How to enable AHCI on my Pavillion m7 1015dx, contradictory to information.

I have a Pavillion m7 1015dx with windows 7. I installed a Samsung 840 pro series 512 GB SSD as my first with a clean installation of Windows 8 and made my 1 TB HDD as my secondary drive. My BIOS, insyde H2O F22 and is very limited and I can't determine if my storage controller is set to AHCI. All the forums I've read say more recent laptops are on AHCI by default. However when I run the Wizard software that came with Samsung SSD is says "AHCI is not enabled" and my bencmarks of reading/writing are 519 / 480 MB/s respectively, when this disc is announced 540 / 520 MB/s. Also when I run PC Matic which recognizes them SSD also claims AHCI is not enabled. Who should I believe? If it is how can not turned on I activate the AHCI. If it is on why these two other programs would state that it has not been activated? Even if read/write speeds are not as advertised that it starts in about 10 sec, even with the judgment. My concern is the life of the drive and if the TRIM is set correctly.

Thank you. You have an idea why these two other programs of State AHCI is not enabled, I don't expect you to know the answer on this I was wondering. Thanks again.

These programs are looking for specific registry keys in the operating system to see if they are enabled.

HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci\\\
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV

That's why they tell you that it is not enabled.

The following image is from the office, I use that has a SSD as boot drive. The AHCI drivers are installed and activated.

  • Satellite A100-237 / PSAA9 - how to enable AHCI (SATA Native mode)?

    Hello

    I have the Satellite A100 - 237 (PSAA9) and I would like to activate the AHCI (SATA Native mode). But in the BIOS there is no settings as AHCI or SATA mode.

    Is it possible to enable it in any other way (hidden fixing, utility sw)? Or only new special BIOS for this update (I have the latest 5.90) can solve this problem?

    Thank you for the answers.

    No response for the last 5 days. Of course, there is no special hidden parameter or BIOS. ;)

    As far as I know that there is no hidden settings and also no special BIOS. If something like that exists perhaps for technicians and non-public use.

  • How to enable AHCI mode on computer laptop dv6-7280eb

    Hello

    I just replaced my old hard drive to a new evo 840 Samsung SSD.

    It's a laptop DV6-7280eb HP with windows 8.1 on it.

    Software Wizard Samsungs tells me that AHCI is disabled.

    If I look at Device Manager storage controllers it says Mobile Intel Express Chipset Sata RAID controller.

    PC Wizard 2014 tells me this:

    Disk controller: Intel 82801HM (ICH8M) 3 port SATA i/o Controller cc = RAID
    Mode: RAID
    AHCI: Yes
    Legacy IDE: Yes
    NCQ: Yes
    Port multiplier: No.
    eSATA: No.
    I/o ports: 1 available on 6
    AHCI Version: 1.30
    Bandwidth: 6 Gb/s

    So is my question, possible to put in AHCI and RAID mode not?

    THX in advance

    No, but you don't need to worry about this. RAID is fully compatible with a single SSD drive and provide the same benefits for the SSD as AHCI. It's really AHCI RAID where the AHCI = "yes".

  • Equium P200D how to enable SATA AHCI mode so I can install OSx86

    Hi im trying to install OSx86 on my new laptop Satellite P200D-139 I bought this week.
    I need SATA AHCI mode value. All other pc, I used, I was able to do it in the bios but with this laptop, the bios is so cut off from the option isn't there.
    Does anyone know how to enable AHCI mode so I can get OSx86 to start.

    Thank you
    Mark

    If I'm not mistaken, you get the famous message "still waiting for root device", right?
    Well, I really do not have much experience in the Mac OS, but it appears because of SATA drives and Yes, you're right, AHCI mode works for most of the laptops or desktop computers.

    I think there is no way to activate this option. But you may find help looking for some instructions on osx86project in google.

  • How to enable the AHCI for SSD on M6-1010TX laptop computer HP

    HELO

    Have tried to install an EVO of 840 Samsung 240 GB SSD on my laptop of M6-1010TX with WIN7x64 i5/4 GB and running.

    The SSD seems to work OK, but I when I run Samsung magician this is a warning that it must be set to AHCI.

    Also, most of the menu items are grayed out and unavailable in Wizard, so I can't see or adjust all parameters. I don't even know if the TRIM work.

    There is no possibility of setting to AHCI in the BIOS. (In fact there is no provision for seting pretty much anything in the BIOS)

    I've seen a remedy to a similar problem on this forum under 'How to enable AHCI for HP ENVY TouchSmart m6-k015dx Sleekbook' which offers to upgrade to the latest version of Intel RST, which is supposed to give favor SSD attitude to go with the 7 series Intel chipset.

    I already have the updated HP version of installed RST (2012-05-04 11.1.0.1006), but the Intel site has versions up to 13.1.0.1058 in date 27-05-2014.

    Anyone know if these later versions of Intel are safe to install?

    PS - I 840 Samsung SSD EVO running on 2 HP ProBooks's a little older, and they run like lightning.

    A simple setting in the BIOS to enable the AHCI is available on these. Why not in the new M6?

    Thank you

    OK Hüffer---> we have a update

    I had the opportunity to re - install the SSD drive this morning.

