Windows 7: AHCI Not found in Bios

AHCI Not found in Bios

Good day,
I recently installed a Samsung 850 EVO SSD drive to my old Gateway GT 5676.
OS Windows 7 Home premium 64bit SP 1.
CPU AMD Phenom Quad Core 9600 2.3 GHz.
Motherboard 4006272R - Foxconn (Bengal) RS780 Motherboard.
Memory 8GB of DDR2.
Graphics Card(s) Integrated ATI Radeon HD 3200 video /Sapphire Radeon HD 3470.
Sound Card Integrated ALC888S HD codec 7.1.
Monitor 19" Samsung SyncMaster.
Hard Drives One Internal Samsung SSD 850 EVO.
One Internal 320 GB 7200 RPM SATA II hard drive.
PSU Ultra LSP 650W
Case Gateway 5-Bay uATX Computer Case.
Cooling CPU - Arctic Cooler Freezer 64.
Keyboard HP.
Mouse Logitech Laser.
Before Installing Windows 7 HP and wanting to take advantage of the drives "Trim" function, I checked the bios settings in "Integrated Peripherals"
I was hoping to change the on-board sata mode to AHCI.
I couldn't find the AHCI setting anywhere! This board is SATA II only, Would this board (foxconn (bengal) rs780 Rev 1.0) be to old to be able to select the AHCI mode?

The drive did come with software, which I did not install.

Thanks
N2

Hi,
I doubt it has it
I would imagine an old computer would have old legacy bios.

Why do you need it ahci ?

You'd probably read references to trim here,

I read somewhere that the "trim command" was a function that automatically cleaned up old and expired cluster data on SSD cells.
Would there be anything on Samsung's software that would be beneficial?
I didn't load it since this is a fresh install and I don't want a bunch of junk loaded I don't need!

Not really windows is more than capable of using trim instead defragment on a ssd,
I believe there is a command prompt string to enter to confirm trim is enabled but I can't remember it

My laptop doesn't have it either, as long as you get an OK in the top left of this tool, (This doesn't install, you just run it from the unzipped folder)

Download AS SSD Benchmark - MajorGeeks

You should be good.

This is from my desktop but you can see the green OK's in the upper left,

I don't like that bench test it seems to be full of it with sh in front

Very wild results from it on my older system

Might be good for the example Derek was referring to though but don't focus on the numbers too much
The real test is actual usage which should knock your socks off now

I only see Vista drivers for your computer but there is a SATA Raid driver, Raid drivers usually have the AHCI driver with it.

Which this one does have an AHCI driver,

I would give that driver a try myself, it should install fine. Most Vista drivers will.

I'm running win 7 Home Premium, will that matter? As well, after the install will I need to go to the bios to make changes?
