Ryzen RAM Isuue

[Judd]

I have had my computer for about a month now and my single 8gb RAM stick was set to 2667mhz, with 18 CAS latency. Now, I added another stick of the same memory and now I have problems. So first I can only reach 2400mhz with the same timings, but now, whenever I restart my computer the 2 EZ Debug LEDs that are for DRAM and CPU are on, which requires the PC to restart, fail to post, then restart, fail to post, then restart into windows with the 2133mhz RAM with the same timings. So I though the 2400mhz was unstable. So I changed the RAM to 2133mhz in the BIOS and it booted fine. Then I restarted it and the same restart and fail cycle came on. The problem never occurred with only 1 DIMM and it was able to do 2667mhz. Right now I am going to try the new stick of RAM by itself and see what happens. Here are my specs so you can know; MSI B350 Gaming Plus Motherboard, Ryzen 3 1300X at 4ghz @1.375v, and the RAM is 1x8gb G.Skill 2800mhz Ripjaws V with 2 sticks installed. Thanks for any help you can give.

So I just tested it with my new stick only and it fails to even post. Now I’m trying my old stick. The old stick posts but it still gives me the EZ Debug LEDs.

Remember that Ryzen timing changes depending on the RAM configuration:

Now with both sticks in it will post but when I restart the computer it will fail to post and just give me the 2 DRAM and CPU error leds.

I am fine with the 2133mhz speeds but what I’m not fine with is it failing to post every single time.

This says I should be getting 2667.

I now switched the ram sticks to the opposite side and now it posts.but when I restart it it goes into the restart fail cycle

Snap a pic of how you have them installed.

And now when I restart it at 2133mhz it fails to post till it cycles through and loads defaults. Even when it is set to defaults it will it will not post.

Looks good to me. 

I assume this is already what you're doing but, but this is what I would do:

1. Go back to the single stick configuration that was working.
2. Go into BIOS and change back to all default settings, including CAS
3. See if it posts with 1 stick
4. Try including another stick. See if it posts.

What G.Skill model is that?

G.Skill 1x8gb RipJaws V 2800mhz. If that is what you need

It posts this way at defaults. When I restart it it gives me the the two error leds and it fails to post after restart.

That's so odd. Even with CAS at 15?

Yeah. At defaults. When I test each one individually they both work. Together they do not.

Now in task manager it shows 2 DiMMs used but only 8gb useable and 8gb in reserve. In the BIOS it only shows 8gb.

Check that you have the latest BIOS for your board installed - 7A34vM4. Also, new AMD chipset drivers (ver. 17.40) were released a couple of weeks ago, which may be worth installing as well.
