Philosophical question - 4.4Ghz vs 4.5Ghz

post #1 of 3
Thread Starter 
Hi,

I have a weird situation going on.

I'm still using my trusty old 2600k processor, bought when they got released back in 2011. Anyway, I was using the CPU for the last 4-5 years at 4.4Ghz, overclocked with Dynamic Vcore (Offset mode) to use 1.320v @ 4.4Ghz, which offers me both great temps and a nice, low, safe voltage.

A few weeks ago I experimented with 4.5Ghz, and it crashed in Prime95 or the x254 benchmark all the time. It finally settled at 1.380v for 4.5Ghz.

Now, is this kind of voltage required jump normal (0.050v for 100Mhz)? Maybe 4.4Ghz is the ceiling my CPU wants to operate at? And would you use the 4.5Ghz, or revert back to 4.4Ghz since it seems to be much more beneficial to the health of the CPU?

What weirds me out is that even if it's just 100Mhz, I did notice it was somewhat faster. It was noticeable. My RAM is at 2133Mhz CL11, so maybe the RAM benefits from the higher CPU frequency? Not sure what to do here...

Cheers!

Just leave it at 4.4 Ghz for longer lifespawn

4.4 is fine, if you want to overclock, try getting your ram at 2400/10 or 2400/9 smile.gif (won't change much, but it's fun!)
