Hi guys I have a problem with my MSI B450 GAMING PRO CARBON AC and Corsair vengeance RGB x4m8x3600c18
I have the newest BIOS and I could set up ram up to 3400mhz with xmp do I need to change timings if I used xmp profile?
How to unleash the extra power?
Btw I have ryzen 3600

On website this ram is supported and msi managed to set up it to 3600 on single and double channel.
There isn't just some magical way to make it work. 

If you haven't read parts of this thread, you probably should.

Getting fast RAM speeds isn't just about changing to XMP and getting it to magically work. Not all CPU's (especially AMD) will just support it with any given RAM out of the box. Often, given AMD's poor AGESA code, it requires manual tweaking to get it running well at high speeds. 

Latest BIOS isn't always the best option. For the X370/B350 series boards, the older BIOS's are actually more stable, and operate much better than the newer ones. The same could be said for many of the newer X470/B450 bios's as well. 

Realistically, you'll probably be manually tweaking voltages and possibly timings to get it to work at the rated 3600 speeds.
Or just be happy with 3400, save yourself 2 to 12 hours, and not be as fast as the DRAM possibly can support. (If you can't tell, I'd choose that option.....as things deteriorate over time, you'll be tweaking again).

I have a b450 tomahawk max that doesn't work well with ram. I have two memories (2x16gb ddr4 3200mhz .. Features: - Brand: Rise - Model: RM-D4-8G-3200D   Specifications: - Capacity: 16GB - Frequency: 3200Mhz - Type: DDR4 - Frequency: 3200 - CL15?17-17-35 1.2V - Latency: 15 - Pinout: 288 pin DIMM   Package content: - Diamond Rise Mode Memory) activates xmp on A1b1, does not work activating xmp on A2b2 .. even with xmp active it only works 2400mhz.setando manual, with voltages, nor beep. Another card with another ryzen processor got normal. I upgraded and changed the card no longer takes 3200mhz

CL15 or other uneven CL's only works with GearDownMode disabled, and that often means you have to go to 2T command rate

or XPM putting you at XPM +1 CL

unfortunately it has done this for me too on a mortar max with a gskill 15-15-15-35-50 3600 1T  kit , with xmp enabled it runs at : 16-15-15-35-85 1T but atleast it's stable so far.

New to these forums, I have a semi-general question about Ryzen and Memory support, so figured I should probably post here rather than create a new thread. If that was wrong, please let me know.

I have a MSI B450 Carbon Gaming Pro AC motherboard running a Ryzen 5 2600X processor. I have two different sets of RAM (details below), neither of which is on the QVL for this mobo, but still working/can be tweaked to work. I am trying to figure out what is the best setup I can get with what I have on hand, and thus some general questions and maybe a specific one after.

First, the RAM that I have :

1) Geil Evo Forza Gaming - 2 * 4GB DC Kit (GFR48GB2400C16DC) - 2400MHz CL 16-16-16-36 1.2v
2) HyperX Predator - 4 * 4GB QC Kit (HX421C13PBK4/16) - 2133MHz CL 13-13-13-36 1.2v

As I said earlier, neither of these kits is in the QVL, but they work (somewhat) ... The Geil works perfectly, no problems in more than a year of usage. The HyperX, I bought used recently, and its not so straightforward here. It works perfectly when I use two DIMMs in DC mode. It works so well in that mode that I was able to simply use the "Memory Try It" thing in the BIOS (updated to the latest version) to get it up to 2933MHz and run stable (and it POSTed at 3200MHz too, but at CL18, so I dropped it down to 2933 CL16).

Now, the reason I bought the HyperX kit was because I wanted 16GB. If I install all four DIMMs, the BIOS says 4 DIMMs are in use, but reads only 8GB. Windows 10 says 16GB RAM (7.95GB usable). Task Manager shows 8GB as Hardware Reserved. CPU-Z shows 16GB and all four slots populated.

To rule out any motherboard or CPU issues, I mixed the Geil and HyperX RAM. At the moment, I am typing on a machine running 2 Geil DIMMs and 2 HyperX DIMMs, with frequency set to 2400MHz and timing set to 16-16-16-36 (basically I put the Geil settings in manually). It seems to be perfectly stable and I am not seeing any issues yet. But with the HyperX, no such luck. And no, the RAM is not dead, I tried all four DIMMs individually and confirmed they work fine.

