Hi all,
I currently have an XFX 6950 2GB reference model (HD-695A-CNFC to be exact). I recently flashed the BIOS to a 6970, though it was quite a complicated process:
Read the guide, which said to use a Sapphire BIOS, but I thought it's an XFX card why not use an XFX 6970 BIOS? So I flashed it, and then whenever I tried to do something (i.e Furmark) my system crashed. So I flashed back to the original firmware.
Then I read that it might be better to just unlock the shaders then manually overclock to 6970 speeds. I unlocked the shaders, but my card wouldn't let me overclock it to 6970 speeds. So I just thought may as well try the Sapphire BIOS, flashed that, and it's been working fine since.
I'm still not sure if this is the best option - most of the information I can find it from 2 years ago.
Now I'm planning to buy another 6950, unlock it to 6970, and crossfire them. I could buy a graded version of my exact card for £122 from videocardshop, however I'm not sure if it's worth paying that much when I could get a used 6950 2GB for cheaper. But then the question of whether I could unlock it comes about. Again, a lot of the information I can find is very old, I find some places saying ONLY reference models can be overclocked, but then other people succeeding with even 1GB models. The most informative post I found was this one: http://www.overclock.net/t/1183936/which-6950s-can-i-unlock/20#post_15941454 however it is very old so the info could be outdated.
So what I'm basically asking is... Have I unlocked my card the best way, and what card should I get to crossfire it with?
Thanks a lot.
