Aurora R9, Corsair LPX, XMP2 Profile doesn't exist

Question

I have Aurora R9 and having issue with RAM upgrade. I tried Crucial Ballistix 32GB (16X2) and that RAM is very unstable. The computer would sometime boot, sometimes not and within 10 minutes or so after logging in to windows, it would freeze. Running it on XMP1 (there is no XMP2 profile as well) Returned and getting Corsair LPX 32GB (16X2) and this would run MUCH more stable on XMP1 profile @3200Mhz but unfortunately, it does freeze too after several hours. I like to run this at XMP2 profile but there is nothing but XMP1 and disabled (if disabled, the RAM would run at 2133Mhz but stable). Corsair stated this memory have XMP2 profile, what gives? Running latest BIOS 1.0.9. XMP Disabled XMP1

I resolved this by troubleshooting it with Corsair support, they sent me a replacement ram (same model but version 5 instead 3, also JDEC showing Samsung chips instead of Micron). This stick run stable at XMP1 profile.

This forum post has a little more information about XMP2.

Also, with that specific RAM, the second XMP profile requires increasing the voltage and, per Corsair, that RAM is not officially supported or guaranteed by Corsair to work when the second XMP profile selected. It seems like you may fall under that category.

Per CORSAIR:

"The first profile, then, is officially supported, while the second is not and instead offers a baseline of what the memory should be able to achieve."

I went to their memory selector and this RAM listed, but their memory selector are showing broad results...not that great. Which corsair memory would work on R9?
