Beware before buying memory for 12th Gen Intel

forget everything i've ever told you about ram today we're going to talk about the difficulties of ddr5 specifically with intel 12gen because it's the only ddr5 system out so far our platform yeah

limited time giveaway click the link in the description below [Music] i probably have the world's supply of ddr5 right here uh okay so we got a bunch of different ram sticks here before we get into some of the testing here i want to explain to you why it's it's so difficult this time around for uh turning on xmp and then just having a boot in the past when new ram comes out ddr3 ddr4 ddr2 even but ddr3 ddr4 4 specifically that base ram speed we've talked about how ddr4 is 2133 remember ddr3 is what uh 1333 i believe it is somewhere around there it takes time for the ram manufacturing to mature to get faster and faster ram speeds but this time around we went right from the base 4 000 up to 6 000. and xmp is an overclock it is an overclock of the cpu's memory controller to be able to handle ram that's that fast but because of the fact that everything is doubled in term in terms of capacity the faster the ram and the higher the capacity the even harder the even harder that even is on the ram controller or the memory controller so there's a this is one of those instances where if you watched a video of mine or any video of mine where i preached turn on xmp you're paying for the ram speeds and you're not getting it um you may fi you may notice that your system is boot looping and it goes into a boot loop hell because of the fact that it just simply won't post that way and it's even more convoluted by the fact that you might have see these are 5200 megahertz dims right here from corsair um most rams started at about 4 800 megahertz and up we didn't really see too many 4 000 megahertz dimms which again is the base speed for ddr5 we saw brands going right into the high ram the high speeds so it's gonna it takes time for bios to be updated to support faster ram it takes time for the you know the ram to become validated on different motherboards motherboards also play a role in this and the higher capacity is just it puts a lot of strain on the controllers well like i said you might find six thousand megahertz will boot with two sticks installed but not four and vice versa and then there's the combining of dual ram kits just because you have four dimm slots and there's gonna be a little bit of basic knowledge in here for those that might be new to this this is not an all-inclusive understanding timings or channels and all that stuff i'm just giving you a little bit of basic knowledge just because you have four dim slots on your motherboard does not mean it's a four channel ram it just means it's two channels per or two two dimms per channel so you could double the capacity per channel so if you find a motherboard that only has two slots like the one that we put in kia pspc that's a dedicated overclocking motherboard which is designed to only have one stick per channel because of the ultimate stability you find with single dimm per channel now what a lot of people do myself included is instead of buying quad channel kit which was something that you really only used on either thread ripper for amd or xtreme platform for intel which had four channels or quad channels of ram they were designed to work together what we're finding with 12th gen is if you buy two dual channel kits which are the same part number the same timings the same frequency and all that and put them together it won't work it's it's really messed up so there's a lot there's a lot here i want to test and kind of figure out but i want to show you guys just how just how frustrating this can be we're going to be using our 12th gen system here as sort of our test mule now it's important to remember that every motherboard's bios is going to look different this is an msi board which looks very different than asus which also asus looks very different than say asrock which looks different than gigabyte so your mileage may vary on some of these settings and such but what they all will have is over here somewhere an xmp profile now there's only one profile for this particular set of rams sometimes you'll see two um you will find these settings also in overclocking because like i mentioned it is an overclocking um function so this one's just different it says memory xmp so enabled right so that's going to enable our 5200 megahertz which you can see right here and 5200 is not that difficult um it's when you start getting up to like the 6 000 megahertz range which g-skill we have a few of those here these are these are four g-skill 6000 megahertz stem effects there's no leds on them either because uh these have leds at 6 000 but these do not because for whatever reason they don't i don't know how else to explain that one but you can see it posted no problem here this is our origin pc 12th gen build no problem hey there's my red lighting and stuff so what i've done now is i've added a the exact same memory spec in white the only reason i did that so i can keep track of it anyway they're exactly the same this one just has a w in the number because it's white 5200 megahertz same timings exact same part number just with a w at the end of it is it going to boot well we'll see because adding i just turn there we go because adding a second set of ram is where everyone's been having the problem so let's see if it posts it 5200 [Music] it's slowly doing something probably training it right now [Music] stuck on 79. nope [Music] slowest post ever right now one thing i've noticed on 12th gen is if you change anything it's just like ah what okay so it did post but is it at xmp or did it okay memory is changed f1 setup so it just posted right now at 4000 which should be the base because it noticed something was different yeah see there it is right there ddr4 ddr speed 4000. so if i go in here now to xmp profile and click that all i changed is the xmp but the issue has been whether or not uh it's going to it's the best way to put it i don't know how to explain it i have a feeling this one might because 5200 isn't too crazy