Just put a classified 5930k + 2 x 6gb EVGA 780 system together in a lian li case.  I haven't played around too much (haven't touched ring voltage ring ratio vsa voltage) but I'm getting stable 6x 4.74GHz at 101 x 47 1.35v adaptive, vdroop disabled, vpro/virtualization disabled, all cstates on, HT on. 
 
I have booted and can do most desktop tasks at 4.8ghz which makes me think I may be able to stabilize that but haven't gotten 4.8 to pass intelburntest xtreme mode, booted at 6x 4.95GHz and a single core up to 5.2Ghz.
 
So that's my story what kind of numbers are you seeing on your EVGA X99s please post configuration details. 
 
Thanks!
 
  

I'm at bios v 1.06 (edit: meant 1.16), Ram timings are attached.  I'm still trying to screen capture from bios I'm not used to the VSA and Ring Ratio.  Here's where I'm at for 24/7: 4.74Ghz 2422.6, 1:18 FSB:DRAM, 16 16 16 2t.  at 4.74 this thing is solid and doesn't take much voltage.   I got 4 more sticks today does running 8 sticks doesn't degrade OC potential?

So I did have a bit of trouble going to 8 sticks stable at 4.74 1.35v but nothing fatal: I had to go back set everything to XMP 1 and copy all of the ram entries across both banks eliminating auto RAM (auto timings resulted in instability at 4.74) timing settings, then I had to go back and manually set the CPU multi as XMP put it to 37.    Also had to increase voltage to ~1.38 to remain stable with 8 sticks.
 
As for IBT I use Xtreme Stress mode, right click on start and check xtreme stress mode.  I do see some point in other stress tests later but I'd like to thrash a mechanical drive and not an SSD with lindata, also like to give my CPUs time to break in a bit before running them hard for hours.  Will read the thread.
