find it funny how ive been watching videos on PC's for like 4 years now and not once have i heard someone mention the dual rank stuff till now.

[@JustAGuy85]

Dang, been running dual rank RAM since as long as forever. I didn't KNOW why at the time, but I ALWAYS chose 4x4GB or 4x2GB set ups back in the day until I finally learned about dual rank. I preferred the lower timings of the RAM and always seemed to have better performance than everyone else with two sticks. Dunno if it was a dual rank thing OR if it was just the lower timings. everyone always moaned about the memory controller struggling but I never had issues with that. Sure, I didn't have an upgrade path for more RAM, but I always threw in more than enough to hit that sweet spot that was always more than enough until the system was obsolete. Now I'm running 2x16GB DDR4 3600 C16 dual rank RAM (G.Skill Ripjaws ending in GVKC). But does Zen 3 support quad rank or not? I'm curious because I'll buy another identical kit just to have quad rank lol. Just not sure if Zen 3 consumer chips support it... I'm on a 5900x. Obviously Zen 3 consumer chips only support dual channel, but what about quad rank?

@@_Booker_DeWitt I actually got 2 more sticks a few months back, 64gb now, I'm unsure whether it's the 4x2 ranks or the Ram upgrade, neither are obvious to me, but I tested some games and my minimums were better on 64gb. Now I've heard that upgrading Ram generally improves things as there is less stress on the drive, can store more stuff in Ram, and it will compress stuff less, but idk what actually caused it. Far Cry New Dawn also had massive stutters on 32gb not apparent on 64gb. I'm guessing like you said, it was the Ram capacity. This is a weird one, nobody seems to talk about 4x dual rank sticks.

Having 4 dual rank sticks also stresses the CPU’s memory controller and can limit max ram overclocks.

[@deleater]

I don't understand one thing. If the data bus width is 64-bit per channel and in a dual channel platform you have 128-bit wide bus together regardless if there are two of four stick of ram then how can having a single or dual "rank" make any difference in effective memory bandwidth? Please someone explain! May be I am missing something!?

[@ToTheFuz]

@@deleater I'm definitely not a professional so take what I say with a grain of salt as this is my 2 cents. Ram has a refresh rate, so it can only be addressed by the CPU as fast as that refresh rate allows. If you have two sticks of memory in dual channel, the CPU can pull a string of information from one channel (one stick of ram) whilst the other channel is refreshing (the second stick), and then in the next clock cycle the first stick of ram refreshes, and second stick is able to be addressed. In the case of 4 sticks of ram. The CPU can pull 2 strings of data from the same channel per clock cycle rather than just the one as the CPU can now fetch from two different addresses in two memory modules. Of course this wouldn't exactly double performance or anything, but could help in memory dependent applications.

[@RicochetForce]

@@ToTheFuz You nailed it. IIRC dual rank memory enables memory interleaving which I think is the name for what you just described.

[@kognak6640]

@@ToTheFuz Each memory channel works independently from each other. They work simultaneously just fine, you wouldn't get combined bandwidth out of memory otherwise. Memory ranks are different thing, they are sets of memory within one channel. A 16GB dual rank module has two 8GB sets. Two single rank modules(in one channel) does same from memory management perspective. Performance benefit comes from ability to access different rank while first one is still doing previous memory operation. But still same bus at same clock speed so it's not big difference. Quad rank means there's 4 sets of memory in one channel, you need two DR modules for that. It's not memory interleaving, interleaving is between memory banks(subset of rank).

