Cache clock speed, does it really matter?

[Guest]

Hi all.

 

So, after several months of owning my CPU, I'm still fine tuning my overclock. I found that with RAM at 1600, my CPU does fine at 4.4 GHz with 1.250 vcore. However with RAM at its XMP of 1866, I need a bit more vcore to be completely stable. I want to keep my XMP, so I thought I'd push my vcore to 1.3 and push my cores to 4.5, because if I'm going to increase the voltage anyway I might as well get what I can out of it.

 

My question is, should I bother overclocking my cache speed or not? I've heard a lot of mixed opinions on this. Is it possible overclocking my cache will take away from my core stability?

It helps a tiny bit, but not very much, more in benchmarks, rather than games. 

It shouldn't hurt core stability, but it can affect overall stability.   

 

IE:  Running stock cache vs OC cache, you shouldn't need to lower your CPU multiplier to get a higher cache ratio to work.   (In my experience at least.)

Don't know if this helps you but on my AsRock board in the BIOS it says cache speed should be no higher than the clock speed.

Thanks for the input. Does cache voltage affect temps a lot? For example, if my cache voltage is 1.3 would I see a large increase in temps?

Either way your going to see an increase in heat but if u have good cooling you will be ok.

I only have an evo 212 which is why I want to be careful. With 1.3 vcore, I'm okay at 65-70c max

I think its different as Haswell chips have the voltage regulator built onto the  cpu which made them get hotter than say skylake 6600k which I run. I know with Haswell Refresh they did sort the Thermal Interface Material so it made it cooler. The Evo 212 is a well renowned great cooler. Maybe give it a go and see if the heat rises but don't leave your computer while u do this just sit by it for say 15 mins while you test what u amended.
