Force 3 Sata II problem Macbook Pro

[feddie207]

Hi

Just bought and installed a Force 3 120gb in my late 2008 unibody Macbook Pro. I have the latest firmware (1.3) and am running Lion 10.7.1. The problem is that the drive is runnning at Sata I speed when the system is capable of Sata II.

System profiler states:

NVidia MCP79 AHCI:

Vendor: NVidia
Product: MCP79 AHCI
Link Speed: 3 Gigabit
Negotiated Link Speed: 1.5 Gigabit
Description: AHCI Version 1.20 Supported

This limits performance to 130mb read/100mb write.

Is there any way to get it working at 3gb/s?

Thanks

Hi this seems to be the exact same problem on a sand force competitor's drive...

Hi

same here with the MCP79 AHCI on a Macbook Unibody Late 2008 (MacBook5.1)
competitors have solved the same issue with an Firmware Update for it :-/
Will there be an firmware update available in the near future?

Update: After a whole night without power i have cold started my macbook an now it shows me 3gbit... but how long? ....

Wow - I didn't even get that far. My Macbook (Late 2008) always communicates with the Force 3 F240GB3 at SATA I speed. Time for Corsair to adapt the fix provided by the "other manufacturers" firmware!?

There are a significant amount of macbook pro 5,1 EFI issues with SATA2 devices. 1.7/1.8 EFI corrected the negotiation, but freezes occur. 1.6 set the speed for devices to 1.5Gb/s but created other issues. It's kind of a mess. I have my momentus XT jumpered to 1.5Gb/s to get it to work consistently (no freezes, no boot issues, etc), and would like to get my Force3 to work consistently as well. The issue is that although running the 1.8 EFI I can get it to boot and install OSX correctly, but there are freezes (pauses of about 10-20 seconds) that occur from time to time. Those seem to be across the board with many SSD vendors. I have no issue with it negotiating 3Gb/s, but it's not stable enough for me. Would be nice if there was a software tool to force the drive to a specific sata mode...

I have the same problem with 2009 mbp, cant get it to work on sata II :( i just bought the Force 3 120 Gb ssd... and i have the latest updates on osx lion (efi is 1.7). i tried formating and installing snow leopard and still no luck (snow leopard comes with efi 1.7 pre installed also)... My force 3 drive has the lates 1.3.3 firmware. "Link Speed: 3Gigabit" so it should run on sata II but "Negotiated Link Speed: 1.5 Gigabit" only.
Bootcamp is running win xp and also only sata I speeds (around 100mbs).

I would like to hear something from admins (developers) if there is a possibility to get the ssd to run on sata II speeds what is supported by my macbook.

Sorry for my bad english its not my first language

I just bought a Corsair SSD Force 3, 120 GB on 9-dec-2011.
Firmware is 1.3.2

I replaced my internal HDD with the Corsair SSD in my MacBook Pro 13" (mid 2009) running on OS X 10.7.2 (Lion) latest firmware release (1.7) capable handling SATA II

I'am experiencing the same problems as lot of other Mac Users are reporting all around the Internet who are using Corsair SSDs:

1) Slow performance (101 MB/s write and 127 MB/s read using AJA Testing Tool)
2) Negotiated Link Speed: 1.5 GB

I still was not able to find a solution how to fix the existing issues.

Should I return the SSD? Is firmware 1.3.3 a solution for these issues (using Lion not Snow Leopard)?

1.3.3 did not fix it and i tried lion, snow leopard and bootcamp- no luck :(

Edit:

i found a thread :

i will try to downgrade from 1.7 to 1.6. some say it fixes the speed and stability problems.

[aer0x]

is there no fix for that out there?

Shutdown the Macbook Pro, Then turn it back on from by pressing the power button.

It should negotiate at 3GB/S

[ckunkle]

Just got the same drive today running firmware version 1.3.3, and it negotiates at 1.5. WTF?

Still no update?

Same thing!! Hangs are killing me! Sometimes the sound keeps playing (from iTunes or internet) and the screen freezes other times everything locks up and the rainbow spinner just keeps on spinnin. Pretty annoying.

I have a Macbook Pro 5,1 and updated firmware on everything (ForceGT 1.3.3, AHCI 1.20 <Product: MCP79>, EFI 1.8, TRIM enabled, Systems Prefs set NOT to go to sleep ever and I get freezes/hangs every once (about 4-5 per hour and sometimes more which mean I shut down and then start back up) as well as only SATA1 1.5 Link Speed. The old Segate HD drive I replaced ran at SATA2 3.0...

Zapped PRAM, took battery out of laptop and held down the power key to drain all electricity, used Bootcamp (which resulted in a lot of freezes and a subsequent clean install) and now just using Lion 10.7.3.

When it does work, the Force GT is faster at SATA1 than my old Seagate HD connecting at SATA2... but the hangs and freezes are debilitating during everyday use, especially anything at work and my computer suddenly freezes and hangs for 30 seconds at what appears to be random intervals.

CORSAIR, WHEN WILL YOU TAKE ACTION IN THIS RESPECT???

There is an infinite list of frustrated customers asking for it here, it is just ridiculous that no position is taken from your side.

Still waiting for a decent firmware update.....
