Ryzen so far…

So my first iteration ended in a failed BIOS update…  Now I have a fresh MB.

Iteration 2 – disable everything

Ryzen machine is running pretty stable now with a few tweaks.   I was getting some memory paging bugs but one of things worked around it:

  • Moved from 4.10 (stock zesty) to 4.11 mainline kernel
  • Remove 1 of my 2 16 GB sticks of memory
  • Underclock memory from 2400 -> 2133
  • Re-enable VM Support (CVM)
  • Disable the C6
  • Disable boost

It was totally stable for several days after that..

Iteration 3 – BIOS update

Trying to have less things disabled (or more specifically to get my full 32 GB of ram) I did the latest (7A37v14) BIOS update (with all cables not important for the update removed).

Memtest had also intermittently shown bad ram… but I can no longer reproduce…  Both sticks tested independently show nothing is wrong..  Then I put both back in and it says it’s fine.

Part of that was resetting the settings above and although it was more stable I was still getting random crashes.

Iteration 4 – Mostly just underclock the RAM

  • Underclocked 32 GB of  memory from 2400 -> 2133
  • On 4.11 kernel mainline kernel with Nouveau drivers (previously on Nvidia prop. driver, but didn’t support 4.11 at the time)

So far it’s been stable and that’s what I’m running.

Outstanding things

  • CPU Temperature Reporting on Linux is Missing.  (AMD has to release the data to do so – see some discussion here.  That is a community project, posting there will not help AMD do anything)
  • Being coreboot friendly with these new chips
  • Update BIOS from Linux?
  • Why is VM support disabled by default? (It’s called SVM on these boards)
  • MSI please document/implement BIOS recover for these motherboards

Overall

Ryzen 1700 is a pretty powerful chip.  I love having 16 threads available to me (VMs/Compiling faster is what I wanted from ryzen and it delivers)   Like many new products there are some stumbling blocks for earlier adopters, but I feel like on my hardware combinations+ I’m finally seeing the stability I need.

*Stability testing was just leaving BOINC running (with SETI and NFS projects) with Firefox open.  And doing normal work with VMs, etc.

When should i386 support for Ubuntu end?

Are you running i386 (32-bit) Ubuntu?   We need your help to decide how much longer to build i386 images of Ubuntu Desktop, Server, and all the flavors.

There is a real cost to support i386 and the benefits have fallen as more software goes 64-bit only.

Please fill out the survey here ONLY if you currently run i386 on one of your machines.  64-bit users will NOT be affected by this, even if you run 32-bit applications.
