Quote from: darkhawk Any of those should work at 2133 at a minimum. They will most likely work at 2400....but it's not certain. I plan on getting these : https://www.newegg.com/Product/Product.aspx?Item=N82E16820232485&cm_re=g.skill_trident_z_rgb-_-20-232-485-_-Product Those will work at 3200 MHz without issue. Another option is the G.Skill Flare X sticks, as those will work at the rated speeds on a Ryzen system.

HI II have G.Skill Flare X. I have this memory on 3200Mhz, but application dont work stabi. Dou you have some tip how set  memory and NB voltage on https://www.msi.com/Motherboard/support/X370-XPOWER-GAMING-TITANIUM.html.

Thx for tips

I installed the beta 1.72 bios yesterday and it has a myriad of new settings. Do you think you could ask support to provide us with a guide for settings that would aid us in reaching higher memory overclocks. I know each dimm is different but there has to be commonality of methodology. I really have no knowledge of many of these value both for timings and voltage. Of course I know dram voltage, soc/cou-nb voltage, . But what about vddp  and so may of the other settings? A users guide to these settings with an advisor who is knowledgeable would be of great assistance to not only ,me , but so many others. Otherwise it is almost like the blind leading the blind. NO aspersions intended, but I think you understand what I am trying to say. Thank you so much for all of your assistance.

Hello all,

I've recently built my self a new Ryzen 5 rig and having issues which do sound alot similar to many of the problems on here.

Spec:

MSI B350M Gaming pro
Ryzen 1600X
Samsung 960 evo 256gb M.2
Team Group Vulcan 2x8GB DDR4 2400 CL14-16-16-31 1.2V TLGD416G22400HC14DC01 (this Ram is on the approved list)
Corsair H100i 
Asus Rog Strix GTX1080 

I have no problems posting and can get into the bios, i am running the bios in opitmised defaults (cpu @ 3.6Ghz and Ram at 2133) and have now had the same issue with 3 different sets of ram.

I can boot into windows without any issues but once in the mouse cursor stutters and lags, and all programs do this as well. I had sent the board and chip back to overclockers uk when i was using corsair lpx ram, they tested on one of their rigs and had no problems with team group stuff so i bought some of that to replace the corsair kit, i'm guessing this is another RAM issue.

Has anyone got any tips on what i can do? I only had time last night to rebuild the machine and get windows on. Will set the ram timings manually this eve and start to bump up the voltage slowly to see if that improves stability.

I will get CPU-Z installed this eve so i can see what everything is set to within windows.

At this time, I'm not aware of any of the new settings that can help improve memory timings.

Realistically, there isn't much that can help with the timing outside of voltage (both SOC and DRAM) and LLC for any board out there. All the other settings that I've seen that were added won't make a huge difference if you're using A-XMP and such.
About the only thing I can really comment on is sticking to even numbered timings. My understanding (this is anecdotal btw....not a 'fact') is that Ryzen apparently likes even numbered timing and odd numbered timing can cause 'oddities'.

I would make a thread in the Gaming Motherboards forum and start there....this really isn't the thread to provide support for that kind of an issue, as I don't believe it's memory related.

Of course yo cannot use A-XMP if you want to use some of the new settings especially with 4 dimms.. I tried upping frequency to 3333mhz with 2 dimms and looser timings, it would not work. With 4 dimms I am still at 2667mhz. The reason I see no change in spite of utilizinmg some relatively obscure settings, is that the 1.72 bios is STILL based on Agesa code 1.04a . I found this out by reading all motherboard data with HWinfo64 a very useful and accurate program. My estimate, only an estimate, is that many of the new settings are not fully functional until the agesa code is update to 1.06 or even the less capable 1.05. I expect more work is to be done and I am glad that this 1.72 beta bios is a step in the right direction.

Let's set just a few things straight...since you're always out for spreading mis-information. I'm quite tired of that at this point.....


1. New BIOS for Tomahawk and Gaming Plus and PC Mate are all based on 1.0.0.6. I know this for a fact.
2. New BIOS for the X370 XPower Titanium is also based on 1.0.0.6. I know this for a fact.
3. There are more and better ways to look into the AGESA version. A version info number in HWINFO64 doesn't really do much anymore, given how many times the OEM's have forgotten to change the version.

All that being said, what more do you want? I'm sorry your RAM isn't working well. If it's that huge of a concern, get better, more supported RAM. Or get a new CPU. Maybe that one will have a better IMC. But things have gotten better for many people. Many are now getting even higher than 3200 MHz, some 3600 MHz and higher.
If it's that huge of a concern to have such fast memory, then find someone who has memory running at 3600+ MHz and get the same memory as them.

