What is AHCI

What is AHCI and why might I choose to try to use it over choosing the defualt settings ("optimised defaults").
can someone explain in plain english about SATA / AHCI, and how the board handles a sata disk on the six main sata plugs. (I presume jmicron is doing something strange and different, but I'm only using it for my legacy IDE drive and my DVD where performance is not critical).

AHCI = Advanced Host Controller Interface
The AHCI specification describes the register-level interface for a Host Controller for Serial ATA 1.0a and Serial ATA II.
For example, MSI P965 Platinum supports AHCI controller with SATA RAID 0, RAID 1, RAID 5 and RAID 10 (ICH8R).
To enhance the IDE transfer speed, you need to install the JMicron IDE/SATA Driver.
cheers

Does nvidia chipset drivers have trim support?

I heard that using the Microsoft Drivers was better then using the Nforce Drivers from this post http://www.sevenforums.com/tutorials/61869-ahci-enable-windows-7-vista.html?ltr=A. My ADATA SSD drive Sata port died somehow and Plextor drive is the new one ima get soon so doing some research the MB only suport Sata II but the Plextor is Sata III and I think backwards compatable why I might not get full speed out of the drive I wana optimise it as best I can as the main Boot up drive as I have 2 matching 1 Terrybyte WesternDigital Sata drives for storage/other games installed on. So Leave Nforce drivers after I install them or use Microsoft's tryign not to install the Nforce's or do a update driver after and switchign back to Microsoft's I know both drives support Trim as via there decription and as of now on this backup Sata Drive trim command via dos promt shows trim is enabled in windows but does the motherboard/nforce drivers support it? (I will be back to check on this post for idea's sugestions and responces to any more info that is needed)

ahh okie what about AHCI for the single SSD drive not in any raid array or anything? as I was reading on another page > AHCI and SSDs
Typically, many hardware review sites, as well as SSD manufacturers are recommending that AHCI mode is used with SSD drives. However, we have run our own tests here in the forum, and we believe this is misleading, only where SSD drives are used independently (ie not in a RAID array). from the MSI HQ User-to-User FAQ Hm now that I think about it I think I ment AHCI Not Trim. Must edit the other post.

SatelliteA350D-BA3.Not sure if right forum.Hidden partition.Can I erase and re-merge?IDEandAHCI?

Hi. I am fairly new. Not sure if this is the right forum for this question. I plan to re-install the OS on my laptop and fix some hidden partitions on my hard-drive. I have soem questions and some questions about using the eSATA feature on the drive, or eSATA with the expantion cards.
AMD Athlon 64 X2 Dual Core 3800+ 2Ghz, 3Gb RAM, Vista Home Premium 64-bit Service Pack 2, ATI 3100. Toshiba Satellite A350D - BA3, AMD QL-62 processor
1. I have a Toshiba Satellite A350D - BA3. There was 1 hidden partition, and 1 that had the back-up and was erased with a previous install. Can I erase and re-merge the hidden partition? How can I see what is on the hidden partition? It is small. From the research I did, it is probably system files only. I made a dvd-rom back-up already, and have used it once. In XP this is how I looked at other ones, I have Vista on the laptop and it is pretty much the same. I looked in control panel - administrative tools - computer management - disk management. I can delete and merge partitions then re-partition: I would need to hook the HDD in the laptop to an external enclosure, then use these features in XP or another OS. Or is there another way?
- I want the whole HDD for the laptop formatted as one drive. But I don't want to render my laptop useless.
2. With this laptop does the BIOS need to be confugured as AHCI so the eSATA port and eSATA features can be accessed? On my desktop and this particular motherboard, that is the case. I have IDE on my desktop and it cannot access certain eSATA features without AHCI or RAID configuration. An Asus M3N78-VM if your curious. This is a new idea I have come across, and havn't even used the eSATA port on my laptop yet. I want to be able to use it. What about AHCI drivers? With the motherboard for my desktop I need a floppy drive to install them. Are they included with Vista? I have been told and read that Vista does/does not include these drivers. I assume that the eSATA port will work on the laptop automatically, and I don't need to worry about this.
3. Anyone know why this laptop does not show up when I search the Toshiba site? I cannot find this model number.
4. Anyone know how easy/safe the bios flash is for this model? I found the last one I believe they made for it, but I had a failed one and did not want to do that to my laptop since that is a waste of money. I don't like windows bios updates.
Any help is appriciated.
Thank you.

