Got my card today but it's the wrong one... They sent me this MSI
instead! From what I've read this card is better than the Sapphire one I ordered so I will definitely be keeping it. I am not sure though if this is the boost or the regular one but it's stock core clock is 960mhz which doesn't match either so I'm going to assume it's the boost.
So far over clocking wise I've been running Unigine Valley and doing 25 incremental increases on core and then memory. I run Valley stable at stock voltage (1.125v), 1175mhz core, and 1500mhz memory. My best score was around 1968. However, if I bump the voltage up to 1.175v I can run 1200mhz core and 1500mhz memory and get a score of around 1979. Sadly though I tried running 3dMark (the new 2013 version) and it crashed on the first test
The 1175 over clock did run stable though.
I am uneasy about playing with the voltage to much because I don't want to kill my card. If you guys have any experience with this I would really appreciate any advice! With both those over clocks the card tends to float around 69 - 70 degrees celsius and the VRMs are around 75, but my A/C isn't working so the results are a little skewed since it's about 10 degrees fahrenheit higher than normal. Tomorrow when my A/C is fixed I am going to play around a little more and see if anything changes. I only tried one game to test the over clock and it was completely stable, not sure about the temps I forgot to look.
Even though I received the wrong card I am overly satisfied with my purchase. The performance increase is way more than I would have thought and after selling my 7850 I only spent around $125. This may be a stupid idea but I am seriously considering buying another for crossfire... I'm going to try and resist the urge until AMD gets these new drivers perfected but the thought of that much power has me drooling
