If you want to test an Intel RAID driver of the v12 series, I recommend to chhose the 12.9.4.1000 one. It is the latest and best of that series (best matching Intel RAID ROM/EFI RaidDriver: v12.9.0.2006).

---

Thank you for pointing me in that direction. That will certainly avoid me a lot of 'guess & try' work. I'm currently doing an extensive test on my audio system with 12.9.4.1000 and so far the results are great (only one audio drop-out in 30 minutes of intense multi-track recording).

For sure it is possible and if you use the UBU tool (look >here<), it is very easy and very safe.

I've also downloaded and given a first try to the UBU tool. It's an amazing piece of software (my thanks goes to the developper SoniX too).
And now the obvious question ;) in my particular system can I expect some benefit of updating to the latest Intel ORom or downgrading to v11.2.0.1527 (for example) to match the 'best' 11.2.0.1006 RAID driver?
I've learned a lot so far on this forum ! I like that :)
Thank you
Bob

Yes, you can expect some benefit, when the Intel RAID ROM matches the Intel RAID driver.

My current tests following your advice in your previous mail have demonstrated this clearly on my system.

With a Memphis Pegatron motherboard (Hewlett-Packard 2AF7) equipped with an Intel H87 chipset [Lynx Point] would you recommend I go upwards or downwards in RST driver and matching ORom versions?

If I were you, I would start with the Intel RAID driver/OROM combo v12.9.4.1000/v12.9.0.2006 and then test the v13.2.4.1000/v13.2.2.2224 combo.
If you should get an explicit winner regarding performance and stability, I would stick with that one, but if you should not be really satisfied by both of them, I recommend to test the combo v11.2.0.1006/v11.2.0.1527.

Once again, thank you very much Dieter for this precise and really useful answer. Your experience is valuable and is a great time and money saver!

As I've mentioned earlier this day, I'm quite happy with the v12.9.4.1000 RST driver combined with the v12.5.0.1815 OROM already installed on my machine. The results are quite amazing. I will keep on testing in a professional environment this week and will probably stick to this combo. Otherwise, I will follow the other steps you've suggested.

For those who might be interested, I just would like to add that my main issue was to get an RME FireFace 800 firewire audio interface operate multitrack recordings without audio dropouts on an Intel RST RAID system. I've realized with your help that new is not best, when it comes to Intel RAID Drivers. They do have to match the Optional RAID ROM build in your machine BIOS !

I would not have been able to sort out this problem without your precious help.

Thank you and all the best!

Hi Dieter!

After 2 days of intense testing, I confirm that my problem has been solved by installing the v12.9.4.1000 driver without attempting to update my OROM version which is very close to the one you suggested.

However, I'm still curious to see what extra performance I could get by actually updating it from OROM v12.5.0.1815 to the specific version you suggested i.e. v12.9.0.2006.

I had no trouble to create a BIOS file with UBU, but, as many others, I'm stuck with a validation error which prevents me for going further.

Do you have any advice about how to update a HP Pavillion Desktop with Intel H87 chipset? I've read many things about Asus or GigaByte, but not much about HP. Did I miss some usefull details on this forum :) ?

Hello!

I want to install Windows 10 x64 on my PC but I don't know what about Intel RST driver?
On Windows 8.1 I used v13.1.0.1058 WHQL - does this driver will be compatible with Windows 10?
What about default Windows 10 AHCI driver - maybe I don't have to install v13.1.0.1058 WHQL?

MSI Z77A-G43, i7-2600k 3.40GHz, 8GB RAM, GTX 970 4GB

Thanks!

For the RIVE, would you recommend the default MS AHCI, or RSTE, or RST? And which version?

I'm NOT running raid. And none of them are the system drive.

Hi,

I am running a 620 GB RAID 0 volume and a 120 GB SSD on my Intel Controller. I have a separate back up drive. I also have a Marvell controller available on my motherboard. I have my Win 10 installed on my SSD. I keep my apps, games and data on my RAID volume. How should I configure my setup to get the best performance out my SSD and RAID volume? My current configuration is below. I apologize if this is the wrong thread.

System Report

System Information:
OS name: Microsoft Windows 10 Pro

Intel® Rapid Storage Technology enterprise Information:

I used AN SSD Benchmark and tested 13.1.0.1058 (officially support Z77 version), 14.8.7.1051 (forced Z87 option in Device Manager) and 14.10.0.1016 drivers (forced Z100 option in Device Manager). 13.1.0.1058 had the best performance (marginally of course) and the lowest response times, except for 4K-64thr performance, which was the highest with 14.10.0.1016 (marginally by 5MB/sec) drivers. I was very careful to reproduce the exact environments for each test.

Thing is, I also tested game load times and 14.10.0.1016 provided the snappiest performance. I think there's more to AHCI driver differences than just Read/Write/Response Time differences. Maybe 14.10.0.1016 drivers can apply these "newer features" on Z77 motherboards when Z100 option is forced through Device Manager) ? Maybe 14.10.0.1016 drivers are better optimized for Windows 10? I think 13.1.0.1058 use WDDM 1.1 and 14.10.0.1016 drivers use the newer WDDM 2.0, which is better optimized due to reduced CPU overhead.

What new features do Z87, Z97, and Z100 Intel RST AHCI drivers (like 14.8.7.1051 and 14.10.0.1016) have that Z77 (13.1.0.1058) Intel RST AHCI drivers do not?

With Z77 Chipset you can install 8-series family driver manually from the latest 14.8.0.1042. There are no AHCI differences between 7 and 8 series in driver. You only have to select the driver manually to install, because of the different name.
