Anyone know anything useful to tell me about saphire trixxx while I'm at it? I'm reading reviews that say it moves the card from the 6950 numbers to the 6970 numbers automatically. That sounds pretty good to me as I've never messed around with oc'ing before.

Also reading about card with dual bios and people switch to the second bios and it's automatically unlocked???

Been looking at these, but I can't seem to find if a card actually has the dual bios or not. It doesn't seem to be listed (that I see).

Thanks.

Alright, stupid question if you can just straighten me out here...?

I'm looking at 6950's and I can't quite seem to get my little, tiny head around something. When I look at this picture and most others I'm running across...I feel like the pretty cover is going to be on the bottom of the car when I install it. Am I just visualizing this wrong? I'm trying to picture the side that inserts into the motherboard and where the external connections are for the monitors, and I just keep thinking the pretty side will be down. That doesn't make sense...HELP.

SAPPHIRE FleX 100312FLEX Radeon HD 6950 2GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity

it's done at your own risk. The first thing we need to do with our system off is to switch that handy little tab on top of our HD 6950 to the number "1" position. What this allows us to do is flash the BIOS.

Once that's done, we fire up WINFLASH which you can download at TPU
and make a backup of our current BIOS. With that done, we then proceed to flash our card with the Sapphire HD 6970 BIOS

First to do navigate to where WINFLASH is. I recommend you throw it in your C: just so it's easy to navigate to. Once that's done, typed atiwinflash -unlockrom 0. From there typed in atiwinflash -f -p 0 Sapphire.HD6970.2048.101124.bin. at recommend that you change the BIOS name, though, to something like HD6970 so you don't have to type as much. Once we had flashed the BIOS, we were prompted to reboot and did so.

So even if i am able to get a card with a dual bios, there's still a risk of ruining the card?

I'm not sure about that Sapphire card but my understanding is that Diamond has an HD69502GB that has been *pre-flashed* on the second BIOS to an HD6970.

And while I imagine some folks have had problems there does not seem to be any substantial number of totally borked cards. By simply flipping the switch you may restore the stock BIOS.

If you do unlock bios will different with manufacturer default, .. think about warranty , how can you get guarantee.
Overclock still safe because you had switch dual bios.
You much search many recommend about it in out.

Don't flash a 6950 with a 6970 bios.

You can unlock a 6950 even if it only has one bios. just find a 6950 unlocking tutorial on google.

all you do is copy your 6950 bios, run it through a .bat program to unlock the bios which will give you a changed 6950 bios, you take that and basically upload it back into your card. give it a good 5-10 minutes, if it doesn't restart, but it seems done or frozen, restart it yourself.

Your Answer:
Matthew,

Glad to hear you were able to resolve the issue. The 790i is capable of running AMD cards in Crossfire. If you have any further questions please contact us again.

That's what I just received from EVGA. I think I'm going to go for the toxic 6950's with dual bios that unlock to a sort of 6970 with a flip of a switch.

Recent tests performed by our very own Thomas Soderstrom confirm that the Radeon HD 6900-series features vastly improved scaling performance in CrossFire compared to previous-generation boards. As such, a pair of these cards represents a realistic pinnacle for our recommendations. At $530, two Radeon HD 6950s handily beat the GeForce GTX 580, and even come very close to catching the pricier Radeon HD 6990 and GeForce GTX 590.
