So far I'm left with these models to choose form.

ASUS Radeon HD 7850 860MHZ
Visiontek Radeon HD 7850 860MHZ
Gigabyte Radeon HD 7850 OC 975MHZ
Kinda shying away from the Visontek.

I would normally not recomend the Asus DCII models, but for the 7850 line, they are doing quite well! Not only my card, but others as well. And Asus's warrenty is quite decent too!

Gigabyte would be my next choice, but as you can see in the list from page 2, not many here have chosen that manufacturer for this card.

I heard the Gigabyte had high pitch noise issues for this series.

Had to move power slider to 50% to get stable OC past factory. Now doing 1000/1300 fine I will go 1050/1450 tomorrow.

Thanks for the help guys.

Recently bought a Gigabyte 7870 and I haven't noticed any high pitch noise issue. I can barely hear the card at all, 20% fan speed at idle and max 45% at load.
Only bad thing about it is that it doesn't overclock as well as Sapphire cards for example, was only able to achieve 1220 core clock and 1450 memory on 1.3mv. Stock voltages are stable at 1150 core and 1450 memory.

Maybe its just my card, got a 76,3% in the ASIC test.

Hey guys,

Need some advice / tips here.

I am able to get 1280 / 1450 on my XFX DD BE 7870 for a respectable 3DM11 score of 7890 (I would like to hit 8000); disabling Windows Aero I get 7908 smile.gif Learn something new everyday. For the most part I am seeing a consistent voltage of 1.274 but I am seeing voltage spikes of 1.325 and even a single spike of 1.60 thinking.gif .

I can push this card further but this voltage spike is a little disturbing. It occurs during either Graphics Test 1 or 2 in 3DM11.

Max temps at 60c; GPU usage 99%.

Also, what are you guys using to overclock memory?

I attempted 1285 / 1450 same voltage (1.274). As you can see the 1.6 voltage spike is now more pronounced occurring in graphics test 2 for 75% of the duration and also a spike in graphics test 3. Everything else is normal, no artifacts, no insane temps, no crashes or hard-locks.

Should I disregard this spike? Am I just not meant to exceed 1250 core clock?

I'm using GPU-Tweak from Asus as AB doesn't fully support my card's voltage regulator. Secondly, I use GPU-Z to monitor my max voltage when benchmarking.. no spikes found.

Thirdly, you are using an outdated AB beta (I think). The newest retail version just launched 2 days ago. Might want to give that a try.

Thanks,

Downloaded latest MSI AB, still showed similar spikes so I clocked the core up to 1300 and the spike dropped. ???

I used GPU-Z to monitor the card and it showed a spike of 1.998 V!!!!!!

WHISKEY TANGO FOXTROT?!!? I DON'T KNOW WHAT THE HELL I AM DOING! lol.

I do find it hilarious that 3DM11 benched me at 7970 though!

Instead of saying "your score is comparable to similar systems" it should say "Your overclocked beast pwns similar systems."

Hmm.. you might want to contact XFX about those spikes then. Or possibly a full reinstall of the 12.3 CCC drivers could help?

And LOL at your last comment thumb.gif
