Overclocking i5 4690k

i5 4690k

sabertooth z97

16gb 1866

 

cpu ratio: 47(synced)@1.2V

dram:2000mhz auto voltage

 

I set cpu:dram ratio to 100:100(1:1) but cpuz shows 1:10. Why??

 

What min/max cpu cache should I set  at 47 cpu core ratio and what voltage? At this moment cache and its voltage is auto.

That's actually a very good question I'd like to be answered since I use the same CPU and have the same problem ^^

I think that at 47 core, cache ratio should be at 44-47 but I cant imagine with what voltage.

Did you find any answer about cache ratio?

[Tytan64]

No, I didn't really.

But I played around with it and did some benchmarking!

I changed to cache ratio from 39 to every possible configuration up to 45 while running 4.0GHz, 4.5GHz and 4.7GHz and I couldn't even see differences in Cinebench 15.

Gaming wasn't affected either.

So I will just let it untouched. Maybe that's something more important for CPUs with more cores and more cache.

I hope this helps you =)

 

4.0GHz at 1.100V

4.5GHz at 1.200V

4.7GHz at 1.300V

 

I will use the 4.5GHz profile in the winter and the modest 4.0GHz profile in the summer

Thank you for the reply!

 

I m going to leave to "auto" too. Thank you for the info.