I don't game at all, but I edit videos with Hitfilm Express and Davinci Resolve. Best I can tell, for my use, I do not really need blazing fast RAM (though Ryzen directly speeds up with RAM), and higher capacity is more important than raw speed.

Now the general questions:

1) I know mixing RAM is a bad idea. But just how bad is it? More specifically, is it bad because it slows down, or is it bad in other ways, like does it make the system unstable and unreliable?

2) I saw some bits and pieces at various places that suggested upping the voltage might get the "half my RAM is missing" problem to go away. Is this something to explore further? Would tweaking the voltage and a few other things possibly get the HyperX RAM to work with all four DIMMs installed? If this is a possibility, can you please point me in the right direction?

And a specific question:

Given that I don't game and so benchmarking stats are not important to me, would you agree that its okay to just live with the Geil and HyperX combo, or would you advise me to sell all 24gigs that I have and replace it with a "certified working" 16GB DC kit?

Thanks for any inputs you can give me. And again, if I was meant to create a new thread, just let me know.

Hi, 
I just wanted to ask if the officially supported memory list that is posted on every motherboard page's support is "retroactive".
For example, the memory that I'm going to buy has been officially tested for the Ryzen 3000 series, does that mean that it will work flawlessly with the previous generations of Ryzens? 
Thank you.

That's not possible.
The max memory speed (guaranteed) for Ryzen 1XXX is 2666MHz.
The max memory speed (guaranteed) for Ryzen 2XXX is 2933MHz.
The max memory speed (guaranteed) for Ryzen 3XXX is 3200MHz.
But those speeds are guaranteed only in case of 2 single-rank modules.
In case of dual-rank modules or 4 memory modules everything is degraded with 266MHz (at least).
Of course, overclocking and overvolting combined with a bit of luck (high quality CPU) can lead to higher speeds.
But again, nothing is guaranteed.

Hi All

thought i have a quick ask here before the RMA process.

I have an X570 Gaming plus and Ryzen 5 3600. 16GB Corsair Vengeance RGB PRO 3200.

Sytem will only post with one module in B2. I've tried every bios available cleared the CMOS several times and also tried a friends Corsair Vengeance LPX 2133MHz with the same results. Only boot with one module in B2.

Is there anything i'm missing here?

Memory problems like this are pretty easy, but time consuming, to figure out.

1. CPU
2. CPU socket
3. Motherboard
4. memory socket
5. memory

If you're sure each stick of memory is good, then you can eliminate #5.
For #4, check the sockets with a magnifying glass to ensure that the 'finger' or pins aren't bent out of shape.
For #1, just check to ensure the CPU is OK underneath.
For #2, check to ensure the socket is OK. Most likely it is, since it's an actual socket and not pins (like an LGA socket).
For #3, it's basically if nothing else is wrong, that's probably the problem.

Hi guys!

I have a problem! Did not read all pages in this thread, because is long. Sorry!
The problem is slow memory write (G.Skill FlareX 2x8GB 3200 CL14) on MSI Gaming Edge WIFI. Memory is overclocked to 3600MHz. Please see the pictures:

 




Want to ask, why write speed is so slow? Read is double! What can I do?
Thanks! :)

You can see that older CPU's 1800X and 2700X have a much faster transfer. Hope somebody from MSI staff to help!

Remove OC from memory, and see how it behaves at 2133MHz.
As well as try setting it to 3200MHz as that's what the CPU supports.
Mind that higher frequencies does not always give better performance.

Good morning, forgive me the bad English.
I have an MSI MEG X570 UNIFY, on which I have installed this RAM memory kit "G.skill F4-3600C16D-16GTZNC". I cannot start the PC if I activate the A-XMP setting in the BIOS. The settings proposed by the A-XMP profile correspond to those declared by G.skill (3600Mhz cl16 19-19-39) but the UNIFY gives me the debug code number 92 and the POST stops like this.
The slots used are a2 and b2, the processor is an X3900 and the BIOS is the latest official, that of April 2020.
Do you have any idea how to solve, do I make mistakes?
Thanks.

