You're welcome :)

Someone with a X99 platform install the driver by the device manager (.inf) and everything works well ?

Which AHCI driver is most suitable for use in Win 10 x64?
Is it, or is it not recommended to use the Win8 driver?
Can't really seem to find it!

Thanks Fernando!
Well i gave it a try,and found that the performance gain is zilch... just under 1%
Which could as well have been a fluctuation between benchmarks!

Hello,
I just installed win7 pro SP1 on a samsung 950 pro 512GB. To get the installer to see the drive I used the version 1.4.7.16 under the install driver option. I have all drivers installed but no windows updates done but an getting some low speed results. The max I seem to get is 800/750MBps Read/Write. In the samsung software it shows IOPS are lower than max too. Once in windows I used the Samsung 950pro driver exe as well but results did not change. Where should I start? I am a bit puzzled. Specs below.

Asus x99-m ws on bios 501 (newest)
5820k (no overclock yet)
Hyperx 32GB 2400Mhz
NZXT x61 liquid cooler
TitanX gpu
950pro 512GB
Seasonix x850 850watt gold psu
Windows 7pro SP1 (no updates run yet)
All newest drivers

edit:
Was just informed that the m.2 is on pci-e 2.0 lanes on the x99-m ws board, likely thats all the problem is then but might try a win10 install to be sure there is no other bottlenecks. Now to find an affordable adapter for pci-e 3.0 x16

Hello,

OS: Windows 8.1 64bit
I've installed a 4TB WD Red. The drive was GPT initialised as I will use this drive only for data.
However, instead of expected available 4000GB, Windows shows only 3000GB. (not exact numbers, i'm just keeping text simple)
I was guided here and told that my Windows drivers should be updated in order to "fix" the missing ~1TB.
I see references in the OP to DEV_4391, my Windows Device Manager reports ...

but the following HWiNFO report says DEV_4390 so I am confused.
1) Is this AHCI package suitable for 4390/439C, or is there a more suitable alternative for my case ?
2) Is there a way to force Windows to "Re-initialise" or rescan the drive to its full potential after I change the drivers

Thank you.

The hardware reports from HWinfo64 ....

The DeviceID DEV_4390 resp. DEV_439C indicate, that your AMD SATA Controller is currently running in IDE (and not in AHCI) mode.
If you want to get any AMD AHCI/RAID driver installed, you have to set the AMD SATA Controller to "AHCI" or "RAID" within the BIOS before.

You can scan all drives from withi the Windows Explorer by doing a right clck onto them and choosing the options "Properties" > "Tools" > "Check", but if you want to check the performance of the drive, you will have to use a benchmark tool.

Firstly, thank you for the forum welcome Dieter.

Without installing anything, I simply rebooted, then enabled AHCI in BIOS, however, during the boot phase, Windows prompted that there was an error and wanted to enter recovery mode. I suspect this is because there is no suitable driver available for AHCI at this point - so i reverted to IDE and everything returned to normal.

So I guess I am stuck in limbo, unless it is confirmed that I can first install the drivers from inside Windows, reboot, change the BIOS setting, and THEN bootup successfully - in that order.

Finally, a happy new year to you and yours too.

Just wanted to report that on win7 pro and the 1.4.7.16 installer set has been working just fine on the asus x99-m ws with 5820k. No usb issues. I have it on the latest 501 bios. Im still waiting for the pci-e 3.0 m.2 adapter but otherwise no bugs I can see. I have since benchmarked the entire system at stock and at 4.5ghz and compares to all my other 5820k builds.

Thanks a ton for posting those drivers! I think its silly that samsung expects us to install 7 on another drive and use their cloning tool.

Thanks again , My uncle pc with AMD FX 8320 which was overclocked to 6.0 ghz was flying .
It was powered by Gigabyyte GA-970A-DS3P Which was running superfast with latest ahci drv and ultra slim xp(230mb xp sp3 with nlite)

Hi Fernando!

I have a HP 15-f018ca notebook, which has a bay trail-m celeron n2840 cpu. I have no luck installing windows xp sp3, even after integrating your rst driver (I can find 8086_0F23 / Bay Trail SATA driver from your inf file). I even slipstreamed all the device drivers. I used textmode driver under your instruction.

The full device instant path is: PCI\VEN_8086&DEV_0F23&SUBSYS_21DE103C&REV_0E\3&11583659&0&98

other info is:

There is no way turning AHCI off and I don't think it should be an issue. I tried the installation on 3 different laptops: A6-3400M (2011), celeron 1007u (ivy bridge, 2012) and i5-4200u (haswell, 2013) with ahci on. but stuck on this one (HP, celeron n2840). The laptop is quite slow on windows 7/8.1/10 and I've learned my cpu is only as fast as some ulv core 2 cpu, that's why I want windows xp.

The driver I integrated from is from : [Guide] Integration of Intels AHCI/RAID drivers into a Windows XP/W2k3/W2k CD, I choose option C. THe iso is a clean msdn windows Xp sp3 iso

When I don't press F5 or F7: acpi.sys 0x7E bsod
When I press F5 and do any ACPI related options: same
Press F7: 0x7B
Press F5 and choose standard pc and standard pc i486: 0x7B

Haven't tell MPS option as it took a long time and stuck on "Starting Windows" during the textmode setup

THanks for your help!
