Hi all, long time lurker first time poster. I have a very disruptive and rather critical issue and I'm hoping someone might be able to offer some helpful ideas.
I have a computer which has a requirement to run a large number of monitors for work purposes. For this I am using intel onboard and 3 nvidia geforce series cards. I was previously using two nvidia cards, however I recently switched things around and added another card and since then the nvidia driver has been completely unstable. After some time of use (varies from seconds to hours) the displays attached to one of the cards (which card it is varies) go blank, and the nvidia driver gets reloaded. If this happens enough times windows crashes with a tdi error.
System details:
Asus z97-a
Win7 x64
Various nvidia drivers tried (most recent way back to when the 950 was initially supported)
card configurations attempted: gtx950 + gt730 + gt730, gtx950 + gtx660 + gt730, gtx950 + gtx450TI+gt730
Things I have tried:
New PSU
new video cards (see above)
many many many nvidia driver versions
verifying system ram timings in bios
ensuring nothing is overclocked
underclocking video cards using msi afterburner
Playing with windows tdr settings (If I disable tdr the computer doesn't bluescreen, but I will permanently lose monitors until reboot when the issue occurs)
disabling all power saving settings in windows and nvidia control panel
As far as I can recall things were working fine up until I put the gtx950 in. So it would seem that it doesn't play nice with older cards, but I don't have any idea why that would be the case. I do need the 950 in there since I sometimes do game on this computer (on a single monitor). And I don't suspect the 950 of being faulty because I can play games on it full screen (1 monitor) and it never crashes.
Any help or thoughts about what else to try would be GREATLY appreciated, before I throw in the towel and chalk this up to 900 series and 600 / 700 series incompatibility. Which would be lame.
