a Seuss grew impatient waiting for Samsung's reached volume production on its 32 gigabyte ddr4 you dibs and so the company instead designed a new double capacity dim standard this isn't a JEDEC standard but it is a standard that has gotten some attention from Zadok and from g.skill both of whom have made some of the tallest memory modules the world has ever seen these DIMMs are 32 gigabytes per stick so 2 of them would give us 64 gigabytes at 3200 megahertz and after an overclocking average some pretty good timings 2 of these sticks would cost you about $1,000 with the 36 hundred megahertz options at around $1,300 today we'll be looking into when they can be used and how well they can overclock before that this video is brought to you by coarser and it's void Pro headset the void Pro headset is available in wired or Wireless versions with the wireless option supporting a boosted range upwards of 30 to 40 feet the headset has full RGB LEDs on the ear AQAP's has 50 millimeter headphone drivers and lasts up to 16 hours on battery it can also be plugged in for Wired at use and is now lower in price than when it first launched a noise cancelling microphone is also included along with an easy mute indicated by an LED and you can learn more at the link in the description below as for what it is this is a double capacity dim it's not an official standard it's an Asus designed standard and only two memory manufacturers presently supported so this stick about $500 for just this one but it's 32 gigabytes so that's a lot 16 gigabytes per side it's difficult to do this it has to be done by making the PCB taller which obviously creates all kinds of clearance concerns also a lot of signal integrity concerns turns out it's not so easy to just add more and more memory to a chip or to a PCB because at some point you have trace length issues you have signal integrity issues and also you have issues with motherboards supporting it at all in fact we don't even quite understand how this works because Asus and Zadok aren't presently disclosing the deeper details on it as it presumably Asus thinks it gives them a competitive advantage although the market for this is so small that they might as well really just is everything because no one's buying them anyway but there might be some very very specific use cases for this and we'll tell you why as we go through but either way this is not an easy thing to make and it does allow you to theoretically max out the memory controller on the cpu intel has validated the 9900 Kay it's work without and 28 gigabytes of memory the challenge is getting that much memory in four slots and these only work presently in motherboards with two slots so that's where we get some hints as to what's going on the other downside is that it's presently an Asus designed memory spec which nearly guarantee is limited adoption issues itself only has three motherboards that presently support the DC dims we tried using them with our Maximus 11 hero with four slots for standardized benchmarking but found that it won't even boots only the Z 390 I at Mini ITX gaming board the gene and the apex which is the one we used support DC memory the Z 390 IB and Mini ITX is one of the more meaningful use cases of populating two slots with higher capacity dims than would otherwise be possible the apex and gene are also limited to only two slots two slot one DPC designs can be useful for extreme overclocking by simplifying the memory traces and allowing higher overclock on the memory when it's closer to the CPU but we don't commonly see extreme overclocking overlapping with high or ultra-high memory capacities in fact in a lot of xoc instances max mem is set in Windows to get better timings this is already an extremely limited use case then it's $800 starting for the lowest frequency of the dims by is a DAC and G schools around the same starting price so if you're using a motherboard with four slots one you can't use these so rule that out too you could get 64 gigabytes of memory which is what this is for a thousand bucks at 3200 megahertz for in the range of 400 to 600 80 dollars depending on the timings you go for and the memory market so let's call it 500 it's about half the price of these DC modules which is obviously going to really restrict the market for these because if you really need memory capacity main stream platform for some reason because that's all these work on they don't work on X 299 then you might as well buy four sticks 64 gigabytes for half the price but there is one restriction to that which is if you really really want to use the gene the apex or more reasonably you want a mini ITX built maybe you're doing a mini ITX rendering system of some kind maybe a blender system whatever that you take for travel and you really need 64 gigabytes of memory there's a use case there will concede there's a use case there it's it's a very small one but it exists technically so for sake of pure capacity you would be better off going with a board that has more slots and just buying cheaper memory but in theory if at some point this could be done and it won't be any time soon but if this could be done in a way that you have DC dims in more than two slots then okay now we can talk more about where these are useful unfortunately the way these work as far as we know is one stick detects as two sticks so that's going to limit that possibility of going with four sticks using the memory on the apex we noticed in hardware info reports that there are four sticks populating