6gb/s SSD laptop system stuck at 3gb/s

Hello,


Brand new Samsung 830 128GB sata 6gb/s hard drive is stuck in 3gb/s mode.


Laptop: HP DV7-4290US. Using Port 0 (unaffected by the port2-5 flaw).
Latest bios and drivers.

Intel Mobile Express Chipset SATA AHCI Controller 11.2.1006 5/30/2012.


hwinfo64 v.4.02 reports "SATA Port 0 6 Gb/s: Supported".

Intel Rapid Storage Technology utility reports SSD on Port 0 is currently at SATA transfer rate of 3 Gb/s.

Samsung SSD magician reports all OS optimization completed, and system is in AHCI mode.


Benchmarks consistently 260MB/s read and write.


Already tried LPM registry fix, uninstalling/reinstalling Intel RST.
The BIOS options are sparse and nothing to do with storage.

Any other ideas?

  1. Your laptop does not have 6Gb/s ports. Your drive is functioning normally.
  2. Why's HWInfo reporting 6 Gb/s supported then??
  3. http://www.intel.com/content/www/us/en/chipsets/value-chipsets/mobile-chipset-hm65.html
    Intel reports this HM65 chipset has support for 2 6Gbps ports. Is it the case that HP decided to disable both of them?? Or do I need to change a software or setting somewhere?
  4. The chipset supports it, but the laptop doesn't use it.

    Unless you're doing large file reads/writes to and from you wouldn't notice a difference anyways. Windows would load the same, apps would load the same ect.
  5. Your laptop is based upon the Mobile Intel HM65 Express chipset.
    That chipset supports 6Gb/s ports, which is probably why it's reported in HWInfo, but HP has not included 6Gb/s ports in your laptop.

    If your laptop supported 6Gb/s drives HP definitely would have indicated it in their product specs. It's a good marketing point to say that their product can handle the latest generation SSDs.

    Do a Google search, but as far as I know there are no Laptops, Notebooks, or Netbooks that have internal 6Gb/s ports.
