Precission Mobile Workstation m5510 very slow and laggy

I noticed massive performance issues lately - thought it's caused by TB16 dock, stripped bloatware, run some benchmarks - only then I noticed the multiplier was fixed, stuck at 8x no matter what - my laptop CPU was running at 800MHz at all times. It's a shame that DELL put this silent und undocumented safemode in their top tier premium mobile workstation. It have cost me so much time to find the cause!

Wow.  I had this exact issue, but dumped the machine because I could never find a solution.

We had this same issue with a Precision 7720 laptop.  Here is the solution:  https://www.acarte.com/2021/01/07/extremely-slow-performance-on-dell-precision-or-xps-laptop/

Hope this helps!
