It says the HDD is a 6GB SATAIII. I am going to check that since i hooked into the SATA II port.

My recommendation for your Intel HM76 AHCI system is the 64bit Intel RST(e) driver v12.9.0.1001 WHQL.

Happy New Year!

Intel obviously has fixed some additional bugs with the release of the RST(e) drivers v12.9.0.1001. The matching OROM version will be available soon.
General statement:
Within the start post of this thread I have written, which drivers I recommend to try, if the users are searching for the "best" Intel AHCI or RAID driver. Since each hardware configuration and the users PC usage preferences are different, everyone has to find out himself, which Intel RST/RST(e) driver version definitively is the "best" for him resp. for his system.

Newbie here

Can someone suggest Intel RST ROM version for Dell XPS 8300 H67 / 6 Series?
Dell latest BIOS has RTS v.10.0.0.1046.

I need an update to recognize drives over 2tb.
Should I stay with v.10.1.0.1008 to be safe and stay under 100 KB size?

UBU output:
1 Intel RST(e) OROM and EFI SataDriver
OROM IRST SATA - 10.0.0.1046
EFI IRST SATA - Not present
2 Intel OROM VBIOS and EFI GOP Driver
OROM VBIOS Sandy/IvyBridge - 2119
EFI GOP Driver - Not present

Thanks in advance!

If I were you, I would replace the Intel RAID ROM v10.0.0.1046 by the v11.2.0.1527 and use the Intel RST driver v11.2.0.1006 WHQL. Reason: This way you can expect the best RAID performance.
Since your mainboard has an AMI UEFI BIOS, there should be no space problem regarding the >100 KB sized OROM.
EDIT: Furthermore an Intel RAID ROM v10.5 or higher is needed for the support of > 2 TB sized RAID volumes. So you would not get the desired feature by inserting the Intel RAID ROM v10.1.0.1008.

Fernando

Thank you Fernando,

I'll try your suggestion.

Can I safely downgrade Intel RST driver from v12.9.0.1001 to v11.2.0.1006 ?

Yes you can, but I recommend to read the chapter "Switching from Intel RST to RST(e) drivers and vice versa", which you can find within the start post of >this< thread.

Hello Fernando,
I have a new BIOS that I plan on replacing the Orom with this one.
Especially modified Intel RST(e) RAID ROM v12.9.0.2006 with TRIM in RAID0 for X79 systems.

What driver for will give better raid0 performance? RSTe 3.6-3.8 or RST?
If RST, have a link?
Also, what F6 driver is best for OS install with this Orom?

Hi,

when you have the possibility to switch inside the BIOS to dev. 2822 (RST instead of RSTe) I would recommend that because with the modified OROM you either need the original RSTe 3.xx driver or the specially modded driver 12.xx. Any way in both cases you will not be able to install and use the complete software console (somehow the console knows that there is a modded OROM working and when you enter the "settings" page it crashes). That means you will not be able to adjust all the performance features. In my case using the modded RST driver gave me faster booting and TRIM support, so if you need to go the "12.9.0.2006 modded for X79" - way I recommend the modded RST driver.

Best regards hanson

Thank you for your response but your suggestion contradicts a lot of what I have read here. I am pulling my hair out trying to figure this all out. I thought this would/should be a rather simple process, but so far I have yet to wrap my head around it 100%. I have read so many old posts and new posts that I may be combining info that is not relevant (information overload).
It would be nice to see sticky's, sorted by chipset with what OROM,F6 driver and OS GUI/driver combo works and what is expected performance of those combo's. e.g., trim in raid0, good read performance, GUI crash ect.

I have an asrock x79ex4 and thought that IRSTe drivers were designed for that chipset only. E being enterprise/enthusiast =x79/c600. Am I wrong?
I ask because, I seen these posted.
Download Links to the actual Intel RST(e) Drivers v11/12/13 Series and their RST(e) Software:
(These Intel RST(e) driverpacks contain an AHCI/RAID driver named iaStorA.sys and additionally an SCSI filter driver named iaStorF.sys. They are designed for actual Intel chipsets except X79.)


In my device manager/storage controllers/c600 raid controller/ properties/details/hardware id's I have
PCI\VEN_8086&DEV_2826&SUBSYS_28221849&REV_05
PCI\VEN_8086&DEV_2826&SUBSYS_28221849
PCI\VEN_8086&DEV_2826&CC_010400
PCI\VEN_8086&DEV_2826&CC_0104

1. does 2826=rste and 2822=rst?
2. are these numbers "hardware locked" or can these numbers change if OROM is flashed?

A quote from Fernando "Usually X79 RAID0 systems have a better performance, when the SATA RAID Controller is managed by an Intel RST(e) RAID ROM v11 or v12"

what combo OROM, F6 driver and GUI driver will give me good performance, trim in raid0 and a working rst console?

1. does 2826=rste and 2822=rst?
Yes, if you mean, that the default DEV_2826 RAID Controllers usually are managed by the Intel RSTe RAID drivers (v3.x.x.xxxx series), whereas the default DEV_2822 RAID Controllers are either managed by the "classical" RST driver named iaStor.sys (latest is v11.2.0.1006) or by the RST(e) drivers from v11.5 up (I name them RST(e), because they use an additional SCSI filter driver like the v3 RSTe drivers).

2. are these numbers "hardware locked" or can these numbers change if OROM is flashed?

The DeviceID is "hardware locked", but can be changed by a special system BIOS component. If you just flash a BIOS containing an original DEV_2822 RAID ROM instead of the default DEV_2826 one, into an X79 BIOS chip without the dual boot option, you will automaticly get a BSOD while booting.

This question should be answered by a user with an X79 RAID0 system.

Hello Fernando,

is your recommendation of #1 only valid/important for raid-systems, or single-systems, too?

I use lenovo T500 with ICH9M, so you recommend 11.2.0.1006

I have tried all RST(e)-drivers (incl. 13) and don't notice any issues.

So anyhow should I use 11.2.0.1006? Or maybe there will be some advantage in one of the 12.-versions, because of some bugfixes?

@ ole258:
My recommendations, which I have layed down within the start post of this thread, are valid for AHCI and RAID systems.

You should use the driver, which works the best for your system. The differences regarding the performance are negligible.
On the other hand the user should keep in mind, that Intel doesn't optimize their AHCI and RAID drivers for chipsets, which are outdated since a long time.
The Intel RST driver v11.2.0.1006 is the last one of the conventional RST drivers, that means all registrated bugs of this conventional RST series had been fixed with that version.
The newer Intel RST(e) drivers from v11.5 up have a totally different functionality, because they use an additional SCSI filter driver. Intel is still focussing their work on eliminating the bugs they got by introducing this SCSI filter driver concept.
