Things To Know Before Buying 4 Stick of RAM 

I knew I'd run into problems with 4 sticks of RAM but bought them anyway. Glad I could find a description on what the issue is. Thanks!

It's a year after you uploaded this video now. I have a simular situation. I have an Asrock Steel Legend B450M with the newest BIOS. First after my build 6 months ago I installed 2x8 GB sticks from Corsair 3000 Mhz and everything worked fine. I have also overclocked it to 3333 Mhz and tuned the settings and everything worked also fine. I have now upgraded with the same Corsair adding 2x extra 2x8 GB 3000 MHZ. First I have load BIOS default and then put XMP which worked perfectly fine. Then I overclocked it to 3333 and it also worked fine for me. Then I tried to tune the timings and I could not reach the same as with original. I was experimenting and have managed to set so much as possible timing which worked stable. I could not set every timing setting as the original but 80%. Everything is working fine and fast. Read and write spead have increased 10%. Asrock B450M Steel Legend is also LOW-to-MIDRANGE motherboard. So, this is my experience. Type Corsair RAM is: Corsair Vengeance LPX CMK16GX4M2B3000C15 ... I'm wondering how is the situation now? Cheers. (Sorry for my bad English :)

Thanks for telling me I found this video when I was think of buying an extra 2x8 GB ram for my pc but I already have 16 GB so I’ll stick with 16 GB for now, thanks man!

Even high-end b450 boards have the same issue, wherewith 2 stick of ram it can oc up to 4200mhz but with 4*16 it can max of till 3466mhz. It would be best to check the QVL while purchasing ram

Refer to your MOBO MANUAL!! I recently purchased the B550 gaming plus and after reading the manual I’ve learned I’m able to clock higher speeds using 2 sticks of ram rather than 4 sticks of ram! 1DPC 1R max speed 4400mhz 1DPC 2R max speed 3866mhz 2DPC 1R max speed 4000mhz 2DPC 2R max speed 3600mhz

Yeah I also had a very similar issue, that's what I get for cheaping out on my board I suppose

I found this video in time, thank you very much!

I’m literally having the same issue I’ve bought 2 identical, 8gb DDR4 3200mhz Corsair RAM sticks, to go from 16GB to 32GB. And my b450 plus motherboard, just doesn’t want to know. It tells me that there is hardware failure or whatever when I do a memory check. Thing is.. I’ve sent it back and replaced the RAM already... so it’s not the sticks. And I’m banging my head against the wall not being able to find anyone online who understands what the feck I’m trying to describe “Ooooh did you click it in, ooooh well you must’ve damaged it” Like NO, fuck... I’m more than capable of clicking in bloody ram, Jesus Christ... So yeah, it’s lovely to see it’s not me, and it’s actually a known issue Thanks for the vid bud

This is a limitation of the Ryzen Processor, each processor has a max mhz working speed for 2 and 4 slots of ram.

Great I was about to do just that, thanks for the head's up.

I run 64 GB (4x16) of G.Skill Flare X DDR4 DRAM in my Ryzen 9 5900X gaming/video-editing PC build and set the DOCP to 3200 MT/s (mega-transers per second) on an ASUS Prime X570 Pro ATX motherboard. Everything runs fine. I run 64 GB (4x16) of G.Skill RipJaws V in my Ryzen 7 5800X work PC build and set up the DOCP to 3200 MT/s on an ASUS Prime B550m WiFi micro-ATX motherboard. Everything runs fine in this PC as well.

Good to download CPU-Z and check the timings that the XMP settings actually launch into. Have found with many boards, even though running at the xmp profile speed in MHz the Xmp timing profile, if individual timings are set at "auto" good chance they are not running per the XMP profile. Even possible to increase latency even though you have increased MHz if timings are too loose. Something to keep an eye out for. Need on many occasions to adjust settings like CAS manually in bios to ensure you are getting benefit of higher MHz.

why only 127 views for such a great video, why are you so unpopular ?

