Uninstalled and reinstalled my network drivers. After 2nd reboot I decided that I would like to see what my new CLC 280 was running on stock clocks. Dropped the Manual Clocks back to 100 Blck Automatic Multiplier Save Reboot, post code 68. 
 
I previously had this thread, to give a little background. Ram ended up being upgraded to 64gb of corsair vengence lpx 2666. 2 kits of 32 which worked well until this point.

Any thoughts on post code 68.
Reached the the back CMOS reset hit that (nada) 68 again
Change bios 68 reset cmos on that bios 68
bios 2 same
bios 3 same
Test each ram stick in slot 1 68 each time.
 
I have had the motherboard powered down with the cmos battery out and every bios comes to the same result, No memory codes posting, regular post code cycle till. 78 then hangs on 68....
 
5280K was tested on the new boards by the way and still comes to memory error codes B0 19. Separate project to press on later.
 
Thanks for looking, appreciate all the feedback. Need my gaming PC BACK next 4 days off!

    One fix that has worked in the past for someone else is:  "Clear the Cmos by pressing the little red button above the Power button on the board." Worth a try.

    Yeah I know about that. I cleared CMOS on all three bios and still posting 68 on each reset.

    An X99 POST Code 68 is PCI host bridge initialization..You can search the net and get some hits for possible fixes..You can do a Forum Search (top-right of this page) for POST Code 68 and also get some hits for possible fixes..The good thing is that your X99 Classified has a removeable BIOS chip that can be replaced if needed, and EVGA will send you one (with the latest BIOS) for a fee if you contact them.
