Question, I have a i7 860 OC'd to 3.5 gh. bit when I run any tool to see my oc, like cpuid, it show my core speed at 1443.1, any ideas why this is?

I've found almost no programs will ever read the overclock correctly. Almost the only one that will is CPU-Z. And even CPU-Z will read the BCLK half a point lower than it is, throwing off its reading for CPU and memory speeds a tad.

speed step, either diasable it, or put the PC under load, that is all the issue is. it is a power saving tech, which lowers the multi when there is no load on the PC.
 
only Evga boards have the .5 multi issue.

on the 860, depending on BIOS and board, Speedstep and turbo are connected, so I would leave it the way DS shipped it to you, but, lol what you are seeing is one core overclocked to the higher level, while the others are not, which you can't see on Cpuz, it only shows core 0's overclock, but core 1,2,3 will be lower, the way it is shipped from DS. you can turn speed step off, and change the multiplier so that you have the higher overclock on all 4 cores, but this will require some voltage adjustment. 
by the way nice chip, good overclock with very low voltage.