Yes makes perfect sense now, I have 64gb of 3600mhz and a tomahawk b450 max and the normal speeds of 3600 is too high so I’m going to try down clocking them today. The ram issue kept failing my flight installation until I used only 1 stick of ram. Thanks

I had 2x16GB of RAM on my X570 MOBO a nd 2 months ago I bought another 2x16GB and it works fine, both kits were 3600MHz CL19

Same isue. B450 Aorus PRO, Ryzen 5 2600x and 2x8 G.Skill Falre X running at 3200MHz -> no issues I added after 2 years 2x8 more of the same RAM sticks and I have only issues, like you described, PC shuts down when going into sleeping mode and won't boot (fans start and cycle but PC doesn't boot) and sometimes it boots with the RAM at 2133 MHz instead of 3200 MHz

It may also be that the voltage to the ram is too low, so it cannot run at full potential.

Yeah, this is a tricky issue. I lowered the timings, the frequency, pushed more voltage, sometimes it takes days for me to get a BSOD error. It's pretty random. So, yeah, look into your motherboards. it was stable at 2666 with super low timings and it was stable at 3200 with only two sticks. But I couldn't get it to work without lowering the frequency from 3200 to 2800MHz and tweaking a lot the timings.

You can get more speed but your memory has to be single rank. Then 4 sticks will be more improved over 2. And usualy single rank memory is 8GB and under. 16GB sticks and above are usually dual rank. And there will be no speed up.

It´s not the board I guess. I´ve got the same issue with my x570 tomahawk. Running 2X16 gb ram 3600 Mhz runs perfect. But when I ad 2 more sticks to get a total of 64Gb ram it won´t run above 2600 Mhz

Interesting point!

Well, if frequency difference is not that big, it may still be better to have 4 modules, because of dual rank thing. 4 single ranks sticks is like having 2 dual rank RAM sticks. And as I have heard, having more than 2 dual ranks does not give that much performance, and dual rank is harder to overclock, but it still gives a little more performance. Thanks for the video!

This video saved me from wasting money on 2 new sticks. Thanks!

felt high watching this because this makes sense but is so overlooked, you made it sound like you were dissecting the brain of the PC lol

i remember doing this years ago. :)

2024 and my ASROCK B365 phantom gamer 4 will not run 2666mhz GSKILL AEGIS ram at all. It ran this ram for 5 years total 64 gigs (4) 16gig ram sticks. As of July 2024 and a windows update my system will not run any memory module over 8gig of ram and 2 sticks in dual channel. System was freezing in windows all the time. I thought it was my 9th gen i9 9900k so I repasted it and then changed the AIO from a 2 fan to 3 fan larger cooler. Still would freeze in window. Finally I had to buy new Corsair 3200mhz Ram 8 gigs sticks. System runs stable for now and no freezing.

Hello thank you for your video. I'm running 2 pairs lpx 3000 on 3800xt x370 msi gaming plus. Haven't tried to overclock yet, but prime 95 all day. On 1st gen ryzen I couldn't get stable above 2666 with one pair. If this helps anyone else.. 👍

Hi. I ve read at multiple forums that adding 4 sticks can cause stress and load to memory controller of motherboard.is it true? And could it affect my board's long term functionality?

unfortunately i had this issue after i have had this mobo for years now..#FirstPCbuildever that being said i still loved the vid and ty for the information.

I’m actively going through this issue and after a lot of bios boots I’m pretty sure I have a definitive answer Mobo: Asus m5a97 Cpu: AMD FX 6350 BE Ram: 2 2x4gb gskill ripjaws x 1600 9 9 9 24 (16gb total) My board has OC Tune option that I took advantage of to get data. when I run one set of dimms I can set the D.O.C.P. (Amd’s xmp) to the advertised profile but freeze shortly after booting OS when running all 4. I noticed the boards auto tune wants to set the freq down with out changing timings but stock setting keeps the freq and loosens the timings. It seems that when running 4 dimms dual channel with the DOCP profile, you will have to manually raise the dram voltage slightly to make it stable or make a choice between advertised timings or freq. I think just about all g.skill ram has a heat sink so raising the voltage slightly to achieve stable advertised settings shouldn’t be detrimental, especially if you know your cooling is solid. I have not made any tests with a specific 4dimm dual channel kit and honestly I can’t find one to buy lol

Great video, good to know this!

