Hi guys, I'm kinda new here and need help for my decision for my RAM upgrade and still new on overclocking.. Here is my current set:

Ryzen 5 1500x
MSI B350 Tomahawk Arctic
Corsair Vengeance LPX 2400 2x4GB - CMK8GX4M2A2400C14

Any higher speed RAM recommendations for the latest BIOS and what brand?

If I just upgrade the size and just add 2 more Dimms. like 4x4GB 2400mhz. Would this still be good and run in 2400mhz using the B350 Tomahawk Arctic board?

Can't guarantee 2400 MHz, but you might get lucky.

I also generally don't recommend mixing RAM. Even if you buy the same model, there's no guarantee that it would work with the old RAM.

I might be more inclined to just suggest getting a 2x8G kit instead for now, and then after you install the 2x8G kit, try installing the 2x4G kit as well and see if it works.

We've had users who have had issues getting 2 kits of a 2x4G kit to work together, but then they switch to a 4x4G kit or 2x8G and it works fine.

DDR4 is very very finicky, much more so than DDR3 ever was. And it's because of that, that I wouldn't recommend getting another 2x4G kit and hoping for the best.

Thank you for the information, let's wait for other's opinion. If almost all has the same then I will decide to go for 2x8G and sell my old one.

Apologies is this has been answered.

I have a Bazooka 350M Ryzen Motherboard that came pre-installed with 16gb (2 x 8) sticks of 2400 ram. I need my system to have 32 gigs because I do video editing and the current set up isn't performing very well (I max out ram usage easily).  

The current ram is an OEM ADATA brand.  Is it OK to install 2 more sticks of 8 gig ram from a different brand if it's also 2400?  Or is that too risky?

If I have to buy a new set of ram,  am I OK with  2 x 16gb dimms (2400 - 3200) or do I need to use 4 dimms (4 x 8gb)?

Edit: this is what I was just looking at:

CMK32GX4M2A2666C16 (2 x 16 2666) Which is in the supported Memory List for the Bazooka 350M.

I really wouldn't mix memory.
Do a search here, read a bunch of posts, and you'll find people having issues mixing DDR4 memory on the Ryzen platform all over.
Your best bet would be to just do 2 x 16GB and be done with it.
I wouldn't expect speeds higher than 2400 MHz though, even if the memory supports it. Ryzen isn't well known for handling large amounts of memory and getting high memory speeds.

I don't recommend to mix rams by frequency together but buy two more rams at the frequency of the others...

Thank you for the response. I'll just go with the CMK32GX4M2A2666C16  Corsair 2666. I've been researching for days and I'm falling behind.

I think I've reading too much online and I'm getting caught up in the 3200 recommended clock. But perhaps that's mostly folks going with 16 gigs or lower for gaming. I definitely need more ram than anything.

4x4Gb 2400Mhz will run ! no problem !
I have 4 sticks of 8Gb 3200Mhz , but the highest i can go on 4 sticks is 2400Mhz , on just 2 sticks i can get 3200Mhz .

Can you tell us the specific brand and part number of the RAM you get 4 sticks to run at 3200MHz?
Be really nice to see what components you have in your system that accomplish the performance you are getting.

thank you

Just thought I'd offer an update.

I purchased and installed 32gb of ram a few days back for my system, which runs a Bazooka 350m and a 1700 CPU.  I "played it safe" and went with CMK32GX4M2A2666C16 (2666) Corsair Vengence LPX since it's on the list.  Really wanted higher speed ram but the 32 gigs is more important over speed for  video editing.

Due to all the issues I fully expected some flaky problems and that is indeed the case; but it's livable for now. Every fresh reboot the ram resets itself to 2400 on my system.  The BIOS shows 2400 at the top of the screen.  So  after a system restart I go into the BIOS I double check to make sure the memory is set to 2667 under advanced settings/OC/Memory section (which it is every time, contradicting the information at the top).  So I have to save and exit even without changes to get the system to reboot and change the memory to 2667.

