There's a 2x multiplier involved. DDR stands for double data rate, so you have to multiply the base number by two in order to see what your RAM is actually running at. Based on what CPU-Z is stating, your memory is technically running at 2793.4 MHz. It's a little shy of 2933 but that could be based on timings and voltage.
For example, I only have 2666 MHz sticks in my R7. Here's what CPU-Z is showing me:
BTW, maybe you can help me. Since my RAM is only 2666, XMP in the BIOS is grayed out. I assume the system will enable the XMP option once faster memory is inserted?
I would imagine this being the case. I am not too tech savvy on this, but something I recently have been researching. Maybe you have an older BIOS version?
I'm on the latest version 1.0.17. I have a feeling that system predetermines RAM clock speed and if its below a certain threshold, leaves XMP disabled.

Thats really appreciated. Thank you for the info on this and glad to know I am running at full speed and XMP is working.
Thanks

No worries John. Glad to help.

I really hate the Aurora BIOS...
