Raid0 and TRIM Support on Intel 11.5 OROM and Latest v11.5.0.1184 RST Drivers ?

[Kain665]

Hex dump is useless, you're looking at certain LBAs that do not correspond to any specific NAND address. It's just how to FW presents the logical volume to the OS.

For all you know, these new drivers just tell the FS to wipe it's arse better - there is no way to check whether or not TRIM is working past the FTL.

[Kain665]

Considering that it's not working on Z68, I wouldn't be very confident that it's working on Z77. There's no real difference between the two, at least not something that would affect a software function such as TRIM. TRIM is an ATA command, it could care less what hardware it's going to as long as the drivers support ATA passthrough.

Fernando or anyone who can please help me , i have tried to Mod the latest Bios 0404 for my new Asus P8Z77-V LK but i keep getting a message while trying to flash the moded Bios that says " "Security Verification" warning , i dont have a ROG board on this Z77 chipset so cannot do the ROG flashback ( http://rog.asus.com/forum/showthread...BIOS-Flashback ) , this Mobo has only one Bios chip its not like my old Asus Rampage extreme x58 that had 2 Bios. So i have to be extra careful to not corrupt the Bios. I did succesfully Moded the Asus Rampage 3 extreme x58 Bios using your guide , i replace the OROM twice without any problem , its this UEFI Bios wich i dont understand so much , i have tried for 2 days and for the life of me i cannot mod this Bios correctly , can someone here with a good Soul help me and Mod this Bios 0404 for me with the latest intel Bios Raid OROM 11.5.0.1582

Motherboard is Asus P8Z77-V LK

Latest Bios 0404 here http://www.mediafire.com/?4h2kdhdnu5rkz56

Latest Official OROM http://www.mediafire.com/?jnvus6jdun15vas



Thank you so much in advanced , apretiate it.



Kind Regards Angelo.

latest RAID ROM .1582 + latest .1207 intel RST drivers are giving me much less performance...i flashed today with modded bios and i keep getting low read low write...weird...

I ran into the same problem with my ASUS P8Z77-V mainboard.
At least I succeeded with the update of the Intel RAID ROM module this way:

1. Take an USB flash drive, format it using the FAT32 file system and copy the modded BIOS onto it.
2. Rename the BIOS file according to the PDF file, which you got with the latest ASUS BIOS.
3. Shut down your computer, but don't switch off the power.
4. Open your Computer case, look into your mainboard manual and search for the "USB BIOS Flashback Button".
5. Put the USB stick with the modded BIOS file into the special BIOS Flashback USB port of the mainboard's Rear Panel and then hit the "USB BIOS Flashback" button for a few seconds until the BIOS flashback light starts to flash.
6. Wait until the BIOS flash light signal has gone out.
7. Start the computer, enter the BIOS and do your BIOS settings.
8. Remove the USB flash drive.

If you should not have an "USB BIOS Flashback" button on your mainboard, you probably have to wait until ASUS releases a new BIOS version with an updated Intel RAID ROM module of the v11.5 series.
If you don't want to wait for a new official BIOS, you or someone else may try to fix the checksum of your modded BIOS according to >this< guide.

Thank you , apretiate it the help , but i have found out that its immposible to flash my mobo with a Moded Bios file the normal way using asus flash 2 utility in bios via USB , i keep getting the message " Validation file failed " , the only way in order to succesfully flash this Moded bios its using the Asus Flashback Button method in the special usb relating to this procedure. My mobo does not have the flashback button as it is the cheapest Z77 board in the Asus Z77 line , so its a no go for me. But i have already contacted Asus Technical support with an inquiry for a Bios update with the included Latest File Bios Raid Rom 11.5.0.1582. i will wait a couple of days if i dont get an answer or a bios update i will have to pull some strings at Asus Headquarters Taiwan to my team mate Andre Yang and Master Shamino Peter Tan , i dont like to bother the masters they are always busy , i will use it and bother them at last resort eventhought we are great friends and belong to the same overclocking hwbot team Team PURE , but i have stopped profesional overclocking for over a year now , so no more trowing money to the wind on my part

FYI: I have done the Trim test very often. As long as I have done it with my Z68 chipset system, the Hex codes of the JPG file have always been at the same Offet and sector before and after the delition of the file. After having changed the mainboard to a Z77 chipset one the Hex codes of the JPG file were zeroed out within seconds. Additionally I have checked each time, if the Hex code of the JPG file has been changed to another sector by whatever, but it hasn't. The "Search" option of the Hex Editor couldn't find any part of the file.