[@JustAGuy85]

I always heard that was kind of a problem on the FX Bulldozer/Piledriver CPU's. I wonder just how much it actually effects stability on, say.. 4th gen Intel CPU's or 7th gen Intel. Or 10th gen. Not gonna name 'em all but, yeah, just curious. I always preferred having 4x sticks. I purposefully bought 4x4GB DDR3 1866mhz for my FX-8350 rig years ago. Only one game in my life ever needed more than 16GB (DCS: World), but it ran fine with 16GB for the most part. But, yeah, if I wanted more than 16GB, that wouldn't have made things easy. Then, again, that system had Windows 7 Home Premium so 16GB is the max supported RAM for that OS, anyways. Not really a problem on Windows 10, anymore. Home supports 128GB or something and Pro supports 2TB. But, yeah, I've always preferred 4x sticks despite the warnings out there of it being too stressful on memory controllers. I never had any issues. I don't overclock RAM. Anyone that's OC'd for enough years has to come to the conclusion that OC'ing RAM will corrupt your OS at some point. I just buy what I need/want.

If you want to get even more detailed, you need to look at the topology of the ram slots on the motherboard. If it is Daisy Chain, then 2 DIMS of dual rank ram will hit the fastest speeds (in the correct dimm slots). If it is a T-Topology, then having 4 single rank dimms or 2 dual rank dims will be about the same performance and reach about the same speeds (other than lower memory dimms can achieve higher frequencies easier).

[@bloodbathory5624]

Hi Sir, i was looking into RAM and motherboards and while i read that most motherboards have a daisy chain RAM topology, i was looking at 16x2 Gb RAM kits at 3200mhz and 3600mhz for ryzen cpu since i aim for 32gb and 2 dual ranked modules are best for daisy chain RAM topology. But the problem is i could only find kits at cl16 for 3200mhz and cl18 for 3600mhz and not cl14 or cl16 respectively which is considered to be kind of the sweet spot though more expensive. While on 4x8 kits i could find the desirable cl14 at 3200mhz or cl16 at 3600mhz. Does that mean i should search for a T topology motherboard and use a 4x8 kit to get the best of both worlds? I was looking on the b550 motherboards and btw i did manage to find a hyper x fury 16 gb single module at cl17 and 3600mhz but i cannot be sure if it is dual ranked but most of them are so i guess it will be as well, its the (HX436C17FB3A/16).

Ranks are always per channel. Counting them together over channels is confusing because computers have different channel configurations(2-8). Also if you have 2 SR sticks, one stick in one channel makes it single rank. Install them into one channel(incorrectly) and you get dual rank but other channel is empty which is bad.

The x570 Tomahawk has a daisy chain ram Topology. This means the fastest RAM speeds you will hit are going to be with 2 dimms of dual rank ram. If you had a T-topology motherboard, you should be able to achieve the same speeds with 2 vs 4 dimms. The topology refers to how the RAM is connected to the CPU daisy chain has 2 slots that are most efficient, and the next two take a performance hit. The T-topology is equidistant for all 4 slots and should have the same speeds with 2 vs 4 dimms. Also, The memory controllers get over saturated when you have more that 4 ranks of ram so there could be some latency issues I haven't been able to find solid benchmarks exploring this though.

No.. Some RAM sticks are Single Rank and others are Dual Rank.

[@jose7tech572]

love to learn new stuff with u guys

[@miniweeddeerz1820]

this is incorrect. if you put in 4x16gb dual rank sticks you get quad rank on consumer desktops which is faster than dual rank (4x8gb single rank or 2x16gb dual rank). the downside ofc is more ranks more imc stress lower max ram speeds.

[@stevetb7777]

So it is faster but it is slower? Lol. Overall, is it faster.. or slower due rot the lower max memory speed?

[@miniweeddeerz1820]

@@stevetb7777 depends. Let's say a ryzen CPU can run memory at 4500mhz (yes I understand it's way too high over the infinity fabric humour me). And let's say with quad rank it can only run 3933mhz. Well that's okay because the memory on ryzen should only go up to 3800mhz so you get the benefits of quad rank, the fastest rank config on consumer desktops, and the highest 'good' speed for ryzen. On intel however you can normally outclock the benefits of quad rank so normally dual rank of higher speed is the best config. Obviously the board and bios also plays a large factor in what clock speeds you can achieve with quad rank.

