When I try to run my DDR4 at the rated/tested speed of 3200 the motherboard no longer sees my PCIe SSD (only drive I have installed and has Windows 10 on it). It's the same when I try XMP or manually setting the timings and voltage to 1.35. Everything works fine if the RAM runs at standard stock speed of 2133.
I have the following:
Everything is running stock, I'm just trying to run RAM at rated speeds. I also tested OC genie and was able to get 4.4 easily. I ran Prime 95 and HCI Memtest for 12+ hours stock. If I try any other RAM speed that's not 2133, the bios fails to see the PCIe SSD. However, when it goes back to stock it sees it just fine.
About this situation with your SSD and RAM, we would like to suggest a few steps:
-Could you please try removing one of the video cards and overclock the RAM and test?
-Once you have one video card out, please try the SSD in different ports.
We checked there is an utility in the MSI* website, the utility is http://download.msi.com/uti_exe/msi_ramdisk.zip RAM Disk, you may want to try it as well.
We will be waiting for your response, please keep in mind we recommend to contact MSI* about any change on BIOS as we do know the SSD works fine.
We are very glad to know the situation was fixed with this beta BIOS version. We will close the case, but remember that in case you need further assistance we are here to help.
