Crucial M4 not at speed on sata 3

I have a MSI P67-G80 mother board and a Crucial M4 256gb SSD. I get only about 260mbps read and 220 write. My read is to low and seems to be at sata 2 speed. Is there anything I need to do with settings? I am using the supplied sata 3 cable sent with my MB and I am plugged in on the sata 3. Whats going on?

  1. What SATA mode were you in when you installed your o/s on your SSD? You need to be in AHCI mode for best performance.

    Also, double-check that your SSD is plugged into port SATA1 or SATA2.
  2. I was not in AHCI when installing Windows. Yes I am plugged in the SATA 3 port. I guess I will have to do a clean install. Will this work for sure?
  3. No need to do a clean install. See Post #2 of this link to edit Windows Registry settings. http://www.ocztechnologyforum.com/forum/showthread.php?67697-Guide-to-enable-IDE-AHCI-without-reinstalling

    After you perform the edit reboot into BIOS and change the SATA mode to AHCI.
    When you boot back into Windows download and install the latest Intel RST drivers.
  4. It now reads to 428mps but wont pass the Windows experience index test because I cant get the driver to update. Can you point me to the right RST drivers because when I try to load the one I found, it keeps saying I have the latest driver which is five years old.

  6. Thanks, what happened was when I was pointing to the wrong folder. The driver is now installed but it doesnt complete the Window Experience Index though.
  7. Did you reboot after installing the drivers?
  8. Several times, I did turn on hot plugging in Bios what ever that is. It still doesnt complete the Index.

    Sorry, can't help you there. Might wanna start another thread in the Windows section of the Forum.

    If you can't get an answer a clean install might be your only solution.
