You can probably mix them, but understand that any combination will only run at the speed of the weakest (slowest) stick. Here's what you have:

Kingston = DDR3-1333 @ 667MHz
Crucial = DDR3-1866 @ 933MHz
Corsair = DDR3-1600 @ 800MHz

The Kingston is already bottle-necking your system because it's only running at 667MHz. And if it's by itself in single channel mode, it's causing a further bottleneck. At the very least, you should be running a matched pair of DDR3-1600. A matched pair of DDR3-1866 would be even better. Timings aren't all that important because they can be manually configured in the BIOS. And to a certain extent, so can the frequencies.

Didn't you ask about this before?

If you visit the crucial.com website and let it scan (it's safe) your system they will tell you what you can use on that motherboard...

I seem to recall they will usually offer more than one brand for a given RAM; and Kingston is one (usually) and then their own branded RAM...?

If the specs. are the same then from my own (albeit limited) experience yes you can mix makes...

Micron and Kingston I have seen installed in the same system and no problems; similarly Crucial and Fujitsu.

But they must be identical in specification...