Hello,
I have a MSI B350 gaming plus with an AMD Ryzen 5 2600 and 32GB of RAM (GSkill Aegis 2x16Gb (f4-3000c16d-16gisb)).
I'm planning to buy another set of this RAM to have 64GB for some virtualization works.
Will this configuration worl without any problem (4x16GB sticks) ? I will NOT do any OC of any kind so the RAM can work at 2133 MHz (default parameters I have at the moment) but i would like to be sure my system will be stable.
Have a nice day

I tried a very similar SKU from G.Skill with the same timings on my X570 MEG ACE and it works fine with XMP in the BIOS (I used the 32GB dual rank kit, which should actually be less stable than 8GB single rank DIMMs).

What I would check is the voltage; when I switched from the CL16 ram to the CL14 Samsung B-die today, XMP set the correct speed and timing, but totally undervolted the RAM based on G.Skill's spec on their website. For your RAM it should be 1.35V, per G.skill. When I installed my CL14 32GB 3600mhz kit today it wouldn't boot until I found the auto setting had the voltage below G.Skill's posted 1.45V. Once I set it correctly I was able to boot no problem, and I even have it OCed to 3733 with an FCLK at 1867 for 1:1.

If fixing the DDR voltage doesn't work, set the ram speed to 2133mhz with the same timings and see if it boots. It's entirely possible you got a bad kit, but generally my experience with G.skill has been pretty positive, and I would point the fingers at the BIOS first. I do know my experience with the CL16 kit is that the SK.Hynix chips are a little more flaky than Samsung, but that's par for the course. I've run both a 3200mhz and 3600mhz dual-rank kits and both leave little room for overclocking; G.Skill bins these to the very edge of what they're capable of, which means everything has to be set properly for XMP to boot and be stable.

You can also try bumping the SOC voltage by .1V, but I would do that as a last resort as it shouldn't be necessary for the XMP profile to work.

In general I've found the "auto" settings to be a bit odd on these boards (this isn't isolated to MSI as almost all the X570 manufacturers totally mess up the stock voltages). Either it drastically overvolts (in the case of the CPU) or undervolts the DRAM (despite the XMP profile clearly stating what it should be). Check out the JayzTwoCents X570 overclocking video on YouTube for more details, albeit on an ASUS board.

FYI for MEG ACE owners, avoid 1.92Beta at all costs if you overclock, at least with Samsung B-die. I tried 1.92Beta on my MEG ACE with a 3900x and F4-3600C14Q-32GTZNB RAM. Where I was stable at 3733 with 1867 FCLK on 1.8, I now can't get anything past the XMP profile settings even after rolling back to 1.8 (and 1.92 wasn't even stable with XMP). 

Avoid 1.92 Beta at all costs if you care about memory OC. It seems to have actually made memory compatibility worse, and I've seen another report on Overclockers.net other than myself stating that it's borked even after rolling back to 1.8. That is not cool.

I am writing because not one company supported me with this issue and I wasted a lot of time and money fixing this.

Playing games, the computer would restart or freeze. Dbug indicated memory corruption, which was untrue. Called MSI, Cyberpower, G.skill and bricked my 350m motherboard. Words of caution:

I did receive some stability by tuning the ram down.

Do not update your bios on your motherboard - MSI boards are very finicky.

This is what worked. Do not plug Ram into the white slots, it must be in the black slots, and if you have only one stick of ram, it must be in the DIMM a2 slot. After correcting this, the system runs flawlessly. I have never encountered this before on any other motherboards, and was astonished that MSI would not have a diagnostic tree on this.. 

I will tell you, that tech support at all of these companies are a waste of space. This will be my last MSI/amd build/buy. 

Specs:
Bazooka 350m /450m
G.skill DDR2400
Ryzen 1700x

I mean, if we're honest here....even the manual states to install memory starting at slot DIMMA2.....it's on page 25.
As far as MSI support...if you weren't coming to the forums for support, I can't say much. Given this is your first post, I can only assume you didn't come here at all.
As far as being finicky, I won't deny it. But I don't put that entirely on MSI.....it's MUCH MORE AMD's fault than anyone's.....great hardware, but software/BIOS's done by kids in high school with no clue how to code. Yes, it really is that bad. And yes, I won't be buying AMD hardware anytime soon because of it. 

As far as Cyberpower (I'm guessing you bought a pre-built system from them?), I wouldn't ever buy a system from them. They're notorious for having really poor support.

Good luck in the future. You'll find most OEM's have problems. Asus, Gigabyte, ASRock, they're not much different in that respect.
