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?
 
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.
