Re: TIP: how to enable DIPM for SSDs on Windows 7

MSAHCI.SYS is loaded under Device Manager/Think (computer name)/IDE ATA/ATAPI Controllers/Standard AHCI 1.0 Serial ATA Controller. The driver is up to date according to the OS!

I also have an ATA Channel 0 listing under controllers. This computer doesn't have an IDE disk drive option but I am guessing that it is probably for a drive connected via USB.

Puzzling . . . by the way, thanks for thinking about this.

Re: TIP: how to enable DIPM for SSDs on Windows 7

Start Device Manager, click "View"/"Devices by connection".

Expand and try to find your device in the tree, navigating thru the following nodes:

ACPI (...) PC
Microsoft ACPI-Compliant System
PCI bus
Standard AHCI (...) Serial ATA Controller
ATA Channel (...)
<YOUR SSD DRIVE>

Take a snapshot of the expanded tree and post it here.

Cya.

Arrow And it works like a charm!

Taken from my drive's S.M.A.R.T. attributes today:

Power-On Hours Count = 37

I've been using this mofo in my laptop for 30 days, more than 10 hours/day, and the drive was REALLY up only for 37 hours.

So it turns (most of) itself off until it's really required, without the OS having to tell it to stop working, thanks to DIPM being always enabled.

No wonder why my laptop's battery is taking longer to get depleted.

Question Re: TIP: how to enable DIPM for SSDs on Windows 7

I have Intel 320 300GB SSD on Inspiron 1520 with Windows 7

I followed all the process (Chanding the registry and changing the power option to "HIPM+DIPM" but Intel SSD Tool still shows me that, Laptop system detected, DIPM should always for enabled.

I have AHCI in SATA

Please help

That's normal.

Intel SSD Toolbox will never detect DIPM usage on a laptop.

The modifications won't change DIPM detection by SSD Toolbox (unless Intel updates the program). But they will enable DIPM.

You can make sure it's working by running SSD Toolbox, choosing "View Drive Information", scrolling down to word 79 and cheking bit 3 - "Device Initiating Interface Power Management (DIPM) Enabled" - if it's set to 1, it's enabled.

This awesome guide is very useful (thanks Whammamoosha) so it deserves a sticky!

Thank you Whammamoosha, but there is no way to get rid of that message in SSD Toolbox? if it is enabled than why is it displying that message?

Since laptops have TWO parallel energy profiles (on battery/on power) that can be active at any time, the manufacturer can't predict (better -- don't want to) which profile is being used. It's up to you.

I acknowledge that my first answer was RUDE, so I've edited that to look less BRUTAL.

BTW any other questions about not being able to make sure DIPM will be used at all times in a laptop is subjectable to what Michael Tritter's character (BRUTAL in "The Green Mile") went thru with House when he first appeared.

Just kidding

Exclamation Re: TIP: how to enable DIPM for SSDs on Windows 7

WARNING: the latest version of Intel SSD Toolbox (3.03) does the job, but not for custom power plans - only for the preconfigured ones (Balanced, High Performance and Power Saver).

If you have a custom power plan, you'll have either to delete it and re-create it using one of the preconfigured plans (after using SSD Toolbox's System Tuner), or use the steps in this guide.

Exclamation Re: TIP: how to enable DIPM for SSDs on Windows 7

Well, my big-time travel dweller is gone. An HP NX 9420, didn't live up to the hype, never delivering decent drivers, whether in terms of time or features/reliability. Ended up dying due to a project maldesign: the heat pipe would leave its X1600 overheated all the time.

It's been some time that I've sticked to Dell after that one. Not for me until now (since my former NB was still working), but for others. Even in a 3rd-world country, where I live, Dell is paramount in being respectful and price-wise. I've been choosing, like I always did, machines for one person or another, from time to time. And the last 8 systems that I advocated for were Dell's, with only one complaint. Not because they are superb in every way (nay!), but because it was the most sensible choice when taking into account price/performance (which for me is also paramount).

I've gotten a Vostro 3560 with everything on top (HM77 chipset). Why am I posting it here?

To get right to the guts of it, my boot time with my good old X25-M more than halved. Under the hood of my NX 9420 it would take a little more than 30 seconds, with this fella here it's less than 14 seconds. I don't know whether it's the chipset which is more efficient (maybe it's more event- and less time- driven), but the boot time difference is impudent. SATA improvement doesn't explain all that.

The question that I really want to raise is whether SSDs were being underutilized until the last crop of HW came out (HM77 in my case). And I sincerely believe so.

Re: TIP: how to enable DIPM for SSDs on Windows 7

Does anyone know why Windows 7, and Windows 8 64-bit doesn't show this power management option without modifying the registry? Is there a reason why it's hidden or simply a bug of the operating system? Seems like the EPA or some organization would have insisted on a patch by now to show it (the reg edit).


BTW I did not have to restart, it was available immediately after modifying the registry in win8.

When was DIPM implemented to SATA?

For Intel SSDs (my case), using this procedure is not necessary any longer. Latest Intel SSD Toolbox takes care of everything in the "System Tuner" section, although the energy settings in Windows Power Options are kept hidden.

Moreover, enabling the settings to be viewed/changed like in this how-to showed everyting set to HIPM, not DIPM. Clicking on Drive Details on Intel SSD Toolbox's home screen and verifying word 79 bit 3 it says DIPM is enabled, though.

Either Windows after some update left the HIPM/DIPM manageable only for HDDs, or Intel SSD Toolbox is overriding the setting by establishing a hook at a lower level, or a combination of the two.

As for your last question, I performed a search but couldn't find the answer for it.

Kind regards,

Whamma
