OK - I'm not sure if I understand the numbering system you are referring to. You have an ASUS X99-A, correct? In the user guide, they are not numbered 1, 2, 3, 4, 5, 6, 7, 8. See below:

First of all, I would not do your OSX install with all 4 DIMMS installed. Only install 2 as indicated by the illustration on the left below:

Once you have your build completed successfully, then install the remaining DIMMS as illustrated on the right in the image above.
Have you gone to the ASUS Web site and gotten the latest UEFI BIOS and reflashed your motherboard? When I got my X99-Deluxe, there had been 2 newer versions of the UEFI released. There may even be a new BIOS released in the next couple weeks that will fix the problem with having to boot from USB key. Stay tuned...
I don't think you have damaged your memory - otherwise during POST, you would have received an error about your RAM.
Please - make sure you have followed the instructions EXACTLY as shown in the original post, including kernel patch on UniBeast, plus copying patched kernel over to your Mavericks install (if you even get that far) and of course adding the
apci=0x2000 to your org.chameleon.boot.plist.
BTW, that is an EXTREMELY high-end video card you have. Did you also realize that special drivers are required for your card? Please check the Buyer's Guide > Alternate Graphics Card, and review the information at the top of the section, then follow the link.
With this system & a graphics card like that, what kind of power supply do you have and how many watts?
