Hi. This is a follow up question to a discussion I started here some days ago regarding the i7 3930K CPU and safe temps.
I'm using an Asus P9X79 Pro motherboard and when I enable XMP on my DDR3 1600 GSkill Sniper RAM, the mobo implements maximum turbo for any core usage. As such, the board automatically fixes vcore at around 1.32v even at idle or just browsing the net. This is built-in feature of the board. It disables power savings and idle states in the process. My PC runs fast on these settings, there is no doubt about it. But I have seen my vcore go up to around 1.38v playing games. I am now starting to worry that the inordinately high vcore may damage my CPU over the long run.
Do I have cause to worry?
Since you are running the RAM in XMP configuration, then the behavior that you are reporting (up to 3.8 volts) is expected since the XMP will “Over-clock” the whole system, not only the RAM, and since XMP is to be considered as tested configuration, then there should not be any issue.
