Good find. You're right, CPU-Z must be reading the "uncore" as QPI. My actual QPI must be 6426, as shown in the bios. That seems pretty damn fast.
This is all made more confusing by the fact that my BIOS doesn't show the actual multipliers.
So, like the article says, my uncore (CPU-Z's "QPI") is twice my DIMM speed - 3213/1606.5. Then it gets weird, because this uncore speed also happens to be exactly half the BIOS set actual QPI (no CPU-Z reading for this) of 6426.
If I'm understanding this correctly, the "uncore" is basically the fequency at which the memory control communicates with the memory. Is that how it sounds to you? And the QPI connects the processor to the chipset... what chipset? The Southbridge? Who cares? Does the Southbridge even do anything important on these H55 boards?
So it's the uncore that needs to be boosted for better overall performance, not the QPI? In that case it's pretty convient that CPU-Z is actually showing the uncore rather than the QPI.
EDIT: QPI might actually matter for you because the P55 boards actually have a regular style chipset. My board only has a Southbridge and the PCIe control is integrated into the i3... although it's integrated into yours too... so does you rig use the controller on the i3 or the one on the P55 chip...
This is getting confusing quickly.
Ok, did some more reading. i3 has the PCIe control and the memory control on CHIP, not on DIE. So the QPI for Clarkdale is internal with the other side of the chip, whereas the QPI for Lynnfield is external with the Northbridge. QPI still matters for Clarkdale because it's the speed at which the cores in the die communicate with the on-chip (but not on die) memory and PCIe controllers.
