It is currently installed on a rather old MoBo: Asus P5KC, in one of it's 4 main SATA 3Gb/s ports, along with 2 other HDDs.
The problem is, in bios, my mobo doesn't allow any other options than:
Sata configuration [Enhanced]
Configure Sata as [IDE]
for those 4 Sata ports.
However, if I connect the SSD to the so called eSata port, which is somewhere else on the mobo, I can then in bios go to "onboard devices" and configure that eSata to IDE or AHCI.
I don't know much about what eSata means, and I've even heard that AHCI can somehow be bad for SSDs. But since most say SSD ports should be set to AHCI mode, I figured I should ask, if it's a good idea to move this primary SSD to the eSata port.
Page 4-14 of your motherboard manual indicates that you should see an option for AHCI as well as IDE when you set your SATA Configuration to Enhanced.
Disconnect all drives from your motherboard and clear your CMOS (page 2-26).
Connect your SSD to port SATA1.
Set your SATA Configuration to Enhanced.
See if you now have an option to enable AHCI mode.
If so, set AHCI mode, save your BIOS settings, shut down pc and then connect your remaining drives to ports SATA3 & SATA4.
But for your set up, set the SATA ports to Enhanced, then ACHI! And install the SSD to them.
Stay away from eSATA, you won't get the speeds of the internal ports, even in ACHI. Plus, "eSATA" stands for "external SATA", which the plug for is one the back of the motherboard I/O panel, and you'd need a power source, too. It'd get way to complicated.
And I was gonna say you dropped a bundle on an SSD that may not work in your system, but I see that Cruical 256Gb are less than $300.00. I would have said you shoulda upgraded your mobo & CPU, but that would be around $400.00. Plus RAM for $50.00. Nevermind.
Apparently the P5KC rom doesn't actually have the AHCI option enabled in bios, despite of what the manual states. (it seems that it used to, in older versions, but not in v1203, which is the latest) Funny how it gives you the option to choose between [IDE] and nothing else.
I've cleared the CMOS, removed all sata drives, and I can confirm that there's no other option than IDE.
So here's what I'm gonna do:
- enable the AHCI driver in windows because otherwise windows might not boot http://support.microsoft.com/kb/922976
- flash the bios with the rom provided on those forums.
Foscooter, you're right about the prices, and the thing is, even if I had upgraded my mobo & cpu & ram, I would have still needed an SSD. The HDD is bar none the hugest bottleneck in most systems. I have to say, things are 10x less frustrating since I bought it.
Done and done.
Flashed bios using Asus ez flash 2 and an usb with the .rom file.
Checked to see if AHCI option now shows in BIOS. It does.
Booted into Windows to enable AHCI using that .msi wizard.
Shut down, clear CMOS.
Enabled AHCI in bios and re entered my settings.
Booted to windows, windows recognized all my (as of now) AHCI sata devices and installed them.
Restarted due to being prompted by windows.
Hello. I know its an old topic,but i have the same problem.
I have this mobo,and recently a bought a SSD,Kingston HyperX 120 gb,and conected to that internal eSata (near grafic card slot).I enable the AHCI mode,and it seems everything is OK.TRIMM enable,AHCI enable,sistem stable,except... read/write speeds.I only get about 135 mb/s. I stay with the 0809(i think is this number) BOIS.
I already had found other topics were is metioned this tweaked BIOS,but i have a little afraid to put it and something goes wrong. Anyone have some feedback about this issue?
