OK I am still struggling a bit with the problems with this machine

8732075

After the first problem I swapped the 1060's over, MB to riser, riser to MB. It then ran for 31 hours till this morning, then it happened again.

Most common riser problem is a "Cuda initialization problem" which starts and then postpones each task in cache after 30 seconds, resulting in all tasks showing waiting to run rather than ready to start, and eventually aborting due to too many restarts. Other common issue is simply failing to see or start up one of more GPUs.
Generally a reseat of power or signal cable or replacement of the USB 3 cable solves this.

That describes my most common issue. Once I switched to the high grade USB 3 cables, the problem seems to have been something got joggled (that happens when you carry a mining rack from one room to another). :)

Another good thought is to keep the USB cable length as short as feasible, and no more connections than necessary.
My initial build had 12"m-f cables from the card slot to the i/o panel, 3' m-m cables to the external case, and 12" m-f cables into the enclosure. So 5' cabling and two extra connections per card.
As you might imagine, those 12" m-fs went away in a hurry :).

Yes, that is the problem exactly. I have swapped the riser and all cables with a spare I had and will see how that goes.

Just in case I have ordered another different make spare, it looked slightly better built and has all 3 power connectors, molex, sata and 6-pin GPU. Which will make the power cable easier to fit, and do away with the "adaptor"

Currently I am still running with NNT, and only updating every couple of hours, so that it cannot trash more than 200 tasks ;-)

and no more connections than necessary

Something I learnt many many years ago when I was an apprentice with Post Office Telephones (now BT). Was that every connection was a potential for a fault, so always less is better.

Indeed, as I also learned at the late great Nortel.

. . So is there anyone here who is not a current or ex telephone tech? :)

Me. ;)

I am an ex-truck driver though.

Color codes??

Heh, reminds me of the resistor color code mnemonic. Haven't thought of that in years ...

Ha ha ha. First thing drummed into my head for basic electronics. That mnemonic is ingrained for sure. Both G and R rated versions.

Not sure I ever learned the G rated version. Military schools weren't known for being PC back then ...

By the time I first heard the mnemonic (both versions), i'd already memorised the code from sheer repetition of daily use.

OK a serious question.

If I was to change GPU's on one of my Linux machines, say from 750ti to 1050's would the system pick up the change or would I have to "re-install" drivers like in WIndows.

I am hoping for the former !!

Like Windows, it depends.
If the current driver supports the new card, then it will be detected and supported and that's it.
If the current driver doesn't support the new card, then you'll need to install a driver that does.
So check the current driver version, and what model hardware it's good for.

Edit-
A quick search shows your current driver (418.56) will support a GTX 1050 card.
I don't know how things are with Linux initialising new hardware, but with Windows I suspend processing in the BOINC Manager, then shutdown the system, install the new hardware & re-boot. Once the system has found the new hardware, installed it & everything is good, then I re-enable processing.

It should just work. You have the 418 drivers which supports both cards.

Thanks, I may just find out this week. ;-)

B-B-R-O-Y-G-B-V-G-W lol :) I only know the R version, never heard a G version.
