Recommended motherboard (Hardware) real time desktop Lv2014

[Rgouveia]

Hello to all,

I have recently been having problems with some Labview Real-Time Desktops, i have in one client, 6 Real-times desktop pc working and the 6 RT computers communicate with one normal computer by tcp/ip. The problem is normally everything works fine, but sometimes one or another computer turns off (reset) or sometimes gets strange behavior has the image i put in annex. 

Am I using the best hardware?

I create all the six computers with the Labview 2014 sp1. And the hardware that i use is the follow: 

- Motherboard Asus H81m-D or Asus H81m-C

- Core I7 3.6Ghz 4790 or 4Ghz 4790K

- SDD Kingston 120Gb V300 Sata

- Mem 2GB Ram 

- 2 intel pro1000 CT

I put in bios the Hyperthreading disable and i format the Disk in reliance mode.

There are something that i can do to have more robustness and reliability on my machines.

Because at this moment i don´t have it. 

Anyone can help me?

Overheat?  Or power supply voltage issue?  Both of those would cause your CPU to try to protect itself.  And you just know what is going to be suggested...a PXI RT chassis because of its industrial specs.

After all, Thanks a lot for your help,

About the power supply, i replace thems already and the problem remains. About the overheat i check on the bios the temperature and everything seems allright.

And sometimes i have issues, ready on the start of the computer when the temperature is cold.

Am i using a robust motherboard???

Or is my CPU (i7 3.6GHZ and 4GHZ) are not properly to the system???

In my case is not a option changes to PXI RT. 

There are more robust harwdare to make desktop in real time machines?

Thanks

Buying a PXI chassis is the obvious answer as it's guaranteed to be fully supported. For additional robustness, you could buy an industrial-spec PC with components supported by RT?

Details of the hardware supported by LabVIEW RT on Desktops is detailed here: https://www.ni.com/en/support/documentation/supplemental/08/requirements-for-desktop-pcs-as-phar-lap...

I know of nothing wrong with that particular setup, but have never personally turned a desktop PC into an RT PC, I just know it is an option.

The overheating thing I've only ever seen be a problem with not properly seated processors, or heat sinks on the processor, or clogged fans.  And I mean clogged with so much dust they spin at speeds that you can see, in the 100s of RPMs.  This was a very extreme case and we were lucky the fix was so simple.  The processor would actually underclock the CPU to keep from over heating first, so the dustier the computer was, the slower our program ran.  Sorry I can't suggest anything else that could be wrong with it.  As for replacements I've always used industrial PC that are usually rack mount.  Somthing similar in form factor to this.

Did you see this?

They've at least added this list since I last looked at this option.

Some stabs in the dark:

• Can you try LV RT 2015?
• Can you try only disabling all but one CPU core in the BIOS and checking if it still crashes? 
• Can you make sure the SATA ports in use are set to ACHI in the BIOS?
• Are there any BIOS updates available for the motherboard? If so, does updating it improve anything?
• Does disabling Turbo Boost in the BIOS change anything?
• Does disabling Deep Sleep Control in the BIOS change anything?
• Does changing Active State Power Managment (ASPM) in the BIOS change anything?

Basically, my recommendation here is to fiddle with BIOS settings to see if you can find anything that stops the system from crashing.

After all, 

Thanks for the reply,

I will see how are my settings on the bios and see if i can improve something.

Thanks,
