After having built a fesh RAID0 array using the Intel EFI RAID SataDriver v184.108.40.2065 and done a fresh install of Win8 x64 onto my Z77 system, I can confirm their findings:The newest Intel RAID ROM v220.127.116.115 definitively does support TRIM in RAID0, but the RST(e) RAID drivers v18.104.22.1686 WHQL do not support this feature at all!
Just a simple downgade of the Intel RAID driver to v22.214.171.1242 brings the TRIM in RAID0 feature back.
So these test results explain, why the P67 and Z68 users, who had flashed my "Especially modified Intel RAID ROM v126.96.36.1995 with TRIM in RAID0 for P67 and Z68 systems" and installed the v12.5 drivers, didn't get TRIM in RAID0 working.
As a consequence I will reactivate the download links to the especially modified Intel RAID ROM modules v188.8.131.525, since they obviously do support TRIM in RAID0, but the users have to use the Intel RAID drivers v184.108.40.2062.
i tested my z68 m4e-z with RAID ROM v220.127.116.115 and irst 18.104.22.1683, but NO trim for me..
correction: with orom 8086-2822_v12501815_mod_for_P67+Z68.bin TRIM does work..
Fernando gave me the correct satadriver to extend the bios-options of the m4e-z:
but unfortunately, there's still no option to do an (u)efi install:Edited by jeroompje - 4/1/13 at 2:04pm