    It seems that you were mostly correct, but there is also a bit of a conflict between the Samsung software and HP hardware.

    When I re-installed this time I connected the SSD in USB BEFORE installing the software (Samsung instructions say to connect AFTER insalling software). This has resulted in much better recognition of the SSD and all the options are now available in Sasung magician.

    EXCEPT - 1. He always warns AHCI mode being "Deactivated (IDE or RAID).

    2. it does not recognize the SATA 3 Interface

    HOWEVER - it seems to work quite fantasmagorically FAAAAAAST

    Samsung Benchmark gives random read/write speeds about 30% above their maximum rate quotes

    These reference speeds are about double what I get from the above, 2 HP ProBooks who have SATA 2 interfaces, so it seems that the SATA3 interface actually works correctly.

    I am now very happy with this performance (but I wish that AHCI warnings were not there)

    So the secret seems to be to connect the SSD drive first and do believe not all alerts when the evidence says it actually works OK.

    Thank you once again to Hüffer,

  • How to enable the AHCI for HP ENVY TouchSmart m6-k015dx Sleekbook

    Hello

    I upgraded my hard drive to an SSD and it's done. Laptop works very well.  The Samsung SSD software installed and it says that I need to enable AHCI to get the SSD running at full capacity.

    I searched the BIOS and don't see anywhere to change that.  I then went to the Device Manager in Windows 8.1and I don't see any ATA/SATA controller.  All I see is a RAID controller. RAID controller in a laptop?

    Can someone tell me how to activate the AHCI?

    Thank you.

    Hello:

    Because your laptop is a portable consumer there is no way to change the BIOS to AHCI setting.

    The BIOS is set by default for RAID on your model series because some models come with one of these drives covering with a SSD and for a technical reason, that those who must be configured in RAID 0 mode so that Setup work right.

    It is my understanding that if you install the latest driver Intel RST, which is supposed to support TRIM SSD starting with the Intel 7 series chipset, and yours has series 8, so he must have full support for one SSD usage even in RAID mode.

  • How can I enable AHCI in dv7 6199us? And install windows on a SSD?

    Hello!

    I got help.

    How can I enable AHCI in dv7 6199us? And install windows on a SSD?

    Intel based computers, like yours, are usually set to "RAID", which is a superset of "AHCI". Basically, if the BIOS won't let you choose between "IDE mode", "AHCI" and "RAID", leaving in the RAID led to you everything done "AHCI". In this case there is no need to activate the AHCI, as RAID will support an SSD anyway.

  • Why I can not connect on the accounts of Firefox to put in place the synchronization? FF30 + keeps telling me how please enable cookies; cookies ARE enabled, already tried Safe Mode.

    Exactly what it says on the Tin.

    Why can't I connect to Firefox accounts to set up sync to my laptop? FF30 + keeps telling me how please enable cookies; cookies ARE enabled, and I already tried Safe Mode. This has happened since the new Sync has been set up, so I think that nearly 30 FF. I'm now up to 34 FF version and it still does not work. I was not able to sync from the "update".

    Problem #1: Going to about: accounts and clicking the Get Started button Blue opens a blank screen. It's not even a prompt on the cookies. It's just empty. Screen attached.
    It comes from before the modules are disabled. If they are disabled in Mode safe, we go to the #2 problem.

    #2 problem: I've skimmed a thread (https://github.com/mozilla/fxa-content-server/issues/1017) and I tried connecting to sync through accounts.mozilla.com instead, but if the screen does not turn white while the modules are always enabled, "Enable cookies" warning are as far as I can get. Go to about: accounts in Mode safe mode gives the same result. I deleted all my cookies and my cache, FF restarted several times with and without active modules and still nothing. I browsed this forum of support for similar issues, and while other people have the same problem, no other threads have been solved yet. Several later versions of FF, it is far too long for this question still unresolved... Screen attached.

    I know where the Firefox Cookie Manager, and I have enabled all settings. I was even able to third party cookies (even though I shouldn't really because they are unnecessary). No difference. Screen attached.

    I looked into: config and looked up the word 'cookie' in names, but even this is useless to me since I am not a programmer and so ignorant of what mean really all of these parameters. Screen attached.

    I'm at the end of my rope here, guys. It has been for months. A year. Maybe more than a year. I don't even remember. I just got a new camera and I don't want to add all my Firefox information one by one. It doesn't seem to be a way to contact Mozilla directly, so... Someone help please...

  • How to enable JavaScript on Firefox 32.0 to my Windows Vista desktop?

    Hello: I'm watching youtube videos were freezing after about 15 seconds. The good folks at Google lead me through troubleshooting tips. I definition standard (and slow) DSL and the other trick is to enable JavaScript. I'm not a computer expert. Pls advise me how to enable JavaScript.

    Thank you very much.

    In Firefox JavaScript should be enabled by default.

    If you want to check, and then type Subject: config in the address bar (address) as you type www.example.com

    Then in the filter box type top of page in javascript and you should find the javascript.enabled is the default value and true which means that it is enabled.

    Just to be sure, Java and JavaScript are two different things, and Java is not necessary for Youtube.