@@miniweeddeerz1820 Good answer, thanks. I myself am looking at 2x64gb. I'm looking at a CL18 4000mhz kit that is the same price as the CL16 3600mhz kit. Do you think I'm better off getting the CL18 4000mhz kit, doesn't that mean it is probably better binned? Thanks!

@@stevetb7777 wait can you link me them? I'm not going to buy them im just flabbergasted that 2x64gb sticks exist. Largest I know of is 32gb modules. Also I guess timings are nice to see. Btw are you using a dual slot board? If not is there any particular reason why you want to only populate 2/4 slots of a 4 slot board? I am assuming you are using a consumer motherboard, not like a threadripper or something, with a consumer specific recommended rank cap as well, which if you arent why only 2x64gb instead of 4x64 or maybe even 8x idk. Also if you put in more than 128gbs of ram, you'll go over quad rank per channel and it may not work, or you may get performance deficits. Many boards have a official ram cap of 128gb because of this. Also why do you need 128gb of ram? And for first impressions, I would probably take the 4000 cl18.

[@mikeramos91]

If you’re upgrading ram and you’re motherboard is only dual channel supported, would it be better to have 2 sticks or 4 sticks or it doesn’t matter?

[@elliotmcconnell5449]

What kind of performance difference does this make? Does it help lighten the load of the cpu when fetching data?

[@Dexx1s]

It's a difference you'll never notice in anything other than benchmarks. The CPU wouldn't be affected. The CPU simply requests data and then waits for that data. Other things like the memory controller handles actually getting it from the RAM sticks, or storage, if it's not in memory and gives it to the CPU.

[@tst6735]

What about 4x16GB = quad rank?

[@teddyoflove5897]

Thanks. When I found recent popular video about this I was under impression that my Trident Z rgb 2x16 is not giving me full speed and was considering swapping it out for 4x8gb kit. Your explanation is far more easier to understand. I checked and my sticks are dual rank, so I am already getting full speed. Only thing I still did not understand what would happen if I add 2more sticks of same ram? It would run slower ?

Thanks for the useful info, as always! I assume that you are answering to this because of GN's recent video about ram and the zen3. So if a full kit of single rank ram gives such an important boost to Ryzen, how can I benefit from that on an ITX board with 2 dimm slots? I currently run 2X8GB G.Skill Trident Z Neo C14 (single rank). Would I benefit if I swapped them out with 2X16GB sticks?

[@bogodoyandex9654]

that why 16gb dual rank ram are expensive than 2x8gb single rank ram. when you found that 16gb ram are cheaper than 2x8gb ram at same seller,No doubt it must be single rank 16gb ram ,but they won't tell you. example : 3200mhz hyper fury 8gb single rank ram about 50 dollar.3200myz hyper fury 16gb dual rank ram about 110 dollar. when you found they sell it at about 95 dollar same brand ,same 3200mhz, it must be single rank.

[@Heliocentric]

Currently most 16gb ddr4 modules are single rank unless its high performance memory.

[@gametime2473]

It wasn't clear for me, are you saying that 4 dual rank RAM sticks isn't faster than 2 on a FOUR channel RAM computer? Or was this just for a dual channel RAM motherboard?

Nice, I am upgrading right now !

[@onimaruvt]

so what if i have 2 duel ranks and 2 singled ranks mmmm

[@PhillipLemmon]

So basically just do what you been doing and use 2 sticks. Thanks got it Luv ya Now if you want to populate the other 2 ram slots thst are empty... You can look for the ram that has "dummy" sticks that have RGB in them.. gives the illusion that you got 4 sticks..... And it looks REALLY Kool! Just a thought hope this helps you! HAPPY MERRY HOLIDAYS!!!

