I seem to be reading that RST driver 11.2 has the support - however Intel says only for it's motherboards.

Purpose:
Installs the Intel® Rapid Storage Technology (RAID) driver version 11.2.0.1006 for Intel® Desktop Boards.
This driver supports RAID 0, 1, 5 and 10. The driver should be installed after the operating system has been installed. F6 and RAID BIOS configurations need to be performed prior to installation of this driver for proper operation.
RST 11.2 supports TRIM on RAID 0 only on Intel Desktop Boards with the 7 Series chipsets.
Yet everyone is saying any 7 - series is fine....I'm doubting that comment though, why would Intel say only it's own boards?
This link for other boards suggests there is still no TRIM