So this will completely overwrite any of the steps in this process?
sudo gdisk /dev/disk0
If you get any error messages at this point, report the error messages, don't proceed further.
You're now in gdisk interactive mode. Menus/commands are single characters followed by return/enter. So type ? and <enter> and you'll get the main menu listing commands. Type p <enter> and it will print (display) the current GPT. Since you have 5 GPT entries, you can't use a 1 for 1 GPT to MBR scheme like Apple does. The following suggestion is safe, but all hybrid MBRs are non-standard inventions, and therefore I can't tell you how Boot Camp Assistant or Disk Utility will react to this hybrid MBR should you decide to make changes later. What I can tell you is Windows, Linux, and Mac OS X themselves have no problem with this MBR scheme.
r <enter>        go to the recovery & transformation menu
h <enter>        create a new hybrid MBR
5 <enter>        add partion 5 to the MBR
<enter>          accept the default MBR hex code of 07
y <enter>        set the bootable flag
n <enter>        do not protect more partitions
o < enter>       print (display) the MBR
You should have two entries. One type EE, one 07, with the 07 entry marked with * under Boot. If you don't, report back. If you do, write out the update partition information, and hope a power failure doesn't occur for the next few seconds...
w <enter>     write partition table to disk
reboot. hold down option - you should be able to boot into either Mac HD, Recovery HD, or Windows.
I just tested this same five partition GPT and 2 partition MBR on a working system and the instructions above worked.
Note, so long as CSM-BIOS and thus MBR are required for Boot Camp instead of EFI booting Windows, we're stuck with flaky MBR problems, as well as the 2TB disk limitation for Windows boot disks.
If so, problem solved, thanks!

Slow Boot Up, Slow Login caused by AHCI so we used IDE Emulator. What is the ramification of that?

Hi,
We have Windows 7 SP1 Enterprise and x64 machines and we have slow boot up and slow login issue for a while. We thought it was clearly group policy causing it but it can be misleading because we have other machines that use the same
GPO but has no issue. On the other hand, the problem is prominent with a specific HP Model (Elitedesk 800G1 SFF) so when we focused on that model, we reinstalled/reformat the computer but to no avail, the machine would still be be slow as soon as it
joins the domain. The other option is to minize the services and startup items, but we can prove that other machines boot up fine with all the services and startup items running. So "Msconfig" helps but as much as possible, we don't want
to do this because we have several computers with slow issues. We also installed KB2775511 but we don't get consistent result.
What gave us consistent result was changing the BIOS setting from AHCI to IDE but I would like to know what are the ramification of not using AHCI. Our new machines were delivered with this BIOS setting so we suppose that this is the most appropriate
setting however, it screws up other things.
What are we missing, how different is the performance and is this change not recommended? Any thoughts?
Thanks!

Hi,
I just add another method to diagnose your problem. You can try to use xbootmgr to collect a boot trace of your system.
Refer to the link below for more details about the trace steps:

Re: Satellite L40 - What is faster - AHCI or compatible?

Which is better HDD in native IDE or AHCI with the Intel Matrix Console manager?

Hi!
Which notebook you have exactly?
However, I think with native IDE you mean the compatible mode?!
The AHCI mode is faster as the compatible mode but therefore you need the Intel Storage Manager.
I hope I could help you.

Mac Pro w Boot Camp - SATA, AHCI, EFI, BIOS - what can we do? (Cross Post)

I am trying to centralize the discussion of this particular issue which prevents the Mac Pro from being the ultimate cross platform system.
Please refer to the original thread located at:

I agree with all the posts. I did the whole thing again to 1.1 and find this system base device and the sata drive speed UDMA issue to be serious for cross platform. What I would like to know is what is the performance with the sata on the Mac OS side. I did a encode of video and it
didn't seem to be much faster than my G5 Dual 2.0 processor machine. I would like to hear from others on their video encoding to see if this sata issue goes throughout the whole machine. I'm dissappointed with the winxp thing. 1.1 is better and did alot better install, but I do realize that it is beta. Non the less, the sata issue is huge. What makes it worse is that Intel won't even give a little bit of support, basically they said to me that it was all Mac problems. I hope there are many changes, in the mean time the cross platform is not working for me. I did get autocad to run reasonable, but nothing like it should with the power under the hood.

