overclocking i5-3470s (ivy bridge) ?

[Obe lix1]

Hello,

I have read that non-k Ivy Bridge CPUs could be overclocked by 400 MHz . The Max Turbo Frequency of the i5-3470s is 3,6 GHz . This step would generate a CPU Frequency of 4 GHz ?

Is it also possible to increase the BCLK of this CPU to 105 MHz and apply a multiplier of 40 to generate 4,2 GHz, or at least quite stable 4,1 GHz ( BCLK=102,5 MHz) ?

I already got an Z68 motherboard wich is capable to change the multiplier. The Thermalright hr-02 Macho is the planned CPU cooling system. I also like to apply quality heat-conductive paste between the cpu-die and the ihs.

The maximum multiplier on non-K/X chips is locked. They can be bumped up by three bins at the expense of disabling three cores.

Overclocking with BLCK is not recommended since it messes up clocks for tons of other components that may (silently) not like being that far out of spec.

It can be raised by 4 which affects all levels of turbo, not just single core turbo. I also wonder where you got the 3 bins from. Stock turbo for the 3470s is:
1-3.6
2-3.5
3-3.3
4-3.2
So that's 4 bins from 4 cores to 1. Or 7 from normal speed.

Humm, no.

Turbo Boost between 3.2 and 3.6 on the i5-3470 is with all cores enabled depending on available power and thermal headroom. Disabling cores unlocks 3-4 more bins beyond that on some non-K models.

No i5 3470 stock Multipliers are this
1-36
2-36
3-35
4-34
and it can go up to
1-40
2-40
3-39
4-38

Wrong cpu, 3470s, not 3470. Please don't bump such an old post. Don't you get a popup saying it's really old?

I have never seen a popup for a thread being old. Would be nice. It would save me a good deal of time. :lol:

Gotta love accidental thread necromancy.