it's when you start really getting up to the high speeds we've got a red light right now on the motherboard i'm not sure what that is [Music] i think it's also important to keep this all as one clip so they can see in real time the length of time this is taking i mean it's progressing just very slowly we still have a red light on the board which we didn't have a moment ago i think it might have just boot looped a2 nope we got a keyboard we have no video yet oh it's boot looping [Music] see this yeah it's boot looping for sure oh no it just didn't initialize video at the start is it actually running 5200 uh yeah it is okay so this one actually worked pretty well but the why did i undo my colors whatever but let's say you shelled out the money now for six thousand megahertz dim so now i have i'm not sure how many gigabytes of uh i don't know how big these sticks are i really don't they got to be at least 16. there's gotta be at least 64 gigs 6200 megahertz so right now it should identify a ram change which should then mean that it's going to give us that same memory as changed screen okay it is 64 gigs at 6200 so the question now is going to be will it post with xmp the 6200 has definitely been hit or miss [Music] so i'm turning this because you know this is why i love motherboards with qr or q code readouts because you can definitely tell if it's stalled or it's hanging on something if it hangs on a number you can sort of figure out what's going on [Music] oh there's a po those double zeros first time we've seen that and then it went green back to red in a boot in a loop now that's not uncommon because it's training every time it posts like a new configuration it trains it let's do a video someday about memory training and what's actually happening here are we stuck on 31 nope it's moving but you see how this can this can make people think something's wrong how long this is taking this is not a normal blue process usually after it does it once you're fine so we're on our second loop 3c 55 0 0 and it's looping so here's an example of 6200 megahertz ram with a otherwise factory setup we do not have an overclock applied to the cpu at all this is out of the box the only button we've pushed is xmp which is what you would expect to get what you pay for and now it's looping and what's going to happen here is it probably loops a few times and then the bios might eventually figure out like hey something's not right here and then it will just go back to factory fail safety faults and then it will warn you like hey but it's on its fourth loop and there's number five so this is where people tend to freak out especially if they're new and they built their first pc and they saved up they're like you know what i'm gonna go 64 gigs of ram and go fast fast ram right 12th gen intel cpu there's no reason to expect that it wouldn't boot yep okay i think it just went into safe mode after like six boots we got usb d6 this is where it's looking for input device a2 okay we made it past that so here's the thing look it completely bypass our displayport initialization not in bios it's going to probably go right to the desktop if it comes on but the fans also went full speed and i'm glad i kept talking through that so you guys could see the process and how long this has all taken place so far but now i have keyboard i have mouse a1 says we're posted but we have no video see this so this is where newbies would really get frustrated and they would start thinking something's majorly wrong with their system and this is where a cmos clear is necessary because the cmos clear will force it to go back to that base clock i'm just gonna hit reset right now i'm curious as to if it's going to potentially just boot now with whatever its most known settings were if initial ports or reports are correct by removing two sticks of ram it should post that's what people are telling me and that's what the just folks i've been talking to about this problem have said which means the even faster ram at 6200 because i believe those are six thousand um which is why it's a dual dimm kit i'm gonna do a cmos clear for good measure that's flash bios is there no cmos clear button on the back of this motherboard msi what year is this yeah charge five six hundred bucks for a board it better have a clear cmos button i didn't push anything why did it turn on it just turned itself on i'm gonna figure out how to clear the cmos on this i'm not turning it on it's turning itself on i'm gonna turn that off i'm gonna take out two sticks okay it booted so now we should be able to just get into bios i think what's important to show though is the fact that i did not clear the cmos i didn't because i didn't know how to do it and it kept turning itself on ironically and then by removing two sticks now we're into windows okay enabling xmp uh oh wait speed4800 yeah it booted at 4800 which is not what i told it to do how weird is that 4800 is a weird arbitrary number because 4000 is where it was on that first boot when i just let it do its own thing fine whatever save and exit yes will it post 6 000 megahertz with two sticks of ram i know i've gone on so many tangents and stopped talking mid-sentence on trains of thought but you guys are seeing this in real time that's why i like doing these types of videos rather than being super edited and polished because you can see the frustration in real time because i think this might actually make people realize oh that's what i was saying all i did was force a change with the memory by taking two sticks out that forced it to retrain and retry and then it worked but i think it's going to boot loop again yep there it goes nope yep nope oh yeah it's doing that thing we're half posted where we don't have a video right now but it might pop up in the desktop because why wait nope never mind rebooting just kidding i like how even the pump okay there we go the pump was like nope it did go so do you see the importance of not cutting these because it's like poop but are we at 6200 or 6000 i mean six thousand the only difference is i took two sticks out so there's your there's your example too on capacity affects compatibility