[@xboxbenny]

Yes and this is why you don’t need 32GB even in new systems. A 4x4 of single rank DIMMs will perform as well as 4x8 ones, given that you aren’t maxing put your 16GB (something I’ve never done). I just installed 4 identical 8GB ram sticks in my Ryzen and it’s running perfectly now, literally night and day faster than before with just 2 of the identical sticks.

[@daemonthorn5888]

They may "perform" just as well, but 32gb of RAM is still 32gb of RAM. Saying that the 4x4gb "perform just as well", so you don't need 32gb, is misleading. When they say the performance is the same they are talking about the RAM's speeds. Not it's capacity. 32gb is still double the amount of RAM as 16gb. So if you need 32gb, you will still need 32gb. Saying, "you don’t need 32GB even in new systems" because "4x4 of single rank DIMMs will perform as well as 4x8 ones", is very misleading. That 4x4 of single rank DIMMs is still only 16gb of RAM.

[@futureofboxing6025]

Yeah tell beamNG drive that and watch your computer crash 😂😂

So it would be better to do 2 sticks of 32gb DDR5 than 4 sticks of 16gb DDR5

Is it better to get 4x16 or 2x32? Also, for AMD CPU is Corsair Dominator Platinum DDR5 or the G.Skill Trident Z5 the best choice?

Is one dual rank DIMM the same as having 2 single rank DIMM in dual channel? Or does it only apply to dual channel vs quad channel.

[@tomchandler7568]

A dual-rank DIMM is similar to having two single-rank DIMMs on the same module

@@tomchandler7568 this is right, but i think that do not answer the question. I think dual channel is not the same as dual rank. I would say, dual rank ram in dual channel mode are more faster. But i‘m not sure. Would be nice to know.

No it’s not dual channel you need two sticks for dual channel it just means your stick acts like two sticks in the same channel so it’s single channel but 2 sticks

Shouldn't four dual-rank modules mean 8 ranks? That, in theory, should allow eight rows to be open at the same time, which might decrease latency in getting to different addresses.

4 is the max so going 8 will only stress and do nothing

Four dual rank DIMMs can negatively affect your system performance in game and system stability, especially on ryzen.

[@hrayz]

I run 4x16GB all dual ranked sticks. On my older Ryzen 1700X or 2700X, I never got them to their full 3200 MHz (best was 2933 with the 1700X, and 3133 with the 2700X) even if I only ran 2x16. My new 3900X runs the same memory on the same board (Crosshair Hero 6) at 3200 MHz no problem, even 3233 MHz worked perfectly. It's mostly the internal ram controller on Ryzen that will make things work or not.

[@Entity8473]

@@hrayzI had a different experience. With 2x16GB dual rank HyperX Intel only certified XMP 3200 DIMMs on my 2700X. They worked like a charm despite not making on MSI's certified RAM list. Upgrade to 4x16GB single rank modules and had to increase SOC voltage to 1.175V to get 3200 speed stable. Just goes to show motherboard and CPU combinations with Ryzen really matter. Anyway when I said 4x dual rank may affect performance, I meant it reduces your frame rate in some games for who that matters to even though most peoples would never notice unless playing with a GTX 900 series or something older.

[@mathspodethemighty3484]

so having 4x8 single rank is equal to 2x16 dual rank, and having 4x16 dual rank doesnt give more performance and only capacity is that right ?

[@phdsouza8017]

Hi from Brazil, Tech! I saw that you used 32GB dual-rank per channel. Does quad-rank per channel even exist for desktops? Could you please make a video (maybe just a common live-talking clip) about dual-rank vs quad-rank memory per channel? I know it's off-topic for most people but, since you suggest 64GB sometimes, I wonder if it would end up being quad-rank per channel. Would quad-rank reduce memory frequency (in a relevant way, maybe for intel since ryzen is capped by fclk)? Decrease gaming/editing performance? Affect CAS latency? Different behavior from Intel and AMD? Would 2x32 be better than 4x16?

[@heydeonhere]

Dual rank dimms 2x16gb will have a lower cl like 14 for example.
