What does ring ratio do?

[CatzRuleZWorld]

Since nobody wants to answer my thread about how to go about setting up my ring ratio for a better overclock, can someone just tell me what the ring ratio affects? Is it only for performance or does a higher ring ratio make for a more stable overclock without having to up the voltage much?

Ring ratio is just the CPU Cache speed the closer you can get it to be the same as your CPU speed the better it is overall.

@ProKoN I hope I'm right about this.

Ring ratio is just the CPU Cache speed the closer you can get it to be the same as your CPU speed the better it is overall.

 

In some benchmarks you can see an increase.  Day to day use, not so much.

 

Get you max CPU ratio then increase ring if you have the thermal headroom or just leave it.  You won't be gaining/missing out on much either way.

I may be wrong about this, but I believe that ring ratio is the speed of the interconnects between the cores, cache, memory controllers, and some other parts.. 

 

As for overclocking, my understanding is this:

-Higher ring clockspeeds decrease stability (especially if Cores and RAM are also clocked high).

-Higher clockspeeds improve performance, but not as much as overclocking the cores.

-Having a Ring speed higher than the Core speed does not improve performance

 

Basically, a 1:1 Core to Ring ratio is ideal, but can decrease stability. Having the Ring clockspeeds slightly lower than the cores is good enough and should allow you to push the cores farther.

 

Ultimately, if you're running at 4.3 Ghz Core and 4.3 Ghz Ring, that's good. If lowering the Ring to 3.5 Ghz allows you to push the Cores to 4.5, it will perform better, even though the Ring is slower..

-Higher clockspeeds improve performance, but not as much as overclocking the cores. (I'll try to look this up, but I believe that a 700 Mhz overclock of the Ring roughly equals a 300 Mhz overclock of the cores, as far as benchmark performance is concerned)

This is 100% correct. When OCing haswell, core is always king. It is best to get your core clock to the stable speed that you desire, then work on pumping the rest of your system up to match it. My G3258 is stable at 4.2ghz 1.15vcore with cache at x32, but the moment i up my cache to even x40, it is unstable.

 

Some people have even found that increasing your cache voltage to 1.1V or 1.2V, even when leaving it at stock multiplier, can improve stability when going for higher clocks on your core multi itself. OCN still has that haswell OCing guide that goes into details on this subject.
