Unable to get TRIM functioning even with a TRIM enabled RAID ROM

Motherboard: Z68A-GD80 (B3)

Attempted RAID ROMs:
Universally TRIM modified Intel RST(e) RAID ROM v13.1.0.2030 with TRIM in RAID0 support
Universally TRIM modified Intel RST(e) RAID ROM v12.7.0.1936 with TRIM in RAID0 support
Universally TRIM modified Intel RST(e) RAID ROM v12.0.0.1783 with TRIM in RAID0 support

I’ve verified several times that the replacement ROM is indeed the correct. No issues flashing and no issues booting. I have tried a few other ROMs as well.
I also have all the latest system updates, BIOS version, motherboard drivers, and the latest Intel Rapid Storage Technology driver.

TRIM is still not working. Any ideas why?

I finally got it working!

The answer was here. Z68 boards only!

It is fine, that you found a solution for your problem yourself.