I have 4x8 3000MHz on an ASUS Z170 PRO GAMING (w/ i7 6700K): Default (no XMP) 2133: works XMP2 3000: NO POST XMP2 2933: slightly unstable (memory errors) XMP2 2800: works

Right now 32gb 2x16GB 3600mhz seems to be the sweet spot for my 5900X machine, 3733mhz is the best speed for Ryzen chips it’s considered Ryzen tuned ram I plan on getting a 64gb kit of 3733mhz ram eventually

The Motherboard is REALLY important. I would recommend a ASUS B450 F Gaming 2 it can take 128 gb of ram and 4 sticks with no problem.

I tried to double the amount of ram by adding an additional 32 gb of ram. After installing the sticks, my P.C will not boot. I will go on and off for a few times, then will just sit doing nothing. Is there something else I need to do to my bios to make this work.

I ran in to the same issue, with the ASUS Prime B460 plus and my 3200 4x16 hyperx fury sticks of ram, it only worked at 2933 Mhz.

you should have tried driving the dram voltage a bit harder 1.38-1.4maybe

I'm planning to buy extra ram 2x8 3200mhz so in total to have 32gb ram for my build. Tut z490 wifi 10700k 2x8 3200mhz Do you think it will work fine?

Hey, Thank you for the amazing video. I still need help on this subject and if you could help me, I appreciate it. It's a fast question, I guess. So, I have an MSI B360M PRO-VDH board with 4 DIMMs, up to 2666mhz, it's a Dual channel motherboard. I'm currently using 2x4 DDR4 2400mhz from G.Skill (Aegis), similar to the video but different frequence and memory size. I want to add more 2x4 RAM sticks (same exact type from G.Skill), so I can have 16GB of RAM. That means I will fill all of the 4 slots. Will this work normally? If I place the second kit in A1/B1, will I successfully get the 16GB of RAM? I did some research and it appears that the motherboard (and every dual channel board does this apparently) will read A2/B2 as a 8GB RAM slot, and A1/B1 as another 8GB slot. Makes sense but I would like to hear from you!

Late comment but made it’s cause it’s newer ram? But I bought 2 more 8x2 to have 32 to my existing one same brand and everything had no problem clocking it to 3200mhz or anything

I’m having this same problem, but with a high end motherboard. (Msi X570 gaming edge WiFi with gskill Ripjaws v 3600mhz 4x8) and it crashes at any frequency above 1866mhz unless I take two sticks out. It helps if I up the dram voltage but it still crashes after a workload.

I hit the same issue when i added 4 x 8gb sticks. Rated at 3600mhz but with 4 sticks is only stable at max 3200mhz. I am not losing sleep about it tho

I have the exact same issue on my msi z390-p. 2x8gb 3000mhz, works fine. 4x8gb fails at every setting. Even as low as 2166...

Looks like that this is a common problem on the first gen Zen based processors and cheap motherboards with daisy chained 4 slot of RAM. It's less of a problem for Zen 2 and newer chips. I have a budget system with a brand new Athlon 3000G + ASRock B450M Pro-4 F R2.0 bundled together and 2 stick of SK Hynix DDR4 2400T, the cheapest DDR4 memory I could find. I can overclock the APU to its limit easily (4 GHz on CPU @ 1.3v and 1.7 GHz on GPU @ auto) but I'm struggling to get that RAM to anything over 2800 MT/s even with 1.4V. I thought, well, those are cheap 2400 MT/s modules, what should I expect? Then I realized I actually put those RAM in the wrong slots (A1 + B1). Moving them to the correct slots (A2 + B2) allows me to bump the speed to a stable 3200 MT/s with the same timings as the stock speed (DDR4-2400T) at 1.35V. So for this system, 2800 MT/s is the best speed slot A1 and B1 can reach. I'm thinking of adding 2 stick of 8GB memory with the same JEDEC specs to it just to see if it can run those 4 stick of RAM at that speed AND with a mixed module size.

I got the New z690 board with an i7 12700k :) 4 sticks of 8gb 3600mhz ddr 4 ram cl 15 :) Working wonderfully! Hell, I even put it to a 1:1 ratio haha. Not a single issue. Beautiful FPS gains over 2 sticks.

same issue

I have a Tuf gaming b450 plus II mother board with 2x8gb ram im thinking about going 4x8gb but i dont understand what benefit does dual channel have over quad?

same issue here...with my B450M mortar Mobo with 3200 mhz 32gb (8gbx4) RAM.. thanks for pointing this out... im getting MSI X570 Unify next week.. hope i can use all of my RAMs sticks, instead of just 2.... cheers bro!!

