Samsung 830 256gb, no intel x79 AHCI Drivers? - Page 2

You've got a few options, but first let me ask you something: you said

Are you comparing two different machines or did you borrow the 64GB SSD and used it in your X79 system ? Is your other machine also an X79 system ? If you are testing the SSDs in different systems, a whole lot of things can be considered, but especially one: if your other machine is not X79 based, it might be using Intel's RST, which some people claim is faster than RSTe. You can also use Intel's RST on the X79 platform, although it is not officially supported. You'll have to force the driver installation, and you won't have an icon in the tray. I don't know how it's done, but you can look it up, ther are instructions on how to do it.

Other than that, if you tested both SSDs in your X79 system, you can go through this check-list:

1. Like steve-n said, update to the latest Intel® Chipset Device Software;

2. Make sure you're using the latest RSTe drivers too. One previous version (the one that Asus lists on its site as the latest) gave me two BSODs. The latest on Intel's site is listed as being 3.1.0.1085. Click here. Once installed, go to the icon in the tray and click the Help button annd then the About button, you should have version 3.1.0.1068 installed (yes, it's not the same version you downloaded, because Intel has a weird version numbering, my guess is that the package includes a version for the C600 with SAS enabled and this 3.1.0.1068 version with SAS disabled for the X79 platform).

3. Did you clone the boot drive ? You can try making a fresh Windows install.

4. Do you have AHCI enabled in the BIOS ?


Hope this helps!

I've already told you what the problem is, you're trying to install Intel's RST drivers, but those are not for the X79 platform, you need to install RSTe. If you really want to install RST, you need to manually force the installation. As I said, some people claim Intel's RST drivers provide better performance on the X79 platform compared to RSTe.

Also, as I have said before, comparing benchmarks of one SSD on one system, in this case a Z68 system, with the performance of another SSD on another system, in this case an X79 platform, is not going to get you anywhere, especially given that Intel's RSTe supposedly provide worse performance.

It's impossible to know from the screenshot.

What boot drive did you have before that one in your X79 system ? Did you clone it to the SSD, or did you do a fresh install ?

Well, install one driver at a time now. Possibly forget about installing the SATA driver. Just use the default one.
