Any chance of testing it using the Xtreme preset?

[Gaul]

6850 @ 1075/1200

[Rattle]

1000/1150

is that on stock volts?

[ScottyPimpin]

1000/1150

is that on stock volts?

I'm curious about that also. Atm only the asus 6870 can increase volts with the asus utility. I get my gigabyte 6870 in the mail friday so i'll be posting mine this weekend.

Interesting, your 6870 is about 2.5k GPU score behind my 5850 at the same clocks (Well 1300mhz memory).

Kit guru website reviewed the 6850 Black Edition card:

They got it over 1Ghz on GPU.Pretty neat stuff.

Sapphire 6850@850/1200


Tried MSI ab/rivatuner but above 850 I get Lockups/freezes.. waiting for TriXX to come avaible.

Also a option to disable powerplay with CFX

hei ? on 6870 CF does't had that option

anyway i wonder does 6850 cf can touch def 6870 CF ? gpu score = 28.8 K

[Bullu$]

Just wait for some oc-tools,then I can reach 1GHz

nice, post here if done....

btw single score GPU Score 6850 on vantage ??
I'm sure to touch 15.8K need 6850 @ 1050/1100 to catch 6870 def score = 15.8

Gaul,

How are speeds over 1Ghz? My first 6870 will do 1060 but my 2nd hates anything over 1030.

Arctic cooling needs to hurry up and release a cooler or adapter plate , Any ETA on EK Waterblocks?

i can't max only 1000 on cat, the question is how 1060 ? with software ?

I just got my 6870 yesterday (Sapphire), and to be honest I'm not really used to OC'ing VC's...

I can say that I'm really impressed with the performance and video quality though!
My 3D06 score was right on par with the 4870/4850 CF settup I was running (before oc'ing then new card).

I used CCC to overclock it and ended up with 945 core and 1135 Mem (auto OC).
I get the feeling the card actually has alot more in it because the fan speed never really even kicked up, and I'm sure CCC doesn't push the card too far.

Could someone reccommend a good bench to really push the card, so I can stress test with confidence?

Also, since TriXX isn't available yet to allow voltage adjustment, what would be the best software to let me push past 1000 core (Afterburner)?

Thanks... Dave

do manual oc, not auto i'm sure easy touch 1 GH with CCC

Here is ASUS 6850 DirectCU at 1000 core. I am just testing core oc at the moment so memory is not oced much.

[Gaul]

@ ^ = nice, like i was told 6850@1000/1100 will had same score as 6870 def

Which version of smartdoctor do u use? can u upload it?

[Funky]

I have installed the one that came on the CD, it is seriously buggy at the moment. Has its own mind about what voltages it wants to apply. I am not even sure its working properly.
I will upload it when I get time. Asus really needs to fix it.

[djmattm]

Those are really nice results, how about temps?

this question ask to ???

[CrazyNutz]

Gaul: I'm interested to know how do the gtx460, hd6850, and hd6870 compare at the same clock speeds. can you test?

as u wish, i'll play on 900/1100

460 @ 900/1100 and 6870 @ 900/1100
damn, i don't have 6850


460 @ 900/1100

OMG, that 100MHz on core are with vmods or only with MSI AB?

AB only........its easy, def gpu is 900 mhz
