    Yes, you likely would! QPI/Vtt and Vcore

    You could lower the CPU Multi if you didn't want to run 4Ghz, that would allow you to not have to raise the voltages so high

    Ok. Left the CPU voltage alone, changed Memory Voltage 1.6V. IMC Voltage 1.2V. CPU is at 16x giving me 2.66mhz. Decided to go with 1666 memory speed for the time being. Changed bclk to 166. This looks good I would assume.

    Sounds good if that is what you want to run. Do some stability test though to be sure you still do not need to adjust things.

    Here is a modified template (as you don't have one for p55) of my settings. I am back to non-overclock settings for the time being. The goal is to try to get the RAM up to 2000 with little to no CPU overclock. I was running at 3.5ghz / 1700 ram speed last night, but the watts was from 50-120, which is very high and I did not like that. Maybe you can suggest the settings looking at this template. I am not sure the benefits or short comings of setting the cpu clock ration to 13x, bclk to 200, giving me 2.6 GHz, and 2000 Mhz on the memory. Not sure the downfalls of running such a slow clock ratio.

    Ya, sorry I have just not had time to make one out for P55 and add it to the template thread yet. I will try to get that done this weekend as I see more and more P55 users already :)

    Only you could compare what setting CPU Clock lower to 13 and running 2.6 would do, but it would likely be hard to really compare with anything because other ways to reach 2.6 would not give you the same uncore/qpi/memory so the comparisons would be skewed

    I am not sure what you are asking about with the settings you listed, and many of them do not coincide with your thoughts mentioned?

    13x200 with ram at 200 seems like it is the only way you could run CPU low with ram at 2000, so looks like you need to test those two and compare things.