Windows 8 64-bit install on 970a-g46 Mainboard AHCI and NVIDIA DRIVER issues

My Box:
MSI 970A-G46
BIOS 1.9 (AUG 2012) (Tried 1.11 but the nightmare started then)
AMD FX-6100 (STOCK SPEED AND SETTINGS) WITH OEM HSF
16GB PATRIOT VIPER 3 (1866) RUNNING @ (1600)
USED an EVGA 9800GT 1ST AND UPGRADED TO NVIDIA REFERENCE CARD GTX 550 Ti (1GB) WITH SAME ISSUES
90gb MonsterDigital Daytona SATA III SSD DRIVE (OS and minimal programs)
Antec HE 550
I am at a point of pulling my hair out. I decided to upgrade my system to enhance Diablo III game play. I got a combo deal on the mainboard and cpu, and thought the speed of the game caching on a SSD would also help. The first attempt which took a little struggle was Vista 64-bit. Eventually, I was able to get the OS to work with me, and it was smooth. Since M$ decided to offer the Windows 8 Pro upgrade for only $39.99, I thought, what do I had to lose. Well….lots of time. Now, I am not a newbie, though SSD drives haven’t been more than an interesting thought. So yes, I read many guides on everything from Trim enabled Win 7 and 8, and many other do’s and don’ts. What is driving me to the Netherlands of hell, is the installation and how buggy it has been. It boils down to drivers for the IDE/SATA/AHCI CONTROLLER. First, even thought it “sees” the SSD on installation drive selection, after pulling the USB installation drive, the system forgets it, and there is a “problem with the boot sector”. If you load the driver from the AMD site, it lets the install occur “fine”, but there is an issue with that driver which causes an irq conflict which leads to D3 audio issues and freeze ups. I did finally get things in order (not sure which driver I choose for that), and things were smooth, except I tried to install the GTX 550 ti and that led to a corrupt file error, which the system runs a check disk and cycles the “preparing to repair” and “diagnosing PC” a few times and never allows me to enter SAFE MODE (shift+f8), to disable the NVIDIA driver that is buggy, and doesn’t allow for the NVIDIA Control Panel to install without losing video, and starts the repair cycles again… Leading to ANOTHER RE-INSTALL...
My question, for the Windows 8 Pro installation on the 970a-G46 mainboard and then after install is complete, which driver is the correct choice for the AHCI/SATA Controller? All I find is Win7 64-bit AHCI inf’s, and SB7XX 64-bit inf’s (no SB950 INF). The Driver disk which came with the mainboard is very dated pre Win 8 stuff, ASMEDIA X106 which are not recognized by the OS as written for Win 8. AMD’s latest drivers are the ones causing the IRQ type lags and corruption.
What version, build and type of Windows 8 installations have you used on this mainboard, and what drivers allowed you install it without the above conflicts? Your input may decrease my insanity… So, thank you in advance…

Quote from: m0r9h3u5 on 28-January-13, 12:11:16
I understand what you are telling me, only the generic drivers deliver subpar results. What is the point of running those drivers instead of windows 8 certified drivers written for said devices. My last install is functioning better, but still windows update fails every attempt, the apps i install (ie. weather bug) on the start screen wont load... to me windows 8 is a big fail....but that is just my view...
OK...I also own the 970a G46, and my upgrade experience from Win7 x64 AHCI to Win8 x64 AHCI was flawless the first time. No problems at all. You are running an AMD chipset board with a nVidia gpu, which means that your chipset drivers are not automatically updated with every gpu driver update you do--this would happen automatically if you owned an AMD gpu because AMD includes them in its gpu driver install packages. But--all you have to do to get the proper drivers for your motherboard is go here and download them. You only need the *chipset drivers* from this page--you do not need the RAID drivers, of course. That's it. It's no big deal, and back in the days when nVidia was making motherboard chipsets you had to separately download both the motherboard chipset drivers from nVidia and the AMD gpu drivers from AMD if you did not also own a nVidia gpu.
From your description of your problems it sounds like your installation of Win8 is hosed and you need to format C:\ and clean install from scratch, anyway, so...
A note about AHCI--the *ideal* way to install the AHCI drivers is prior to installing your OS for the first time, you enter the UEFI and set "AHCI" in the appropriate place, instead of IDE, and *then* you reboot from DVD and install your OS which will automatically install the correct AHCI driver from Windows. After the driver installation is complete you should then install the updated 970a drivers from AMD as linked above.
However, it is actually very easy to activate and install AHCI *after* you have installed Windows in normal IDE mode:
To enable AHCI in existing Windows 8 IDE Installation's
Caution: Do NOT enable AHCI in UEFI prior to making the following changes in your Registry! If you had AHCI enabled alreadyin UEFI, disable it first and restart your computer!
Use WinKey + R and type Regedit in the command line and hit the Enter key, this will open the Registration Editor.
Go to:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/iaStorV
right click on Start, select Modify and set Data Value to 0
Close Registration Editor and restart computer.
While booting, open the UEFI Page and set the SATA Mode to AHCI from IDE
Save UEFI settings and restart.
Windows will now install the AHCI drivers automatically and they should work without issues.
In order to avoid installation problems just like you have been experiencing, here is what I would do in your shoes:
1) Set UEFI for normal IDE drive mode
2) Reboot into IDE mode and install your OS
3) After you have finished with the installation, you should be having no troubles in IDE mode. Then go to the instructions above on how to properly enable AHCI *after* you have installed Windows 8 in normal IDE mode.
4) After everything is coming up roses in AHCI mode and you are having no problems, then install the AMD chipset drivers as linked above and you are golden.
Those 4 steps worked perfectly for me the first time (the first time I got them right, that is...).
There's nothing wrong with Win8--this is strictly operator error caused by insufficient research into what AHCI is and how to properly enable it. The Internet has some bad info on Win8 registry settings for AHCI because of the developer preview and the consumer preview versions of Win8 that Microsoft released to the public prior to the final shipping build--many "instructions" for Win8 are therefore not valid for the shipping version of Win8. At first I made some of the same goofs that you did, but now you get to benefit from my hard-won experience... Good luck! Should work like a charm. And, registry AHCI is done differently in Win8 than it is done in Win7 or Vista. Also, the registry settings relative to AHCI in Windows 8 for AMD are different from the registry values that must be changed for an Intel controller.
Parenthetically, My FX-6300 (Vishera) will be here in a couple of days! Yeah!