I'm also currently using Ryzen Master to OC the system. When I originally attempted an OC in the BIOS I was unable to boot into BIOS or Windows so I had to clear the CMOS. Going to try it again sometime down the road when I learn more.

Anyway, I have to run Ryzen Master in Windows, apply my settings in Ryzen Master (3.6gig OC for now) then restart, enter BIOS to save an exit as per above, and boot into windows to get things correct.

Update question for my issue:

I have a Ryzen 5 1500x
and a MSI B350 Tomahawk Arctic.

My current RAM was:
Corsair Vengeance LPX 2400 2x4GB - CMK8GX4M2A2400C14 running XMP profile 2 @ 2400hz
---

Will this RAM upgrade could run at 2667hz using xmp or manual?
CMK16GX4M4A2800C16 is a 2800hz 4x4GB Corsair Vengeance LPX.

or can anyone here recommend a good 16gb ram?

So I bought and built an MSI Tomahawk B350 with a Ryzen 5 1600 with CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Desktop Memory for AMD Ryzen Model CMK16GX4M2Z3200C16.  Running XMP profile 2 it runs at 3200MHz with zero problems since about 2 firmwares ago.

Not sure if that helps anyone, but it seems to be a good combination for me.

If I only install two sticks of 8GB each, of Corsair CMU16GX4M2C3200C16B in my MSI X370 Gaming Pro Carbon board using the current release BIOS 1.90 and set the XMP profile automatically to XMP2, I get 3200MHz and it boots every time.
Buy a dual kit, not singles. A dual kit is a better technical performance match.
Do not try 4 sticks of ram, hardly anyone can get 3200 with 4 sticks.

My system is listed below.
I made a mistake, buying two kits of 2, now I only get 2933 with all four.

You have a chance to learn from my mistake

I have an MSI B350m bazooka with ryzen 1600@ 3.8 GHz...
I successfully overclocked my 16GB Kingston hyperx (2133 Mhz) to 2800MHz without any boot issues...
though it only overclocked upto 2666Mhz in older bios, the new one (the one with agesa 1.0.0.6b update) is like a boon to me.
I can clearly see the difference while playing games and video editing..
though I would recommend everyone to use only dual channel RAM setup as single channel ones(like mine) are painfully slow sometimes

Hey guys. Frustrated B350 PC MATE owner here. My RAM does not work.
 
 
  
 BIOS is the newest (from last month with AGESA Code 1.0.0.6b and updated memory compatibility) and the kit (RipjawsV F4-3200C16D-16GVKB) is supposed to be supported (different color in the list, last two letters different).
 
 There's 2 XMP profiles, 3066 and 3200MHz and neither works. PC turns on, turns off, turns on, turns off and so on until I cut the power with the PSU switch so that the BIOS resets itself. Currently running at a measly 2133MHz. :censored:?!
Same ram, but on x370 gaming pro carbon, same problem. Tried kinda anything all i get is a black screen and restart.

Wow. So skimming the first couple of pages here, I'm being led to believe that the compatibility list, which I specifically chose my ram because of months ago, doesn't mean anything, and I was expected to understand this without being told.

After three days of failing to get my ram working at the promised speed, coming here and discovering that has left me a bit speechless. Like I actually have to step away from the computer to deal or I'm going to end up writing something that gets me banned

It's the physics of it. Just because the memory is rated for 3200 MHz, doesn't mean the CPU's IMC will work at that speed as well.

As far as compatibility lists....those lists are done with pre-production chips, most likely cherry picked to work great to make the product look great. Intel does it, and I'm sure AMD does the same. 
I've seen many engineering samples that get higher clocks and work much better than the general chips from production. It doesn't surprise me.

