Windows 7: Poor SSD performance

Hi,



I'm using Team Xtreem S3 120 GB SSD with Windows 7. The intallation was performed on AHCI mode and drivers and BIOS settings seem to be ok. However I get a poor perfomance. With SATA2 connection, I believe I should get seq speeds around 200-250 MB/s. Here is what I get:

Crystal Disk Info

AS SSD

I think I have found the reason. My SSD seems to run as SATA 1 altough my other HDDs are on SATA 2 mode. Any idea how to fix It?

System Specs?

AMD 7750 Dual Core CPU
Asus M3N78-VM MB
4 GB RAM
Radeon HD 4890 GPU
1x SATA 3 SSD
4x SATA 2 HDD

SSD Supports SATA3 but should at least work on SATA2 speed since mobo supports it no?

Did you load drivers during the installation?

If you mean AHCI drivers, no I didnt. I went with default MSAhci drivers and later updated with nvidia drivers.

That's good. I experimented once with the Intel driver during an SSD installation, and my AS SSD benchmark score was quite lower than with the MSAchi driver. Your score looks extremely low.

Did you check your cable connections?

What should I look at the cables? I mean they are whether connected or not right? There is no half connection? I mean it either works or doesnt work at all? Is there an "in between" ?

AS SSD benchmark scores are right at SATA 1 limits. I need to find a way to change the drive connection mode to SATA 2. But how?

so you later upgrade to nvidia? was it okay with MS driver?
i know there is some problems with nvidia chip set drivers.

Things to try.
Remove nvidia one and intall default MS driver for sata controler.
Try to connect SSD to different SATA port on motherboard. (sata1 and then sata4 etc. try them all if you can)
Disconect all other SATA or IDE drives.
