Hi, I am new to this forum and I got here by following this old guide: http://www.overclockers.com/3-step-guide-overclock-core-i3-i5-i7/

I got stuck on the third paragraph of the Bclock voltages. I have been taking notes on how to overclock and its getting really confusing for me. I have a basic understanding of what I am doing, but when it comes to memory timings and voltages I am having trouble because I am using an old DP55SB motherboard paired with an 875k. Due to my limited knowledge, and these devices being one of many i7 processors/motherboards released, I am getting confused on what I need to do to get stable overclock, as things are different in my bios.

Here is the tuning guide for my board. http://downloadmirror.intel.com/18129/eng/performance tuning guide v1.4.pdf

It doesn't really say much.

I have overclocked my processor to 3.82ghz before using a mulitplier of 26 and blck of 147. I also had my voltage at 1.300v, but I started noticing that I was getting blue screens doing the more normal tasks on my computer, but not when I was running AIDA64. I am using a h75 cooler on my cpu and my temps seem to be fine and at stock I am getting 64c under full load. I was just wondering if anyone could help me out, as I need this overclock, and I would also like to learn a thing or two. There are so many different terms for everything my heads spinning:confused::bang head

That motherboard has some OC options but not all. When you upped the BCLK did you drop the memory multiplier?
That CPU has an unlocked multiplier (iirc) so maybe it would be easier for you to just up the multi and test. Then you don't need to worry about the other busses
