Problem with ram 3200mhz with x470

1 : Anonymous2021/03/23 15:57 ID: mbhvgg

Whats up guys!

could you help me with the question?

my config: ryzen 3400g mobo x470 biostar gtn ram 2x8gb 3200mhz trident z (running only 2133)


I used a ryzen 7 1700 and the rest of the config the same, I always tried to activate the xmp to run the ram at 3200mhz that would be native, the mobo supports up to 3200, but I never got it.

I got rid of the ryzen 7 1700 and bought a 3400g recently, as it is an apu, the more mhz on the ram is better.

However the xmp does not work the same way whenever the pc goes back to 2133 in the first attempt to activate the xmp the pc crash windows and had to format (never seen it in my life).

but I noticed after a time of use that sometimes when turning it off it just does not turn off, it just turns off the screen and the mouse / keyboard, making it impossible to restart or turn off the cabinet button, just unplugging it.

And sometimes when you turn it on, it makes this same problem of turning off the video and the mouse / keyboard, being necessary to unplug it.

Has anyone ever experienced this? this is killing me!

Thank you all!

3400G only supports DRR4-2933. Anything above that needs tweaking to work, if at all.

I try 2933 and the same problem, Works only in 2133

Since the 2200g and other G models launched... 3200mhz has always been obtainable for me, and i've built a shit load of 2000/3000 g series systems. Also a month after the ryzen 1000's launched, every machine i built used 3200mhz memory out of the box just fine. It's a unfortunate case of people with arguably poor boards most of the time rather than the claimed "ryzen 1000 was just really bad with memory", no that wasn't the case, it was people using pretty terrible modules or often poor boards at the time.

Pretty much anyone that micron based modules is going to have good luck. If it's hynix, or mostly anything other, i've had to regulate it to intel systems exclusively. Corsair often uses garbage ICs therefore i've told people to avoid corsair if they want to keep their hair, as even at 2133mhz fail safe timings, that shit will constantly eat dirt, maybe not daily, maybe not even weekly, but i've NEVER had a stable set of corsair memory in any ryzen build ever.

I find it very strange, since the ram is native 3200mhz and the motherboard accepts 3200, I tried the test with 2933 without success too. I think it may be something related to outdated motherboard bios, I verified that it is a 2019 build.

I'm just afraid to update and stop accepting Zen+. Can this happen, with the last bios update??

Then you were exceptionally lucky. The first gen mem controller struggled to reach 3200 at all. It could, but it was exceedingly rare that you could just set it and go; nearly always required tweaked settings and usually a little extra voltage.. Successive mem controllers improved that rapidly, but your claimed experience with first gen is atypical, to say the least.

Have you updated the BIOS to something recent?

For that combination the minimum is AGESA ComboAM4 PI and I would recommend the latest of ComboAM4 available.

Also 3400G is in line with 2000 series without iGPU which is a hit or miss with RAM. You basically need a Single-Rank type of RAM for it to work without much effort or else the base freq. will 2400MHz max. Otherwise the system will find whatever is the most stable for your modules below that and that is programmed in the SPD, in your case the 2133Mhz.

G.Skill early era is also not great for AMD. Hence they've created the NEOs for compatibility reasons.

You can try to put your settings in the Ryzen DRAM Calculator and type them manually in the BIOS. That's how I got away with it for years with a 2700X.

Edit: I have a 2400G in a AB350 working at 3200MHz with the XMP profile but it's like I said, single-rank DIMMs.

I found similar interesting discussion at tpu forumddr4 3200 issues

I have a few 3200g’s and most will run 3200 no problem with the odd one that just can’t seem to manage it. As the memory controller is on the cpu I expect there’s nothing wrong with the board/ram..

Update bios and if that doesn't help, perhaps increase voltage slightly on the ram and see if that helps stability.

RAM compatibility and stability can only be improved by AMD through AGESA updates. These come inside of BIOS updates. Update your BIOS.

Check your ram slots in your motherboard manual. Slot 1/3 may not support the speed you want and slot 2/4 will

Not sure if I can be of some help, but here's an issue I had a week ago:

I had a BIOSTAR X370GTN w/ 1700 + 3200 CL14 RAM. Worked fine without any problems.

I upgraded that system to a new motherboard and CPU, so now I had a spare motherboard laying around. I decided to build a second system with it, so I bought a 3200G. I didn't have spare RAM, so I also ordered a pair of 4GB G.Skill Ripjaws V 3200 CL16 sticks. I figured since it's the same brand RAM, everything should work. Big mistake. When I put everything together the system wouldn't even boot. I put the 1700 back in, and it booted. Made sure that my BIOS was up to date, and tried 3200G again. Didn't work. After further troubleshooting, I tried my CL14, and that RAM worked, but I needed it for the newer system, so I ordered a set of Corsair LPX 3200 CL16 RAM. Put it into the BIOSTAR board, and it booted up without a problem. Went into the BIOS and turned on XMP 3200. The system now works without issues. Conclusion: The G.Skill CL16 RAM was most likely the issue when combined with the board and 3200G.

I had an issue with my 2600x blue-screening with just XMP profile being turned on my 3200MHz Vengeance RAM, so try using a Ryzen RAM calculator, it might help. (guide by Hardware Unboxed)

P.S. Also, try updating your BIOS, it also might help too.