Last i checked though, IF doesn't scale much or well after 3000 MHz or so. Granted it was a bit hard to get anything higher than 3200 MHz on most boards, but still. With 1.0.0.6 now, we should be able to see fully how Infinity Fabric scales over frequency. My guess though is that what was true before will still be true, past 3 GHz IF won't scale well.

set geardown mode to disabled - now you are able to use odd numbered timings 

[tim_genardo2]

Recently (finally)had success hitting 3200mhz on my corsair LPX (CMK16GX4M2B3200C16W) after updating to beta bios h.51(release 5/23/17).
I used the memory try me! feature set at 3200mhz with 16-18-18-18-36.
I updated from the old h.4 versions after failing go above 2600mhz on the same ram with any previos bios before h.51.
Cpu is running at 3.9ghz with 1.3875 on the Vcore

My guess though is that what was true before will still be true, past 3 GHz IF won't scale well.

Past 2933 MHz to be more precise.
On the other hand, 3200 MHz with 4 memory modules is not guaranteed with any BIOS, timings and voltages.

[darkhawk]

On the other hand, 3200 MHz with 4 memory modules is not guaranteed with any BIOS, timings and voltages.

Very true....however.....MANY are seeing 3000 to even 4000 with the latest AGESA code updates. I would test it, if I had memory that was more than 2400 MHz right now in my Ryzen system.....

[RemusM]

MANY are seeing 3000 to even 4000 with the latest AGESA code updates.

Yes, but with 2 memory modules only.

[darkhawk]

Yes, but with 2 memory modules only.

One of the moderators here managed 2933 MHz with 4 without any issues. Higher on the other hand, he said he was having some issues.

Even so, 2933 is still a great speed for 4 modules. 



Things can only get better.

[RemusM]

One of the moderators here managed 2933 MHz with 4 without any issues.

We've tested a few dozens of motherboards and Ryzen CPUs.
In two cases 2933 MHz was stable with some Corsair x4 kits.

But I was talking about 3200 Mhz with 4 modules: not possible so far.

Another important note: with brand new components, overclocking might look stable.
But after a while, most of the overclocked components start to fail.

Very true.
I experienced this myself recently with my 1500X.
At first I could easily do 4.0 GHz with 1.3875V.
2 weeks later and it crashes on any stress test/game. So I'm back down to 3.9 GHz.

Sadly, my  memory is only 2400 MHz, so I can't do much there to see how it helps....yet....eventually I'll try and get some good 3200 or even 4000 GHz just to see if it works and how well.

I did not lie if developers forget to update the information string in their bios is that MY FAULT?? Your attitude toward me is totally uncalled for. I have G.Sklil FlareX memory it is guaranteed Ryzen compatible . Its is Samsung B-die memory, the memory that works best with Ryzen. I am NOT bellyaching. I am simply reporting the facts of my situation.   I still have hopes. The bios is beta it can and will undoubtedly be improved.So you are totally misreading my attitude and I wish you would take a deep breath and relax. I have made no accusations against anyone and certainly not against the bios development team.

Lets get something straight. Even if the developer DID forget to change it, it doesn't change that IT DOES HAVE AGESA 1.0.0.6. 
GUESS WHAT? THAT MEANS YOU LIED BECAUSE IT DOES HAVE IT. See? That's my whole point. And then you mislead users. You provide absolutely nothing but controversy in every thread you post. You do not add anything to this forum but problems. 
I've said it before, I'll say it again. QUIT IT. See : >>Please read and comply with the Forum Rules.<<

I've got a little update today, I just tried the latest BETA BIOS rev 1.62 on my MSI B350 Tomahawk, and I'm finally hitting 3200Mhz for the very first time,

Previously, I've been using 2933 Mhz instead due to not being able to POST at all but beeps, however this latest up-to-date BETA BIOS finally supports my memory @ 3200Mhz

I'm using Corsair Vengeance CMK16GX4M2B3200C16, (Hynix- M die) and here's some picture proofs 

 



So yeah, feel free to try that if any of you has the same MOBO and the Ram

[ross]

I've been running my 3200Mhz memory and 3.9Ghz Ryzen 1600 for the last month and a half now on my Tomahawk B350. I've done so across multiple versions of BIOS as they were released.

I'm using 1.62 beta at the moment and am getting the same values. I've been gaming heavily and everything's been completely stable with stock cooler.

Screenshots below show current settings with 1.62 taken today in response to this post was flashed a few days ago though. The last picture if you note the timestamp and BIOS version was 1.5. The settings are slightly different in that to achieve 3200 and 3.9Ghz I needed to disable AXMP and set timing manually. 

The first screenshot is MSI Control Panel and includes the model number of my RAM.

Hope this helps

[RemusM]

The settings are slightly different in that to achieve 3200 and 3.9Ghz I needed to disable AXMP and set timing manually.

More relaxed timings (CAS = 18) and a voltage boost (1.35V) is always a key to success.
Also you have a better chance for a long term stability compared to all those with CAS = 16.


p.s.
Higher speed, stability and tight timings is not possible in most of the cases.

I was running 3200 stable for 2-3 weeks, no cold boot issues, suddenly can only POST at 2933, even with the latest tomahawk beta bios. :/ My kit: CMK16GX4M2B3200C16W

B350 Tomahawk
R5 1600 3.7 @ 1.3V

I know, first world problems. I guess 2933@C14 isn't that bad.

