I recently got a ASRock 990FX Extreme4 motherboard and was having a lot of problems getting it up to clock speeds at similar voltages to what I had on my old Gigabyte 970 mobo.
I usually use CoreTemp to check my voltage when stress-testing, but I then tried CPU-Z and the ASRock Tuning utility and found that the actual system voltage appears to be 0.150volts less than what I have set it at in the bios and what CoreTemp displays. I triple checked the bios to make sure my vcore was set at 1.375v for a 4.1ghz overclock, but it only appears to be at 1.250v.
Does anyone know why this is happening or how to fix it?
Board readings are too inaccurate from program to program. Go by with what your BIOS has it set to but all readings done through board sensors are inaccurate so the only way to know for sure is take a multimeter and go straight to the power supply.
