I see, overclocking core speeds means enabling more clocks per second, which effectively increases bandwidth—like adding a larger pipe for better data flow. However, this doesn't automatically mean you're getting more performance for every clock you go beyond the standard setting. Just because the CPU can handle more calculations or process more data doesn't guarantee a full 100% improvement in speed. I think the different CPU caches and memory speeds also play a role here. What other elements are involved? And can these be improved further, aside from adjusting memory settings?

The cache effect seems small. Refer to: http://www.tweaktown.com/guides/7481/twe...ndex4.html

It just depends on the application if all of the data that can be cached fits then making it faster won't have a giant benefit, but if it's constantly swapping stuff out then it will help. As for you pipe analogy for overclocking don't think bigger pipe think bigger pump. If there is enough water (data) for the pump to pump more it helps. If not it does nothing

These discussions revolve mainly around memory clock speeds, which can be better understood using a pipe analogy. When data is sufficiently large, storing it in a cache might be useful, and increasing cache rates could help. However, if the instruction set is limited, there might not be a noticeable benefit.

In essence, the access times will remain relatively stable, though the time needed to write or rewrite data may vary due to cache effects. This isn't as significant a difference as the core cache typically causes.

It's natural to question this, especially since you're familiar with the part. You're thinking about enhancing the overclock further and wondering if it could help improve the overall performance. It might be worth considering for a quick test.

I usually check the cores as much as possible, but if the chip reaches a thermal barrier I stop. If it only hits a wall that can't rise further, I always check the cache. If it's from a voltage perspective, I attempt the cache but sometimes it doesn't improve stability.

Ah ok. So OC he cache will increase temps and require more voltage? I'm at thermal limit on my current 4.9 (avx-2)(80c at prime 95v26.6)

Typically yes. You can attempt it, though it isn't usually a major change. Each chip behaves slightly differently, depending on how each setting influences it.

So you might just let it be. My temps are already high.
