What are the odds the Bulldozer southbridge fixes I/O performance?

Just threw a Samsung F3 1TB in my SB710 motherboard and definitely feeling a bit miffed at my benchmarks versus the reviews of this drive on an Intel motherboard.

I'm hoping AMD makes a nice leap with their Bulldozer southbridge, but I give it 50/50 odds.

In bios under storage configuration, do you have the drive mode set to IDE or AHCI?

Same thing check your drive mode settings. AHCI makes a pretty nice difference on newer drives.

Windows 7 64-bit blue screens when I enable AHCI. Tried installing latest AMD southbridge drivers, no luck.

I'll update after I get a chance to try it out.

ACHI should be enabled in bios before Windows is installed. The Windows registry initials to either IDE mode or AHCI during the install. There is a workaround, however, after Windows is installed. Its actually a pretty easy fix. After the fix, then enable AHCI in bios.

Yeah, I did the AHCI fix and it's now within 1 to 10% of an Intel motherboard in Crystal Disk Mark. I guess I should change those odds they made up that last bit with the Bulldozer southbridge to 80/20.

Thanks for the tip, noticing a real improvement in game load times. This F3 is pretty spry, I can remember when people were talking about whether ATA100 was necessary over ATA66 with mechanicals. Can't wait for SSDs to start dropping below $1 a gig though.
