Hi,
I have a dell mobile M4700 laptop with the following spec:
Intel Core i7-3840QM CPU @ 2.80GHz Family 6
Intel Core i7 @ 2.80GHz
Ivy Bridge 22nm Technology
Intel HD Graphics 4000 (Dell)
2048MB NVIDIA Quadro K2000M (Dell)
Motherboard
Manufacturer Dell Inc.
Model 035JKV (SOCKET 0)
Version 01
Chipset Vendor Intel
Chipset Model Ivy Bridge
Chipset Revision 09
Southbridge Vendor Intel
Southbridge Model QM77
Southbridge Revision 04

running win7 x64
Im trying to get the optical bay SATA 2 to function as AHCI .
i have a Crosiar SSD X neutron 240GB
i got a Caddy from this site http://www.newmodeus.com/shop/index.php?...index&cPath=2_3
I put the SSD in the Caddy and slide it in.
Bios recognizes the SSD as a "System Bay Device" with its serial number firmware ver and size.
OS works with the caddy SSD as it was a second HDD primary drive.
the problem is when i run a benchmark on the caddy SSD i get 100mb\read\write instead of 550.

ive tried to tweak the board using dell command configure but it didnt work
ive changed registry keys for PCIide and some others but still benchmark shows 100mb\read\write

is there anything im missing?
is it even possible to change the SATA 2 from IDE to AHCI?

Thank you

what do you by replacing the SSD AFAIK?

not possible. the SATA connector is for DVD thats why i had to buy the Caddy so i could connect the SSD to the CADDY and slide it in like a DVD

the original HDD drive yes, is connected to the laptop within its original bay.
the second SSD is actually connacted to the DVD SATA port.
i took out the DVD and saw that the SATA port connector on the board is different than the SSD connector so long story short, i googled here and there and found milions of happy users
who had the same issue and they resolved it as simple as plug and play.
so i tried to do the same.

i bought a DVD Caddy(for the use of addapter between the board SATA connector to the SSD connector) i attached the SSD to the Caddy, (btw, the caddy is the same exact shape as the original DVD was)slide it in
bios sees the new SSD as "System bay Device" . it sits on SATA 3 and function on an IDE mode. I have tried many modded drivers from your site tried 3 different DVD caddies :-) my system is running win 7 x64 with the latest chipset that i downloaded from this site
i read some tweakers about changing the pciIDE reg entry from 3 to 0 and some others reg entries with no success.
I think Dell made this machine with SATA 2 on port 3 to function only as IDE and there is no way to change it. could be?

Fernando asked you to swap the drives. Just put the HDD in the caddy and place the SSD where the HDD was before.

There are good reasons to do this:
- AFAIK you can not convert an IDE controller to AHCI by changing some Windows registry values.
AHCI needs BIOS/OROM support and the controller has different device IDs in IDE and AHCI mode.

- Use the HDD in IDE mode. An HDD will reach high speeds only during data burst (the beginning of the transfer).
For large files the AHCI features (like NCQ) are not relevant. NCQ is only needed if you work with a large amount
of files at the same time (i.e. importing pictures, compressing files, etc.).

- Use the SSD as the primary drive for your OS and programs. Everything loads faster.

- Use the HDD as a secondary drive for all your documents, pictures, etc. Or as a backup drive.
Or as a removable drive, swap the HDD with the DVD drive whenever you want.
A reboot is requered before swapping, though.

@ mr_nuub,
I did that it didnt change anything. just to get more clear, i want to use two SSDs --one in the HHD original bay and the second in thh optical bay.i would like to raid them Raid0.
anywho, i havent been using a 7400RPM disk in a long time as primary HDD. it was always an SSD.

@Fernando,
Hardware Ids:
PCI\VEN_8086&DEV_1E03&SUBSYS_053E1028&REV_04
PCI\VEN_8086&DEV_1E03&SUBSYS_053E1028
PCI\VEN_8086&DEV_1E03&CC_010601
PCI\VEN_8086&DEV_1E03&CC_0106

"That means, that your internal drive natively runs in AHCI mode. It is connected to an "Intel(R) 7 Series Chipset Family Mobile SATA AHCI Controller DEV_1E03"."( i tought that my second SSD the one in the optical bay is DEV_1E03, am i wrong?

If so, then why i am not getting AHCI performance from my second SSD on SATA port 3?

"This will not work at all, because your system obviously doesn't allow to set both Intel SATA ports to "RAID". "
there is an Intel update for MQ77 chipset im sure you heard about this SYSBIOS open source project. reading the data shit i can see that once the update is applied the SATA port 3 which is SATA ver2 would get more Voltage to perform as AHCI mode
furthermore i read that the update can add an option to the bios for the user to choose the SATA on port 3 mode. \IDE-AHCI-Raid
i may writing not so accurate information i just found out about this project today

Project name:
SYSBIOS coreboot
project pack:
CHIEF_RIVER_FSP_KIT

problem is, i have no idea how to implement it. i am familiar with GIT hubs but this project is beyond my knowledge

I did. I spent 3 months with Dell high level support. i got a board replacement. they claim that the SATA on port 3 which is SATA 2 should work as AHCI or IDE mode.

There is a simple test: download CrystalDiskInfo and check if your secondary SSD in the optical bay has NCQ activated.
Then it is in AHCI mode and other hardware (like a low quality connector/cable) is causing the problem.

BTW: If you don't see a standard IDE controller in your device manager, then it's running in AHCI mode, too.
