Hello,
I see that there is a F9 version of the BIOS for GA-Z87X-UD3H, but it says "(
Note) Please use the efiflash.exe included in the zip file to update this BIOS."
(
http://www.gigabyte.com/products/product-page.aspx?pid=4481#bios)
There are no other instructions...anywhere...on Gigabytes's website.  Nothing.  In fact, using their search engine at the top of the page, I can't even get a hit for "efiflash.exe" or "efiflash", which doesn't make sense because it's on the BIOS page for this board. 
The manual talks about Q-Flash and  the @BIOS utility, but nothing about efiflash.  I did find this page, 
http://www.gigabyte.com/webpage/20/HowToReflashBIOS.html which talks about those two options and a DOS option, but zero about efiflash.exe 
It would be nice if the instructions for using this utility were covered 
somewhere  on the site or in the manual.  I don't want to 'try' anything with a BIOS update utility if I don't understand what it is I'm supposed to do.
Also, any reason why this BIOS version can't be installed using two relatively modern utilities that Gigabyte has?  BTW, I used @BIOS to flash from F7 to F8.  I would have used Q-Bios but I'm not getting any BIOS screen video on a DVI-D connected monitor (one of the reasons I'm tyring to update...hoping for a resolution)  

Thanks!