All things being said, it does suck. I get it. Everyone was really duped into thinking it had much better memory capabilities, but that just isn't reality.

sorry my eng.
Memory should be stuck like in the manual, and not as used to. I still ran the CMK16GX4M2B3200C16R on the x370 gaming plus 
(with the latest BIOS 5.50) at 3200 frequency, not 2933. It's all about slots if black (one of which is closer to the socket)
then maximum 2933 and reboot
if higher and stable 3200 if in red..All the problems are not even in the memory chips, but the fact that people stick memory in the wrong slots (red or black)

After reading the horror stories of this thread, I feel blessed that I was able to get my RAM (G.Skill F4-3200C14-8GTZSK) to run flawlessly from the moment I built my rig in July/August at 3200 MHz with solid timings simply with the XMP2 profile on my X370 Titanium.  When my younger brother built his rig using a different manufacturer's motherboard, I recommended he go with the same RAM, and he had no issues with it there.  My experience has been that it's one of the best RAM kits out there for Ryzen at the moment.

I'm able to as well on my X370 Carbon, but with Corsair Vengeance. There have been a lot of BIOS updates to help (at least in the X370), though I'm not sure about the B series.

I feel like assuming higher than 2400 should be the goal since that's what Ryzen needs.

However, I did find my higher OC instability was due to vdroop, and had to fix that in the BIOS with whatever the CPU voltage regulator is called. I forget at the moment.

So I really believe everyone should be able to hit 2993 - 3000 range, but other things might be in play as well (such as the above mentioned vdroop).

Hi everyone,

I'm using combo AMD Ryzen 5 1600 + MSI B350 Tomahawk (BIOS v14). And I have two kit of RAM as below:

  • GSkill Ripjaw V 2666 15-15-15-35 1.2V
  • Corsair Dominator Platinum 3200 16-18-18-36 1.35V

I've tried to push my Corsair kit to 3200MHz with XMP and manual setting. But it doesn't work, it will end up with boot loop. Otherwise, I can reach 3200Mhz easily with my Gskill kit and it's running stable with this frequency. Currently, I can only reach 2667Mhz with my Corsair kit and no more.

Here are the settings that I use to set for my Corsair kit:

  • 2133 15-15-15-35 1.2V - PASS
  • 2667 15-15-15-35 1.2V - PASS
  • 2933 16-16-16-36 1.2V - FAIL
  • 2933 16-16-16-36 1.35V - FAIL
  • 3200 16-18-18-36 1.35V - FAIL
  • Enable XMP - Boot loop

Please let me know if you have a way to reach 3200Mhz.

Thanks

Alright! So I think I should stay at 2667MHz. The thing still makes me concern is why I can push my gskill kit up to 3200MHz easily. Weird!

It depends on the CPU IMC and the chips used for the DDR4 modules. Simply put, 3200 is gambling.
With brand new CPU, 3200 might look stable for some users, but after a while most of them get into stability issues and "abnormal" behaviours.
The best spot (performances / stability) for the current Ryzen CPUs is around 2933 Mhz.
If your CPU is rock stable with that DDR4 speed ... :biggthumbsup:
Otherwise AMD guarantees up to 2666 MHz, so it's better to stick with that speed.

I am about to purchase an X399 Gaming Pro Carbon motherboard to use with a AMD Ryzen Threadripper 1950X. The sales person at Fry's said that they do not have any 4 x 16GB compatible memory in stock. He said there was an official memory compatibility list on the MSI website. I can seem to find it. If such a thing exists an someone please provide a link? Thanks.

https://www.msi.com/Motherboard/support/X399-GAMING-PRO-CARBON-AC#support-cpu

there just click on the memory Tab and away you go!


What does rightmost column on the memory compatibility chart mean?  (2 4 8 DIMM)

Does this column indicated the maximum number of DIMMS that I can install for that particular model chip?

This chip is available at a local computer store (Corsair Vengeance LPX 16GB DDR4-2666 PC4-21300 C16).
Part Number: CMK64GX4M4A2666C16

I was hoping to purchase 4 of these today and 4 more in the future...but I am hesitant to buy them because that last column seems to indicate that I can only install 4 of them. Can anyone please confirm this?  