the board but I said earlier the board itself only has two slots available there's some trickery going on here to spoof the memory into working in this board and part of that is done by telling it that each module is two sticks worth of memory we're not quite sure exactly what's happening here and it's not being disclosed presently taking the memory apart wasn't difficult but not particularly easy either there are only a few screws holding each does a DAC module together but the thermal pads are more of a thermal adhesive they're really stuck on there and removing them requires some finesse to not rip off the memory modules underneath we see two rows of Samsung memory across a couple of columns one set on each side this is Samsung's k4a eight g0h 5wb - B CPB memory solution which is an eight gigabit module there eight bits in a byte so we end up with 16 gigabytes of memory per side on these sticks we ran a few tests on a 99 hundred K at Jeff's 4.9 gigahertz all core our tests were focused entirely on determining where the memory gains could be seen when overclocking these were mostly with times by extreme physics as the software is extremely responsive to memory latency and timing changes this is something we've seen in our overclocking streams firsthand where a single timing can change the results by hundreds of points of scoring greases we also ran some Cinebench tests although the software doesn't care about timings and so it doesn't really scale and we did some tasks with maximum which we'll put in the article in the description below this table on the screen shows some of our tuning steps our end results had us at 34 66 megahertz up from 3200 with 1.5 volts T RFC at 300 then 274 T RFC to 256 40rc TR f c3 we tried to lower the TRF see settings further but we ended up with lower performance and eventually blue screens or instability we dropped T fr for for active window 222 for now with primary timing stable at 14 14 14 34 we maxed out TR efi for better performance in 3dmark and we set raster ass delays to for cke to 6 and tuned some of the tertiary timings manually but leftmost alone here's a chart for some visualization of those results our results with XMP only had us at about 49 20 to 49 30 points for TSE physics with a 34 66 megahertz overclock and no other changes to timings Landing us at 51 38 points all the steps in between are also on this chart as you can see in the middle clump of the results but the final results had us at 54 89 to 50 508 points a climb of about 12% in total CPU score these chips actually overclocked pretty well they're not extreme overclocking memory modules so if that's what you want you should still buy something else but they do overclock really not that bad for something that's so capacity focused so that was nice to see let's I guess talk through the conclusions here overclocking is not bad I guess that's something it only works on three boards at present apex gene and then z3 90i gaming which is the more interesting you case because at two slots you can actually kind of start to argue this this scenario where you're occupying the only two slots on the board with the maximum amount of memory possible until the higher density memory modules become available to mass-market so that's really the use case it's super portable mini ITX rendering machine where you just you're having trouble getting high density dims because they don't exist or something and you have to go with this and then you also of course have to build around this because it's gigantic and so CLC is probably the best choice in that instance as well just to make sure everything fits together these let us get closer to maxing out the memory controller on the isie 390 main stream desktop CPUs which intel has validated up to 128 gigabytes on the 9900 K so that's kind of cool the X 299 dark would be an interesting scenario for this as well these don't work in it unfortunately but the reason that would be interesting is because it's 4 slots and the platform supports 8 so if you could get four of these in there you have a super high end overclocking board plus really high capacity and those are things that are kind of rare to put together so that's sort of it doesn't work so it doesn't work speculating about how fun it would be but that would be a scenario as well these are roughly 1.5 X the power consumption of a normal dim of a normal stick but not a big deal really at the end of the day and they are very very small use cases they are extremely expensive and basically an interesting project with limited use cases so most people in our audience shouldn't buy this but there's probably a few people out there a few of you who are excited about this and if you are one of them please post a comment below and let everyone know what you would like to do with these we would imagine the most common use case would be a z3 90i gaming a mini ITX build something focused on very system memory intensive type of processing but you have to travel with it and that's why it's mini ITX otherwise you might as well just Big D go with a bigger Desktop and then more memory modules so that's kind of where we see the use case for this but overclocking is good so job well done Samsung and Zadok on that the heat sinks are more than sufficient you really don't need to worry about thermals on memory for the most part all of these get a bit warmer than normally and it's expensive so that's all for this one kind of an interesting thing to play with but that's about where it ends
