LINK to available BIOS versions from Gigabyte
- F1 First release
- F2a Updated CPU ID for Phenom 9950 125W
-Also slight naming changes in BIOS (Memory Controller Freq. -> Northbridge Frequency)
- F2
-HT Link can only be be decreased from bios, not increased. AOD can be used to increase it.
- F3h Updated CPU ID for Athlon X2 7750
-HT Link speed setting now works also updwards, earlier versions could only drop HT Link.
-C1E support option disappeared
-DCTs Mode disappeared (no option for ganged/unganged, defaults as unganged with 2x sticks)
-New type of BIOS settings saving option with baby blue background, supports saving to / loading from HDD, FDD, USB
-Maximum CPU multiplier raised to x35
-Maximum NB multiplier raised to x20
- F3i
-Nothing special changes (I did only a fast test)
^ All these have cold boot issue with ACC enabled.
-----------
- F3m Mentioned here
-Unreleased version that should have better compatibility with Phenom II's
- F3o "Update CPU ID (for AMD NPRP)"
-C1E support option back
-No cold boot issue with ACC enabled (I tried only once)
-SLOW posting when ACC enabled
-MUCH harder to get any overclocking stable
-This is the worst version (for Phenom I), but still it has some promising fixes. Not recommended for any overclocking.
- F3 "Update CPU ID (AGESA 3.3.20)"
-C1E support option disappeared again
-Cold boot issue with ACC enabled still there* but now it can be passed with simply pressing reset. After that POSTing is a flash compared to earlier versions.
(01/13/2009).
-Officially supports Deneb
*EDIT: I have had problems with booting and now it seems that after shutting down from XP, and powering up after, the reset button will do the workaround but when shutting down from Win7, I have to cut the power before getting it up again.
- F4a
-"Improve Phenom II CPU compatibility"
-"Improve Audio compatibility"
-No cold boot issue when ACC enabled
-Ganged/Unganged option back
-PCIe speed setting in AOD is acting weird. I suggest you to manually set PCIe speed from BIOS.
-Doesn't affect OC'ing, in fact, it can get you a better results.
-Highly recommended for benching
- F4
-"Update CPU ID (Support AGESA3.3.2.3 code / AM3 CPU)"
- F4V
-"Update CPU ID (for AMD NPRP)"
Might just add support for new CPU's.
- F5
-"Update ACC code and CPU ID (Support AGESA 3.3.2.4 code for Phenom X3 CPU)"
-Added EC Firmware (Normal / Hybrid) to ACC menu for core unlocking (Hybrid mode)
-Now resuming from S3 works ok
-Newest release
I am using this now, and will not look into older releases.
The best version yet.
If you need some of these, I could send them via email or msn. The versions that I don't have, are F2a and F3m
My experiences show that ACC doesn't work right in F3 bioses, so IF you need ACC to overclock your Phenom I, I suggest using F2, F4 or F5 BIOS
Updated 06-22-2009
I haven't noted ALL changes of the different versions (haven't tried F3m, F3t and F4V , so feel free to make comments and additions.
*Note that these changes and functionalities have been tested with Phenom X4 9950 BE. Experience can be different with other CPU's*
(Offtopic: AOD 2.1.5 will most assumably NOT work with this board, so get version 2.1.4 instead. I have tried both 2.1.5 versions (0218 and 238) and they will not even recognize AMD CPU. The newest 2.1.6 seems to work ok)
Update about AOD version 3 and newer: At least my rig locks immediately when AMD Boost is activated. Does not happen with older AOD versions.
