Hi jezzarino
Thanks for your respons/explanation about VCC and VID volt.
This may be why many users/gamers believe that they are/can run there Intel oc cpu with 4.5-4.7 GHz at about 1.30-1.35 volt, because they are reading/looking at the VID volt only.
The 1.42 VCC volt Intel's own oc assist is using at 4.60GHz, is not enough for 100% stable gaming like Battlefield3.
Since the 3930K was released, AMD has push/optimized there GPU driver for higher fps in games, this fps increase does not come out of no where. The latest AMD GPU drivers are pushing/seeking more power out of the CPU.
When users/gamers wants to oc, it is recommended to run some stress test like IntelBurnTest, to ensure that the CPU gets the VCC it needs.
At 4.60 GHz my Intel 3930K needs 1.47 VCC volt.
At 4.70 GHz it needs 1.485 VCC volt.
BTW, I am very happy with my Intel 3930K and the Intel DX79SI, only sad thing is that Intel will stop producing their own motherboards.
Intel should reconsider and continue to produce their own motherboards for the Extreme series, like the DX79SI and DX79SR in the future too, and only stop the mainstream boards.
