Seems that it ships with a 'choice of Windows 10 Pro or Linux operating systems', but I don't see which distro.
HP Workstations officially support RHEL and SLES, looking at the Datasheet for this little guy confirms it;

How are you able to "see" the single bit errors? I had an ECC machine but I couldn't find any indication that ECC was working or that any bit errors happened. Reading this I thought the best I could do is to believe that workstation with ECC modules and Xeon will have functioning ECC: "Unfortunately, we have found that there is no consistent, conclusive way to determine if ECC RAM is working properly. ...We've actual…
The BIOS has to correct them, you get what is essentially a machine check, the BIOS fixes the error, does the writeback, and in my case logs the fix on the system management (SMB) bus and that shows up in the IPMI system event log[1]. Not sure who the BIOS would tell if there wasn't some sort of BMC chip to hear about it, it might keep an internal log. I'm surprised the board/bios manufacturer couldn't answer the que…
That's interesting. Is it possible to use IPMI and log BMC events on a regular workstation from Dell or Lenovo, perhaps via some expansion card? Or is this only a server-grade feature?

Linux has drivers that receive ECC notifications from the hardware and the edac-util command should display them. You can cause bit errors with a hair dryer and see if Linux recognizes them: http://bluesmoke.sourceforge.net/heat_gun.html
Thanks a lot! I'll probably try both after I get my machine working again.

Fair enough. My main ergonomic requirement for a workstation is zero noise at rest, and reasonable otherwise. I'm interested in seeing what I can get in form factor though.
What I did (but I'll admit this is not an option in many cases) is to move my workstation into a rack in the basement, with 20m DisplayPort cables connecting the monitors and a 20m usb3 extender cable hooking up a usb hub on the desk for keyboard, mouse, usb storage etc. Let the computer be loud there - noise has become a non-issue when selecting parts. It has a gtx1070 GPU which gets quite noisy under load (gpgpu pr…
A similar strategy I am considering. Get a fanless NUC case from Akasa [http://www.akasa.com.tw] and remote desktop to the "real" computer in the basement.

#235Does it sound like a jet engine? I was disappointed how noisy even the small Lenovo Thinkcentre desktops were.
Really?
I've got a ThinkCenter M73 right next to me running a hypervisor for several Windows VM's. Even under load I don't hear a peep out of the thing.

They're also logged by some portable mechanism on normal x86 boards, viewable at least using the "mcelog" tool under Linux, and probably logged by the kernel in the normal kernel event log. I think the mce log is supposed to persist over reboots so you could see the multibit error afterwards if you got a machine check induced reboot.

>> It would compete with the IMac then, and with their notebooks too. Companies that try to avoid competing with themselves often fail quickly and spectacularly (after this approach appearing to work well for an extended time).
Apple historically hasn't had a problem competing with itself - iPod mini - iPod nano - iPhone, each of these completely destroyed an existing product or product line.
Apple probably is an exception rather than a rule here; their products are so overpriced that any new product success easily makes up for previous products losses.
It might be a bit different for "normal" companies though.
