Hello.

Concrete example for

880g/sb850

Windows 7 x86 driver

AMD AHCI Compatible RAID Controller

Advanced Micro Devices, Inc.

date: 29.12.2011

version: 3.3.1540.29

is working together with

SCSI\Disk

Microsoft

date: 21.06.2006

version: 6.1.7600.16385

installed for

SCSI\DiskAMD_____x+0_Stripe/RAID01.10 (x+0 RAID array)

or

GenDisk (single disk)

is working together with

BIOS AMD extention

version: 3.2.x

1. Does not support HIPM power management.

2. Can not transfer data faster than 1-1.5Gbit/s per SATA physical port for tested SSD single disk (in comparison with ACHI mode, where the same port can transfer up to 2-3Gbit/s with the same disk)

In fact, SATA physical ports works in "legacy IDE mode with hotplug support". I do not know about data transfer rate, but why HIPM is not supported and unused HDD device can not power down?

The same with AMD sb710 and appropriated software.

Who are maintaining the "AMD AHCI Compatible RAID Controller drivers"? How to post feedback to them?

1. Installed devices

2. There are no power settings for ACHIand can not be enabled

3. There is no HIPM support by AMD RAIDxpert

Does anybody else use RAID?

but why HIPM is not supported and unused HDD device can not power down?

The problem is not only that there is no LPM support for "AMD AHCI Compatible RAID Controller", but computer is insomniac - can not sleep and its HDDs can not spin down, while power option "sleep state controlled by software" is enabled. The suspicious program, blocking sleep state is "AMD AHCI Compatible RAID Controller" driver. But i am not sure.

No, this is not the "AMD AHCI Compatible RAID Controller" driver.

There is way to checkout, run as administrator

>powercfg -energy -output .\report.html

or
>powercfg /requests

SYSTEM:

[DRIVER] kX 10k1 Audio (3550) - Generic

to override incorrect driver request, type

>powercfg /requestsoverride DRIVER "kX 10k1 Audio (3550) - Generic" SYSTEM

I suppose the last line could be installed as taskschd.msc (periodic) job if the changes are not permanent for reboot.

I have answered to myself.
