"i try with RAID MODE OR IDE MODE
Does not change anything
Why did you write IDE OR AHCI MODE ?"
OK what are you using the Gigabyte SATA controller ports 6 and 7 for? nothing correct. Changing its mode makes no difference so if your not using it so you might as well disable it to increase bios post speed.
bios
ONCHIP SATA CONTROLLER ( ENABLED ) correct
ONCHIP SATA TYPE ( raid ) correct
ONCHIP SATA port 4/5 type ( as sata type ) OK
ONCHIP SATA RAID 5 SUPPORT ( disabled ) correct
ONCHIP SATA 3.0 SUPPORT ( ENABLED ) OK , what happens to your RAID performance if you disable this function? Your drives are only SATA 2 anyway.
ONBOARD GSATA/IDE CTRL MODE ( RAID / IDE ) ? options should be enabled or disabled. Disable it as your not using it.
ONBOARD SATA/IDE CTRL MODE ( RAID / IDE ) ? options should be IDE or AHCI. Makes no difference if its disabled above.
Did you test with your drives on SATA ports 0 and 2 to rule out the possibility that ports 0 and 1 share bandwidth?
You say you have the FEB bios so your good there.
Is device manager clean? you never answered this question previously. No unknown devices etc? Can you post a screen shot?
You stated this in a previous post.
"When I installed WIN 7 64
He did not ask me to install BOOTDRV
AMD SATA RAID Driver (Preinstall driver, press F6 during Windows * setup to read from floppy)
http://www.gigabyte.com/products/product-page.aspx?pid=3420#dl Sata raid driver
Not installed
IN Device Manager
How do I install THAT"
Did you install the "AMD Chipset Driver (include chipset \ sata raid driver" from Gigabytes website?
If device manager is clean and you are using the latest drivers available the only other things I can think of are. What strip size are you using
on your RAID. Normally the default is 128k and on magnetic drives this works well. From the research I have done it may not be the best setting
for SSD's. The only way to know for sure is to try different sizes which is not so easy to do. Have you tried testing with Cool and Quiet and C1E disabled in the bios. And windows power management set to "High Performance"?
I hate to say it but if you have tried all of the above and device manager is clean I do not think there is much you can do short of getting an expensive add in card or changing over to an Intel platform.
BTW I have never liked RAID 0 as the risk for data loss is just to high. Even RAID 1 or 5 is more work than its worth. I'd rather Backup to an external drive or network drive. Its more manual work but you know what you have got.
