New Build, Slight Problem with Heatsink & Memory

Hey Guys

I have just built a new PC with a Gigabyte GA-X48-DS4 Mobo, a Q9450 and Corsair TWIN2X4096-6400C4DHX 4GB (2x XMS2 2GB) PC-6400 (800MHz) 4-4-4-12, and an Arctic Cooler Freezer Pro 7.

I have just one problem. When I install the heatsink and then try and put the Ram into Banks 1 & 3, the heatsink on the Ram in Bank 1 touches the Arctic Freezers plastic frame around the Fan. Is this a bad thing? Would there be any problems leaving it like this?

At the moment, because of this, I have put the Ram into banks 2 & 4 and everything works great. I wanted to upgrade to 8 GB however and I was wondering if the issue I have above would be much of a problem. I guess I am worried about the plastic on the Arctics Fan (the frame only, not the actual fan) might melt. Do you think this would happen.

I can easily put the Ram into bank 1 as it only just rests against the plastic.

Thanks.

P.S: If anyone is using the same CPU and Mobo could you tell me what setting to change in the Bios to overclock it a little. To perhaps 3.0 or 3.2 GHz. Thanks. I am trying to learn about Overclocking but most of it is just going straight over my head. I just don't know what settings you actually change in the Bios to increase the speed.

Thanks.