TLDR make sure the mobo supports 4 sticks well.

My corsair rgb pro 3600mhz 4x8gb had the same issue yesterday when i installed them from a 3200mhz t force 16gb kit ... Had to put them on 3000mhz to be stable using 4stick .... On my asrock b450 pro4 i max out at 3200mhz

i have this issue broo you the best i have b550 w 2 rams of 8gb 4000oc and i add 2 more same rams and doesnt go up to 2133 i will move to x570 to see if they can go farther!! thanks

let me tell all the ppl about that somebody he is talking about... he is no other than --- hardware unboxed guy :P

So was it not working at 3000mhz on the first boot? Would it say so in CPU-Z or just lie to you? Whenever I boot computer from fully off, it clicks on and off along with the fans, is this the same thing or is that normal?

So I am planning on buying a 3900x with 4 sticks of RAM. But should I get 2 instead? Running it on an x570 tiachi motherboard. I am seeing things about Ryzen 3 CPUs being "dual channel" and having 4 sticks is not the same as 2 sticks with same total RAM. HALP!

so if your board can support it 4x8 sticks is better?

ROG Z490E motherboard , 3600MHz 8G*4 G.skill(Royal) can not stable run games or memory test.

4 years ago

my motherboard says it can run 32 GB XMP at 3200 MHz but it runs fine with 2 slots but not with 4 slots being used it sometimes freezes or weird loud noise then crashed

4 sticks of ram? And I'm over here using 24 sticks of 128GB of ram 😂😂😂😂

Hi, i just found this video after having a similar issue on my Asrock B450 fatality K4 Mobo. I have 2 * Corsair LPX CMK16GX4M2B3200C16 3200mhz 8gb sticks. all ran fine at 3200 XMP 2.0 in the BIOS. I added 2 more sticks of a different brand (on sale) same clock speeds etc, but found lots of BSOD issues etc. So i returned the sticks and purchased a set identical to the set i already have in the ,machine. The BIOS will not accept higher than about 2800mhz with the 4 sticks in. reading online this seems a common issue. The main thing i cant nail down is, i run a Ryzen 5 2600X cpu, but i cant tell if this is a memory control issue with the 2xxx series cpu, or if its a MOBO BIOS issue. I have seen that the 3xxx series ryzen CPU's are better with memory compatibility, but the question is, do i keep these sticks and run them at the 2800 for now, OR upgrade to a 3600/x CPU and see if thats happy, or upgrade the motherboard to a higher spec AM4 socket and stick with the 2600x. i.e. do you think this is more of a cpu incompatibility rather than the mobo itself?? thanks :)

Thank god my msi x470 board can run 4 3200 MHz ram with ez

I have 2x16gb = 32gb (works well) I added another 2x16 (4x16) not posting…. Im losing sleep!!

I have a BSI 450 TOMAHAWK MAX motherboard . Currently g skill ripjaws 2 x 8gb. I want to add two other rams 2 x 8gb to it. Is this okay?

So uh, question. I'm building a PC for content creation, and I know I need RAM for that. Will the 4 stick kit (Corsair Dominator Platinum RGB 4x16GB kit DDR4-3600) work with the MSI Prestige X570 Creation EATX AM4 motherboard currently heading to me from China? Or should I go with a two stick kit of 32gb? Thanks, and Adepto Bonum.

Hi, I have a B450 pro4 motherboard and I have 2x4 GB ram at the moment, I want to upgrade it to 16gb ram. If I buy another pair of 2x4 GB ram I will get 4x4 GB ram. Will it work fine? And I don't know if b450 pro4 supports quad-channel? (sorry for bad English, I'm 15 from the Netherlands)

I have a asus tuf x470 with radeon 7 ryzen 2700x with 4 x 16 sticks of corsair veng. Rgb. 3200 And i cant get it to to go past auto setting as soon as i try to enable my setting beyond auto I run into memory issues i can run 2 sticks easy and run at rated speeds but cant do 4. Looking at getting another x470 motherboard cause not sure if there is any fix.

Strange....got 4x8GB 3200MHz CL14 working on x470 with an older Ryzen 1700. Maybe Agesa Updates got this working ?

