I had to replace a motherboard over the weekend. My GA-Z87X Gaming 7 developed a short. There was a loud pop Friday night. No more run. No more boot. Saturday I went to MC and replaced it with the same board. The i7 4790K is the same on the new board as the old.

I went to replicate my heatsink testing runs a 4GHz (I'm testing a lower capacity heatsink). Linpack w/o AVX had an auto Vcore of 1.032v displayed on the old board, 1.202v displayed on the new board. Linpack w/AVX had a Vcore of 1.056v on the old board, 1.044v on the new board.

I suspect I am getting the same VID, so the different Vcore readings -- I think -- are due to manufacturing variations in the motherboards, and do not represent actual Vcore differences. They are with the same CPU, after all.

So, the time has come for me to abandon software-read Vcores. Since there are measuring points on the motherboard. I can directly measure a number of Voltages, including Vcore.

Problem: my 30-year-old Radio Shark Voltage multimeter is analog. I need a digital multimeter. One that will measure out to 3 decimal places between 1.0 and 1.4 Volts. Can such a thing be had for under $100? Or should I live with the new board and forget it?
