Hi there
A machine I use as an octane slave with 4x 1080Ti's is repeatedly giving me the following error in the slave console.
Everything works fine until it's been rendering, sometimes for a few frames, sometimes for a while. Then I get a 702 and the console freezes.
The scene type and complexity, memory usage etc do not seem to have any effect on the crash. It can be a simple scene or very complex and the issue is the same.
The error is always a 702, but the description is sometimes different. It can be; "failed to copy memory from device" "failed to allocate/deallocate memory" "could not get memory info"
At this point it can also freeze the master (presumably it's waiting for the slave and getting nothing)
Sometimes the slave machine OS becomes unresponsive and throws a BSOD DPC_watchdog violation.
I've tried to isolate the cards and render using each of them separately, I cant get any single card to fail, but any combination of cards will fail.
I have re seated every card, tried again to narrow it down to a failing card or cards and failed.
Running tests like Furmark and vram tests show no errors on the cards, and during stress tests none of the cards have exceeded a heat limit or crashed. Theyre all hybrid watercooled and the temps never go above 50 degrees.
The driver the cards are using is a stable Nvidia driver that I use on another octane machine with no issues.
Bios, firmware, HDD on the slave machine are all latest updates.
Aside from cinema4d and the slave install for octane there's nothing else on the machine except the OS which is Windows 10 Pro.
Machine specs;
X99 E -WS USB 3.1 mobo
4x 1080ti EVGA Hybrid
Samsung 850 Evo M.2 500gb
64GB corsair DDR4 ram
Intel i7 6850k
Any help greatly appreciated.
