Need some help with an SSD issue:

I switched from IDE to AHCI mode in BIOS and my Windows 7 startup time went from ~20 seconds to over a minute. Can anyone help me figure out what's up with that?

System specs:

3.2Ghz AMD Phenom II X4 955
Asus M4A88T-M/USB3
2 x 2GB Kingston PC1333
Asus GTX460 1GB DDR5 256-bit
60GB OCZ SSD Agility 2
150GB WD VelociRaptor 10k RPM









SSD was originally set to IDE in the BIOS. I updated the firmware to the latest (1.37), edited the registry then switched from IDE to AHCI in the BIOS (kept blue-screening before I edited the registry). After that, it detected and installed the AHCI drivers, but startup time was a lot slower.

WEI only went from 6.9 to 7.1, and there was only a minor improvement when I ran the benchmarks (screenshots are under AHCI mode).

Any ideas/suggestions?

Thanks for the advice. I did as you suggested and installed the AMD AHCI driver. Boot time is back down to ~20 seconds, but when I check Device Manager, no AHCI controller appears there anymore:
