Will run a few tests tonight while logging with GPU-z and see if any patterns emerge.
I have a hopeful feeling that it may only be the HDMI port that is the problem. I hope the same tests under DVI will yield no issues.
I am hesitant to RMA because I have heard sapphire is a nightmare to deal with, and my 280x came used (though only 1 month old)
Will give you feedback. Any chance the factory OC is not the most stable?
UPDATE: I ran Unigine Heaven for a while on Ultra settings (extre tes, 8x AA) and had no issues, over DVI. I hit 70*C with no issues. Will try Witcher 2 over DVI (and see if no issues arise) and will also try Heaven over HDMI.
I am hopeful/thankful it is only the HDMI port. Is this a bad sign though of bad things to come, or can I just write it off as a bad port? I can live without HDMI.
UPDATE 2 --> certainly is not the HDMI port. I am screwed.
I will upload my GPU-Z in case anyone can help me before I RMA. The graphics card does not just fail always -- for example, I played 5 hours of company of heroes 2 with no problem. And I ran the Heaven benchmark until 70*C with no issues. But sometimes it just fails.
Anyway, attached is the spreadsheet. I crapped out somewhere near the end, I believe at exactly 20:29:05http://m.uploadedit.com/b041/1413852359810.txt
Prior to that, I am running Heaven benchmark (see 99% utilization at 20:20:00 and around there. I start testing Witcher 2 at around 20:26:06
So there are 3 minutes in which I am playing without issues, and then BAM, red vertical lines...
Any help is greatly appreciated. Otherwise...RMA Edited by Rykoshet - 10/20/14 at 5:47pm
