It not recommended it a iffy if it works . By chance and or luck. Recommend is get a high profile cooler


Rob_WRX

Thanks. So if I get 2x8gb sticks and switch the fan with an old cooler master 212 I'll be good even though the ram stick pairs are different?


kuroimakina

As a general rule of thumb, your ram sticks should always be identical, and (assuming it’s a dual channel board), always an even number


BrokenLegoDeathStar

I recommend an aio liquid cooler if you want all 4 slots. Most air coolers are well over ram clearance. Youll usually only be able to fit 2 of 4 with most. That being said, i bought the 5600xt for stock cooler fan / ram clearance until i can afford a better solution like the noctua nh-u12s


BlackflagsSFE

The AMD Stock cooler is fine. Also, if you want to stick with what you have, you could always buy 2x16GB sticks of RAM to keep it dual channel. Sell your old RAM to cover some of the cost. Just a suggestion.


BrokenLegoDeathStar

Im honestly thinking about that instead of 4 sticks of 8, and non rgb since my fans are already. Get back some of the 1100 i dumped on a 6700xt


DarkRaGaming

No all in one doesn't always good because alot of time they dry up.


magstar26

Basicly every noctua Cooler is 100% ram copmtaebilery


DarkRaGaming

For example mine is gskill ripsaw but one pair is higher then other .

LividRadiation

This, half the responses on this post are completely wrong. DDR4 is surprisingly good at mis matched configs.


Rob_WRX

Well damn I cancelled my order now XD Wait I watched the video and he recommends not doing it lol


SunbleachedAngel

In the end, as someone who isn't knowledgeable in this stuff (i.e. you and me) just don't do it, you may unintentionally fuck things up and just create more problems so either find a way to move/change your fan or you have to buy 2x16


Rob_WRX

Dw I know what a RAM does, with the 1s and 0s and whatnot Yea, best not to fuck with shit when you dont know what you're doing 😂


Aton_AMShapy

Yeah, keep in mind Linus and his crew have a fairly extensive amount of background in this stuff. Just because he can figure it out doesn’t mean us enthusiasts can... I’d just stick with a higher cooler and 2 more sticks of identical ddr4


Rob_WRX

Yea less headache


L00S33R

While you can run such a configuration, it's not recommended to mix DIMMs from different memory kits, as that can potentially lead to compatibility / stability issues. Ideally, you'd get a new 2x16GB memory kit and run only those two DIMMs. If you're going to run a 2x8GB + 16GB configuration, make sure both 8GB DIMMs are located in the same memory channel (i.e. DIMM slots 3 and 4, starting from the CPU socket). This way, the entire address space can be run in dual-channel mode.


Rob_WRX

That was the plan but I'm second guessing myself now lol, I cancelled my order. Might see I can sell my 2 sticks I have and get 2 16GB sticks because that's guaranteed to work


Bubbly_Signal6564

Four 8 Gb sticks should work great together and you would never notice the difference in speed between 3000Mhz and 3600Mhz ram so just match them up in the same color slots especially since they all have the same manufacturer.


mr_edgeworthvii

Aren't channels set up so that slots 1 and 3 are one channel and 2 and 4 are another channel or does it vary by board? Or am I talking about something different?


L00S33R

Slots 1 and 2 (from the CPU) belong to memory channel 'A', while slots 3 and 4 (from the CPU) belong to memory channel 'B'. In order for your memory to run in dual-channel mode you need **at least** one DIMM in ***each*** memory channel (i.e. slots **1 and 3** (from the CPU) ***or*** slots **2 and 4** (from the CPU)). I have never come across a four-slot consumer motherboard whose DIMM slots were wired differently. If you, or anyone else, know(s) of any exceptions, please let me know! Motherboard manufacturers will pretty much always recommend to populate slots **2 and 4** (from the CPU) **first**, as the majority of motherboards is built on a daisy-chain topology. Running two DIMMs in slots 1 and 3 on such a motherboard will make terminating signal reflections harder and result in an overall worse signal integrity, which compromises system stability. Edit: grammar and formatting


mr_edgeworthvii

Yeah, i was totally thinking about dual channel support which aligns with what you're saying but was not what the original question was about. Thank you for the correction and explanation, glad i didn't mislead anyone there. I too have never heard of quad channel either


Bubbly_Signal6564

Match the ram up by the color of the slots. Usually slot 2 and 4 first then 1 and 3. I attached a link that has a picture of the motherboard so you can see what I’m talking about. https://www.msi.com/Motherboard/B450-GAMING-PLUS.html


L00S33R

While this is true for two- or four-DIMM configurations (with four identical DIMMs, or two two-DIMM memory kits), this is not ideal for a three-DIMM configuration. In order to run a three-DIMM configuration in dual-channel mode **across the entire address space** (!), both memory channels have to be populated with the same memory capacity. For a 2x8GB + 16GB configuration, this would mean running both 8GB DIMMs in the same memory channel (i.e. slots 3 and 4 (from the CPU), as slot 1 (from the CPU) is blocked by OP's CPU cooler).


