Hi guys,

Finally got my pair of Sapphire 5870's after 3 weeks of waiting, i have to say it was worth it no doubt. First thing i did was flash the bios with the MSI.rom it was pretty straight forward but i was a bit worried considering it was my first time doing it (could have been a couple of expensive paper weights). Didn't take me long though till i got frustrated and annoyed that I could not get the cards stable @ the magic 1GHz considering i have been following this thread for a while now and seeing how many of you have.

Have a look at the Excel data i collected my card hates any extra voltage over stock and just gets worse as the voltage is increased.

I have got a lot more to say but i have been up for 40hrs and really need some sleep so i will just let my screen shot do the talking.

I am a bit worried that my Enermax85+ 850w isn't going to be enough for my setup what do you guys think.

Will follow up with more benchies tomorrow.
