Videos like these are WHY I watch this channel. "Screw it, lets see if it works" is basically the origin of scientific practice. This is the kind of argument tech nerds have been having for years, and most people don't have the hardware stash to actually test this kind of thing out properly. I love this kind of "lets find out together" approach, and appreciate that the "well that isn't how that was supposed to work" moments don't end up cut out and only in some private bloopers group chat or something.

early on it mostly had to do with XMP and some of the settings in it that don't work with AMD's memory controller(that's changed over the years since first gen Ryzen released). the interesting thing is that if you manually set all the XMP timings they'll work fine, enable XMP and sometimes they don't work.. the other thing is that running 1.38v instead of 1.35v seems to solve most of the memory compatibility issues especially if you're using hynix memory modules.

[@thedoofguy5707]

That video can be summed up with a quote from Christopher Titus: "I don't fail, I succeed at finding what doesn't work." And to be honest, it answered a lot of questions I had about RAM speeds and timings, so it's definitely not a waste. It was educational, it was entertaining, it was JTC.

As a car guy - this explanation ( from Crucial's FAQ) was what made it click for me: "If we think of memory as a race car, the module speed (MH/z) would be like the raw horse power of the engine, and the timings would be the driver of the car. As the driver of the car gets better at handling turns and responding to obstacles on the race course, the car will perform faster, so much so, that you can have a car with lower horsepower outperform one with more horsepower, if the driver (timings) are faster in the lower horsepower car than the car with more horsepower." What an awesome video. I love that Jay keep's his hubris in check such that he not only will say "frick" it and try something like this, but also not try to hide when his initial hypothesis/notions are off the mark. It would be quite easy to shoot this video, scrap it, and re-shoot with the narrative that he's an infallible tech guru. I love you for that Jay.

It'll be tricky to get /boot and /root to install on OpenZFS, but certainly possible and stable (apart from a bug regarding hibernation).

[@johnscaramis2515]

14:45 quite easy to explain: the IMCs act smart and use dual channel for the first 8GB and go to single channel, if they have to use above 16GB. So as long as your RAM requirements stay within the limit of the chnalle with less RAM * 2, you get dual channel bandwidth. If you need more RAM, above the dual channel limit, your scores will decrease. So it's no wonder that you see the same score in CB. Not sure what amount CB requires, but if you fill up the memory, so that CB is forced to access the single channel area, you will see a decrease in performance. However: Even that decrease is better than swapping to HD or SSD.

Cinebench is not a good benchmark for memory, it mostly uses CPU cache. Also 4 stick combinations will (most of the time) have the benefit of running dual rank while 2 stick usually run single rank.

[@Sp4rKzTV]

@@mmmdawe Yes/No. A lot of testing has been done on this. There's also contradicting information online as well. But basically from testing (I personally did with my current computer) and research I did on the topic and looking at other channels who tested different scenario and configuration (Like GamersNexus and ActuallyHardcoreOverclocking) I think we can conclude that : - At same timing and frequency (so let's say 3600Mhz CL16), Dual Rank is better than single rank (note that Memory rank =/= channel, those are 2 different things). - However, single rank will usually allow you to get better timing and higher frequency than dual rank. So at a certain point it MIGHT, be better. But we're usually looking at really high frequency (like above 4000Mhz). Since most people don't buy crazy high frequency RAM (most people will shop between 3200Mhz - 3800Mhz. In that range it's possible to get pretty good timing on dual rank (getting single rank RAM that does better is going to be very expensive) so dual rank will usually perform a bit better. The difference is NOT that significant however and I wouldn't worry too much about it. We're talking a few percents in synthetic benchmark.

You’re going to have to test higher speeds with mismatched timings as well as mismatched capacities for the heck of it. It would also be interesting to see how a matched set of 4 sticks would compare to a mismatched set of 4 where the lowest stick is a stick of the matched set.

Super interesting video. There are two more questions/tests I would be interested to know the answers to - 1) how would the two fastest matched sticks compare in the overall results. 2) Does having the mismatch in sticks introduces some memory instability if pushed to the limit by memtest or similar tool.

