Hi. So I recently upgraded an old build's CPU from Athlon II X4 640 to FX 6300
The computer ran fine overclocked with the Athlon. Upon switching to the FX I noticed the CPU is throttling it's clock and voltage with stock settings. (Only when stress testing) With Turbo core on it throttles during normal use so I turned it off.
I put copper heatsinks on the VRM but same results.
I have an AIO water cooler with Kryonaut paste.
MSI 760GM-P23 (FX) Motherboard. Power Supply isn't much better it's a Thermaltake 430 But both ran fine and the power specs between the 2 processors are similar.
The Athlon ran at around 1.4v which is higher than FX is running at around 1.2. (Not sure if the core amount would make a difference since the Athlon was 4cores and the FX is 6cores.) I would think things run hotter.
See video below to see how and when the throttling begins. Notice the HUGE spike in "Core" temp in Speedfan and "Thermal Margin" on Overdrive. "Temp1" in Speedfan is the CPU's temp. It matches with BIOS temp, and is the only temp to rise when I turn off water pump.
Could the CPU be defective? I've only stressed it for about an hour and with throttling and all, no errors show.