For all you know, these new drivers just tell the FS to wipe it's arse better - there is no way to check whether or not TRIM is working past the FTL.

You are wrong. If the "new drivers" would tell the SSD Firmware to wipe the garbage better, why did it not do it on my Z68 board? The Hex codes of the deleted file were still there hours after having deleted the file, although the RAID has used exactly the same OROM/driver combination as with the Z77 board.

i went back to RAID ROM 11.5.0.1414 for some reason with .1582 sucked bad

when i had the .1414 i always have aprox 1200 of score then when i changed to .1582 i got 1031 and 1047 for 2 days so i went back and at the beggining was this with .1414

before just installed .1414 and after using .1582 for 2 days

i scored 1031 dont have the screen sorry


after i left it the weekend with .1414



so something going on here Trim or whatever it arranges data thats obvious

[Computurd]

I have been informed by an industry contact that TRIM in RAID 0 is in fact working and that it has been confirmed

[m.oreilly]

heck paul, i know it's working, i just want to know if intel really pulled some alchemy with magic drivers/win7 (other companies have pulled it off with 'special' hardware/FW and proprietary drivers, but MS wouldn't ok a whql)...or you are just verifying win8 is doing what it's supposed to...what's the story?

[Computurd]

I will provide more detail once i can. I am getting further news on it tomorrow.

[m.oreilly]

sweet! thank you

[radier]

I have checked some popular Intel boards and DP67BG, DZ68ZV already recieved latest OROM 11.5.0.1582

[Zaxx]

I will provide more detail once i can. I am getting further news on it tomorrow.

Can't wait to find out. Fingers crossed for Win7...

[chispy]

Thank you !

[Christopher]

Interesting. I have a DP67BG, and the last BIOS update did indeed add 11.5.xx. I might have to dig it out of the closet and give her a go.

[m.oreilly]

comp, i've been camped outside for the last 24 hours awaiting your reply. this spiderman outfit is itchy, and the Italian bakery will no longer let us (yes, us, as in the missus also wants to 'hear it first') use the facilities...we are down to our last napoleon...it's real good, but can you toss us a shred?

[DooRules]

ah ya crack me up bud, ever try standup m.oreilly?

[Computurd]

sorry guys im waiting on word back, i asked for 100% confirmation.

[m.oreilly]

is there going to be some sort of official announcement? i wonder why intel are not forthcoming? this would be big super news for existing older api enterprise, and point to future parity raid awesomeness...if unmap is working under server 2008r2 and win7. new server/win8:i kinda expect, but unless MS writes off on an included unmap driver, we will wait...

Why are you so excited?
You wrote, that you do not trust my test results regarding TRIM support within a RAID array. Now you are waiting impatiently for an information from a person, who knows a person, who knows persons, who say, that they know a lot about this topic.
Intel has already officially announced, that all RST drivers from v11.x.x.xxxx series up do support TRIM within a RAID0 (no word about restrictions regarding the OS or the chipset). You can read it, when you start the RST GUI of the last RST packages and open "Help" > "Introduction". Do you believe that? Why not?
As for me: I only trust, what I have verified myself.

[m.oreilly]

fernando, i love your tutorial on bios modding. it stands on it's own merrit.
attempting to decipher the state of nand, using a hex editor 'viewing' lba, and then saying the nand is trimmed, under an os that lacks the pertinent hints it's api would have to provide, is not very convincing, and neither are the bench results that have been posted. i'll wait...

Does anyone have a gigabyte f12 bios modded to include a version of 11.5 OROM that will enable functioning RAID 0 TRIM? Thanks for your help. I have no idea how this is accomplished so please excuse my ignorance.