I had 2 sticks of 8gig 3200 Gskills already in the rig and it ran fine for over a year. A year or so later I attempted to add in an additional 2 sticks of 3200 Ballistics I found a good deal on at the time to double my ram. The system did not like it, and would drop the ram speed to 1800mhz, and any attempts to clock them back lead to the a boot loop until the system set the ram back to 1800 mhz. I eventually got 4 sticks of Ballistic and took the Gskills to another AMD rig that they work fine in. Having had mixed ram stick builds in the past that function perfectly fine, lesson learned is that not all ram likes each other.

[@sirmonkey1985]

depends on the system setup whether it's AMD or Intel since there is a slight performance increase running 3600 over 3000 that may offset the performance loss due to timing and what the systems being used for.. it's likely that overall there's no significant benefit to running 64x3600 vs 64x3000 but saving a couple 100 dollars might be worth it.

Hah! Love this. Excellent video. Gotta say though, with modern day mem controllers, you will still start seeing performance losses on larger capacity setups. Ram virtualization makes a lot of these mismatched setups not only possible, but even perform decently. It might make boot times a bit slower, but I'm not even sure you'd see a human measurable difference. Capacity will create a difference though. If you go from 16 gig to 32 gig, no big deal. From 4x8 sticks at cl16 to 4x16 sticks at cl16, you'll start seeing a lot more heat from the memory controller. At 4x32 @cl16, if you can get it to boot without lowering timings, your memory controller will absolutely hate you. Obviously this is with a standard dual channel currently Ryzen or Intel Z490 chipset. Server applications and higher dim/channel capacities will see the same type of response though.

Lost performance isn’t typically the concern with mismatched RAM, rather the errors that can occur to cause crashes. That’s the main reason matched RAM is greatly important in servers, as they need the utmost amount of uptime and data loss is a great concern.

[@dermothoyne2393]

If not mistaken Jay, the mainboard will maintain dual channel memory, up to what memory matches up [off the cuff or manually tuning]. Any excess memory gets backpedaled to single channel Having that 24GB visible, only 16GB would be handled dual channel, where the excess [in this case, the other dimm] be running single

I have a Ryzen 9 5900X, TUF 6800XT, and 32Gb Corsair Rgb Pro 3600Mhz CL18 (four sticks), tightened the timings to CL17 at 3600Mhz and also tried CL16 at 3200Mhz, was virtually no difference. If you have 3000Mhz CL18 or something like that, you will not get a major uplift even if you get 3600Mhz CL16..keyword being major..small uplift yes, but i would rather have overclocked the ram you have to the best speed and timings it will do and settle for that.

Another curve ball to the conversation would be: How would all this testing turn out if you'd take into account that Ryzen benefits hugely from 4 sticks instead of 2.

[@Dr.Spatula]

Really? Last thing I saw was ryzen benefited from single channel

[@malphadour]

@@Dr.Spatula This is totally down to what you are doing with your ram (and what ram you have used). For overclocking then single channel is generally better, especially if you are using a daisy chain motherboard (which most X570 and B550 boards are). For raw bandwidth then dual channel is better because this will guarantee you are running in dual rank. This can leverage about 10% more performance in certain workloads, but is is generally a lot harder to overclock 4 sticks of ram than it is 2. This can of course vary from board to board and ram kit to ram kit. You can of course also get dual rank sticks of ram (16gb micron Rev E for example) and in this scenario you can have best of both worlds with dual rank and also potentially better overclocking. (Edited - sorry Dr Spatula that was very confusing)

I slapped another 4MB out of the shelf, and then spent years upgrading it. It ended with 384MB and Windows XP, still running smoothly after I REPASTED it, the thermal paste had crumbled to dust. From 4 to 384. Nothing else had such a upgrade in the history of anything, ever. Imagine a MOPED with 4HP. You upgrade it until it has 384HP and can rip burnouts at 100mph.

