Ever since I went from Windows 8.1 x64 to Windows 10 x64 (fresh install) a month or two ago, I've been having an issue with the displays losing signals randomly regardless of what I'm doing at the time. Looking in the event viewer, I can see 10 Event ID 4101 warnings saying:
"Display driver nvlddmkm stopped responding and has successfully recovered"
Contrary to what the message says, the displays never get signal back (even using WIN+CTRL+SHIFT+B) and the only solution is to power-cycle the PC. This issue seems to pop up randomly both with a mostly-idle system (browsing the Internet, chatting in Slack) and with a more heavily utilized one (Diablo 3, 7 Days to Die). Sometimes there are no issues for days and sometimes I get this once or twice a day. This is not a BSOD, however, as I could still hear sound coming from a youtube video playing in Chrome and was even able to continue conversation with someone in a Slack voice call for a few more seconds before that stopped working as well. Specs:
CPU: Intel Core i7-4930K
Motherboard: ASUS Rampage IV Black Edition (latest BIOS)
GPU: 2x EVGA 980Ti Hybrid (in SLI)
PSU: 1000W 80Plus
I realize this is a fairly common issue that has been around since the beginning of time, so I did check most of the usual suspects:
- Set TdrDelay REG_QWORD to 8 (also tried 20)
- Set Power management mode to "Prefer maximum performance" in the NVidia Control Panel
- Set Computer power plan to "High performance" making sure Link State Power Management is Off
- Currently using Geforce 430.86 drivers (latest as of this post), but also tried 416.94 drivers with the same results, no Geforce Experience installed. Using DDU 22.214.171.124 to uninstall drivers with network disconnected until new drivers are installed.
- Cooling is fine, the GPUs were running 30C-40C on both cards when I've seen the issue occur
The GPUs are both factory-overclocked with the same clocks, but one seems to be a newer revision - they are both running same BIOS version, however. The primary card is typically running at higher clocks than the secondary card when just browsing the Internet and such, which makes sense, but maybe something weird going on with the different power states?
I did get EVGA Precision XOC and now I'm wondering if I should lower the clocks somewhat from the factory-overclocked settings or if a better solution would be to give it some more power? What would be the best way of doing this? I see the GPU/Mem Clock Offset sliders, there is a Power Target slider (100% at the moment) and a separate voltage slider to stabilize overclocks. I was thinking maybe I should boost the voltage slider a little bit to see if it helps - by how much (its in mV)?
Thank you for any help, this has been driving me crazy