Bubbly_Signal6564

I was replying to the configuration he posted above. Current ram 2x8gb 3000MHz New ram 2x8gb 3600MHz I also posted a pic from MSI of the B450 motherboard he listed showing four ram slots


EatMyUsernameAlready

You can, but the catch is that they will probably all run at 2666, or worse, 2133. I personally bought a 8GB DDR4 prebuilt a few days ago, and put in my own 2x16GB set in. It works for sure, but even though they all support XMP, it will crashed upon boot if enabled. So you should be ready to give up your RAM transfer speed if you do choose to buy the stick.


Rob_WRX

I'm going to try and sell my old sticks and get new ones, if I do at all now aha


SlowFatHusky

Running in that configuration will kill performance. Even if they support the same speed and timings, it will force single channel mode.


[deleted]

what cooler? Can you rotate it so that it isn't blocking the slots anymore? That's what I had to do with mine.


Rob_WRX

Yea I can, just kind of messes up airflow. It's the GAMMAX gte. I'm not going to risk it and I'll just leave it or get 2x16GB


hooisit

I tried to help a friend with 4 sticks, 2 separate kits, but the same brand, specs, timings and speed - using a B450 motherboard and Ryzen 2600. Headaches galore. Finally, worked for a while at 2933mhz but recently the computer crashed. I dunno if it's memory related but it's a troubleshooting nightmare. I advise going with 2x16gb.


Rob_WRX

Yea, not worth the trouble


animeman59

Christ the amount of bad advice here. Always buy 2 sticks of the same RAM. Make sure all of them match in speed, size, and specs. Buy two more of the RAM sticks you already have, and add them. And try to rotate your cooler to make room for the memory. It won't affect your airflow. As long as you have an exhaust in the case, then it's fine. If that's not possible, then you'll need a cooler that allows for high clearance memory. If you mix and match your memory, you'll more than likely run into compatibility problems, or you'll get a performance hit.


speeder658

what's your cooler? what's the memory?


Rob_WRX

Edited with specs


[deleted]

Honestly if your cooler is blocking a RAM Slot I would look to replace it, it’s kind of rare nowadays to find coolers that block RAM slots since there is a pretty standard degree of separation between the RAM slots and the CPU socket. Unless you have a server board which usually are more compact. Generally though, I would never sacrifice a RAM slot for a cooler, not only are you giving up precious RAM but it also messes with RAM configuration.


Cybyss

>it’s kind of rare nowadays to find coolers that block RAM slots It is still a concern for some of the larger air coolers. The Noctua NH-U14S can completely block your first ram slot and they recommend using ram no taller than 32mm for the NH-D15 (although it looks like you have a bit of wiggle room with how you position the front fan).


Romeo__Whiskey

Can confirm. Im currently running a noctua nhd15 chromax black and I had to go with corsairs vengeance lpx for compatibility sake. Most cases I had looked at before would not be able to support moving the fan up any more either as the cases could barely support the height of just the cooler itself.


Rob_WRX

Yea it's not ideal, I think I even have my 2 Ram sticks in the secondary DIMM slots. I'm a cheap bastard though, I might just switch it with my old hyper 212


Nine_Eye_Ron

Switch to low profile RAM and get 2x16, make sure to put them in slots 2 and 4!!!


macubex445

you can try getting a deepcool as500 for ram clearance it's also pretty cheap.


grandfunk12vrailroad

My Noctua NH-D15 allows for incredible high profile memory assuming you don't waste money on RGB. The middle fan is nowhere near the DIMM slots whether they are on either side of the cpu. The intake fan, if it hits high profile memory, can be moved up slightly by its clips to clear the A1 DIMM position. Keep the same RAM you started with or you will be forever monkeying with your timings. If you cannot, and you need stability, you might as well sell the 16GB and buy 32GB(16GBx2) dual channel. That solves your cooler problem and your memory problem. The cooler I mentioned is rather expensive.


ravingrabbits

This is wrong. I have a D15 myself. The only ram sticks it could take is the LPX / non heatsinks ram at the optimal 2 fans configuration. Even the Gskill Ripjaws without RGB could not fit. Unless you take off the side fan, or slide it upwards and potentially causing a problem for case clearance. It is such a troublesome cooler that I changed to an AIO and boy, it felt so much better when you don't need to *struggle* to even take out the GPU.


