Overclocking and 64 bit OS

I know it is bet to install any OS at stock settings, so my question is if I plan to use Windows 7 64 Bit as my OS will I be able to achieve the same OC that I am running now once it is installed?

Also I will be adding 2 more of those G Skill 2GB DDR2-1000 dimms for a total of 8GB RAM. Main rig in sig.

I've got windows 7 x64 installed on my back-up rig. It's an E8200 (ES) oc'ed to 3.2Ghz with stock voltage. No problems at all ocing. Runs extremely fast and P95 rock steady stable.

I'm sure you won't run into any issues. I did install win7 @ stock speed just to be on the safe side for fear of corrupting files during the install. Once it was all installed and updated, I started ocing

I've been running my Q6600 @3GHz from the get-go and just do everything at that modest OC, including BIOS flashes and OS installations. So far, so good
