it says LLC is disabled I think. Its the first line in that screenshot

For overclocking purposes should i assume that it never goes above what is set in the BIOS, or should i assume that it actually goes as high as CPU-Z says?

You should assume it is whatever your multimeter says your voltage is.

The screenshot of CPU-z and Intel Burn Test looks like the test is running. If you see your vcore go up when the test is running then it would appear that Gigabyte is forcing Load-Line Calibration on despite what you set, in which case it is a bios issue and a sucky board.

The difference between your target 1.35V and the actual 1.416V is 4.8% variance... and that assumes that the 1.416 measurement of actual voltage is accurate. You would need a calibrated $250 DMM and a good test point to verify those numbers.

If your actual voltage goes higher than your target voltage, I would recommend lowering your target so that the actual comes in where you want it to be. E.g. if you're trying to stay at 1.35v actual voltage, you might need to set the BIOS to 1.325V or so. Trial and error!

My experience is that the bios is not too accurate, especially when it comes to temperature. Trust the multimeter instead wink.gif