When I put 4 sticks of 16gb 3200mgz Corsair vengeance pro ram pc doe not botot it takes me to a screen that says boot failure and says do you want to boot into bios load defaults or optimized defaults. Well I go into bios and set ram to 2133 pc boots when I bott all 4 sticks at 3200 mgz the dram light is on. All four sticks worked fine at 3200mgz and booted on my b660 ds3h ddr4 motherboard. when I go boot pc up the next day I get dram light, but all 4 sticks works. Pc booted fine with 4 sticks at 3200mgz for about 6 months. Until recently. But when. I put 2 sticks in it runs at its rated speed and pc boots up

Can you plz check something? I see you have the F4-3000C16D-16GISB model. I also have 32 (4x8) gb F4-3000C16S-8Gisb on my gigabyte ab350 gaming 3 with no issues. Can you check and see if cpuz identifies your ram as single rank or dual rank? Some people reported that ram kits working on dual channel are in fact identified as dual rank when all 4 dimms are covered on motherboard. Thx for the video.

I have a dual channel cpu but my motherboard is quad channel can I run 4 sticks of 8gb ram? Even though my cpu is dual channel?

Hello.. i would like to ask about my build..i was using a Trident Z neo kit with 3600mhz and it was working fine under 3400mhz and i decided to buy a new kit Trident z RGB with same timing and mhz as my old neo was.. but eventually after putting the new kit it wont boot and change to lower frequency like only 2400 mhz even im using the D.OC.P it wont work.. any possible way to reach my frequency to 3400mhz? By the way im using ryzen 5 3400g with b450m-plus II tuf board...TIA

I have a z590m gaming x motherboard and I have 8x2 16gb ram installed can I add a single channel 16gb ram and enable xmp?

I have problem with my ram i have 2x8 gb 3200 mhz i add 2x8 gb more so i got 32gb but my pc at 3200 xmp is unstuble it crashes and gives me blue screen i set the ram 3000 and all its fine.. i dont kbow what to do now keep the 32 gb at 3000 or 16 gb at 3200?

this mobo is daisy chain or T- topology?

What about msi tomhawk b450max

can i ask something i installed quad ram . so 32gb tforce delta r 3200 mhz . so i look it in to the bios its only reach 2133mhz . and i change it frequency ram 3000mhz not reaching the 3200mhz. and still the same . please help me ..... :/ i have B450M MORTAR MAX MSI QUAD INSTALLED 32GB TFOCE DELTA R RYZEN 5 3400G

cpu is ryzen 5 2600&my motherboard is asrock b450 steel legend and i already have g skill aegis 2x8gb ram so can i put 2 more 8gb aegis ram in it?i'm not very understand with ram...

i've got 2 sticks of 8gb ram each already, what happens if i do purchase 2 more sticks of 8gb ram each (totalling to 32gb ram)?

I have a similar situation, I have a Ryzen 5 3600 paired with a b450-f gaming MB. I have 16 GB 3600 MHz I have decided to get an additional 16 GB 3600 MHz when I put it into my system it put the speed at 2133 I slowly increased the MHz till it could only peak at 3200mhz this all happened about 4 days ago I have also done some voltage checking and some research apparently I need a Ryzen 7 3700x to be able to run 4x8 32GB 3600mhz I want to get the maximum capacity of my ram but I don't want to get a new CPU I plan to get a new MB specifically the ASUS ROG Strix B550-A Gaming will I be able to run 32 GB 3600 MHz? paired with my CPU please help I have been searching for days and could not find an answer. ( if you have motherboard sugestions please recoment what motherboard will give me peak performance for my system)

With Asrock b550 steel legend ryzen 5600x do you think I'll have a problem?

My gigabyte x470 cant handle 2x8 3600mhz ddr4 ram stable, i think its the memory controler on the ryzen 2700x cpu hope with a 5800 ryzen it will be better🙄

Late comment but i have b450m aorus elite with xpg d10 kit 2 8gb sticks running at 3200mhz cl16 Wanna upgrade 32gb ram, going to add xpg d50 rams same specs as i cant find my exact ram kits, good idea?

the ASROCK b450 steel legend 4x 8gb 3200hmz its okaY?

So max 2733hz you recommend.

