HELP configuring Ryzen

[Virgule]

Hello,

 

As the title states, I need help configuring a Ryzen build. My problems are that only 32 GB are detected and that I have memory instability.

 

First of all, here are my specs :

 

Ryzen 1800X

MSI X370 Gaming Pro Carbon (Latest 7A32v13 April 11th BIOS)

CORSAIR Vengeance LED 64GB (4 x 16GB) DDR4 3000 (CMU64GX4M4C3000C15)

NZXT X52

Samsung 960 Evo

Corsair RM850i

...

 

Here are my BIOS settings :

Just a side note, all DIMM information were the same so I just posted DIMMA1. As you can see, the memory sticks are detected, however the system memory states only 32GB. Also, when I apply these settings, the system will run the 5 memory auto retries, then turn on. I've tried with 2133MHz and it does the same 5 failed attempts.

 

Can anyone help me identify the improper settings in order to get all 64GB detected as system memory and hopefully try a higher (say 2933) memory frequency ?

 

NB: Not looking at CPU overclocking right now, will take a run at it after this thing is rock stable.

 

Thanks

Try turning A-XMP off instead of Profile 1 and setting the speed manually to 2133 MHz, with RAM timings set to Auto under "Advanced DRAM configuration".

Will try that and report back in a few minutes.

Yep I have that board and although I only have 32gb of ram I cannot get it to run with A-XMP on

So I've tried with A-XMP OFF and at 2133 with auto DRAM settings and I still get 5 reboot retries and 32 GB detected.

Maybe try the memory at 1866 MHz?  I think that's as low as it can go.

What does that prove if it works ?

Can you share your BIOS settings and specs please ?

It'll prove it can boot at all.

 

The other thing to try is troubleshooting the memory sticks themselves.  If only 32 GB are detected we need to figure out which sticks are working and which ones aren't being detected.  First I would suggest putting each stick one at a time into slot DIMMA2 and making sure 16 GB is detected each time.  Then I would try two sticks in DIMMA2 and DIMMB2.  Then the same two (if they worked) in DIMMA2 and DIMMA1.  Then again in DIMMB2 and B1.  We want to figure out if any of the sticks are dead, or if any of the sockets are dead.  

 

 

Also which BIOS version are you running?

It still does the 5 boot retries and then boots. 32GB are detected. However, when I put A-XMP back on at 1866, it boots without 5 retries, still 32 GB are detected.

If the Memory-Z info is there (see photos in OP) for all DIMMS, doesn't that mean that both slots and DIMMS are fine ?

Ok so get this.

 

I tried every stick in slot A2 and every configuration shows 16GB except one stick, which boots but I don't get any video signal. So I would guess I have a faulty memory stick.

 

After that, I've tried two stick (which I knew were working based on my previous test) in slots A2 and B2 and it worked. I got signal and detected system memory was 32GB. I then tried A2 and B1 and got no video signal after boot. I thought that this was normal since the recommended 2 DIMM configuration was A2 and B2, not A2 and B1. I still tried A2 and A1 and got signal and detected system memory was 32GB.

 

So it seems as though I have a faulty DIMM and a faulty B1 slot on my motherboard. That seems highly improbable. Also, I could detect Memory-Z info for the B1 slot and for all DIMMs. Is that probable even with faulty DIMMs/slots ?

What happens if you fill every slot except B1 with the three sticks that seem to work fine?  

 

I would try booting using just the B1 slot with a single stick that works as well.  Anything that can narrow down if the stick or slot is the culprit.

I haven't tried that but I've done that with A2 and one stick doesn't boot so that means pretty much with 100% confidence that one stick is faulty.

I haven't tried that but I've done A2-B2, A2-A1 and A2-B1 with pairs of sticks that work and only A2-B1 doesn't boot. I guess that this means with 100% confidence as well that B1 is a faulty DIMM slots. Is my reasoning incomplete ?

 

I also did the same batch of tests again with a BIOS clear between each different configuration and I get the same results.

It does seem like one stick and one slot is dead.  I wonder if the stick was killed by the slot though?  Or if it's just really bad luck.  Perhaps B1 not booting could just be how the motherboard works though?  They definitely strongly recommend A2-B2 so maybe it's normal for the B1 to just not work on its own?  I would perhaps suggest contacting MSI directly about it.  

 

I would also Try A2B2A1 to see if it can detect more than 32 GB.
