i7-7700K Cache Frequency?

[Nicodemus_MM]

Greetings,

I'm a long-time lurker on this forum, but only recently registered.

I have a question regarding the cache frequency on the Kaby Lake line, specifically the 7700K. I'm not sure what the optimal ratio should be. I don't recall seeing anything on ARK and information seems limited or suspect due to how new the line is.

I may have won the chip lotto again and prefer not to screw this up. Currently I'm at 4.9 GHz on 1.25v with 4.5GHz on the cache. I'm still testing for stability, but thus far things are looking good.

Is there a definitive answer on the Core to Cache ratio or is this somewhat flexible?

Thanks in advance,
~Nicodemus

From reading this post https://hardforum.com/threads/overclocking-guides.1921585/ it looks like through testing that the cache frequency only affects overall performance by a miniscule amount. Increasing the core speed has proportionally much more impact on the performance.

Exactly what KIAman said. It's just like Skylake. After you stabilized your core clock, match the cache multiplier and retest. If it's stable, great. If not drop it down 1x and try again,
