I'm thinking he has his two sticks residing in the A _or_ B slots, meaning Single Channel config.

I seem to remember experiencing the same symptoms once till I discovered the clients kid rearranged the memory.

Too, the diff of loading a single channel to 2133 and fine, 2400 not so, the speed diff could be just enough to be causing an IMC issue

That's true about the FX-9590 of course, but the OP is asking why does he experience slow gaming performance when the memory is set to 2400, when it is fine at 2133.

The question is, is that caused by memory instability at 2400, or something else?

First, any memory speed above 1600 is a memory over clock, and not guaranteed to work. Please check the memory specifications for your board on this page:

http://www.asrock.com/mb/AMD/990FX%20Extreme9/?cat=Specifications

Your board's memory support list contains additional information about memory speeds:

http://www.asrock.com/mb/AMD/990FX%20Extreme9/?cat=Memory

The memory speed you can over clock to depends upon the memory model you have, what the timings are set to, and the memory voltage value. We don't even know what model of memory you are using.
