I've noticed that when I install a new BIOS I get the full screen logo showing up properly at POST but after I switch to AHCI mode and make a number of other changes I don't ever see that GIGABYTE logo screen again.
The first thing I see is the AHCI device listing that is why I suspect the AHCI mode is the culprit.
Some of the other changes I make are: disable all the options I don't use (2nd LAN, USB 3.0, eSATA, GSATA3.0, Parallel Port, Serial Port), set my default video detect to PEG2, power up on Mouse (which doesn't seem to work), floppy drive to None and disable the third boot device so its just HD and then CDROM.
Are you disabling "Full Screen Logo"? This is the setting that "should" disable/enable the GIGABYTE image.
If you are leaving that enabled, yet it still disappears you will need to manually go through your changes one by one until you find the setting that is also disabling it.
Sorry for the delay, I believe the issue is when you start disabling the integrated peripherals you don't use, then the POST time is reduced and the full-screen logo doesn't have time to display.
When you start/restart the monitor is initially in sleep mode, by the time the monitor wakes up from sleep mode the logo is gone.
I tested by adjusting the settings one at a time as you suggested, the ones that make the biggest difference are the IDE Controller and the ESATA and GSATA. Just disabling the IDE controller cuts about 3-4 seconds off the POST time and you only see the logo for 2 seconds instead of 5+ seconds. Once the ESATA and GSATA and serial/parallel are disabled then the logo never shows.
I find with this BIOS, when you are in BIOS looking at the info, the USB's are turning on and off. I was watching my Logitech USB Microphone green light on for 1 sec off for 1 sec. Never seen this before. Another pain I find is if you choose shutdown in windows it powers down ok, but when you go to power it up again it flicks on then off in half a second then stays off.
As i PM'd you on xs forums, the GIGA EP45T USB3P is having issues holding DDR3 at 2000mhz, i have 2 sets of Gskill
2x2 ECO 1600 7-8-7-24
2x2 PIS 2000 6-9-6-24
both will do 1600 perfect on rated timmings, but specially the last that is my call is rated 2000 at those timmings and XPS profile but not way of making boot at that...i can go 2000 on CL9 kinda stable and CL8 and starts getting hard
Also for 2000 if you set 2T on bios always auto set 1T...
Im on 4500mhx X3380 at 1,392vcore Linx stable 1600 CL6 PL8 Standard
Just reporting this as maybe is some memory compat issue on bios, i've been working like 2 weeks on this and stil i cant get 2000 fully stable
Using bios F2D i dont know if worth flashing to the first bios F1
Cheers

This is making me furious. Gigabyte seems to be paying attention to every other 790X board except for mine (790XT-UD4P).
I've been waiting weeks for a new BIOS to fix my northbridge & RAM overclocking problems (with a 1055T, which I did at least manage to get to 4Ghz) that I get on both F8C and the unofficial F8D...
xd_1771,
if you have serious issue,please send request to: Motherboard - GIGABYTE
Usually they will send you new beta BIOS.
Btw,
updated with new beta BIOS:
secondary bios maintains a copy of 10a caring the old Achi driver. Don't know how to flash them both bioses. x. can set the +0.5 multi now but no miracles here, it was tempting to unlock e8500 for a moment there. stable so far.
