Samsung 840 SSD Only Sata II?

Just finished setting up my new 1762 w/ 680M and am perplexed on a HDD issue. I installed the Samsung SSD in the primary bay (closest to screen, label facing up) or so I thought, however it appears to only be running at 3 Gb/s. Did I somehow get the bays mixed up or what could potentially be the problem?

Thanks

 

You can try move the SSD to another bay to see if it still says SATA II.

 

If you open Device Manager>Disk Drives and 2X click on the SSD name it will list the drive's location on the SATA bus.

Location 1 should be the SATA III 6GB/s primary drive bay for your model.

 

It is undoubtedly a SATA III drive. Chances are that is not in the primary slot. WhatsThePoint's post is the easiest way to determine whether the drive is connected to the appropriate bay or not.

 

With regard to the SSD performance make sure write caching is enabled

Power management should be on high performance setting if you want to see good scores in benchmarking programs like Anvil Storage Utilities,CrystalDiskMark and AS SSD.

 

Actually, a large number of people who have this notebook specifically and try to put Samsung 840 drives into them find that they tend to only operate at SATA II speeds. I've seen posts here, on MSI's forums, as well as others all with the same complaint. No one has really been able to get one fully operational at SATA III speeds all the time. Some people manage to get it there for a while, but find that it drops down to SATA II speeds at times as well. Not entirely sure why, but most think it's a problem with the Intel driver.

 

Don't install the Intel RST.

Use the MSAHCI storage controller driver built into Windows if your bios is set to AHCI.

The 840 SSDs also have issues in Desktops with X79 motherboards.
