X370 Gaming K4

I have this board and compared to the gigabyte ax370 board the memory seems to run at one speed lower on the asrock gaming k4 Me and my friend have various sets of ram and we have tried them on each others board.

If you check the Memory QVL list for your board, or any ASRock Ryzen board, we will find this:

Note1: Each RAM whose frequency is 3000 will downgrade to 2933 with Fatal1ty X370 Gaming K4.
Note2: Each RAM whose frequency is 2800 will downgrade to 2666 with Fatal1ty X370 Gaming K4.

As wardog said, these are examples of the "memory dividers" that a Ryzen system does not support. Apparently, the "downgrade" to the slightly lower memory speed is not happening automatically, or another memory problem is the reason you cannot run your memory near 3000. Ryzen memory compatibility is probably the number one issue we are seeing so far.

I just read about a tweak for getting memory to work on Ryzen systems that I'll describe, that I cannot guarantee will work but will offer it if you feel like trying it out.

First, stay with a maximum memory speed of 2666/2667, which is the maximum, non-OC memory speed for a Ryzen processor. Do not apply the XMP profile in the DRAM Configuration screen. Now the fun part...

The default settings for memory options is of course, Auto. The tweak I read about said to set each and every memory option manually, from the Auto setting. If you have a memory option highlighted and set to Auto, if you press the '+' key once, a numeric value will appear. While that should be the Auto value, apparently using the numeric value makes a difference.

Doing this to the many memory options is a lot of work, and may result in nothing. A review of Ryzen I read described this as the method used to get their memory to 2666. Again, I cannot guarantee it will work for you, so please don't hate me too much if you try this, and it fails.

Always ALWAYS know the Specs of the component you're about to change. I can't say this enough. Blindly changing away from Spec is like shooting clay pigeons with both eyes covered.

I'm not sure the 1E is NOT related yet your board seemingly is running w/o issue(minus the 1E).

So you're aware, Ryzen isn't cognizant of 3000 and 3400 dividers. That, w/o me having the same get up you do, leaves some suspicion that it may be related.


That leaves me to ask you if this kit is in fact running at 3000?? Or maybe a tad lower or higher?

May I ask what memory kit?
