How to fix your SSD freezing issue (we hope!)

dbw09 · #1 07-13-2011, 06:51 AM

I posted this in another thread, but I thought it may be easier for the community to find it if I re-post this in a separate thread. Many new SSDs are experiencing freezing problems, and this is not only a Corsair and/or Sandforce issue as many other manufacturers are having this issue as well. Many people have had the freezing issues stop by using a simple registry edit that disables some power saving features for the SATA ports of your system. This has been proven across multiple platforms and systems to decrease/eliminate the freezing issues.

While disabling the LPM on every SATA port will work, it is easier (and also better for battery life/electricity costs!) to disable LPM for only the port that your SSD is on, typically Port0. To do this, follow the instructions below.

NOTE: Please follow these instructions at your own risk! I personally have used this procedure on 5 systems so far, and many others have used it successfully as stated on multiple forums. However, as with any registry editing, serious issues can arise if you somehow mess things up! Be careful!

NOTE: This only works if you are using the Intel RST drivers. If you are using the default MS AHCI drivers, this will not work.

1) Copy the below text and paste it into a notepad file, and save the document with a .reg extension.

2) Execute the file

3) This will disable the LPM for ONLY Port0, which will allow the SSD to operate without freezes (we hope!) as well as allow your other hard drives to still use LPM. If your SSD is NOT on Port0, edit the file to have it disable LPM on whichever port your SSD is connected to.

Definitely worth a try doing this LPM registry fix. I know Yellowbeard said it's not consistent, but that was on June 2nd. If we were to wait on Sandforce to solve the problem, we'd be on our 42nd day of waiting with no response/update to what the problem actually is.

The first link is for all ports (and thus all non-SSDs will have LPM disabled and is not ideal), so this is not the same. Also, the link from YB is quite old, and numerous online forums have stated the LPM edit does indeed work; I can attest to it on both SF and marvell controllers. Again, YMMV, but this is better than most manufacturers remaining silent on the issue.

The regfix seems to have fixed freezing and lockup with my 120 GB Force GT. So far 24h without any problems. Thanks OP.

Thank you for the post and help dbw09!

Just wanted to say that after enabling hot-swap and applying the reg-fix I haven't had a freeze in 4 days. Previously I got atleast 2 or 3 a day.

Seems like this has enabled me to use my drive without banging my head on the wall (repeatedly) :)

Thanks dbw09!

I applied the hotfix and have not had any freezes so far in 3 days.

I applied the hotfix and have not had any freezes so far in 2 days.

Thanks.

(I have assembled the pc with mobo asus p8h67 m evo + cpu intel i5 2500k + 4 gb ram ******** + ssd on port(0) sataIII corsair force3 120 gb replaced with rma with serial number 1124 on the box).

What is the LPM? Is there any reason not to do this? Is it reversible?

RAM GUY · #11 07-20-2011, 12:16 PM

I would suggest saving what is currently in there on a note pad, and then make the change in case you want to change it back.

I think I've been experiencing this issue since I owned the drive so I'm going to give this solution a try.

Scenario.
- Cold boot, system "may" freeze after a few minutes use. Only solution is to do a forced reset from power switch.
- On 2nd or 3rd boot, system will behave flawlessly

Before finding this thread, I fresh installed W7-64-SP1 onto the SSD - and have just had the freeze.

Running the same OS on the RAID-10 on the same system has never shown the issue.

I'll post any results I find.

Please do. I'm still seeing quite a few people post here and at other locations that this fix does not fully resolve their issue. But, we certainly hope it does.

Is there a fix for similar problems when using the onboard Marvell SATA-3 ports?

biatche · #15 07-21-2011, 06:35 AM

Seems to have reduced the frequency of the problem, but it still happens. P55 board. This is on a Force 3 60GB and intel rst 10.x. Are there any Force 3 users here without ANY issues at all? Will we need to wait few months for a fix? just like when first force series was initially out...
