Thanks Martin.

So far i know CPU temps are only available since 4.11.for Ryzen so i will probably try that.
OTOH it runs very smooth and fast.

Dunno.

CPU tasks are more than 30 minutes faster than on win.

The question is should i upgrade to kernel 4.11 or 4.12 ?

Mike

Ryzen support is in 4.9.10 onwards, so 4.10 or 4.11 is more than enough. The main thing to keep updated is the bios to get microcode updates and other fixes.

I'm running Debian with the 4.9.30 kernel which seems to be the latest they have at the moment.

Good comments there, especially for including CPU microcode updates. I have those updated via the kernel rather than re-flashing the BIOS. (A BIOS re-flash is only done if the BIOS doesn't work in some way...)

At the moment I'm running the 4.10.17 kernel. That series includes improvements to IO scheduling that improves responsiveness during maxed out disk writes. See "Linux kernel 4.10 Improved writeback management" (Throughput should remain the same.)

Kernel 4.11 has only recently been released... Good to try if you wish to be on the "cutting edge". I would only jump there if there is some new 'must-have' feature. Otherwise, let things settle for one kernel cycle and follow the main distros. You'll still be ahead of everything else!


A good fun list for what is new is listed on "Linux Kernel Newbies":

• (Kernel 4.13 is now being worked on: See Phoronix for "Some Of What You Can Look Forward To With Linux 4.13")
  
• (Kernel 4.12 has just now been released - 2 July 2017. See Phoronix for "New Features Of The Linux 4.12 Kernel")
  
• Linux 4.11 has been released on Sun, 30 Apr 2017
  
• Linux 4.10 was released on 19 Feb 2017
  
• Linux 4.9 has been released on Sun, 11 Dec 2016
  

Kernel 4.11 is already up at version 8 so that is going to be safe enough to jump up to for picking up the latest tweaks and developments.

But really, the only motivation to move up the kernels is if/when there is some must-have feature in there that you wish to take advantage of. Usually, that would only be if there is some new support for whatever new hardware, especially so for new GPUs. (For example, my jump to 4.10 skipped quite a few versions in between.)

Or just go with whatever is most easily supported.



Hope that is of interest,

Happy cool fast crunchin',
Martin

Hey Mike, how many Ryzen systems did you build? Your 3 systems all show up as Ryzen 1800X. I think that BOINC is probably confused. I looked at 5735690 and it shows up as a 1800X but your CPU tasks show a FX-8350 in stderr.txt. BOINC is confused.... right?

Hey Keith.

All hosts in my list are the same computer.
Just haven reported much on windows yet because i switched to Linux during the outage.

IIRC Raistmer removed the CPU Frequency for windows because it wasn't always correct.
Urs still uses this feature for his Linux apps.

Thanks Brent, I suspect it is up to the individual app to report the CPU frequency and not specific to OS platform.

I do know that some apps report CPU speed some don't. Whether that is a limitation of the code type used (vX SSSe, AVX, etc)I don't know, but would think it is just what the individual programmer add in.

AS for changes, it could be Turbo mode, etc, or changes made. He would have to answer that by saying if he made changes, or if it is dynamic.

EDIT: Just checked my Linux CPU apps, SSE3 MB/AP, SSSE3 and AVX MB/AP are all reporting CPU speeds.

Brent, would you know the answer to my previous question to Mike about reported frequency in stderr.txt?

I think that would be from swapping drives around.

Hi Mike. Welcome to the Ryzen World. Curious how your stderr.txt output for your CPU run tasks report CPU frequency. Is that because of the Linux platform... or because of the Linux SSE4.1 app? I see you are running Anonymous and wonder why I never report CPU frequency on my Anonymous platform. I know that the stock app reports CPU frequency for Intel processors but I don't believe I've ever seen CPU frequency reported for AMD processors. I also thought it was because AMD doesn't report that or the app doesn't expose it for AMD processors.

Also noticed a couple of different reported CPU frequencies for your CPU tasks. The majority ran at 2200 Mhz but a couple ran at 3600 Mhz. Are you running stock speeds with no overclocks and letting the Core Performance Boost do its thing on 1 or 2 cores when it can?

Thanks Mark for your reply.

I see you are running the AVX version.
I suggest to try the SSE 4.1 version.
Check my results.

Since my old thread autolocked already i create a new one.

I successfully installed my Ryzen System yesterday.
As precaution i upgraded Mint 18 to kernel 4.10 before.
I only had to update the GPU drivers to get it work.

System is as follows.

Ryzen 1800X
Crosshair VI Hero
16 GB Gskill 3200 CL 14
AMD R9 380

All is running fine so far.
The question is should i upgrade to kernel 4.11 or 4.12 ?
Anyone running those kernels already ?

Thanks in advance.
Mike
