The high CPU voltage from XMP is within normal limits.
The high CPU voltage from XMP is within normal limits.
Hello everyone, I recently upgraded my PC. I installed an Intel Core i7-14700K on a Z790 Aorus Elite AX with BIOS version FH (checksum: 7B85) and 2x16GB Corsair Dominator Platinum RGB DDR5-5600 CL36. After setting up Windows, I turned on XMP in the BIOS and observed a CPU voltage range of roughly 1.3V to 1.35V with occasional spikes reaching up to 1.43V when using my machine and monitoring with HWiNFO. During a game session lasting about 20 minutes, HWiNFO recorded an average of around 1.35V across all cores. Is this acceptable? Or is the voltage too high? I’m looking for advice. Thank you in advance, Keju.
XMP doesn't influence CPU core voltage, which means it isn't the root issue. Instead, it relates to the VID voltage—what the CPU expects—not what it actually gets. You should check lower levels to observe the real CPU voltage. This can vary depending on the specific board and its die sensing configuration (often labeled as VCC IN, but may differ). Typically, the difference isn't huge, though I've seen cases where VID exceeds VCC IN by more than 100mV. Regardless, 1.45V is generally acceptable for 13th/14th generation chips, so as long as temperatures are stable, voltage concerns shouldn't be major.
Typically the problem stems from excessive voltage on the chip. Adjusting a -0.05v offset in BIOS can help, lowering power use and heat if needed. Models around 14700 and 14900 often face overheating under heavy all-core workloads without proper power management or strong cooling solutions.
