overclocking bus

[thatguyjerry]

While I was running a stress test for my CPU OC on OCCT I noticed there wasn't any percentage increase under bus. Looked into it, and, if I understand correctly, overclocking the bus should increase the performance of the system as a whole? So, how do I overclock this (or can I overclock this)? My specs are in my signature

Ignore Cache/Ring Bus overclocking.  It doesn't improve performance, and only causes extra heat and instability.  What I recommend is set it to whatever stock speed is.  For instance, the stock cache speed on my i5-4670k is 38, so I set min= 38, max = 38, adaptive voltage = 1.050.

I was hoping to see a school bus with NOS.

Ring ratio also kind of confused me. I've actually bumped by OC up to 4.5 Ghz with my most recent stress test, should I bump up the ring as well?

This has now become a life goal of mine.

Ring is cache.  Ignore it.  It doesn't improve performance and only causes instability.

The only real reason you should touch that is if you have a non-K cpu and want to squeeze a bit of an OC out of it. You can't bump it up too far, and it can cause stability issues with PCIe I've noticed, even if it's stable for the CPU stress tests.

Ahh I see, that makes sense. I'm still looking for some info on ring ratio as well

You don't need to, crappy cache can be very painful if you OC it...

 

alright, one last question. 1.35 is good voltage correct? It will be on adaptive, but the slight increase under load can yield better results?

General rule with intel as far as I know, and I'm no overclocking expert, is you can usually expect to get to 103-105ish, 100MHz being default. It's generally not recommended to pass 105MHz due to stability issues with PCIe, and even below 105 you still need to run tests to make sure everything is A-OK.

However, I was able to get my i7-2600 non-k from 3.4Ghz with a turbo with all threads coming in at 3.51Ghz to 4.056Ghz despite only being able to raise the multiplier to 39 by setting the bust speed to 104Mhz, so I got a 125-150Mhz or so gain from boosting the base clock over just the multiplier, and a total of a 15.5% overclock.

uh...

What frequency and CPU?

 

It's in my signature. I'm pretty much just squeezing a pentium g3258. It's running a stress test at 4.5 Ghz at the moment, and I'm just curious about some voltages
