**Official** Core i7 860/870 overclocking thread

[Scaniris]

Yes maybe something else: I don't use this setup for daily use!! I'm concerning with power consumption and earth care. So I usually use a dynamic OC, with C State, Speed Step and Turbo Mode on, Bclk @ 166, mem @ 2000MHz 8-8-8-24 1,65V. I have more power when needed only, but also downclocking depending on the perf requirements. And I'll also test a 2 cores only cpu, because I don't see any application (except maybe Premiere...) that take benefit of 4 cores, I have more benefit with higher clock speed, I'll check this. Because.... with 2 cores only, you can get 4 x 133MHz increments with Turbo Mode on. 5x with a single core. So...

Bclk @ 166 - 2 cores - Turbo mode on - Native cs @ 3486MHz - Turbo cs @ 4150 = under the maximum TDP for the i7 860.

With such a reference clock setting, I can use the mem @ maximum stock frequency/latency/voltage values, and get only when required some additional clock speed, keeping benefit of SpeedStep and downclocking.

Well it's theory, but I will test it this evening for sure With application to monitor real load and compare for example compression time for a video, or audio file. Because this is my daily use: gaming, audio, video... not benchmarking And the benefit of a higher clock speed is probably higher for my apps than having 8 thread parallely, I don't know if my apps are able to use so much power.
