VIDEO IS HERE: youtu.be/yBfQKwNqEyU For some odd reason, my link didn't go through ...
I recently got two 780 GTX Classifieds (Got them fresh a week ago
). After having to replace my first PSU, performance was PHENOMINAL except that sometimes I get lines going across one of my screens.
Since fresh installation to other various forms of trouble shooting, when ever SLI mode is enabled/disabled, one of the screens will display vertical dots/lines that travel across the screen towards the left horizontally. ( youtu.be/yBfQKwNqEyU)
The monitors are hooked up to the TOP (main) GPU while in SLI mode, the current display that is showing the lines is plugged into the HDMI port, but the DVI and DVI-D has also exhibited this issue... The monitor it happens on is not consistant!
A monitor is hooked up to the regular DVI with a DVI to VGA adaptor, as that monitors DVI port has EDID issues. I use the DVI-D, DVI and HDMI ports. I have tried three different SLI adaptors to no avail to see if that was causing this issue.
My screens also flicker once in a while, as if auto-adjusting, not sure if that matters either. I also have the fan noise issue with the resonating fins... Saw that thread on how to 'fix' it.
* I did have to replace my PSU initially, had a 1k watt PSU, but it was bronze rated and would not play nice when the CPU was overclocked, everything at stock had no issues however, recently upgraded to a 1.3k watt PSU (listed below in specs)
Gaming temps never go beyond 70c. The top card scores a 70 FPS average at 1080p with 8x AA, bottom card gets the same score. Heaven and Valley work well, as well as Crysis 2, FFXIV and GTA IV with graphics mods.
Clean driver installation, driver wiper, CCleaner, un-installation of EVGA precision and afterburner (I only use one or the other), the works and no issue. Issue is apparent even when the CPU is running stock. These cards have not been overclocked.