K9N platinum - AHCI for Intel x25 SSD

Hello... I intend to set up an 80Gb Intel x25 SSD 2nd Gen (Win 7 - 64bit) on my system in a week or so its a K9N platinum v1, apparently I need AHCI set on the SATA channel - looking through the BIOS setup (Rev1.8) I can't seam to find this option - would someone be kind enough to advise.

I am quite certain that I do have the same motherboard. Here's a link to what I purchased:

I looked through my manual as well and didn't say any mention of AHCI anywhere. I guess it's not supported?

T520 - 42435gg / Sound stutter and slow Graphic performance with Intel Rapid Storage AHCI Driver

Hi everybody,
I have serious Problems with my 42435gg
Any time I install the Intel Storage AHCI Driver (I've tried plenty of different versions) which is suggested by System Update I experience a horrible Sound stutter and slow Graphic performance in Windows 7 64-Bit.
The funny thing in this case: If the external e-sata port is connected the problems do not occur. If the port is unused again, the stutter begins immediately.
The only thing I can do is using the Windows internal Storage Driver with which I am not able to use my DVD recorder for example.
The device was sent to lenovo for hardware testing with no result. It was sent back without any repairing.
Anybody experience on this?
Kind regards,
Daniel

What is the max. count of internal worker-threads in B1iSN 88?

Hi Experts,
We have an installation of B1iSN 88 with an ECC 6.0 and 54 SAP Business One installation. The Hardware is 8 Core multi-threads processor. 32GB Memory. Now we have a problem with the queuing of Events. What we have found is that the configuration of the internal worker-threads is set to -1(please see below for the settings). We change the settings to xcl.threads=20 and it improves the queuing. My question is what is the max. count of internal worker-threads per core? so that we can know how many worker will set and if we need to upgrade the CPU to 16 Core..
# The max. count of internal worker-threads afforded for the internal Scheduler (defaults to 1)
# The value of 0 means that there is no limit (what in general should not be set up).
# A negative value means the count of threads per available processor
xcl.threads=-1

Wilson

What a jump in performance when I swapped out the Pentium 4 620 mine had, for the PD 945, and tossed in 4 GB of memory.
That box will also run the Radeon HD 6570 with no problem too, which is what I put in mine.
The downside of that model is that there are no settings for ahci or raid.
I own or have owned every CMT since the d510 with the exception of the dc7900.
My main PC is now the 8200 Elite CMT which I installed W8.1 on.
It has an i7-2600 processor and 32 GB of memory, 1 TB SATA III hard drive.
I threw in a Radeon HD 6670 in that one.

What is the max size of HDD I can use in my dc7600 CMT

I am using an HP dc7600 CMT which is working fine after upgrading to a Samsung 128GB SSD, Intel Pentium D 3.4 GHz, 4GB RAM, and an AMD Radeon HD 6450. I am running Win 8.1 Pro x64, with the most recent upgrade, and have absolutely no problems. I now want to add a second internal HDD, and wonder what is the max size I can go to. Can I go to 2TB, or am I limited to a lower figure? 1TB? 500GB? 250GB?
Will be glad for some help here, especially if it has been actually tried in practice.
Thanks in advance.

