    http://www.newegg.com/Product/Produc...82E16814125414 I did notice some flickering with my screen as well, well more like 1 flick every so often. Also ended up getting a blue screen when playing kingdoms of amalur (driver_irql_not_less_or_equal) though people said when I looked it up that had to do with either ram or hdd.

    Hang on, doing some tests after reading that recent drivers have limited people OCs compared to older ones. My current card can only do 990/1500 on stock voltages in Far Cry 3 (even though it was 1035 stable in unigine). Going to test 12.8 drivers along with my other card.

    EDIT:: Dunno what the guy was smoking when he said he lost 75MHz off the OC going from .8 to .10, exactly same clocks as .11 for me. Although he was using a 7970 but shouldn't make too much off a difference. Same thread had a poor guy who apparently wasn't even stable at 900/1300 on a 7950 though, never heard if it stopping that low before.

    Upgrading my drivers for my card did kill my ability to overclock it via MSI Afterburner. Any adjustment at all and the screen starts going haywire. I also get the one screen flicker every so often.

    Do you have any other overclocks beyond GPU? If restarting doesn't help then you need to test HDD/CPU/RAM (HD Tune or CrystalDisk Info/Mark for S.M.A.R.T data readout and read/write tests, Prime95 small FFT for CPU and blend for CPU+RAM, memtest86 for RAM)

    Was pretty normal when I checked this morning before heading to work. I did OC the CPU, under IntelBurn it was stable though.

    Thought I would hop onto this thread instead of putting a new one out for a quick OC question:

    Is there any significant danger of setting your VCore low when OC'ing? What I've read in a few places seems to say "pick a clock speed you want to acheive and then adjust your vcore down until you find the lowest stable value" but I don't know if there are any extra 'risks' with having a low VCore setting. I'm easily managing a light OC on my i2500k at 4 GHz at 1.240V VCore and it's good an stable under both Prime95 and Linpack (though I haven't run it for more than 3 hours) but I don't want to undervolt the CPU and risk damaging its lifespan (if there is such a thang).

    If you go a bit low then playing games/running Prime95 will cause them to crash (or BSOD), if you go far too low then your PC will fail to boot (at which point you have to reset CMOS, either with the button or removing the battery). You shouldn't damage a CPU by feeding it too few volts
