Currently socket 1155 motherboard with Intel B75 / H61 / H67 / H77 / P67 / Z68 / Z75 / Z77 chipset will support single side 4GB memory module.

Older socket 1156 and 775 mainboard will not be able to support it.

Due to on-board CPU limitation, A68I-350 Deluxe will not be able to support dual channel memory.

It will only support single channel memory.

Win7 64 bit will support SATA in AHCI mode.

So it will be best to change DVD ROM or DVD disk for finish the Windows installation process.

The maximum DDR3 speed for Intel G2020 CPU will be 1333 MHz.

So B75MU3B will support up to DDR3 1333 speed due to CPU specification limitation.

Please update SSD firmware v1.0 from Samsung website.

It will be able to fix the RAID problem.
