The I5 2500k isn't reaching 1.35v during Prime95 blend testing.
The I5 2500k isn't reaching 1.35v during Prime95 blend testing.
Chose to modify my 2500k for better relevance. Reached 4.5ghz using an overclocking guide. Began a Prime95 stress test; voltage is around 1.25 instead of the expected 1.35. Thought maybe something went wrong? Learned about LLC and realized it might be a problem. My motherboard is an ASRock Extreme 3 Gen 3.
Hi Minmay
LLC (Load-Line Calibration) When the CPU is working under load, its power consumption rises. This leads to a voltage drop that the motherboard automatically fixes by slightly raising the applied voltage. Some motherboards refer to this feature as Vdroop.
Typically, the Load-Line Calibration is an enable or disable option. During overclocking, it’s important to turn this feature on.
Settings in the BIOS can vary from minimal to extreme or based on percentages, depending on the overclock level.
Here’s a helpful guide on how to optimize your CPU to 4.5GHz:

P95 is an intense synthetic stress tester, likely intended for quick initial stability checks—about 10 minutes. Its method becomes more demanding with each cycle and should be closely watched alongside your temperatures.
P95 is not a genuine real-world CPU stress test; it pushes the processor to its absolute limit, similar to forcing a car engine to run at maximum speed.
For better stability results, consider other practical testers.
Have fun and feel free to share your outcomes.