P55-CD53, how to install SATA AHCI drivers and Matrix Storage Manager?

Please excuse my noobness as this is for my first PC build and much of it is Greek to me, but could someone please inform/educate me as to what the following drivers (link) are for and which need to be installed after a fresh installation of Windows 7 Pro x64? Do I need to install all of them because some of these appear to be redundant, just from different manufacturers, or am I mistaken? I have a single 500GB HDD but will probably add more down the road.

After booting from the Windows 7 disc, I selected Repair Windows, Load Drivers. Which specific controllers do I need to install for the P55-CD53 MB since there are multiple controllers listed for each of the four SATA compressed files?
Considering the multiple files and multiple controllers, is there no one out there with a P55-CD53 that has AHCI mode enabled that can give dumbed down instructions on how to do so?
The manual states "Select the appropriate RAID controller and press enter." Well... which one is the appropriate controller? Am I suppose to load the driver for all the AHCI controllers if that's even possible?
For the Intel P55 AHCI / RAID Drivers compressed file, these are the controllers available within F6flpy64\iaAHCI.inf:
Intel(R) ESB2 SATA AHCI Controller
Intel(R) ICH 10D/DO SATA AHCI Controller
Intel(R) ICH10R SATA AHCI Controller
Intel(R) ICH7M/MDH SATA AHCI Controller
Intel(R) ICH7R/DH SATA AHCI Controller
Intel(R) ICH8M-E/M SATA AHCI Controller
Intel(R) ICH8R/DH/DO SATA AHCI Controller
Intel(R) ICH9M-E/M SATA AHCI Controller
Intel(R) ICH9R/DO/DH SATA AHCI Controller
Intel(R) PCH SATA AHCI Controller
Intel(R) PCHM SATA AHCI Controller 4 Port
Intel(R) PCHM SATA AHCI Controller 6 Port
Also, regarding the dual BIOS controls for SATA/IDE/RAID settings previously mentioned, I believe SATA ports 1-6 are controlled via Intel and 7,8 are controlled via Jmicron. Considering my HDD is currently plugged into SATA 1, Jmicron probably isn't necessary for the moment.
Edit:
Turns out that none of the drivers for the controllers listed in iaAHCI.inf could be installed. However, I went ahead and installed the drivers listed for all the controllers in iaStor.inf. I reinstalled Windows 7 to get rid of the BSOD. I then installed the chipset drivers and Intel Matrix Storage Manager.

I got the hard drive upgrade kit and now have the old drive in the On-The-Go-Pro external enclosure and the new drive in the Macbook Pro. I booted from the old drive and now I'm ready to restore to the new drive using Disk Utility but I'm not sure exactly what to select as the Source and Destination.
Three disks are listed in the left frame. The new Samsung disk, the old drive in the OTGPro external enclosure with a volume called "Macintosh HD" and something called "disk 2" with a volume of Mac OS X Base System under it.
I think I should select "Macintosh HD" as the source and the Samsung Drive as the destination. But I'm not certain.
What's the correct source and destination?

So...... does anybody know what went wrong with Leopard !!!!!

I know a lot of install went well ,but not mine!!!!!!!
I have a MacBook that I can't install leopard on, my MacBook is only year old.
I love my Mac ....it's the best laptop I have ever owned. I don't really know what to do. The disk is ok (it clears disk check every time), how could it be my hard ware it's all APPLE. I don't see any real official recognition from apple about this problem and I don't see how they missed all bugs. I was really eager to install 10.5 ,but now I wish the guys @ apple would have just held back a few more months. Please someone help!!!!

I purchased my Macbook about the same time you did. Last November 1, 2006 when the first Core 2 Duo Macbooks came out.
I had no problems installing Leopard and I just used the "Upgrade" option.
Here are the details on my Hard Drive:
Intel ICH7-M AHCI:
Vendor: Intel
Product: ICH7-M AHCI
Speed: 1.5 Gigabit
Description: AHCI Version 1.10 Supported
TOSHIBA MK8034GSX:
Capacity: 74.53 GB
Model: TOSHIBA MK8034GSX
Revision: AH303B
My hard drive was already formatted in the "GUID" format. You might want to check this just for GP using Disk Utility...
You might also "Verify" your HD for problems using Disk Utility... also Repair Permissions....
If you have already tried the above, then you will probably need to take it into an Apple repair station.
Good Luck
