i haven't seen any posts about the x99 sli. So im not sure if others are having my same issues or if my issues are somehow lumped into all the others as the same or similar. I recently purchased a new x99 sli from new egg. It started up ok into bios the first few times but never went beyond that and now i cant even get that far. Things I've tried. First off with nothing but mobo, processor, video card, power supply and one stick of ram (in manual provided slot). I push button and everything seems fine for about 5 secs then i get an endless set of short beeps for around 15 secs until auto shut down and auto reboot to the same. Every thing ive found about beep codes say its the power supply unit faliure. So I tried a 1200 watt and got the same thing. I tried all four different sticks as stand alone in the first spot and get the same thing. From what ive read it seems to be one of two things, bent pins which i checked and all seem ok or i need to flash the bios. Problem is that when i remove all sticks of ram i get an endless prepost boot loop so my flash drive never gets read. I also tried to flash the bios with one stick in and it goes back to the post boot loop. I did try to boot with out the video card and with a different one and still get the post boot loop. I dont have a second processor or a fifth stick of ddr4 laying around. I'm sure ive forgotten some of the things ive tried but i think this is a good starting point.
Machine specs
Motherboard = X99-SLI
VGA = Nvidia Gforce GTX 760
CPU = Intel i7-5820k lga2011v3
Power supply = Black Widow TR2 RX 850W
RAMM = G.Skill DDR4 3200 CL 16-16-16-36 1.35v

os = windows 7 latest updates
hd = ssd plus 6x 256 gb
P.S. something else i tried was booting with and without any or all and all combinations of the hard drive all leading to the endless post boot loop. Ive also tried to boot up with windows 7 disk in and the gigabyte driver disks in and get the post boot loop with endless short beeps till reboot.
Any suggestions would be very appreciated. If theres anything i left out please feel free to ask.
I had issues with this motherboard, my issue was that the board would refuse to boot, tried everthing in the end I received a replacement, the replacement works but I had problems with the bios not liking my Ram which is on the approved Ram list and the bios crashing, updated the bios to F2a Beta which allows the Ram to work but not in XMP profile otherwise I get constant BSOD memory issues, there is a new bios just come out a day or so ago F2b Beta but i'm not willing to update to that version yet as I'm not sure of the underlying faults reported as of yet. Apart from it being a good quality board, I think that Gigabyte should step up the mark on the Bios issues, and should only release a motherboard with a fully tested bios with fully tested compatable hardware which I don't belive they have done which is why I'm having problems with the so called approved and tested compatible Ram for this board.
As advice I would recommend returning the motherboard, with a new replacement before you install check the motherboard all over for bent pins scratches and bad solder and to make sure you do a fresh/clean installation of windows otherwise you may have compatibilty issues, install all latest drivers from Gigabyte's website.
