So I decided to take a look at the BIOS settings and I noticed that the Intel turbo boost technology option was not enabled.
I’m assuming that this BIOS option allows the i7 920 to OC its self to the 2.93. Is this correct and would I create any problems if I enabled this option in the BIOS?
I don't think it will "kick-in" if it's Disabled.
It should work fine if you Enable it. Mine came Enabled from the factory and has never caused a problem. Try it and see how it works.
So I Enabled it and one thing is for sure the fans seems to spin up a bit more now.
I also downloaded CPU-Z to see what the speed of the CPU was (as I dont want to OC it, I just want the Turbo working) however, it showed that CPU Core speed as 3378 Mhz.. Is there a reason for that? I would assume that it should show the stock speed?
Each core has its own multiplier, which can and does differ from core to core at any moment in time. I believe that is the SpeedStep or other power saving tech. On an i7-920, all cores have the same turbo frequency. That doesn't mean that they all run at the same frequency, all the time.
CPU-Z is good at identifying processors, but seems to lack functionality for monitoring all the cores ... after all, isn't it only monitoring the first core (in the lower left corner)? However, "stock speed" is shown on the Specification field.
... try TMonitor instead.
Also, I think you must run something processor extensive concurrently to see high results.
So Im still a bit confused. I enabled it but now it seems that my i7 920 is clocked at 3375ish. I guess turning that option on alos OC's the cpu and does not just enable the CPUs Turbo option.... I used TMonitor and ran it while I was using some other programs and it showed that all 4 cores were up over 3.3XX. I guess I have to live with the default 2.7GHz or the OC'ed 3.3GHz.
Yes, Turbo Mode is pretty cool. Sorta like an "selective core OC on demand" that works by default (even when not conventionally OCed). There is lots of info on the net about it (just Google it) and over at Intel.com.
Also, you might like this (I run it on all my machines):
