Intel 520-120g sometimes SATA1, sometimes SATA2 on ICH9R

Hey Guys,


Just purchased an Intel 520 120gig SSD


I have a Gigabyte EP35-DS3P motherboard (P35 + ICH9R)

I am running the SSD on port 1 of the ICH9R in AHCI mode with a fresh windows 7 Ultimate install with latest chipset and Rapid Storage drivers.


Intel Rapid Storage Technology app mostly shows the drive @ SATA 1.5Gb/s, whilst on occasional boots it shows as SATA 3Gb/s


I have tried port 0 and port 1 of the ICH9R

I have tried 2 different SATA cables (am currently using cable supplied with drive).


Needless to say i'm not getting the performance i'd hoped for.

I realise my board does not support SATA 3 (6Gb/s) but at least if i can get the interface to consistent run SATA 2 i'd be happy.


Anyone have any ideas?


Any help appreciated.
