Dynamic Storage Accelerator setting disappeared from RST software on Windows 10 x64 10586.164

[DPokr1]

For some reason Dynamic Storage Accelerator setting has gone from RST software 14.8.0.1042 on Windows 10 x64 10586.164. It was definitely there before 10586.122.

i7-4770 + Z97 + DSA enabled in BIOS.

Could anyone else confirm this, please?

Do you have that option with previous Intel® Rapid Storage software versions?

Just to be sure I have reverted RST back to vendor's 14.5.0.1081 (driver and software) and even re-flashed BIOS, but with no luck. I'm pretty sure it was there before either with 14.8.0.1042 or 14.5.0.1081 or both (I got screenshot), but not anymore after 122 and 164 updates.

It appears to be an issue after windows update. You may need to run system restore to go back to an earlier date or wait for future Intel® Rapid Storage software releases.

Ok, thanks. I'd better to wait either for a new RST release or further Windows updates - one that would fix that first.

Sure, no problem. Please keep on checking https://downloadcenter.intel.com/default.aspx Drivers & Software for any driver update.

Or Try my solution when you waiting for new driver :

Good day to you

Thank you for the advice. In my case I found that for some reason Windows/RST has stopped correctly working with C-states. Once I switched the CPU C-states option in BIOS from "Auto" to "Enabled", Dynamic Storage Accelerator magically began working once again. It was definitely something between BIOS, Windows and RST after their updates.
