Hello UVoor,

Thank you for posting on the Intel® communities and for the System report provided.

In order to have a better understanding of the environment and figure out what it is happening, could you please provide the following information:

1- Was there any hardware or software change prior, during or after the issue happened?

2- Please provide details on how you disabled Acceleration and the steps you have tried to re-enable it.

When you try to enable back, is the option grayed out?

3- When exactly is the error "0xA0050055" being displayed? For instance, when clicking on "Enable acceleration" on the Intel® Rapid Storage Technology (Intel® RST) User Interface. Please provide details.

4- Please provide full screenshots of the following in order to check the current status and options available:

4.1- Intel® RST User Interface >> Status tab

4.2- Intel® RST >> Manage tab

4.3- Intel® RST >> Accelerate tab

4.4- Screenshot from Windows Disk Management.

Dear Andrew, Thank you for your interest in the matter and support. With regard to the question I can report as follows: 1. The reason I disabled the acceleration is that I was having issues with the computer freezing up and BSOD. However, this did not help with the problem. Trying to switch acceleration back on through the interface did not work at that stage already. I then did further testing and Windows Memory Diagnostics was signaling errors with the RAM modules. I changed those, and while the computer is more stable now, this did not help with the issue of acceleration, which still does not work. I have been keeping the computer updated as directed by Windows software, Dell Support Assist and Intel Driver Support Assist. 2. I deactivated acceleration through the Intel Rapid Storage Technology interface, “Performance” tap. I tried through the same tap/interface to activate it again. The option is not greyed out and all drives show green check marks. After pressing Ok in the menu to accelerate the system disk (see below screenshot) the error code comes up after a few seconds. 3. and 4. See screenshots below Your support is very much appreciated. Kind regards Uwe Sent from Mail for Windows 10

Hello UVoor,

Thank you for your patience in this matter.

We would like to recommend the following steps:

1- Ensure the BIOS settings are correct for acceleration, you may check with DELL™ support regarding how to access the BIOS and the correct settings.

2- Try to uninstall the current Intel® RST driver and re-install using the customized driver provided by DELL™. Based on your system model (DELL™ XPS 2720), you may find the driver on the DELL™ website in the below link: Intel Rapid Storage Technology Driver, Version: 14.5.0.1081 ,A00*

As a second option, you may try our Intel® RST driver. However, we recommend using the driver provided by the system manufacturer or via Windows® update to eliminate the potential impact caused by loading non-customized drivers. System manufacturers regularly customize Intel generic drivers to meet the needs of their specific system design. In such cases, use of the Intel generic driver update is not recommended.

Based on laptop datasheet* and chipset model (Intel H87 Express Chipset), the Intel® generic driver you may try from Intel® is version 14.8.16.1063

If the issue persists, please provide the following information:

1- Was any change performed on the BIOS? Were you able to check/set the correct BIOS settings?

2- Please provide a new System Report for Intel® Rapid Storage Technology after trying to uninstall and install the Intel® RST driver.

3- Please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread.

3.1- Open the application and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".

3.2- To save your scan, click Next and click Save.
