RAM speeds on new homebuilt computer.

I built the computer from a thread I made in the other subforums, and things have been going well. I do have a few questions though. I don't want to do any overclocking of the CPU, which is an i7-950@3.06Ghz, at all.

In the BIOS, it shows the CPU speed as around 3.2GHz? It appears that there is a bclk value of around 133MHz that is automatically being added without me touching anything. In Windows, however, the CPU is being recognized as 3.06.

The other question I have is about the RAM. The RAM I got is 1600MHz, 1.65V, 9-9-9-24. However, the Gigabyte x58-usb3 recognizes it at 1066MHz. I changed it 1600MHz and adjusted the timings accordingly,and the VDRAM shows up as 1.648 in the MIT screen. On this screen, the VCore shows up as 1.248V.

If I go into the advanced voltage menu, I have, CPU VCore = 1.275V, QPI/VTT = 1.175V. I read that VDRAM - QPI/VTT should be less than 0.5V. In my case, the difference is very close, at 0.47V.

This worried me a little, so I went back and changed the RAM speed to 1333MHz, and the VDRAM is now at 1.58V, which seems safer to me. Can anyone give me advice on whether I should keep the default 1066MHz and be the safest, keep it right now at 1333MHz, or revert it back to 1600MHz (in this case, are the values I listed appropriate)? I don't want to damage the new CPU in any way.

Thanks for any help.

My idle temps are running 29-30 across the board, if that is helpful information.
