I have a Sapphire HD 7950 dual-X with boost. This one in particular - http://www.newegg.com/Product/Product.aspx?Item=N82E16814202006
I have used AMD Overdrive and overclocked the core clock to 1155 mhz, and the memory clock to 1450 mhz. In order for this to run stable, I adjusted the power control slider to +10%.
I have overclocked processors before in the past, but never graphics cards. I just want to know that everything is fine and that my GPU is not getting too much voltage or anything, some assurance that it will be fine as it is.
I ran Furmark for 15 mins as my stress test and seemed to have no problems at all, I did the standard burn-in test at 1080p with 2xMSAA. I used both HW Monitor and GPU-Z while stress testing with Furmark.
Here are all of my results:
GPU-Z readings while stress testing -
12V: 11.94V
VDDC: 1.061V
MVDDC: 1.602V
VDDC Current: 103.3A
VDDC Current in: 11.3A
HWMonitor readings while stress testing -
Voltage: 1.125
Min Voltage: 0.950
Max Voltage: 1.250
GPU-Z readings while idle -
12V: 12.09
VDDC: 0.803V
MVDDC:1.602V
VDDC Current: 4.3A
VDDC Current in: 0.3A
HWMonitor readings while idle-
Voltage: 0.950
Min voltage: 0.950
Max voltage: 1.250
With this setting my idle temp is about 35c average, and max temp while stress testing with Furmark for 15 mins was 73c.
I apologize for all of the numbers, I don't really know what they all mean, and it would seem that the HWmonitor readings don't relate much to the GPU-Z readings.
Looking at all of these voltages and amps and stuff, does everything seem fine? I noticed no graphical anomalies or anything of the sort while stress testing. I also tested a few games for about 20 mins each and they seemed to run great.
Any thoughts or input is greatly appreciated! Thanks
*EDIT* Novuake, what did you use to OC your card? I used AMD overdrive and the MAX slider settings were 1200MHZ core clock and 1575MHZ memory clock. I attempted these settings and put the power control slider to max (+20%). It seemed to work fine in the Furmark and Valley Benchmark, but when I tried to play Crysis 3 like that it would freeze up after about 15 seconds of playing, then my graphics driver would crash :/
