The best PCI-E OC setup for i7

I'm not sure if it's the correct section, but here it goes...

As you know, it takes high PCI Express frequency to break 222 bclk wall for Core i7, or at least helps with that.
But people get different results overclocking PCI Express bus. I believe it depends not on the motherboard, but mostly on the graphics card. However, I'm not sure.
So, I think it'd be interesting (and fun :D) if people posted their:

1. motherboard manufacturer and model;
2. graphics card manufacturer and model;
3. the highest PCI Express frequency achieved, obviously;
4. bclk [optional, though!].

In this case, we can find out the preferable setup for reaching high PCI Express frequency, and, hopefully, high bclk for Core i7 CPUs.
