x370 K4 eol

The Taichi gets my vote too, I love mine. I also have a Gaming K4 and it does a great job too, it just doesn't have the overkill power design and is the wrong color scheme for my black, white and blue build. 

Gamming X is not a same as K4.
X - more cheap.
May be more cheap even that killer sli.

EOL simply means they are no longer in production but support will continue, just like any other board.

Well, this thread was originally asking about the status of the Fatal1ty X370 Gaming K4, not specifically about memory over clocking.  What help did that person receive, did they get their memory working at 3200, or what?

Then the question was, will the X370 K4 receive 3200+ memory support. Regardless of the memory model, as long as it is rated at least to 3200, it will work at 3200? How can we know if that is possible, given all the variables involved? Memory over clocks are guaranteed? We both know they aren't.

After two AGESA updates, my G.SKILL FlareX 3200 memory can only run stable at 2933 on my X370 Killer SLI/ac board. I'm at the point where I'm trying different ODT values that I found others using, but that is only valid for my model of memory.

We have no idea what the OP has tried to do at this point about his memory OC, or how high he is at now. If it was simple to do, and guaranteed, we would describe how to do it. We can find his general model number in the Rymem list, but the maximum speed is ~2933, but we don't know if he has the 539 version.

Agesa is not the be all end all for ram. example. one user pulled his CPU and ram out a K4 and put in a Gaming X with same agesa version and was able to get 3200mhz. The arguments that the cpu's memory controller is the culprit does not hold water.

Well... Ok, and this user was absolutely certain that everything else, including CPU OC, VCore, SOC, DRAM, etc, voltages were identical, as well as using the absolutely identical memory timings? What was his max memory speed in the other board, 2933?

I'm NOT saying that is impossible! It is possible, due to other factors. Such as, the quality of the DIMM slots for example, or the routing of the circuit traces between the DIMM slot and CPU socket. Other boards don't have the same SOC voltage settings, or the same VRM design for the SOC voltage. Those last two things do NOT apply in your example, but the others might.

The memory controller situation is not what happened in your example. The memory controller's potential to OC can be different between different examples of the same CPU model. We can only guess that the IMC is not that good when a memory OC fails. Move the CPU to another board, and it can reach a higher memory OC. That seems to show the IMC is better than we thought, and is the only way we have to test it. Does that prove the other board is better? At the level of access to technical details that we as users have, unfortunately the answer is yes.

Did you notice that the specs for the Fatal1ty X370 Gaming K4 has the maximum memory OC as 2933? For the X370 Killer SLI, it is 3200.

Consider attempting to answer the question, "My 3200 speed memory only reaches 2933, what is wrong?". That's all you have to work with. The question is not what can I possibly do to reach a higher memory OC, but what is the fix that will run it at 3200? Meaning it is a given that it will run at 3200, and all that is needed is for me to tell them what to do.