3700x asus x570e 4*gskill 3600 c16 gtzn at 3600 14-15-14-28-42 1t without any problem

I had this issue with my Ryzen 7 1700x with Gkill trident 3600mhz with MSI B450 tomahawk. Issue i discovered as the same my board only supported 3466hz

I have Ryzen 3700X on B450 Tomahawk Max board with 8GB x2 3200mhz G.Skill Ripjaw V RAM. I want to upgrade to 32 GB, should I buy another 8x2 pair of same model or go for 16x2 3600mhz (since I'll buying new so why not get higher frequency)? is there any disadvantage or drawbacks or potential issue of having all 4 ram slots filled up with ryzen 3000 CPU? please share your experience :)

I bet those RAM sticks are dual-rank, and that motherboard only supports 2667MHz with 4 sticks of dual-rank.

Is there a difference between 2x16 at 3600 MHz and 4x8 at 3200 MHz? I’m getting an x570 taichi

So should I take 2x16gb 3200 or 4x8 3200 same latancy?

Thanks for video. i get %10 more fps when i use 2 sticks instead of 4 at same frequancy and timings. Also ram latency is about 44ns at 2sticks, 53ns at 4 sticks. There are many videos on youtube shows 4 sticks are getting much more fps because of rank difference. Do you have any idea what is wrong?

At 0:55 you can clearly see where your problem began. You indicate that you are using TWO kits. The problem with memory is that it is extremely figidy. Using two kits, even if its the same exact mfg., the same exact model and part number will ALWAYS cause these results. The only real way to use two kits as a 4 dim setup, and get positive results, is by buying them at the same exact time, from the same vendor, and ENSURE that they are both the same version of that particular module part number. Corsair, for example, always places their module version on each stick. Buying two separate kits from Corsair, each showing for example (Ver. 5.31) will ensure you are getting the same frequencies and times and the same XMP file on all 4 sticks. Any change between two sticks, ie version, times, frequencies, will trigger the error that causes the Bios to continuously boot up until it resets all settings to default for a proper boot. Even tho the sticks you are using seem to say 2019 Mar, in march there could have been three revision’s to that particular module number. Also, even tho the CL times and frequencies might have been the same, any changes to the xmp file will trigger an error and thus prevent you from using the max performance of the sticks. Things to Take Notice On: *Another problem with going from a 2 stick bios config to a 4 stick bios config is that the Bios will SOMETIMES need to revert back to default in order for it to properly set 4 sticks into a dual channel config. Its not always the case, however, it is heavily dependent on the mobo and the bios being used. * The ultimate performance determinator will be the CPU. Memory is exclusively controlled and managed by the CPU. The type of CPU (AMD v/s Intel) will HEAVILY determine the performance of ANY memory configuration. Dual Channel, Quad Channel, Single Channel, 2 dims, 4 dims, 8 Dims, ALL will be determined, controlled, and adjusted by the CPU. The bios simply negotiates terms under which the CPU either accepts, re-negoitates, or totally declines to operate in. In your case, it was “re-negotiated” at a lower frequency.

Hi nice video but i have one question: i've 4 sticks of ram with 8gb on each stick i bought a gigabyte x570 ud and booted into windows everything worked but the ram clocked with 2133mhz i've heatd that this is the normal ddr4 speed. So i went into the bios and enabled xmp (these 4 sticks are rated at 3000mhz and are all exactly the same from corsair). But now the computer doesnt boot into windows anymore. Then i looked back in bios and only 2 of 4 had xmp enabled. I set everything back and my pc worked again. Do u know how i can run all 4 sticks at 3000mhz. Hope u could Unterstand me im from germany

Hi! Same situation with my Ryzen 5 1600 & MSI B350 Mate. I have 4*8 G.Skill Flare 3200 Mhz 14 timings, and it's working perfectly 2*8 with profile 2 (3200) but together only 2933Mhz. Still hope for new Bios but with time less and less. Don't want come back to 2*8 but want more speed. :( Only one way - change processor and motherboard?

Just ordered 2 extra 8gb of the same ram and speed for my B450M/ac. So I’ll have 4 sticks running at 2666. I’ll comment tomorrow if it doesn’t work hahahaha

Disregarded.

Dude read AMD's website they specifically said AMD CPU's does not like 3000MHz RAM.