What happens if you up the DRAM voltage to 1.4V, and set the NB voltage to 1.0 or 1.1V in the BIOS?

[rpmrneves]

@darkhawk

Can you please help me?

I have the following specs:

• AMD Ryzen 5 1600
  
• MSI B350 Gaming Pro Carbon
  
• G Skill Ripjaws V 8x2 3200MHz CL15 (F4-3200C15D-16GVK)
  

My problem is: I can get my RAMs to work @ 3200MHz. Sometimes the pc doesn't boot and resets the settings but mostly I can run it after one try with Memory Try It. Everything works perfectly in windows, I ran prime95, aida64 and both of them went well during aproximately 40min each. I even ran a MemTest +86 and it gave 0 errors.
I have the CPU @ 3.7GHz - 1.3375V and the NB voltage @ 1.0625V. I can restart the pc in windows and settings will still prevail (this didn't happend with some previous settings where it was more unstable so it's a good thing I guess). But for some reason when I shut the pc down and only come back after some hours it can't boot with the settings again. It resets itself and I have to change some voltage or the Memory Try to make it boot again and then another time to get it back to the state it was.
Basically: Turn PC On after shutdown --> Boot Loop -> Resets Memory Settings -> Change Memory Try it to 16-18-18-16 @ 1.36V -> Save -> Boots -> Change Memory Try it to 14-14-14-34 @ 1.36V -> Boots -> OK. Why can't it boot after shut down? Sometimes this process can be with two retries to make it boot again.

Thanks in advance

Sounds like you are right at the edge of working and not working (with the current BIOS).

The only things I can suggest at this time is increasing your NB voltage to 1.1V (no higher), and change your DRAM voltage to 1.40V or 1.45V (I wouldn't go higher). Another option is to relax the timings a little bit more in hopes it works better. Maybe try 18-18-18-38 or something like that. 

The best bet might be to just run at 2933 MHz for now and wait for the next BIOS update (I'm crossing my fingers it'll come this week, but I have no idea) and then retry at 3200 MHz.

Let's hope the new BIOS comes this week :D although I talked with MSI support and they haven't even tested my memories yet... So not really that hopeful  on that.

That is not a BETA. That was the BETA of v1.3 which was released already. The BETA for the new one should be 1.41.
At least from the namings I've seen it is as I wrote.

You are correct.
The new BETA hasn't been released yet. I checked my source this morning and nothing new was posted for any board.

No luck. Also that SoC voltage was a typo, I meant 1.160~

hi there
i ordered msi b350 gaming plus motherboard a week ago 
but i took ram support for granted and ordered 2*8 2400 mhz ballistix sport ddr4 memory for it " BLS2C8G4D240FSB", ram did arrive today board is on the way
i didn't find the particular memory model in the msi MEMORY support list and im afraid that the whole thing wont post
what do you guys think ?

Hi

Generally any DDR4 kit should POST. No matter if it's on the QVL or not.
And as it's only 2400MHz kit, you are 90% sure it'll go at 2400MHz without issues.

I know, first world problems. I guess 2933@C14 isn't that bad.

I am not sure if my issue is the same as yours, I was able to run @ 3200Mhz right after flashing the latest BETA [v1.62] then next day, all of sudden it stopped posting and gave me 5 beeps.. I tried changing ram settings manually and also both A-XMP Profile 1 and 2 still no luck, so I flashed 1.5 back and down clocked to 2933Mhz instead.. anyways, not a big issue , I'll just wait a little longer.

[darkhawk]

What's your issue? I mean, your post provides no information to even begin trying to help.

Others have gotten their issues worked out with the beta, but posts like this just don't help things at all.

I have the Corsair vengeance lpx 2x4gb using the beta bios. If I choose xmp2 3000mhz it's changes to 2400mhz and same for xmp1.

What memory? That description doesn't tell me what it is, only that you have corsair vengeance LPX ram, 2 x4gb sticks. Doesn't tell me the model #, what speed it is rated for from Corsair, no part number.

And what happens? You select XMP1, reboot, and it shows 2400 MHz?
Or does it try to boot a few times using those settings, fails, and defaults back to 2133? 
What exactly happens? We can't really try and help with small little bits of information. Explain in detail what is happening.

They both boot with its incorrect, I still have that problem explained on the other post. Should I do manual timings I'm still new to this I'm not sure about the settings to out in.

Ok I've flashes the bios again, xmp1 works, xmp2 is at 2933mhz.

So I flashed back to the latest stable bios for tomahawk (1.50), set DRAM voltage to 1.4 and NB (SoC) voltage to 1.1, now I'm posting at 3200 more often than not. It's not perfect but it's an improvement over the 1.62 beta.

The beta works fine....

Most likely flashing it again (a 2nd time) would have resolved the issue. As it has for many others. See above.

Well I just tested this. Restored optimized default settings and flashed 1.62 back to back. Still couldn't POST at 3200. Flashed back to 1.50, can now POST at 3200. I know the beta bios works well for most, just not in my particular case.
