With older, 65nm processors, given the experience of others, I could set the CPU_VTT termination voltage to between 1.4 and 1.45V, but I didn't pay as much attention to "reported" voltage values.
Now, I've set the CPU_VTT voltage to 1.45V, but watched in increments to see how the reported or monitored value changed from the reported value under the "Auto" setting.
Reviewing Graysky's OC Guide, and noting the following article here at Anandtech:
Killing a QX9650 with high CPU_VTT settings
I felt pretty smug with "carefully" notching up the VTT voltage to 1.45V, when the changes and values shown in the BIOS monitor left it at 1.39V.
Anyone have any comments about this? The BIOS version for this 680i motherboard is a "sunset-of-the-lifecyle" revision, clearing up some Penryn-Wolfdale features that needed to be addressed. Early in the board's history, there were measured discrepancies in "set," "monitored" and "real measured" voltages --- and they'd been addressed as far as I can tell with BIOS revisions through last year.