stability but it's something that has been it's always been the case it's just i i don't think ram at even ddr4 levels was getting fast enough for that to really be a problem the first time i had a legit turning on xmp was a no-go post period was the crucial ballistix max 5200 megahertz ddr4 dimms that i have i have no led bars on them that absolutely positively refused to post on my intel 10th gen 10 900k at anything above 4 000 megahertz anything above 4 000 was a no-go now that nothing imagine that you paid 900 per two sticks and i had four of them in there eighteen hundred dollars worth of ram yeah it was the fastest ram in the world at the time and we were using we were attempting to use it for our overclocking competition stuff when we were doing with steve and ram was absolutely affecting our score and we knew that time tight timings and fast ram was absolutely bringing up our score imagine paying for 5200 dimms at 900 per you know two sticks or 450 dollars a stick and then not being able to use 1200 megahertz of it and then 11th gen camera alarm 11 i came around 11th gen 1100k booted 5200 every time so you can see why i'm saying 12th gen out of the box the ram speeds being as fast as they are absolutely not letting it post now i have pretty good confidence here that the 6200 dim sticks would boot without a problem because 6000 just did but you know i have to put my money where my mouth is now where my mouth from my money is or whatever and uh test it okay so this is the 6200 megahertz ram i almost feel like as time goes on you see it all the time with new motherboards the first few bios iterations three four or five bios iterations will say improved memory support and it's because of these exact problems you know what's 22 is if you want to if your system is being stupid and you actually want to force it to do this you don't have to take out you can take out one stick of ram or just swap them because each ram has an id and when you move it it forces this to happen too there we go and 6200 megahertz so yeah two sticks you're good you're good you're golden which sort of sucks because with so many motherboards coming with four sticks around i feel like people's natural inclination is gonna be to fill it up i wanna see now exactly where we no longer post with the four sticks this is why i have also scrapped remember i said my personal build which by the way just waiting on the cables they're coming from australia you can understand what shipping is like just be patient i am that's why i scrapped the idea of going 128 gigs of ram just for lulls because i will never touch a fraction of it and just going with two sticks because as you can see i'm not going to be able to get the xmp out of it so i'm not going to show you guys me testing over and over and over the different speeds but what i'm going to show you here is if you want to do this for yourself the logic enable your xmp profile that way your timings and your voltage tighten up a little bit now i'm going to go down here to the memory where the memory speed is so you don't want to reboot after you enable it yeah do not do not reboot after xmp because obviously it won't post we've already showed that with this particular setup so i'm going into memory here and then i want to change the frequency i know 6000 is not going to boot and i know 4000 will so i'm going to start somewhere in the middle i'm going to start like 5000. i'm going to see if 5000 megahertz will boot and i'm just going to do this until where i find it doesn't and then i'll go back and then what you have to do technically is run some memory intensive tasks whether it be some sort of mem test or a utility or just your editing apps and stuff and test for stability there because it might boot it might post it might go online but you then might start getting weird blue screen errors as the if the memory controller's around the edge of its stability um we'll just do this one take right now to see if it boots and then i'll come back and show you where it finally decided it wasn't going to go anymore i have a feeling 5000 will go just fine unless it's just straight up a 4 channel anything above base problem which i'm not i'm not completely convinced that's not the case that's not a downward point there we go that was bugging me okay it just boot looped i you know what i don't even feel like inclined on telling you guys where it finally boots if it can't even do 5000 at the voltage it's set so there you go i've had a lot of requests lately for me to do a video about ddr5 and speed and compatibility and ram stick count and stuff because people have been experiencing all kinds of problems i feel bad for one guy on twitter that told me he just ordered all his parts and he ordered like fast four sticks of ram [Music] maybe get your money back for two of them so a little bit of advice then at least at this point for buying advice is gonna be if you need the capacity just buy something close to base and then that way you're not overpaying for speed that obviously you can't use uh if if you absolutely need the capacity if you want the speed if ram speed is important to you like gaming ram speed is fairly important then any dual channel kit just about should work like i showed you guys because i showed you a 6200 megahertz kit that is that booted with two sticks just fine i showed you how 6000 won't boot with four sticks so and now it won't boot at five thousand and it probably wouldn't boot at 4800 either because reasons but so that would be my advice if you need the capacity get the lowest speed ram kit that you can unless you want to bet you know wager against future compatibility allow you to turn it up later you might be paying for performance you're never going to get um and then speed two sticks you're fine whether it be 32 gig sticks or 16 gig sticks it's not the first time we've seen this it's just the soonest i've seen this because of how fast ram launched and went with ddr5 so as this thing continue continues to boot loop why don't you continue to subscribe if you're new around here and maybe check out some of our older videos thanks for watching guys and we'll see in the next
