I've currently been struggling with my Sapphire R9 290 which I got 2 months ago. I constantly have black screening - The card simply stops working after some time on stress (Benchmarks or Heavy games like Crysis 3). I can't even go through 2 loops of Unigine Valley without it blacking out on me. I am currently running at stock speeds (947 MHz core and 1250 on memory).
I've replaced the terrible stock cooler with the Gelid Icy Vision Rev.2 (Running at 100% fan speed at all times) around a month ago and started seeing this kind of crashes. As such, I started monitoring the VRM temps while doing the valley run (Which I didn't do at all before replacing the cooler - so I don't know how hot it would have gotten then) and found out that just before crashing the Core temps were around 70C, VRM 1 was near 90-100C (depending on the occasion) and VRM 2 was sitting nicely at 60C. I remember this issue started when I first played Crysis 3 (AFTER I put on the cooler, although I was running a 1100MHZ OC then, and it stabilized on 1000MHZ).
Is the card black screening because of VRM 1 temps (which one are those? the 3 small ones or the long clutch on the right?), or is it because of driver issues? I've also updated those to 13.12 around a month ago, just when I started seeing this issue. Will try the 13.11 beta ones again.
Relevant system specs:
Intel i5 4670 CPU
Gigabyte B85M-HD3 Motherboard
Corsair CX750 PSU
