BC,
I read threads like the link below which influenced my decision to set the controller to AHCI for a SSD BUT to be sure and set the BIOS and save BEFORE installing the OS.
http://www.tomshardware.com/forum/295783-32-ahci-goodLikewise, opposite as you, after I installed the OS in AHCI mode, if I now change BIOS to IDE mode, it fails to boot.
Yes, lack of DDR2 availability is my main issue now. I was even considering getting this GA EP45T-UD3LR:

Lisa maree,
My previous mboard failed due to debris falling onto the board while I had the tower laying flat working on something (don't remember what now). I watched the component (diode, transistor, resistor, or whatever it was) fry before I could kill power. lol
I didn't have my other desktop PC here to test the SSD's with. The BIOS did acknowledged them but the system failed to boot saying 'no OS found'. I wish I would have investigated further but Walmart is only 1/2 mile from my house for an easy exchange/return.
My PSU is Antec TRUE550 550W ATX, which is ~ 2yrs old if I remember right.
My CPU is 130w TDP, but the rest of the system is pretty light (see my specs - 2nd PC listed)

Thank you both for your replies. Look for an upcoming post about this machine not shutting down fully (Display goes dark but fans keep running - retains open windows etc. - will not restart via keyboard/mouse/power button/ will only shut down when power button is depressed for a few seconds - like sleep mode but will not wake?) if I can't get it figured out soon.
