Noob overclocking P35C DS3R


I have a c2d e6750 on Gigabyte P35C DS3R board with 4gb (2x2) corsair PC2-6400 ram. I wanted to try overclocking for the first time. I only changed the CPU Host Clock Control to Enabled and CPU Host Frequencey (mhz) to 400 and left everything else at default.
I check with CPU-Z at I see that core speed is at 2400 Mhz at 6x multiplier but sometimes jump to 3000Mhz at 8x multiplier for a few seconds. Core voltage usually at 1.408 sometimes go to 1.392. Also, clicking on SPD tab, I see that JEDEC #1 and JEDEC #2 are different. #1 is at 270 MHz (4-4-4-13-15) while #2 is 400Mhz (5-5-5-18-22) both at 1.8V.
Am I doing this right? I don't know what the numbers mean. I just find it weird how the core speed fluctuates like that. PLease help noob. Thank you.

    Fluctuating multiplier and in effect core frequency is due to powersaving features like C1E or SpeedStep. Voltage dropping under load is quite common as well, I wouldnt worry much about it.

    SPD tab shows modes programmed into the SPD, the one your memory actually runs at is shown in Memory tab.

    Read the guides i linked above, will help you understand a lot.
  2. Thanks for the reply. So did I do it right? I do not see a difference from before. Should I increase Mhz?
  3. In theory, yeah. Im not sure what difference you expected to see?