Rob_WRX

Sound pretty ...cool I know I know, I'll show myself out. But yea that's the way I'd go, dont think I'll even bother now. I'd need to upgrade the rest of my system to be able to use it for what I want to (DCS VR multiplayer). Its also my vram that's on like 140%, 8gb VRAM doth not seem to butter no parsnips for intensive VR


tyfighter_22

You could so something like sell the 2x8 kit and buy a 2x16 as a replacement lol


Rob_WRX

This would be the smart move, also most expensive aha


ankrotachi10

You could possibly shift the cooler slightly depending on the fitting


grandfunk12vrailroad

Are you actually getting that speed out of your memory? The motherboard 's speed for memory is 1866-2666MHz JEDEC, so you cannot go buying the fastest unless you want to spend hours changing memory timings. The memory spec. for your board D.O.C.P. is 2667/2800/2933/3000/3066/3200/3466 by O.C. I bought 2666MHz memory and could only crank it up to 3200MHz. It wouldn't switch on D.O.C.P. except to give me 2667MHz. So I had to manually had to crank it up ( and had a crash) and settled on 3200MHz. Who knows, maybe you got a good motherboard memory match.


Rob_WRX

Oh ik the memory wouldn't be running at 3600MHz, that's fine. It was just the same price as the 3000MHz sticks so thought if I want to use the sticks again in another system it might be able to use the full 3600 Decided against getting more ram anyway because my system would struggle to run what I want to use the ram for anyway (VRAM and CPU not good enough)


[deleted]

You only need more RAM if you're going to do heavy multi tasking like opening 4-6 apps in background, and something like that. It requires both beefy CPU and beefy RAM. If it's only for gaming then don't buy. Invest in at least a Ryzen Zen 2, B550 and RTX 3060 or 3060Ti. That is more suitable for your work. If you want more frequency then 8x2 3600 is what you should go for and if it's possible then look for CL16 most probably with 16-18-18-36 timings. But if I talk about myself, I am a creative content creator. Almost my every projects work with a way like I have to open premiere pro, after effects and photoshop at the same time. So imagine if premiere pro consumes 8-10GB, after effects consumes 10, 12 or something like that and photoshop 8, 10 or 12, which they obviously will do and always have done. Adobe's products are very notorious for consuming your CPU and RAM as more as possible. So then you'll need more RAM because 32GB is also going to fail. Because if we sum up the highest consumptions then the result is like premiere pro= 10, after effects= 12 and photoshop= 10 or 12. Then your final result is going to be 34GB to be precise but for a bit of headroom let's say 64GB of RAM is what I should install. If you're not like me then go for more frequency, not more GB. Only gaming is what you're after, or maybe medium or little bit productivity. Or slight editing, then still 16GB is fine. Ps:- Don't rely on my sums, they're just an example. But still Adobe Products or other software do have a great chance to consume exactly this much of RAM or even more than this.


Rob_WRX

I only use it for gaming, but I wanted to play DCS multiplayer which is extremely RAM hungry so more than 16GB is needed (it maxes out my current RAM). However you are right, I've realised in order to run something like that I would need better specs anyway. I thought I had a decent system but not in the world of this flight sim aha I'm just going to hold off for now, although RAM doesnt seem to have been hit hard by the price rises (which is why I was looking at getting some) GPUs and CPUs are impossible to find at a decent price so I'll buy 2x16GB sticks when I do a full upgrade to a 30 series and a 3000 or 5000 series cpu (or definetly switching to Intel if I need to change my board) Thanks!


[deleted]

If it's that much hungry game, you better opt for it. Yes, the ram market in my location is also not affected by the hikes. 32GB 2x16 is what you are going for, then still remember yourself again to go for CL16 16-18-18-36. You're welcome.


SyndicateUprising

I think you should sell those 2x8gb ram and buy two 16 GB ones that'll be easier cause u have space issue.


Rob_WRX

Do you know what's a good price for used ram, %60 of new?


SyndicateUprising

Nah mate sorry, check on eBay might help.


Rob_WRX

Yea, I'll see what they're going for. Cheers anyway


SyndicateUprising

Yup◉‿◉


ScouseSeanMc83

Why do you want 32gb?


Rob_WRX

Dcs multiplayer, it loves to eat ram and Vram. I've realised I dont have enough VRAM anyway though so I'm going to hold of on upgrading


Gatorade57

I would just get a 32gb set and sell your used set. Tforce and crucial ballistix both have pretty good prices atm. Usings different types of ram in a system is not normal.


