XPS 9560 Speed Shift - when will Dell enable via BIOS update?

Still waiting for Dell to update BIOS to enable SpeedShift on the 9560 and 9550 premium XPS laptops.

When will this happen?

Thank you for your feedback and question regarding Speed Shift on the XPS 15 9560. I'll take this up the ladder and will reply back with an answer as soon as I can.

Agreed - It would be nice if we could use all features of our CPU.

Come on Dell, change the BIOS to show the speedshift setting and give us what we paid for.

Yes this would be a good idea.

If you want us to keep buying your stuff, you can't abandon us so quickly. Enable this important extra in BIOS and do yourself a  favor.

Dell engineering has advised me today that Speed Shift will not be enabled on the 9550 and 9560.

I know it's not that best news but thank you for your questions and feedback.

So we are able to enable is ourselves via a bios hack with great success but your engineering team will not enable it even though it is so easy to do it makes dell engineering look more pathetic than your quality control.

Absolutely pathetic,.

Another reason to avoid Dell.

your engineering team need to wake up and enable a default feature.

Justin - Thanks for taking the time and effort to reach out to the Dell Engineering team.

Do you have any insight or a personal view on why Dell declined to enable SpeedShift?

Thanks again!

Thanks for the update, Justin C. I will make sure the message the engineers have sent will be received by as many people as possible.

For what it's worth... With real world speed comparison.

Compiling my project without SST activated takes 28.5 minutes

with SST: 26 minutes.

I was wondering why it was that my Gigabyte Aero 14 with a i7-6600HQ was that much faster than the Dell XPS 15 9560 with an i7-7700HQ, while I haven't figured out everything yet, the Aero 14 has SST enabled by default.

I hope Dell will reconsider.

(the Aero 14 takes 24 minutes to compile that same project, it's something unique to Windows, as on linux the 9560 is 1 minute quicker than the Aero 14)

I am also making my point by putting this in EVERY single review I can find, you can always tell the lazy sods to spend 3 minutes enabling it in the next BIOS to save face.

Fortunately, there are a few easy ways of enabling SpeedShift. Enabling a BIOS switch would have been the most elegant. A simple introduction is at this link:
