RC6/RS2 Issue Z8350 Cherrytrail

For over 1.5 years we have been experiencing Lock-ups, freezes, Bluescreens due to RC6 Issue as part of Render Standby RS2.

To overcome this we disabled RS2, But this has significantly reduced Battery, which is causing another issue for long duration gameplay.

We're at much of an in-pass regarding runtime, vs getting errors on devices

Some Questions:

  1. Is Intel aware of issues on RC6, as I have several forums talking about RC6 issue on various Intel Platforms.
  2. Do you on any fixes, I have seen a discussion on disabling RC6p(deep RC6), RC6pp
  3. Could RC6 + RS/2 have a dependency on C-state (which we disable ALL c-states to fix another known issue) given they are both power management features. Is it possible to only disable C-state 6 which is what intel report the issue on, so we could test? Can you confirm there is no dependency with Intel?
  4. Is this now a known intel issue (wasn't in 2017). E.g is there a 2018 known issues document available.
  5. Do Intel have any suggestions
  6. Any documents covering this issue on Cherrytrail Platfrom.

ianfox04: Thank you for posting in the Intel® Communities support.

 

 

Are you a developer or designer developing a project?

 

Could you describe the meaning of RC6 and RS2?

 

What is the model of the device you are referring to?

 

Could you please clarify and provide further details about stop error codes and other Windows errors?

 

 

Regards,

Hi Alberto,

i am neither a developer or designer.

We manufacture & sell Windows 10 8", 10", 12" Tablet using Intel Cherrrytrail Z8350 CPU's

One of our customers uses our 8" Tablet for Bingo, Casino play, utilizing low GPU, CPU Use but for long duration >8hrs On.

We continue to see unit hang, freeze, lock-up with RS2 Enabled.

With RS2 Disabled lock-ups, hang, freezes disappear but battery is reduced significantly due to power saving option 'off'. Not good for long battery play

Errors reported are rc6 issue, which is basically a sleep state in Intel Platform

RC6 power saving feature in firmware code In Intel Platforms

RS2 Render standby power saving with low GPU Usage
