Undervoltage too low?
Undervoltage too low?
Hello everyone,
I've begun adjusting the undervolting settings on an Athlon II X4 640 at stock speed from auto (around 1.40v) down to 1.18v and everything is stable so far. I haven't hit the lowest voltage yet because the changes are progressing slowly, but I'm worried about potentially harming the CPU, memory, or power supply. Should I continue?
I've also run tests with IntelBurnTest.
Temperatures remain below 50º C.
Performance is normal.
Thanks.
Under voltage isn't an issue for the CPU directly. The crashes usually stem from the CPU struggling to keep up and possibly corrupting data on the OS disk. You should be aware that undervolting can lead to crashes similar to overclocking without increasing the Vcore. Nothing is likely to get damaged, but system stability could be affected if you attempt to overclock.
When adjusting settings that might cause a crash, it's best to disable write caching on all disks in Device Manager first for added data safety.
Hi, thanks for the question. I'm curious about why some people believe undervolting the CPU might harm components. Have you checked stability by running games or doing regular tasks?

Hello and welcome to Tom's forum.
What concerns you about undervolting the CPU causing damage? Have you checked stability with games or regular everyday tasks?
I was worried. I don’t play games, but normal daily use seems fine. Thanks.
The Tester explained that under voltage isn't an issue for the CPU itself. The main risks come from the CPU failing to keep up and possibly corrupting data on the OS disk. Undervolting might lead to crashes similar to overclocking without increasing Vcore. Nothing should be damaged, though system stability could be affected if you're trying to overclock. When adjusting settings that could cause a crash, it's best to disable write caching in the device manager for extra safety.
