First, some info:

Memory Size - 4096 MB

Memory Type - GDDR5

Core Clock - 1250 MHz

Windows Version - Windows 10 (64 bit)

System Memory - 16 GB

CPU Type - AMD Phenom(tm) II X4 840 Processor



HP 23bw (1920x1080@60Hz) connected via HDMI

VA2251M-LED [Model #: VS14589] (1920x1080@60Hz) connected via DVI


Motherboard - BIOSTAR Group A770E3

PSU - Corsair 850w Modular PSU


Now, the problem:


I received this card as a gift in September, and right out of the box I had an issue with the image beginning to flicker after an hour or so of use.  The flickers in question involved reverse-color images, the image bouncing up and down, very similar to wiggling a loose DVI cable at one end.  It did not involve any loss of signal or 'flashing to black.'  I found at first that disconnecting and reconnecting the DVI display would 'reset' the problem, allowing me to use the PC flicker-free for about another hour or so, until I had to do it again.  Going into Device Manager to disable the driver, and then re-enabling it would also reset the problem.  Additionally, disabling the driver via Device Manager would prevent the problem from occurring until I re-enabled it.


The problem isn't related to heat, as the flickering seems to start based mostly on time, if I leave my computer alone on the desktop with no programs running, but the drivers for the card are enabled, I will always return to a flickering screen.  It seems to be somewhat related to load - if it has just started to flicker and hasn't 'gotten bad' yet, it will usually happen in loading screens or when games are loading new assets before it becomes a constant thing.


I described this problem to Sapphire, and they postulated it was likely a hardware issue, and told me to ask a third party for an RMA.  I sent the third party my card for repair/replacement, and while it was out for repair I had an old HD 6000 series card installed, and did not have any of these problems occur at all.  About a week later I received a brand new card in the mail from them.  However, the day I plugged in this brand new card into my machine, mere hours after finishing a clean install of the drivers, the flickering had returned.


This problem has occurred on every driver version that has been released since September 2016, as I have been updating frantically and obsessively, hoping each new version would provide some kind of magical fix.  That still hasn't happened yet, though, and a complete replacement of the hardware has also done nothing for me, so I'm hoping I could perhaps get some insight here on how I can solve this issue for good.
