Think I may have a made a mistake picking out the RAM modules for my new build. I recently read an article saying it was possible to put 64gb of RAM on the X99-Deluxe, because I do a lot of large image/video processing and also some pretty huge data set processing using R/Python, I decided to go for it and grab two Corsair Vengeance LPX 32gb kits. This gives me 4 sticks at 16gb each. I built the new PC on the X99-Deluxe and fired it up. Everything is gravy except that the BIOS and windows 10 both are only seeing 32gb of RAM. I'm pretty new to building my own PCs, did I miss something important here? I did some research before the build and ran across numerous forums with a lot of people saying "just because they were the same kit doesn't mean the RAM will work together, etc." but, I though that the quad channel architecture on the MB was supposed to eliminate this issue. Any help appreciated!

With further testing and using your suggestion it seems that the computer will not boot at all unless two sticks are present in slots B1 & B2. Using a single stick in any one slot makes the computer seem to be on for moment but then the fans turn off and everything but the mother boards lights turn off.

Inspected the pins on the MB and the contacts on the cpu and everything looked fine. Then... found the "memok" button on the mother board and watched a youtube video on that. After using the "memok" button everything booted correctly and all 64gb were recognized! Thanks for troubleshooting with me!
