if you do what you do and manually set timings then there is no difference, however if one just sets a memory divider the board will auto increase the timings to help the booting of that divider. Since like 99% of people have no idea how to set the timings(JEDEC is an a-hole for not posting up the proper equations) mobo makers have auto rules which set timings.
SO if you just set 2800mhz divider with older BIOS and a new BIOS the newer one would give you much better performance at higher dividers like 2933.

Everything seems OK except one odd problem getting video, any video, to work. I was getting nada from the Xfired 7950's so I switched the HDMI to the mobo. I ended up draining the board and doing a cmos reset, switching bios back and forth, rebooting over and over and eventually the onboard video decided to work.
After that I set up the bios and booted into Windows, shut down, and reconnected my Xfired 7950's and they worked. I've seen this before on Z77 and never have figured out what causes it.....
After all the Windows install/disappearing drive weirdness I had with the first board, this time around I had a spanking new 840 Pro with the OS cloned and ready to rock. Three SSD's running on Intel ports with no problems this time......
good to hear the new one is working better!

I checked the memory compatibility list on GB site, but that RAM set is missing, the more similar set I see there is the 4x8GB (same speed). I guess it will be ok, not no harm asking (considering I already noticed many reports of problems with RAM on Z87 GB boards)
Yea should be fine if the 16gb kit is there.

What reports of problems of ram on z87 gb boards?
whatever he sees in this club or on other forums. lol The GBT Z87 boards just sell more so there will be more people with more issues, I mean for the first time ever GBT is outselling asus which would mean many more users unfamiliar with the UEFI and or using older DDR3 and having issues, but if there is an XMP issue it will be solved. There is an minor XMP issue which should be addressed soon enough as well, but doesn't have much to do with these lower speed kits.
