[OFFER] Modded Gigabyte GA-Z77X-UD5H BIOS F16L

original bios was sent by user morvay, here.


this bios version f16l, has new nvme option on peripherals page, and its sub page which shows nvme drives detail table.
it may have some other updates.





i have few questions about modding bios:
1. original bios me was 8.1.30.1350 for Z77. i had flashed bios in that state on my motherboard, then by using
fwUpdateLcl64.exe -f 8.1.70.1590.rom
updated me firmware to 8.1.70.1590.

then i saved bios.rom from my motherboard and sent it here.
the question is: Is this the right way of doing it. Should i update me firmware on bios image, or is it safe to do what i did, to update on local live bios, then save it from flash chip and send it here.
Is it safe for somebody else to flash bios.rom saved from my motherboard, in fear or maybe erasing users unique data like lan mac and overwriting it with my own.





2. intel rst z77 module:
i was choosing from: 13.1, 13.2.0.2134/13.2.2.2224, and 13.5.0.2164. i had chosen 13.2.0.2134/13.2.2.2224. In previous bios mod i used 13.5.0.2164 and it was ok. wandering which one od these would be the best.





3. lan intel 82579V:
intel pro1000 undi 6.6.04
intel boot agent ge 1.5.62
efi lx killer undi 1.1.0.13

these are the modules from the last ubu version which has only one option for 82579V.
newer ubu versions have two options:

for i210/i211/i350 chips
EFI Intel PRO1000 UNDI - 9.5.05
OROM Intel Boot Agent GE - 1.5.89

for i82579/i217/i218/i219 chips
EFI Intel Gigabit UNDI - 0.1.00
OROM Intel Boot Agent CL - 0.1.16

i didn’t know which one is right so i haven’t updated to them.





4. cpu microcode
for ivy bridge in bios is the latest 306a9[21].

however, it had been mentioned earlier that version from 2013?. 306a9[19] is better for overclocking.
are there some benchmarks and comparisons between microcodes.
is 306a9[19] really that better.

Local FW update is enough, no need to re-work the bios image.
REST 13.1.1058 is overall the best, the rest is user choice if he wants to compare performances.
The EFI Lan, in the 1rst options is newer modules series 01.XX, also a user choice one new series or old series 6.6 to 9.5.
mCODE is correct, as far as i know don’t remember seeing here on this forum any values of benchmarks but really never looked for it, try a google search.
