I am new here and need some help. I have two Samsung 840 Pro SSd's I would like to RAID 0. My BIOS version is 1402 and I from looking around I don't think that it supports trim in RAID 0. It looks like there is a way to enable it someway by flashing a modded BIOS/ROM somehow. I am not totally new to modded BIOS's as I have purchased (donated) modded BIOS's for my MSI GT70 from a guy named Svet on the MSI forums so I have at least a little experience. Can someone help me out? I would be willing to donate in a similar way to how Svet works.

Thanks for the welcome! Glad to be here! I read the first post, downloaded the AMI non-UEFI MMTOOL v3.26, the original BIOS from Asus. I plan to reinstall Windows 10 after I mod the BIOS (if I can)... Where would I find the proper PCI ROM modules that will enable trim support in RAID 0 using the Intel ICH10R and maybe even the Marvell 9128 if it exists? Is there a guide on the use of the tool for inserting the PCI ROM modules? Are there any suggestions for modding that would lead to better/increased performance? Thanks in advance!

It looks like the first download link doesn't work and the 'Mirror' to a OneDrive does. I just want to make sure I and getting the right "Universally Trim Modded" Intel RAID ROM v11.2.0.1527 because there are a lot of filea in that location. Is it called "Intel-RST_RAID_ROM_v11.2.0.1527_TRIM-mod-acc-CPL0"?

Thanks! I am thinking I will also update the Marvell RAID controller. Something strange though, when I open up the newest BIOS file from ASUS and find the appropriate Marvell Option ROM the DeviceID is 9123 but in the motherboard manual it calls it the Marvell 9128. I notice that there is a device ID that is called 9128. I would just think that they would match. Any thoughts?

OK thanks and done. I have saved the new modded BIOS and will try to flash it tonight. Does the name of the BIOS file make a difference, like if I call it a descriptive name will the BIOS be called that or does it retain the same version info somehow (in my case 1402)? What is the best (safest way) to flash it ? Should I do it using the Windows 'ASUS Update Utility' or the 'Alt + F2' EZ Flash 2 onboard utility?

So far I have modded version 1402 of the BIOS ROM Module for the ICH10R to "8086-2822_v11201527_mod-for-TRIM-in-RAID0.bin" and the Marvell 9128 ROM Module to "1b4b-9123_1001038.bin". Per your advice I have replaced the Windows 10 in-box Intel driver with "64bit Intel RST AHCI & RAID driver v11.2.0.1006 WHQL". Should I also replace (if it exists) the Win 10 in-box driver for the Marvell 9128 with a different version like I did for the Intel ICH10R? The latest driver from Asus for the Marvell 9128 on the x58 Sabertooth is version 1.2.0.1002 but it looks like there is one here >64bit Marvell 91xx-92xx AHCI & RAID drivers v1.2.0.1035 WHQL< that says supports TRIM.

I don't have anything on them right now but I plan to reinstall Win 10 when I am done removing/replacing drivers in the Win 10 image so in the future if I do decide to use them then install and BIOS will already be set up. I just was wondering if I should be matching up the option roms with the appropriate matching driver for the Marvell 9128 just like I did for the ICH10R.

You can update the Marvell 91xx SATA ROM of the BIOS (or let the UBU tool do the work)

I don't understand what you mean here. I used the "AMI non-UEFI MMTOOL v3.26" to replace the PCI option ROMs for ICH10R and the Marvell 9128. What is the difference between me updating the Marvell 91xx SATA ROM and letting the UBU do the work? I guess I don't know what UBU is. =)
