i5 4690k OC and Cache ratio

[aquilaray]

So I overclocked my i5-4690k to 4.4Ghz at 1.75v, it is stable at this point after stress testing (AIDA64 and prime95) now I tried to set the cpu ring bus to same multiplier and voltage (4.4Ghz and 1.175v) but that isn't stable anymore.

Should I higher my Ring bus voltage or lower the frequency? I read somewhere u should keep your ring bus voltage always below core voltage, is this true?

Ring ratio should not exceed core clock speed, from what I know it should be kept as close to the core clock speed as possible, but running it slower doesn't affect performance much. Many people don't even touch that setting.

But what about the voltage of ring ratio, may that exceed core voltage?

I wouldn't touch that if I were you.

I've experimented with the Ring Bus speeds on my 4670k and never found a real correlation between speed and performance beyond a small percentage. In fact benchmarks often went down the higher I went along with a lack of stability. Cap it in the high 30s if you want, but I wouldn't run it much past x40.
