tested with 1120/1140 but get lower score

Where is your score? U also have a 6850 or 5850?

2x 6870

here it goes:

How's this for Hawx 2?


GPU @ 900/1450




A heaven extreme run as well at same clocks as above:



(3fps minimum... could not be arsed to run it again to bring that up)

[Kensek]

2 HD6970s at 950/1450 with i7 950 at 4.5GHz in 3DMark11 P Setting.





Here is Vantage -




And here is 3DMArk06 used Afterburner to OC the first card past AMD's CCC Overclock Profile to 987/1500.

However Afterburner can't OC past the CCC Overdirve limits on the second card.

[Oztopher]

Impressive. Although you might want to try the 10.12a RC3 drivers. Even though they have a lower driver package number they apparently 'officially' support the 6900 series. RC2 (and above) brought improvements to 3dmark11 for me, maybe some other games etc. i haven't really tried.

Also, a link to a GPU-Z test build that supports 6900 series, works for me

@ ^ = 1408 shaders ?

[Oztopher]

Yup, 6970 has 1536sp and 6950 1408sp.

Unsupported gpuz version shows same shaders as 5870 and 5850 (1600sp and 1440sp).

[T_M]

vrzone vGPU mod is confirmed working on 6970, will start on vMEM and vDDCI

[T_M]

All 3 mods are confirmed. Removal of the resistors was easy using tweezers and sideways force (no solder iron)

GPU 1.300V idle / 1.32V load - ambient 24C

Link?
All I could find was some soldiering a pot mod for voltage...nothing about removing any resistors...

[flopper]

sweet.
Look forward to more

[Pyr0]

nice result T_M

near the botton it says:

MVDD and MVDDC are supplied by individual power regulators. You will need to remove the 0402 resistor highlighted above. Tune a 100 kOhm potentiometer to 63 kOhm, and solder it across the spots illustrated.

[Oztopher]

I think i'll wait for software voltage control (if there will be any) before i start pulling resistors off my card

[Falkentyne]

Me too.
And the quip about 'No soldering needed' really threw me off...it's a pot mod, so of course you have to solder....

A pencil mod would be nice, though....and yeah I don't want to rip resistors for a non reversible mod, either...

[T_M]

I meant no soldering iron required to remove the resistors.
Well, i am dissapointed to report to the die-hards that the card seems to have a problem with cold - really really badly.
Anything below 5C pot caused fireworks and below 0C was a psychadelic experience

[Oztopher]

Wow... that's...

Although, i do remember reading somewhere (before the cards came out) that the dual BIOS switch somehow also helps with a coldbug? Any news on this?

Sweet, thanks! Looking forward to more results!

[nvmc]

Running OCCT stable at the CCC limits on my 6950, not very impressive I know, but as far as I know, it's as far as I'm getting without a hardware mod.

2x 6870

here it goes:

Yeah, its normal that u have higher score with 6870's

[Barr3l Rid3r]

Yeah, its normal that u have higher score with 6870's

ahh ok, sorry haven't noticed you were using the 6850.

[Gaul]

6850 @ 1075/1200 on ref HSF

Same here !
On my Singlestage -30°C badly Pixel Error's

Here with air cooling ...

[Martin.v.r]

Bug whit Unigine Heaven x11 xtre..

cpu whit watercooling
rest whit air

Here's a video of my experience with 6970 subzero.
As you will see, below ~5C its a fireworks show but as it warms up it becomes crystal clear.

That's exactly what happens when you start any benchmark ...
I got also Pixel-errors in 2D-Mode when increasing the GPU-clock with Trixx
