Hi folks,
Got a Sapphire HD7850 (non OC version) a couple of weeks ago. Initially I had some problems outputting signal via a DVI/VGA converter but that was taken care of by using a HDMI cable instead.
I have one remaining problem though...Often, when the monitor has gone to sleep and I'm trying to wake it up, nothing happens and a hard reset is required. If the monitor decides to wake up I sometimes get the "Display Driver has stopped working..." error message.
Since I'm not an avid gamer, I haven't done any OC yet. I'm aware of the OC potential and might try it later.
I suspect this has something to do with the Zerocore power technology AMD has implemented recently. I've closely monitored the power consumption of the computer using a watt-meter of some sorts, and it is indeed dropping 9W (from 49 to 40). So everytime I'm having these problems, the zerocore tech has kicked in. I've killed off any hibernation/sleep except for the monitor and I'd like to keep it that way.
System specs
Sapphire HD7850 @ 860, 1200
SB 2500K @ 4100
Asrock Z68 pro3-m motherboard
FSP Aurum 400W PSU (I know this is below the suggested PSU req, but this is a rather high quality PSU capable of overloading, http://www.pc-experience.de/wbb2/thread.php?threadid=31516)
The computer is 15min Furmark stable and I haven't had a single problem in the few games I'm playing. The highest power reading I've had is 170ish (not been pushing CPU and GPU at the same time though)
Any thoughts? Drivers in combination with zerocore?
