Thank you very much for joining the Intel® NUC communities.
Just to let you know, I ran the XTU on the Intel® NUC6i7KYK we have in our lab, and I also see the same value for the EDRAM frequency. So, I will do further research on this matter in order to confirm if that means that it is disable or that it is not working; and if it can be overclocked with the tool.
To answer your second question, the Intel® XTU software interface exposes a set of robust capabilities common in most enthusiast platforms along with special new features available on new Intel® Processors and Intel® Motherboards, so it should work just fine with the i7-6770HQ processor or any other Intel® processor and it should report correctly.
All the known issues are reported on the link below, I verified that document and there is no information about a problem between the tool and your processor or with EDRAM:
As soon as I get any updates I will post all the details on this thread.
Any further questions, please let me know.
Thank you for the feedback and support!
I recently noticed this in my linux kernel log which may help:
[ 2.557021] [drm] Initialized
[ 2.926984] [drm] Found 128MB of eDRAM
[ 2.927785] [drm] Memory usable by graphics device = 4096M

I'm guessing that's good news, and a way to confirm it? drm seems the i915 GPU driver by intel.
Isn't it XTU known issue? I use Dell NB got the same status.
Hi, TMASHP and Melaniess. You are welcome. Thank you very much for providing that information.
I just received an update from the research we are doing on this regard and based that information I just wanted to let you know that the BIOS team is currently looking into this scenario, but according to them it may take several weeks until they can provide a possible solution for this matter.
Let me apologize for any inconvenience.
Any questions, please let me know.
This issue has been addressed on latest Intel@ XTU, can you please try it and report back your results.
