Vcore and OC.

[thedocta45]

If at stock Vcore of 1.238v I am able to get the system running at a stable 2.6Ghz up from 2.4 is that any indication of how well the CPU will step if additional voltage is put into it?

IMO not enough information, is that as high as it will go stock ?


If you continued to attempt to raise the cpu speed at stock voltage and found the limit at stock it might. For instance if you were able to hit 3.0+ at stock it would be an indication of a very good core. If 2.6 up from 2.4 is as far as you can go on stock it is likely you will need a lot of Vcore to achevie a high overclock. Many other factors, cooling mainly, also contribute and at best it would only be a generalization, nothing is assured. The best thing to do is have a plan, test, take notes, benchmark and learn what your cpu is capable of without changing other factors. Then look at the other factors (memory timings , mch voltage, etc.) one at a time and once done and understanding how each affects performance and interact with the others, find the balance that gives stability and the performance you want.

It is fairly easy to crank in 1.40 Vcore and run 8 x 400 at stock memory timings and have good results. Tweaking everything to provide maximum performance at the minimum voltages, best memory timings and tweaked sub-timings for max memory bandwidth and a very high overclock is a different matter and requires a lot of work and time.

I thought stock voltage for an E6600 was 1.325v?

chips generally scale like this:

obviously some mhz and voltage differences for the intel, but more voltage has deminishing returns, and kills the proc faster. it's up to you to decide what voltage is optimal for your needs