Also...this chip is listed on the MSI compatibility chart but it says (ver4.31). Where is the version typically listed? The sales person is telling me that he does not see this spec listed anywhere.

Thanks.

Hi

It only tells how many sticks has been tested. If a kit contained 2 sticks, then obviously they couldn't test 4 as that would mean different kits.
Anyway, no motherboard manufacturer is able to test all available RAM kits on the market.

Buying 4 now, and another 4 in the future is RAM mixing, which in case of DDR4, is very risky idea.

Thanks. I assumed that it was only important for them to be the same memory and in matched pairs or a matched quad. I have not seen them being sold in bundles of 8 x 16GB.

8 x 16GB put a terrible stress on the CPU IMC.
2133 MHz is the best you can get in most of the cases.

I think you're maybe looking at this the wrong way...;)  You are thinking of filling all the available ram slots as opposed to how much total ram you want.  Decide how much total ram you want, then divide that number by 4--and away you go.  Forget about filling all the slots with something, imo.  Four of them gives you the same quad-channel support you'd get with 8 slots, while providing a much simpler hardware environment that is likely to run better, faster and with less trouble than trying to fill all 8 slots.  It all depends, of course, on what you want to do.  If you intend to run the ram at its guaranteed speed instead of its XMP theoreticals, then you could likely fill all 8 slots with no trouble--mixing and matching 2 sets of 4 DIMMs becomes much less problematical as your MHz demands for the ram drop toward the guaranteed levels.

I'm gonna be straight up here.  I'm pretty pissed off.  And I am totally *not* happy at all with my Ryzen 1600x + MSI X370 gaming pro carbon, and it's most likely the last time I ever buy anything MSI or an AMD processor ever again.  A lot of this is AMD's fault, sure but when you put ram on your QVL that's rated for certain speeds, the customer needs to trust that.  That's literally the only thing we got to go on.

I'm quite literally considering RMAing this CPU + Motherboard + ram in one go.  And keep RMAing motherboards, processors and ram until I eventually hit the silicon lottery and get some combination of parts that runs at specified speeds.  Some of you need to understand that if I build a brand new gaming PC, and one part isn't running at specified speeds, then the entire rig is junk.  Might as well haul it off to the dump, or donate it to the Salvation Army.  Hyperbole, sure, but I'm 50% the way there.  My ram will literally not run any higher than 2667mhz CL 14.  That's too slow.  One notch lower on the CL or one notch higher on the frequency = won't boot.  I've spent the past week doing searches, looking for any and all guides on OCing ram, just to see if there was one setting I was missing or overlooking, nope.  Will not run any higher than 2667mhz, period.   And that's not good enough. 

If AMD doesn't fix these ram compatibility issues with updates sometime next year, and they just ignore the problem and move on, I'm 100% guaranteed to never buy anything AMD ever again.

*Updade* I just spoke with someone at newegg, and they agreed to offer me a full refund on the ram, and I'm curious if there are any MSI memory experts here who can recommend me a DDR4 3200mhz kit that's guaranteed to work with the XMP profile on an MSI X370 gaming pro carbon motherboard w/Ryzen 5 1600x?  Because unfortunately the next step might be refunding this MSI motherboard and going with Gigabyte or Asus.  The customer service rep assured me that if I have *any* issues with any more components not working to my satisfaction that they'd issue a full refund.  Considering how much money I've spent with them over the years, and that's a point I made abundantly clear when I requested a refund.

There isn't a single RAM kit that will *guarantee* your desired speeds. AMD made it clear, that max they can guarantee is 2667MHz.

As MANY times mentioned here and in other topics, it is down to the integrated memory controller (IMC) in the CPU. So even though motherboard supports 4000MHz+, and you can buy 4000MHz RAM, it doesn't mean your CPU will be able to handle such speeds.

