RST Driver Lockup / Freezes (Win7 x64 w/2 x 80GB X25-M G2)

Hello all,


I have reviewed some of the other posts in the forum, but haven't found any that directly address what I am experiencing with my configuration.


As always, it is a challenge to troubleshoot the source of the issue - driver? mobo BIOS? etc.


I just purchased two 80GB SSD X25-M G2 drives (SSDSA2MH080G2C1).  I connected them to my PC, I have an EVGA x58 Micro motherboard with updated BIOS.


In the BIOS, I have it set to "RAID" which the documentation indicates to me means that AHCI is enabled.


Installed a fresh copy of Windows 7 64-bit.


I installed the RST driver set in Windows and am able to see that the drives have NCQ enabled etc (that indicates AHCI is working, right? wrong?).


I have run CrystalDiskMark benchmarks and the performance was outstanding.


Through usage, be it web browsing (watching some Hulu) or playing games Modern Warfare 2, eventually the system freezes.  It is not a blue screen, but it becomes non-responsive (task manager won't open, etc).


I changed the Windows driver installed to the Intel MSM drivers 8.9 set, and this lock up/freezing does NOT happen.  However the benchmarks post statistically significant lower numbers performance-wise than with the RST drivers.


I installed the RST drivers from the Lenovo site 9.5.7.x listed in a post on this forum, and the freeze/lockups returned.


I am happy with the drive performance with the MSM drivers, it is damn quick, but it is bugging me that there is a 10-15% gain I could have with the RST drivers but there is no system stability.


Any insight would be appreciated.


Thanks in advance.