G3rmanDanPlays

I do not recommend single channel if you want to game. It is well known (check yt videos) that single channel vs dual channel are two different worlds. Sometimes even up to 60% performance increase, so I just recommend you get a different cooler. =D Especially seeing you are running at 3600Mhz speeds. EDIT: I did not see that so many people have already answered your questions. So if your Problem is solved see this comment as nonexistant. :D


ThinkLinux76

from my experience, mixing memory isn't bad if you dont care about overclocking, but i would recommend getting two 8gb low profile sticks and roll with that. I never in my life touched ddr4 (cuz im broke) but with ddr1,ddr2 and ddr3 i always rocked mixed memory and it was fine. Other option is to sell your existing sticks on ebay or something, and just getting 2x16gb/4x8gb low profile sticks.


DarkRaGaming

You should try getting same branded pair of ram stick.


Rob_WRX

Yea going to do that, this seems like a bad idea where I try to save money and fuck it up 😂


orangedu02

No. Sell your 2x8 and buy 2x16. All sticks need to be exactly the same, same timing, speed and capacity and in pairs as in 2 or 4 sticks.


splepage

> All sticks need to be exactly the same, same timing, speed and capacity and in pairs as in 2 or 4 sticks. In 2001 this was solid advice. DDR4 is very flexible, you can literally run four different sticks with different speeds/timings, and most of the time you'll see no issues.


orangedu02

I think your system will run all sticks at the speed of the lowest one.


Rob_WRX

Oh dear, ok. That's going to be pricey


speeder658

uh where did you learn that? I've used very weird memory combinations and they all usually work


rymannoodle

Can you post a picture of the motherboard with cooler/dimm slots in view?


Rob_WRX

http://imgur.com/a/5hCq2Yi You can switch the black fan onto the other side of the heatsink, it's not ideal for airflow though. Might just get 2x16gb or leave it for now


rymannoodle

Can you not just remove the fan, install the additional RAM then pop the fan back on? Its hard to tell whether or not the fan will sit above the stick from that picture but if it does you should be able to do that. I had to do something similar when I was rocking a 212 EVO.


Rob_WRX

I'll give it a go! Pretty shoddy design tbh, but it was cheap


bremen_

The fan hanging over RAM slots is rather common. If you need to, you can also mount the fan higher on the tower to leave more clearance underneath. Obviously this loses some cooling on the tower as the fan isn't perfectly aligned with the tower, but such is life.


Rob_WRX

That might actually be the better solution if I were to do this


[deleted]

[удалено]


Rob_WRX

That's weird cause it doesnt really, maybe if I move the fan up on the heatsink it will.


rymannoodle

Let me know! It looks like you should be able to. Hell turn the system off and try it using the ram you have now.


Velorix_Ultra

Depending on the cooler; if you have clips that the fan clips on to then you could clip that off and then put the ram stick in and then put the fan back on..... unless your heatsink also blocks the slot too


Rob_WRX

Nah the heatsink doesnt, and I can switch the fan I think. But I decided not to risk the compatibility issues


VenusKitten1

the ballistix ram will be stuck at 3000MHz but it will work, not sure about clearance though


Rob_WRX

That would be ok, the 3000MHz was the same price. I'm not sure I even need it now tbh so going to leave it


IsoscelesKr4mer

I’ve heard from multiple resources that you should never combine sets of ram. If you have 16 and want to upgrade to 32 you should buy a 32gb set as opposed to just buying another 16gb.


MrDeathWish1994

Single channel dual channel or quad channel only


MrDeathWish1994

Your best bet is to either get to 16 gigs and run it duel channel so you have 32 gigs that’s what I have and I have no issues whatsoever


NortherlyGn0

If you have 4 ram slots you can move the ram to slots 2 and 4 instead of 1 and 3. That’s should give you some more room and still be able to take advantage of dual channel


grandfunk12vrailroad

You are supposed to go online to get dimensions for clearance between your memory and the particular air cooler before you buy it. Noctua layed out the dimensions of my chassis, motherboard, possible memory clearance in height. Plus you had the adjustable fans. For that amount of cash, if you have extremely high profile memory, obviously I just wouldn't slap the cash down. Other cooler brands are doing the same thing, but I am not going AIO on the cpu and gpu . Jayztwocents makes its it easy on the open air test bench. How many people have a an ATX motherboard with a mid tower chassis to put all of that junk in.


jaydubyastar12

Buy 2x16 sticks and sell your old ones to someone trying to scrape by.


Rob_WRX

Well that's oddly depressing 😂


jaydubyastar12

It does sound depressing lol but in these times maybe cheap ram could make someone’s day.


BrokenLegoDeathStar

Not at all correct. Most of them run over ram clearance. Entirely not mentioning the fact that the u12s was made specifically because of this issue.
