Guys, I need some advice on a few things about the radeon HD 6950 GPU that I plan on getting.
The things I need to know are:
1.Which manufacturers make versions of this gpu that can be unlocked to the full 1536 shaders successfully without turning it to HD 6970 GPU? (as high power use is an issue for me)
2.Which versions of the card can be unlocked and turned into HD 6970 is that's my only option successfully?
3.Is it better to unlock more shaders than it is to OC?or are they both as important to boost mining MHash/s rate?
4.I found a card that I'm not sure about that can be unlocked:http://www.amazon.co.uk/dp/B004ULFWAI/ref=asc_df_B004ULFWAI3344652?smid=A3P5ROKL5A1OLE&tag=googlecouk06-21&linkCode=asn&creative=22206&creativeASIN=B004ULFWAI
I found this to be the cheapest I can find,but can this card be unlocked with just BIO update (just modded bios without turning it to HD 6970) or does this require some soldering as reported in a few cases as well?
5.Is there a BIOS repository,or a help section on here or on the net where I can look up the right BIOs file?
6.Which tools are needed to flash it?
7.If the card I find isn't very good or unsuitable,can you please find me hte cheapest suitable GPU that can be unlocked without soldering or anything too complicated/risky for the UK?
Thank you guys and I look forward to your reponses.
