970m - 358 crashes with 32GB ram...

Anyone else experiencing this?

This is on a new laptop running a i7-6700k and 970m.
I can run 16GB just fine (2x8gb), but as soon as I put in more ram (4x8gb) the system crashes.
Ram passed windows mem test. Not sure what to do next.

Ubuntu15.10
Clevo P750dm-g
Displays: 3x1920x1200

I’ve no experience with Clevo products, however:

  • is the RAM which you are using qualified for that machine?
  • is its UEFI up-to-date?
  • does the crashing persist when using fewer monitors?
  • which nVidia driver version are you using?
  • have you tried other nVidia driver versions?

Convenient ways to install more nVidia binary driver versions than are normally available in Ubuntu:

OPTION #1

Ubuntu has their own nVidia GeForce graphics card driver ppa (maintained in part by one of the guys who maintain the ppa at xorg-edgers, OPTION #2 below):

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

After you have run the above commands, install an appropriate non-Beta version of the nVidia GeForce driver via Linux Mint’s ‘Driver Manager’.

To determine whether or not the chosen version of the nVidia driver is a non-Beta release, compare its version number with those of the ‘Linux 64-bit’ nVidia drivers displayed on nVidia’s GeForce web site:

Ubuntu Now Has An Official PPA For Graphics Drivers

OPTION #2

To get the latest nVidia GeForce graphics card drivers which are not yet available in Linux Mint 17.2 (or its Ubuntu contemporary); run the following commands in Terminal:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update

After you have run the above commands, install an appropriate non-Beta version of the nVidia GeForce driver via Linux Mint’s ‘Driver Manager’.

An unrelated tip re improving Unity’s performance:

Installing CompizConfig Settings Manager will allow one to disable Animations and Fading Windows.

Thanks John,
In short, 358 is the only driver that worked on my AvaDirect (Clevo manufactured) laptop.

  • is the RAM which you are using qualified for that machine? - YES
  • is its UEFI up-to-date? - YES
  • does the crashing persist when using fewer monitors? - I DON’T THINK SO
  • which nVidia driver version are you using? - 358.16 (latest)
  • have you tried other nVidia driver versions? - YES, AND THEY CRASH MY SYSTEM.

I added the PPAs and will try updating later.

Finally!
One of the system updates contained Nvidia stuff, and that has finally allowed me to drive multiple monitors with 32GB ram.

I’ve rebooted, came out of sleep mode, and generally using the system on 32gbs for over an hour.

The latest Ubuntu update for 15.10 broke things again. Once I removed half the ram, leaving 16GB, the system is stable again.
