I have a Gigabyte GA-H61MA-D3V rev2.0 motherboard and an i5-3470 CPU. The board keeps restarting every few seconds. The CPU barely gets warm for that short period of time. (pulsating) However the board work fine with a G530 CPU. It has the latest BIOS flashed. F7c I've measured the tiny caps on the underside of both CPU's. The i5 measures very low, 0.8-1 Ohms while the other I get around 30 Ohms. I need some help if somebody still has this CPU (i5-3470) and could take some resistance measurements. I am very curious if these very low readings are normal or the CPU is demaged. Thank you. |

There is small chance resistance might be normal, although I'd expect resistance this low from something more modern. You really need a measurement of CPU based on the same die to be sure. --- Quote ---The i5 measures very low, 0.8-1 Ohms --- End quote --- BTW does this measurement include multimeter lead resistance or not? If it includes something like 0.4 ohm with leads shorted without measurement nulling/subtraction, then it's nearly certainly fried. |

Without leads resistance. Btw this is measured on VCC, but VCCAXG is also a few Ohms. According to this: https://www.gadget-manual.com/pinout-cpu/ |

What voltage is on VCC? I tried with 1V, but at 1A no capacitor gets hot. Without a thermal camera it is hopless. I thought maybe I get lucky and only a cap is partially shorted. |
