I don't believe it officially supports DDR2 1066 but it would certainly be benefical to have for better OC's with good ram timings and it will probably work.
The RAM I'm using I think is the same of yours, http://www.newegg.com/product/product.asp?item=N82E16820145034 (Which I'm glad I got it when it was $60 cheaper)
I don't think the RAM is the bottleneck. Right now with my OC setup I'm actually running the ram slower than its rated speed, because I wanted a 1:1 divider I set the memory multiplier to 2 from auto. The DQ6 seems to default to 2:3.
