Just thought i would post my experiences on this board. First up its the first board where ive ever experienced the slow boot after bios/before logon screen.
Have tried bios versions F4 to Current F10 Beta bios (currently F9 is giving the best results)
Ports 4/5 as SATA type
RAID 5 support enabled (allows more speed for each Sata port)
Disabled boot logo
Disabled all but primary boot device SSD array
No OC at all.
Through multiple fresh installs on an intel ssd 520 60GG raid 0 array, at first with default MS drivers - poor performance around 400mbps or less
This is on a standard 64kb stripe via amd raid configuration utility after bios.
Also tried the AMD drivers - latest from: http://support.amd.com/us/gpudownload/windows/Pages/raid_windows.aspx
Still not much improvement.
Using windows backup & acronis true home image plus back (boot CD with universal restore enabled
so it defaults back to MS drivers) i tried multiple restores to 64kb stripe, 128kb strip and 256kb stripe, all with fast initialization on (default).
Needless to say the best i could get was Read of 668.41 MB/s & Write 158.15MB/s - which is an OKish middle ground considering previous attempts.
However its still quite short of max performance of 550 MB/s Read & 500 MB/s Write per drive.
Finally, after talking to absic, he confirmed that were was no known work around for the boot time side of things - after bios but before windows actually loads. Raid setup does the standard 5 dots ( . . . . . ) while it detects, then it goes to custard. flashing cursor in top left corner ( - ) for about 10 seconds.
Then windows kicks in, takes about 20 seconds just to load that part. Overall boot time is about 60 seconds as the pre bios loading is quite slow too.
For anyone who is experiencing this, it does look like the chip sets responsible for all the issues, speed and slow boot times as on 880 chip set boards, or totally unrelated chip sets these issues vanish
Lesson learnt, AMD has failed on this chipset.
