Rampage IV Extreme wont run stock I7 3930K settings? - Page 3

post #21 of 23
As far as I know it isn't a bug, and if it is different than "stock," it is intentional.

Default settings, all of my cores turbo to 3.8GHz. As far as I know, this is how it is supposed to be, and has only worked flawlessly for me.

That aside, I push all of my cores to 4.6GHz @ 1.35VCore, which is the safe high setting for the CPU given the cooler I have and the temperatures I reach.

As I noted in another thread, you should be dynamically OCing the 3930K to at least 4.2GHz for EACH core, or you're just wasting the CPU's potential, provided you have sufficient cooling for it. Up to 70° to 75° C for the high core and 50° C for the CPU is fine. This is more than safe for the CPU fully loaded 24/7. (I keep my 3930K dynamically fully loaded crunching 24/7 while hosting a couple servers on my computer, and occasionally gaming, et cetera.)

3.8GHz per core is a slow walk in the park for the 3930K. I have my suspensions that it is intentionally reduced to these default turbo speeds to set it apart from the 60X and 70X.

Thread Starter 
agreed right now I'm not at the full potential but I was trying to get it to act as intended by Intel first before I start stepping it up so I can figure what the temps/volts/stability of the system is prior to messing with any OC settings. So as I wrote earlier regarding turbo boost is designed to work as follows...

Taken from a tech website:(physically seen this on my 2600k)
"On Sandy Bridge processors, Turbo can provide a 400Mhz speed boost in single-threaded workloads, 300Mhz in dual-threaded workloads, 200Mhz in triple-threaded workloads, and 100Mhz in applications that utilize four threads or more."

With the settings I have now I'm seeing the above scenario which is intended by Intel(albiet with two more cores now). Previous with Asus XMP at default it was choosing to ramp all my cores at 3.8ghz along with voltage 1.3+/temps 70*c ish under full load which it maybe able to handle but is not stock which is were I wanted to start to get a baseline.

This is total personal view here:

I know I bought a OC happy board full of options but thats what I should have, not plug everything up and use the default settings(XMP for Memory) and it OC the CPU settings on its own. That to me seems backwards. But now that I know how to control the BIOS for my intentions problem solved.

Fair enough (and don't forget OC happy CPU), but if I were you I would stick with the XMP and 3.8GHz turbo for each core as the baseline. thumb.gif

I am curious what ASUS has to say about it though, so if you could let us know?
