a 16GB stick, what do they do to accomplish 32GB on a single stick without hitting that power limit you were talking about?

I'm one of the weirdos running 3x3 ranks (64GB 3600MTs) on z590 (11700K). I actually tried to buy 4 dual rank sticks, but the retailer sent me one kit of single rank and one kit of dual rank, even though I ordered two kits of the same SKU... Weird.

Riddle me this: I have an i-7 laptop with 2, 16 GB so-dimms of dual rank DDR4-3200. (As per CPU-Z) The RAM works in Dual Channel. I have an i-5 laptop with 2 unequal so-dimms. 4 GB DDR4-3200 is soldered on the motherboard. And there is a 16 GB DDR4-3200 single rank so-dimm in the only RAM slot. Does this laptop run in "partial" dual channel, (up to "matching" the 4 GB on the board?) And then use the remaining 12 GB (of 20 GB) as Single Channel? How DOES that work? BTW Windows Task Manager says I am only using 25% of available memory. But it also shows a lower clock speed than 3200. Cheers!

BZ in 2020: "ECC is servers" JEDEC in 2021/2022: "SAY NO MORE" (DDR5 is getting ECC)

Can you install your RAM inside your CPU if your dual rank has only one layer? I checked, and my dual rank on has one layer.

hmm not sure about my purchase of two 32gb sticks for my x570 board now, sounds like doing 4 8gb sticks would have been better
