    Powercolor HD7970 Core Voltage Issues

    Driver crashes happen at any clock speed and any voltage purely for 7k series cards with the streaming software XSplit, but nobody is entirely sure as to the why. The cards are 100% stable otherwise and inclusion of XSplit causes some kind of conflict with something only in 7k series cards which...

    Powercolor HD7970 Core Voltage Issues

    Do I honestly have to underclock by 100mhz core and memory from default, overvolt to 1250mV, run the same tests with the same crashes and then post identical logs with identical crashes under identical circumstances? Okay. That what a rehetorical question, but I'll do it anyway then I can...

    6970 CFX to 7970 CFX or GTX 680 SLI or GTX 670 SLI?

    Offhand: On ultra at 1920x1200 (The dying breed of 16:10) my single 7970 can peak at using 2.3GB of the 3GB memory available on the card just in single player Battlefield 3, I haven't seen any indication of what memory usage multiplayer could have but can naturally assume just as much or more...

    Powercolor HD7970 Core Voltage Issues

    It's a standard 925 core/1375 mem card. I've tested it from a mild underclock, to stock, to my current overclock. I'm using the most current 12.7 beta, this problem has also happened with 12.4 > 12.6. It is "supposedly" an interaction between XSplit and AMD's ZeroCore tech on the 7xxx series...

    Powercolor HD7970 Core Voltage Issues

    GPU Tweak doesn't seem to be capturing the VDroop at all, but here's the readout from the latest test: http://pastebin.com/iQfHZC3w Search for "*** DRIVER CRASH ***" for the point when the driver crash happens right at the bottom. Until then it looks stable. Any fan discrepancies can be...

    Powercolor HD7970 Core Voltage Issues

    Power supply is 850w. Using a Socket 2011 i7 3930k OC'd @ 4.4ghz, 24GB of Kingston HyperX @ 1600 CL-9 in 6x8GB setup. Mobo is an ASROCK x79 Extreme7. Haven't used a multimeter to measure the actual voltages. I didn't know about or what Vdroop was, so I did some research and it seems in...

    Powercolor HD7970 Core Voltage Issues

    I've disabled ULPS via the registry and I'm using MSI Afterburner to set new voltages and overclock my 7970. I'm also using dual monitors. Using HWiNFO64 my voltage readings are consistently about 10mV below what I have in Afterburner, but that's not my problem. My problem is the damn card...