To be any close to 3000/3200MHz on AM4 chipset, your best bet would be GSkill FlareX

The the performance of the IMC in the CPU is random?  Similar to how some CPUs are better overclockers than others?  Should I just RMA Ryzen 5 1600xs until I get one with an IMC that'll run ram at its specified frequency?  All I gotta do is tell newegg that the memory controller in the CPU is bad, and they'll send me another chip.  Ryzen runs considerably better on faster ram.  I'm losing out on a bit of performance by not running 3200mhz.  I quite literally need every ounce I can squeeze out of Ryzen to push a 1080ti.  As long as I can get 3.9-4.0ghz OC + 3200mhz ram, I should be fine though.

What you need to understand, is that you paid for a CPU that will run memory at 2667 MHz guaranteed.

If you want it to run faster  guaranteed, then buy a super expensive one that is guaranteed to run at those speeds. Some resellers will actually go through and bin the CPU's to make sure they reach certain specifications. That costs money. There's fallout expected from it. Why do you think AMD didn't guarantee 3200 MHz instead of 2667 MHz? 

I didn't complain or get mad at Intel when my old 3770K couldn't go past 3.9 GHz reliably. Or couldn't push memory much past 2000 MHz. It's just how things work. 

If you don't win the lottery, do you go back to the corner store and keep claiming your ticket was faulty and that they should replace it until you win?

I have the exact same configuration as you meaning x370 pro carbon v1.9 last bios and ryzen 5 1600x and i have corsair vengeance 8 gb 2 sticks 4gb each at 3000 mhz cl15-17-17-17-35.
It's working just fine at 16-17-17-35 and 2933 mhz, occasionaly some cold boots triple beep, no problem there just stops and starts again and it's working so you either got the most lewl imc ever on your cpu or i dont know but considering i can do 2933 with corsair, they have micron die not samsung, i would say the cpu is the faulty one.

In that case I'd recommend you give up personal computing completely then, because *nobody*--not Intel, not AMD, not ram manufacturers "guarantee" overclocked speeds.  Nobody does.  Not for ram--not for cpus.  So pick up a console--you'd be happier, I think...;)  1600Mhz on the ram is an *overclock*, period. It's not guaranteed--doesn't matter who makes the ram, it's not.   The guaranteed speeds are much, much lower for the ram; and the only guaranteed speed for any cpu--regardless of who makes it--is the *stock* speed.  Period.  Try and digest that. The misunderstanding is yours--not anyone else's--not AMD's nor MSI's--it's you who has misunderstood.  Learn the difference between "overclocked" and "stock" if you think personal computing is something you want to stick with.

Every heard of JDEC?  SPD ratings?  XMP (A-XMP with MSI) extreme overclocking profiles?  Suggest you begin by boning up on those topics.  It's easy to understand--it's not rocket science or quantum mechanics...;)

Know what you mean...I have the X370 Pro Carbon AC, latest bios 2.5, and an R5 1600 and on stock auto voltage I do 3.7 GHz @ 1.256 V max; and my ram (see sig) does 3033MHz every time without fail @ CL16 15 15 15 36 1T on stock voltage, Gear down, ram voltage Auto @ 1.355V.  I'm very happy even though I am 66MHz shy of being at 3200 on the ram (1533MHz vs. 1599Mhz)...;)  Most of these kinds of configuration problems are user error, but rarely it is true you might pick up an occasional faulty component--but it's very rare in my experience.  Without a doubt however the odds of picking up 3 or more "defective" components at once, if purchased new from a reputable source, are effectively nil.

I never paid for a CPU that is only 2667mhz guaranteed.  I agreed to no such limitations.

Anyway, your point is completely moot because newegg has agreed to not only refund my memory, but replace my 1600x processor as well.  If Gskill Flare X 3200mhz CL 14 doesn't boot and run at those speeds (perfectly stable), then I'm going to RMA the CPU next, guaranteed.  Or possibly the motherboard as well.  So yes, I can and will keep RMAing processors until I get one that can run ram at a proper speed.

