Hello!

I searched many sites and found this tutorial:
http://www.overclock.net/t/1227636/how-t...ws-installation
And it worked!!! At least for my situation - RAID -> AHCI.

After some initial testing, I'm getting better individual performance from the HDDs, from 10 to 20% better at AHCI than RAID.
General latency is reduced too, which is very important for realtime audio recording of many channels.

As soon as I have more results I'll report.

Thanks again!
All the best!

So finally I found some time to mod the BIOS.

Here you can find the mods.
10101008.zip: This one is modded with iRST 10.1.0.1008 (TRIM in RAID 0).
11201527.zip: And here is one with iRST 11.2.0.1527 (TRIM in RAID 0).

Since brave found a solution to his problem, I don't think he would test these mods.
So I decided to post them directly.

EDIT: I did not change SLIC information.

Dear mr_nuub,

Thanks so much for your effort! I've just downloaded both BIOS mods.

Thanks to this forum I could solve my issues and work it with AHCI - my job was a huge live recording thru Dante, 52 channels (@24bits, 48kHz)! - my two data HDDs were not in RAID0, but I could assign half of the load (26 channels) to each one and it worked very fine!

But I still find RAID0 may be needed - like for 64 channels (@24bits, 96kHz)? Or for some video work I may do...

Now I'm in the middle/end of another work - so as soon as I finished it (in a couple of weeks), I'll try both mods you did and report - I can even provide some speed tests if it could be interesting/helpful for this forum!

Thanks again!
All the best,
brave

PS: what does it means "I did not change SLIC information" ?

SLIC means Software Licensing Description Table. This is a region in the BIOS, where the Windows Vista/7/8/8.1 product key and license information is stored.
I don't want to put you and other users into trouble, so I did not alter that information.

BTW: iRST 10.1.0.1008 could boost your performance, as it did with my X58 system (desktop).

Hi there!

Did you already test the modified BIOS files?

Best regards,
Mr nUUb

Hello Mr nUUb,

Sorry, but I'm still finishing that job... it will take me another week or two.

After that I will test your mods, I promise!!! Thanks!

all the best,
brave

Dude, what's going on? Did you try the mods?
