So... has anyone successfully flashed a 6870's BIOS to increase GPU/Memory clocks, voltages and Fan curves?
I've been trying to do that on a Sapphire HD 6870 (this one)with no luck at all.
After what seems to be a successful flash the AMD drivers will cause a BSOD -atikmdag.sys- and windows will stop.
Only removing the drivers and returning to the original BIOS will solve the problem.

Bumping this thread... has anyone successfully modified a BIOS for a 6870 Radeon card?
I mean modifying the original bios of the card to change clocks, voltages and fan speeds?

That's the problem.
You can flash but then you cannot install the drivers properly.

this is the bios that i was looking for, the toxic one, but if you say it gives you BSOD, then i'm afraid to flash it. Maybe the toxic version is a non reference board so some settings are different. I have a MSI reference 6870 with XFX black edition bios (940 / 1150 ) workin perfectly 24 / 7 since 5 months.

Yes, the Sapphire 6870 Toxic hasn't got a reference board. It's more like the HIS 6870 iceQ X Turbo X, i think. It seems like the XFX Black BIOS stays the best option for reference boards.

For me now the XFX Black version of BIOS is the best. I cannot find HIS Turbo X one so until i research if that one works or find it i'll use xfx bios.

by the way, i've seen that HIS 6870 ICEQ X Turbo X has the same PCB so the bios from it will work on reference cards also. Please post it if anybody has it.

My main concern is the fan profile.
My Sapphire cards get TOO HOT when playing intensive games like Crysis 2 and they shut down causing a system hang.
The only way to correct this is by using the fans at a fixed high speed or by flashing a new profile on the bios, which is impossible at the moment.

I've bought this cooler for my Radeon 6870 and the temps are between 50° and 55° C in Crysis 2 (75° C Furmark max). I combined it with the standard cooling solution. I removed the case and the radial cooler from the standard cooler and I had to grind off some aluminum for the heatpipes from the Twin Turbo. The passive cooling board was used again under the new Accelero Twin Turbo Pro.

I've seen that techpowerup has updated their gpu bios collection with some new bios also. Maybe they will find the his iceq x turbo x 6870 one too. until then i am using XFX black one. my card when i play crysis 2 is somewhere between 60-62 at max but am i using msi afterburne with fan profile at 50 %. Is loud but i play the game with high sound and i cannot hear the graphic card. Also i did not change from 11.4 preview to 11.3. Anyway 11.4 was not a big improvement from my side, the big improvement was 11.2. I am to lasy to change that now and i am using 11.4 preview.

I saw that you said you bought a new cooler, yes i like it but i want to buy another 6870 in the future and that cooler takes 3 slots and i cannot make CFX anymore. I am waiting on you guys to find the HIS ICEQ X TurboX bios file.

Why not edit your fan curve with Afterburner or Trixx?

I ever boot to dos with a usb stick using this program and some dos files. The newest version of atiflash is here.
If i screwed up my 6870 with a wrong BIOS i would use it in the second slot and another graphics card in the first pcie slot. You can boot to dos with this configuration and flash your 6870 with XFX Black BIOS.

I've testet the Sapphire Toxic BIOS from techpowerup this morning and the computer won't boot anymore. This BIOS isn't compatible with reference cards. I had to flash it back with a second graphics card.

I successfully flashed my old 6870's.... but they were reference cards. I flashed them from the reference XFX 6870's to the XFX black edition then to the MSI Bios. Used normal programs to do it. But I hear that this problem plagues allot of people. (That it won't stick when you flash the BIOS)

http://www.mediafire.com/?la86uf0d6ixout1

Enjoy.
did anybody tried MacClipper bios from HIS ? i am at work now so i cannot do that. please give feedback if you already tried this !

L.E.: I saw that for those clocks 975 / 1150 this Bios file is using 1.231 voltage. Who knows if the reference card will go up with this voltage ? Try and confirm !
