Unigine Heaven 2.1 BenchmarkThe Unigine Heaven 2.1 benchmark is a free publicly available tool that grants the power to unleash the graphics capabilities in DirectX-11 for Windows 7 or updated Vista Operating Systems. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. With the interactive mode, emerging experience of exploring the intricate world is within reach. Through its advanced renderer, Unigine is one of the first to set precedence in showcasing the art assets with tessellation, bringing compelling visual finesse, utilizing the technology to the full extend and exhibiting the possibilities of enriching 3D gaming. The distinguishing feature in the Unigine Heaven benchmark is a hardware tessellation that is a scalable technology aimed for automatic subdivision of polygons into smaller and finer pieces, so that developers can gain a more detailed look of their games almost free of charge in terms of performance. Thanks to this procedure, the elaboration of the rendered image finally approaches the boundary of veridical visual perception: the virtual reality transcends conjured by your hand. Although Heaven-2.1 was recently released and used for our DirectX-11 tests, the benchmark results were extremely close to those obtained with Heaven-1.0 testing. Since only DX11-compliant video cards will properly test on the Heaven benchmark, only those products that meet the requirements have been included.

Perhaps you just got unlucky?. Either way I liked your review.
Glad you liked the review.
That or maybe it's not actually adjusting the voltage.
Anyway, if you can re-check and try to modify voltage, that would be great, because that could mean GIGABYTE is making a different version (revision) with another GPU controller.
Thanks.
Another strange thing, the factory original bios set the coolers to run at 73% and ofcourse the sound level was realy anoying.
GIGABYTE doesn't display any BIOS update for this model, but I've checked and there's a BIOS update for the non-OC model.
Yes on the Gigabyte webpage ,is a new BIOS for "basic" Gigabyte HD 6850 cards (775/1000).This arrived at 14 january 2011 .As I mentioned in my previous post the Vram clock and the cooler speed was changed (Vram from 1000 to 1005 and cooler from 25% to 40%).Unfortunatelly doesent solve the black screen problems for everybody.Some users reported the BS with this bios version to.
Well, I'm still using this little puppy and it's not giving me any problems. Could you tell us what are the conditions or signals before going to black screen? Perhaps I could try.
The problem I meet undert FarCry2 benchmark ultra high settings full hd dirX10, Crysis- paradise lost level ,GTA4 and NFSShift
(all games full HD aa8x vsync on)
The GPU temperature never exceed 68C.
Far Cry2 bench ~ 55C , Crysis 67 C, GTA IV 68C.The RAM temperature I dont know because I dont know any software which can mesure this.There is some rummors which say the memory are faulty , but I dont want comment this because until today I dont see any official evidence as the Hynix memory cause this problem.
I check my card temperRATURE with ccc OVERDRIVE, aida64 and MSI AFTERBURNER all programs show me the same temperature so resulting the heat level is ok.
The F3_C bios fom 14 january seems to resolve the BS problem to me but I am not calm at all because I know a couple of users which card
is faulty with this BIOS version to.I atach a couple of videos what I find to youtube.My system (and my buddys sitem ) behaviour is 100% the same.
None of us overclocked her card! every card working on factory clocked level 775/1000 1,5 V.
Many serbian, hungarian, romanian (but not only this country) forums is full with users who have exact the same problem.Most error was reported with have
gigabyte cards , but is other vendors card which have this BS NO Signal problem too. Asus,Saphire,MSI ,etc
I will atach a couple of youtube videos to see what I takling about

Here is the link with the new BIOS.If somebody have the same problem he can try it maybe will help but not 100%.And once again! the cooler rotaion will become 40% (original os 25%)and the memory frequencies will rising from 1000 to 1005 Mhz.This BIOS is only for GV-R685D5-1GD cards. I dont dont know why was necessary this modification but to be honest I like att all,especially after saw a couple of the same cards ,which working perfect with original BIOS(775/1000, 1,5V ) and doesent make Black screen error.

Mine has been OC'd to 950/1200 on stock voltages.
Ran OCCT for an hour with no errors detected.
Did a memtest for a whole night with no errors.
My problem is after playing CS:Source for more than an hour..my computer screen turns black and shows "No Signal" and at the same time my computer freezes and the sound just keeps repeating the last thing that was heard.
I can't do anything but do a hard reset..and now I notice when I boot up Windows there's an extra black screen with a messed up windows logo right before Windows actually loads up.
CS:Source FPS average around 299

I might revert back to the old beta 6 later when I get home and do some more gaming to see if that fixes the problem...
On AMD software by checking the box to enable Graphics Over Drive:
Automatic OC options on AMD Vision Control Center are:
GPU range: from 600 to 985 (just drag the bar)
MeM range: from 1050 to 1260 (just drang the bar)
My question: can i safely drag to 958 and 1260? as they appear as option to me?
very good review by the way
