Core i7/X58 Overclocking Thread

[dejanh]

I am having a problem with this. You are saying that 4 / (9/8) = 1.777. But that is wrong. It would have to be 2 / (9/8) for the resulting quotient of 1.777. 4 / (9/8) is 3.555.

Am I just missing something here or is there an error in your math? Either way please let me know because I am very confused.

You are right...my bad. I know what I was thinking, but I wrote it down wrong.

In my testing I showed that Uncore higher than 4.0GHz was unstable, and particularly unstable if it passed QPI maximum of 4.0GHz. Therefore, I assumed an upper Uncore limit of 4.0GHz. Since Uncore is 2xDRAM then max DRAM is 2.0GHz but going by the safe Uncore:QPI relationship that would make max Uncore 3.555GHz which is 1.777GHz memory.

I think with lower overclocks you can run memory higher and still be stable as the overall stress on the IMC and other components is much less.
