Yes, I am running 1307. Also, others here have the same card and are running it without these difficulties. Remember I have tried TWO different 4870 X2's and have had the same problems.

An interesting update - I'm having more luck getting it into Windows by experimenting with different FSB's. 400 FSB x 10 (what I use for my GTX 280 stable settings) won't work at all with this card in there. 365 x 11, 410 x10 and 420 x 10 will, although I can't get any of them stable. It's very weird that the graphics card would have this effect, isn't it?
