my atifacting issues were non existant last night in BF3 so thats a plus.

Just wondering, does anyone else's card freeze the display when you OC the core too high for the voltage you're using? I had started thinking my card was a relatively bad one because whenever I went above 1050MHz the display would freeze. Not a hard lock, because the audio would continue and programs would keep running, but I would still have to manually restart the machine. It seemed weird because I expected the driver to just crash and recover, like my older cards did. Anyway, I think my card is actually pretty good because Afterburner's default voltage is 0.993V, but the card is not even close to cool, and it sure heats up fast when I up the memory speed. I'm guessing it'll get better when the season changes (my computer room is pretty terrible... stuffy in the summer, chilly in the winter).
My MSI 7950 came at stock volt of .993 in afterburner
I have not tried overvolting it yet but I am getting stable at 990 mhz oc. Have not touched the memory yet.
I have an ASIC of 92
Keep in mind that most setups you are compared against are K chips 4.5GHz+, driver differences and memory play a role too.
I just started bitcoin . At stock clocks and 1.012v, it doesn't exceed 68C/58% fan setting (fan set to auto control). I get up to 500 MH's. I never tried it on the 5770 so I can't compare scores. I've been hearing about BTC for a while now so I thought why not.
yes I have this issue
No, that's what's supposed to happen with HD7800/7900 series. When the GPU isn't getting enough voltage, you get a hard screen lock. That means 100% a failed overclock. Sometimes the driver recovery is able to kick in and you'll see a bubble on the taskbar telling you Driver Has Recovered/Failed or something similar. That's just AMD's "Fail Safe" overclocking reboot. But it can definitely hard lock. Anything related to sudden driver crashing that wasn't there at stock speeds, hard locks, black screens, BSOD is failed overclocking. :thumbsup:

Decided to stick to 1200/1800, Figured out my cpu issue. CCC and my anti virus was definitely holding me back. Theres my system's P score. I'm quite impressed with hitting 10k on the gpu. Definitely might make someone think twice about buying a 680 for $200 more.
if you want to bitcoin do what I do. set the voltage at .82 yeah that is right .82 v then set the core clock at 750mhz. next set the memory voltage at 1.5 v and set the memory clock at 625 set the fan at 60%. what happens is the hash drops to 360-375 but you drop more then 100 watts of power! the machine runs cool at 65c to 69c it is also much quieter. also you can use the computer for many other tasksIs anybody testing for lowest possible voltages for bitcoin mining? I've managed to get 1.0v at 1100/625 and it's stable for mining at 99% gpu usage, but using the desktop while mining might lead to crashes. It seems to run fine at 1.0v if I leave it alone. I'm stable at about 1.01v though (mining, not gaming) at 1100/625 with any desktop usage while mining. That's pretty impressive.
Voltage needed seems to be very low for me at or below 1100, but it increases rapidly after 1100. I have no need for more than 1100 so I'm good.
Changing TdrLevel to 3 (i.e. turning it back on, which is its default value) and restarting fixed the problem for me. It didn't really help in a benchmark like Heaven which applies constant 100% stress to the core because it would immediately re-crash after recovering , so I was unable to kill the process in the brief times I had control of the desktop, but for ordinary games it's back to working as normal.
Nice. I think you could separate yourself from the pack even further by turning the CPU up a notch or two and trying one at 1225 but even as it is, you got great numbers. What FPS do you get during PT, I rarely/barely break 19FPS with my i5-2400
Totally agree about the value. I'm stable at 1100/1575 on 1049v and while that clock doesn't quite cut it against OC'ed ref 7970's, it's certainly cooler and quieter than those. I'm BTC mining when I'm away, 570 MH/s at 72C max and the default fan setting setting stays below 60%. My 2 extra fans keep the vram below 80C at all times.
Despite the CPU bottleneck here and there, I'm happy with the way it's doing so far and guys with K chips can really let the card stretch it's legs. With some wafer lottery luck and good cooling, this card can run 1.2 GHz 24/7 and that's the final nail in the value argument coffin.

Benchmarks to come soon. Oc'd and stock!
Hey Sze5003, i have a picture of the card. It measures almost exactly 11". Its on a 7970 PCB so thats pretty much what you'll see for a 7970 as well. Some models depending on the air cooler from other manufacturers will have a variance between 11 and 11.75.
Seems my case will fit up to 11 and 3/8."
Few pages ago, I was in a similar dilemma.
Same here:
If your case is anything like mine, buy additional fans if you plan to OC past 1000 on the core.
Make sure you get one of the aftermarket 7970s. Reference models are loud and have poor cooling. With a small case it will be very hot.
I wouldn't get a reference 7970 when after-market 7950s such as the MSI TF3 are going for $320-330. If you want a quiet card for $380-400 and don't want to overclock, GTX670 Windforce 3x or similar are great options too. No need to limit yourself to AMD. However, a reference 7970 is neither quiet nor a great overclocker on air.