Here are some facts for all the teenagers and "enthusiasts" around here:

https://www.msi.com/Motherboard/B350-TOMAHAWK/Specification
Supports DDR4 1866/ 2133/ 2400/ 2667(OC)/ 2933(OC)/ 3200(OC)+ Mhz *
Obviously, the overclocking profiles are NOT guaranteed.

https://www.gskill.com/en/product/f4-3200c14d-16gfx#tabs-spec
Rated XMP frequency & stability depends on MB & CPU capability.
So 2400MHz is guaranteed, but 3200MHz is not.

https://www.amd.com/en/products/cpu/amd-ryzen-7-1800x
Max System Memory Speed : 2667MHz
So 2667MHz is guaranteed, but 3200MHz is not.

Subject closed (from my point of view).

Mainboard: HC85
Processor: Zilog Z80 3.5MHz
System RAM: 48KB
Video RAM: 16KB (only 6912 bytes are used for Pixel Shader effects)
Video Card: integrated (16 colors)
PSU: 5V/3A
OS: BASIC Spectrum Sinclair

note: NO overclocking!

I never paid for a CPU that is only 2667mhz guaranteed.  I agreed to no such limitations.

Anyway, your point is completely moot because newegg has agreed to not only refund my memory, but replace my 1600x processor as well.  If Gskill Flare X 3200mhz CL 14 doesn't boot and run at those speeds (perfectly stable), then I'm going to RMA the CPU next, guaranteed.  Or possibly the motherboard as well.  So yes, I can and will keep RMAing processors until I get one that can run ram at a proper speed.

You don't need to agree to it. You AGREED to it by just buying the chip. That's the specs on the chip. Whether you want to deny it or not, you aren't entitled to getting 3200 MHz. No one is. 

Let me guess, you're the kinda guy that goes to buy a little Ford Fiesta, then returns it because it doesn't do 250 M/h down the highway, even though it's pretty well known it can't?

Sorry son, but you can keep RMA'ing it. Newegg will very quickly blacklist you once it finds out about it and tests the CPU and find it working just fine. Good luck.

Hello, i buy memory DDR4 2x8GB/3200 Team T-Force Vulcan Gray (TLGD416G3200HC16CDC01) but i can't start it on frequenzy more then 2800.  My motherboard - msi b350 pc mate.  XMP dont work.  I try change procODT, but it have no result, i can't start even at 2666.  I try use Ryzen calc, and use his settings, but it not help.   Maybe you can help me?

same boat here. I bought a Ryzen 1700 , MSI x370 gaming plus, and literraly the best DDR4 kit available (TridentZ 3200CL14 , samsung B-Die)
and yet it won't boot past 2800

My guess is that MSI boards lacks the "DDR4 voltage boot" that is available on ASUS boards.
so even if you set 1.35v DDR voltage in bios, at boot it's set to auto (1.2v) then it bumps to 1.35V, after booting. But if it can't boot, it will never reach 1.35v

I got the segfault bug when compiling on linux with my first Ryzen 1700. RMA'd it. the new one comming directly from AMD show same behavior : at 2900 it won't boot.

so yeah i'm wondering if I try to resell this mobo to someone would find 2666/2800 okay , and buy an asus
OR sell everything and wait for the next ryzen+ and x400 chipset this spring. samsung announced better ram chips too

So I expect 3200 to be much easier to reach for the next stepping, maybe at 4.3 Ghz or so
since i have a 4790k i am not really urged to upgrade, it was more like an impulsive buy since i am an amd fan

I dont know how you cant use the gskill at 3000mhz, considering i have the corsair vengeance black with micron dies and it works like a charm at 2933 mhz, occasionally some cold boot issues but after that works like a charm, maybe you need to check your timings, i dont know mine works best with 16-18-18-36 or 16-17-17-35, if i go lower they wont work, 1.36v, and 1.135 on soc voltage. X370 pro carbon tho the motherboard last bios 1.9.
