and the default profile only lets the fan reach 50% max on full load!!
Sorry, I didn't want to answer since I don't have my sig rig with me right now. I just set mine to 1%-1C and called it a day. The thing is I can't remember exactly how you do it. It's been several months now.

Yeah, it was only $40 for me. At the egg, it was $55. Not cool man. Not cool.
I know you have an XFX, I was just thinking maybe the model besides ZNFC has more than 2pin. Again, if you just max out the fan in PSU it's not gonna be noticeable.

I think I paid $35 with free shipping. Of course, that free shipping came at the very end of the very last day allowed. Still free though.

50% max fan speed is reached with fan profile set to auto
I don't think it should be that hot at stock. How's airflow in the case? Got a spare fan that you can connect to PSU? You can try taking cover off, blow spare fan at GPU and see what temps you get.

My fan speed is 40% until about 65-70 and then it starts picking up.

I own a CFX configuration of 2 x R6850OC. I´m having BSOD problems. I know I can solve them by underclocking the memory clock to 900 MHz, but i´m unable to do so with CCC. I can´t underclock less than 1000 MHz, is there a way to modify this so I will be able to reach the 900 MHz safe clocks?

NOTE: Using MSI AfterBurner isn´t an option!!!, the idea is modify CCC or some registry entry to modify the clocks.

When OCing the 6870 past 975MHz core, my screen will eventually split in half vertically, sending the right half to the left side and the left half to the right side. Typically when a card is overheating I just see graphical corruption, artifacts, and a rapidly approaching system freeze. Is the above symptom an overheating (IIRC it happens at <80C which the card should be able to handle) or a low voltage issue?

Im back...

So I formatted installed al the latest drivers and caps.

Same problems with Black Ops....now even have the false FPS ( Running 90 fps but feels like 45 ) on 1 single card.

Also getting lines running down sreen.

Crossfire is just not for me.

Selling my cards and getting a GTX 570.

Cheers guys!

yes it is suprising for it to get that hot on stock clocks!!

i have two 120mm fans (1 as intake other exhaust at back) and i 80mm top intake
i tried an 80mm exhaust too but i got better results with intake config.
also i have tried a 120mm intake on the side panel to blow cold air on the gpu but it had next to no impact on temps.

Will it be ok to use intel stock TIM on 6850?

@a pet rock
thnx dude

What about Trixx? Why isn't Afterburner allowed? From everything I've heard overdrive just isn't that good, so I never messed with it. Also, I'm curious how you decided underclocking memory would solve the problem. Is it the specific BSOD code? I don't know enough to know when underclocking would help.

It just sounds like your card has hit the wall. I think increasing the voltage would be the only thing that can help, if it does.

Anyone overclocking a 6870? Looking for max core clock and max mem clock on stock voltages?
Thanks

How do you like a 6950 like this?



A nice heat exhaust turbine videocard never seen before (110mm fan)
