New Build: Asrock AB350 pro4 - Freezing in Win10

What's most important is to have a stable computer and it's starting to sound as if it wont happen with this motherboard.

Both before and after the Bios update this new build randomly locks up.  Like a frozen screen, no blue screen, no reboot, just stuck. I?�ve not witnessed this happen in a computer for years... The freeze seems to happen when I?�m downloading or transferring files more often than not. Additionally, my memory will only clock to 2133, and not the prescribed 3000 with either XMP settings or manual configuration. I installed the memory in the 2nd and 4th slot counting away from the CPU. I understand that the QVL list includes a similar memory module, though it?�s not exact.  I just read that D stands for 2 sticks and Q stands for 4.  So would that mean i cannot run at 3000Mhz without 4 sticks of this memory? QVL Listed: F4-3000C15Q-16GRR Used: F4-3000C15D-16GVKB Without getting into the "new platform, issues, etc.." would anyone like to provide some advice as to how I should approach this situation.

"... without getting into platform issues...", sorry I cannot ignore reality. As long as you are aware they exist, particularly with Ryzen memory compatibility, I'll mention as few as possible.

Are you asking in general why you are experiencing freezes, and how to diagnose it? Or do you believe it is memory related?

QVL Listed: F4-3000C15Q-16GRR. That's a Ripjaws 4 model:

Used: F4-3000C15D-16GVKB. That's a Ripjaws 5 model:

The Q and the D are not of significance here. That they are different models is. The Ripjaws 4 model is a quad channel kit designed for Intel X99 boards and HEDT processors that support four channels of memory. No requirement to use four DIMMs.

It is coincidence and luck that the F4-3000C15Q-16GRR model apparently works with Ryzen, but to what degree (speed) I don't know. The F4-3000C15D-16GVKB Ripjaws 5 model is designed for Intel Z170 and Z270 systems.

Also, the Ryzen processor's memory controller's memory dividers do not support a DDR4 memory speed of 3000 according to AMD. The closest supported speed is 2933, which should be used with 3000 speed memory, as is noted in the QVL list.

The XMP profiles with any DDR4 memory designed for Intel systems, as the two models above are, won't work with Ryzen. Setting the timings, speed, and DRAM voltage manually is the correct method.

The best description about using DDR4 memory not designed for a Ryzen system that I've read is this: "... it's a crap-shoot." I agree, given what I have read about one pre-Ryzen DDR4 model working with Ryzen, and other pre-Ryzen models not working with Ryzen. We've seen examples of the "same model" of memory that have different memory chips in them, some Samsung, some Hynix.

As a moderator, I should tell users what will work, which is why I go with the board's QVL list, or what models are recommended by the memory manufacture. G.SKILL suggests the models on this page for your board (sorry for the text link, some URLs fail with the forum's link tool):

I've been told I'm wrong to say memory models not included in either list should be avoided, because some people on the Internet have gotten them to work with their Ryzen system. The problem is, other users cannot get the same memory model to work. I can't take that chance with their money and time.

Are you installing all the basic drivers for your board yourself? Such as from the board's disk, or by downloading drivers from your board's Download page?

Windows 10 update will install drivers automatically at any time, video drivers being a good example of that. My video driver was randomly updated while I was writing a forum post. My dual monitor setup suddenly began going dark on both monitors, and only one came back on. The default video driver and Windows Display settings were reset. A video driver installation done by a user always ends with a request to restart the PC. That did not happen when Windows installed a video driver, although it was still needed. I realized what happened and restarted the PC, but who knows what other Windows driver installations will do?

I'm taking the memory back today. i've ordered F4-3200C15D-16GTZKW.
