Guys thanks for the comments.

Oj101, I think I'll think we'll stick with the ram we used as we know what they can do. I would like to try and increase the NB under Windows 7 and aim for 4300 in XP. The cooling pot I had worked really well, but I'm really impressed with the F1 Gemini not just because it worked so well, but getting a proper mount is pretty easy.
