1st Gen i7 overclocking

I have an Intel Core i7 975 extreme on an Asus P6X58D-E motherboard and 12 Gigabytes of Super*Talent ram that operates at a frequency of 2000 Mhz. I have raised my BCLK frequency to try to get my ram to operate at the speed of 2000 Mhz but the problem is... that I have hit a wall.. I am wondering if I can get the ram to run above the 1805 mhz its currently set at. I will post screenshots if needed. I also have plenty of PSU wattage to play with.

Did you read through the guides for the chip here?
