Kougar | 24th December 2009 20:22 | Hm, I thought the uncore voltage could not be adjusted, but going by what you are saying if I adjust the "QPI voltage" (what Gigabyte unfortunately labels it) I am in fact changing the VTT voltage/uncore voltage? Or does changing the VTT not affect the uncore voltage as I had thought?
So Intel does mention a 1.65v limitation in the data sheets for LGA1156? Then to pose a question, what about the PCIe controllers, those would still be running at 1.5v, which is 0.4v higher than the VTT on the same die. Why would VTT/RAM voltage be an issue but PCIe wouldn't? IMC's just that sensitive? Anandtech mentioned something about amplitude, but was as much as I remember... |
