My system is not overclocked. Everything is stock.
Intel i5 3570K
ASUS P8Z77-V PRO
2x GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X
Kingston Hyper-X Blu 16GB
Antec 1000W PSU
I also have an Antec DF-85 case. So air flow is not a problem. The card does not exceed 75c ever and as the rest of this thread suggest it happens when idle or doing 2D tasks such as browsing.
I have sinced RMAed one of the cards because I thought I isolated it to one card and was recommended by Gigabyte. This was 3 days ago. The day after I started noticing a flicker on the other card by itself in my system.
I found a post on another forum that recommended downgrading drivers to the drivers that came on the CD with the card which is 13.10. Since fully uninstalling the old drivers and reverting to these drivers I have only noticed a flicker maybe once.
Based on that this leads me to believe this is purely driver or bios related. Not to mention other vendors ASUS, Sapphire have all fixed the issue with a BIOS update.
If I don’t get a resolution to this soon AMD will be losing a long term customer of almost 15 years.
