DDR3 rated 1866Mhz for Sabertooth X79

[GrayHouse2013]

Have a new Sabertooth X79 with i7-4930K, looking to see if anyone has the same and if so, do you have a 1866Mhz quad channel set of RAM that is working at XMP setting or manual setting for 1866Mhz, without any other tweak's to BIOS (4502 or 4608 BIOS)?

If so, what brand and model number?

Looks like Corsair and G.Skill have good DDR3 sets that are working well recently with this base setup.
I have ended up with Corsair Vengeance 4x8GB (CMZ32GX3M4X1866C10R) / timings: 10-11-10-30, in my build and mystery beeps/tones in Win8.1 running XMP or Manual 1866Mhz seem to be gone now (knock on wood).
