I've recently purchased a Gigabyte HD6850 1Gb.
I have to admit the selling point to me was the Twin Razor fan, seemed the best stock cooling option at the moment, and was lured by low fan noise. However after installing the video drivers I noticed the fan idles jump up a noisy 73% speed. I haven't used RBE Bios Editor so far, and with CCC i tried to set fan speed to manual but it doesn't seem to work for some reason.

Before I try other options like afterburner or customizing the fan-speed with a bios tweak I would like to know the impact on changing fan speeds on fan lifespan. Anyone else with this card with the same issue? I'm currently using Catalyst 10.10C. If the best approach would be a bios mod I'd also like to do a nice safe overclock as long as I'm there. (as I plan to use this card for a long while now). Any ideas are welcome.

Thanks

Ok 1st time I update video card bios. Before I do something stupid I want to ask:
I saved my current bios using the lastest gpuz it's 128kb, but the vga_bios_gv-r685d5gd_f3_b I downloaded from Gigabyte is only 64kb. Should I worry? is there something wrong? What's the next step?

Edit:
This seems to work atm, I dont know why I cant control this from CCC.

Do you mean like this...

The card is completelly silent in idle (on desktop), when you run a game, the fan fires up at high RPM and then slows down again to silent? I had HD4870 from Sapphire that worked this way.
And only way to stop this crap was manually modding the VGA BIOS and changing fan parameters.
That solved it. The parameter for this is "Fan spinup" and anything related to it.

No, my problem is that the fans are constantly running (though humming would be a more accurate word for it) at 73% RPM, regardless if gaming or in 2d desktop mode...

Same problem here with that fan noise and double sized rom bios file.

Well. I tried flash that bios file from Gigabyte sites but with last ATIFlash v3.79 I get error adapter not found. Error 0FL01

Any idea how flash this card? Thanks

So far using afterburner, I dont like having an extra program in the background however. Any insight from experienced members of the forum would be welcome.

Edit:
I did send Gigabyte a ticket on this issue, asked them about the BIOS size difference and asked what program would be best used for flashing it if safe. Waiting for their reply

Well Gigabyte answered the ticket finally, said there's no reason to worry about the size mismatch. I highly suspect this ticket was answered by a script though the reply was highly generic.

New member here but long time ATI/AMD gpu user. I have a giga hd6850 which is working flawlessly. It is a beautiful card, small, power efficient, silent and powerful. I am running CODBO on it on high settings at high fps. What I did?

First, DL the bios update from Gigabyte and flash the card. ATIflash won't work. You need to use @bios to do this, the Gigabyte proprietary flash utility you can use either for their cards or their motherboards. Just DL @bios from Gigabyte (or google "@bios"), run it in Windoze, locate the bios update (if I remember correctly, its not in .bin format) and hit flash. Works perfectly.

Then, use CCC (afterburner etc no good because don't use morphological anti-aliasing etc), but make sure you install the latest hotfix (d), which you can google as well. Its a big file over a hundred meg. If you then set a profile for slight overclock, with most 3D set on application control, and leave the fan on auto, even on a very demanding game like CODBO, it will only get up to around 50C or so. Such a cool card, and silent, compared to the POS Sapphire HD4870 I had previously.

Trust me, the bios update fixes everything and then with the latest CCC/drivers, hotfix d, you are up and running.

Cheers

@BIOS not updating

I'm having trouble updating my Gigabyte 6850 with the @bios utility. I have the latest version, and I've downloaded the bios image from the product page, but when select the file from within @bios I get the following error: "Can not load ROM image from BIN file. Maybe BIN file size not match".

Any ideas?

Thanks

Yo. Are you using GVFlash.exe, rather than the motherboard @bios? If so, I had no such trouble. Its not a .bin file anyhow afaicr. On my @bios, it shows as "GV-R685D5-1GD F3_B" with no extension, EEPROM size 131072 bytes. Perhaps you haven't opened the bios file that you downloaded? You download an .exe file, which is packed, then open that to the folder of your choice. It unpacks to "vga_bios_gv-r685d5gd_f3_b" with no extension. It is not a .bin file.

Hope this helps

BTW, mild overclock of my card, latest bios, on an X48 mb, and I just finished Crysis on ultra, middle of Warhead on same settings, about a third of the way through Starcraft 2 mostly on ultra with no lag, and had no problem at all with high settings for latest MOH and CODBO. Beautiful card, just beautiful.