[@LauRoman]

so i have a living room pc with 18 gb of ram. It had 2x4gb sticks of ddr3. Some time later i added one 8gb stick and moved the 4gb pair onto a single channel. sometime after that i put in a 2gb stick on the remaining slot to see if it works, because it misbehaved on another machine but seemed to worked just fine and i kinda was too lazy to take it out. Oh, and that 2gb one is a sodimm with an adapter. If you ever want to use laptop memory on PCs with an adapter, make sure it is not low voltage (ddr3L), and some chipsets seem to be iffy on rank configuration. And my nephew's machine that i built for him has 12gb of mismatched dual channel ddr3 with two sodimms + adapters (4gb and 2gb). Don't judge me, it's what i had available at the time. When i get rid of the living room machine, the best memory will go into his pc (if he doesn't get bored of pc gaming and i can't afford to build him something ddr4)

What's really happening with mixed RAM is if you have mixed capacity, when you exceed capacity of the less capable kit you go into single channel.

Jay is not the guy to go to for proper scientific stuff like this. The video, whilst entertaining, is a shambles from a testing perspective. Steve would pull him to pieces on his methodology :) And you are absolutely right - and using Cinebench was utterly pointless.

[@FHL-Devils]

I ran 48Gb in my previous build with no issues (64 on my current)... 2x16, 2x8. Had a 44Gb flex-capacity RAMDisk on it (I use a ramdisk for torrents before they auto-transfer to my NAS). Also, of course, my Temp folder, and lastly I run my browser caches off the randisk (which is freakin' sweet). It can be hell to set up something so customized, and there can be quirks (like MSI installers that are too dumb to recognize them), but for pure performance and keeping the system clean, it's the single greatest tool you can have in your arsenal. Jay - maybe a video on RAMDisk would be a good topic?

[@MrMurdock86]

For real, though, my rig is running the same ‘model’ (XPG Spectrux D41) ram all around with the same timings, but with channel A packing 16 gig sticks, and B with 8 gig sticks. Funny enough, each using a different controller in the pair. I might actually try tweaking the timings and slowing the xmp clock after work just to see if it’ll boot and run tighter

[@therealpbristow]

OK, Right now I'm running 2 pairs of 4GB DDR3 on an 8 year old ASRock motherboard. I got here gradullay, strating with 2 piars of "GN sticks a long time ago, and at one pound replacing a pair with two mis-matched 4GB sticks. The first lesson I learned: - Forget XMP! It would usually either not boot at all, or just give me unimpressive performance. I triedtweaking voltages, clocks peeds, timings, everything, but in the end, whatever crazy mix of memory I tried, I found my optimum timings to always be as follows: Slightly down-clock the memory from the standard 800MHz (DDR1600) to 777MHz (DDR 1555); Timings: 10-10-27-37. This is basically JEDEC #5 timing, according to CPU-Z. Not only is this optimal, it's also very close to the "safe" configuration the motherboard defaults to whenever it thinks the previous boot session failed due to bad overclocking (in most cases the untidy shutdown is actually due to a power failure, but try teaching *your* BIOS to tell the difference! =:o\ ) - So if I'm forced to run for a while in the "safe" config I don't get any nasty surprises, other than (ironically) increased fan noise from the crappy old cooler I've been using! So even though the ASRock motherboard was billed as an overclockable board, in practice I have never got any advantage from trying to overclock my memory over "almost but not quite standard" DDR1600; Whether that's because the board is crap or my memory is crap, or because memory controllers got cleverer than human over-clockers a long time ago, I don't know. And while I still try to buy my memory sticks in matching pairs, I no longer worry about it if a single stick of high capacity is going at a low price, and actually *works*.

[@lCountMike]

I have an issue with XMP being called Overclock, it is what articular RAM is designed to work at and is certified by manufacturer as best tested frequency. Manual settings over XMP can only be OC of RAM itself. However, it may cause IMC to be overclocked in case CPU's "natural" IMC frequency is lower than what XMP dictates but that's overclocking IMC and nor RAM.

[@СергейДенисов-и3ы]

The uplift in memory volume compensates the drop in speed rates, but the drop and uplift sizes are different (uplift is bigger), so the 3dmark scores seem to go higher than initial setup, as the memory capacity overhauls the speed drop significantly.

I will rip everything out, do a deep clean of case and parts and then try it out and see temps before doing any changes to setup (and even changing thermal paste, for my own curiosity sake).
