Core voltage specifications for Ryzen 3rd generation processors
He emphasizes issues constantly using phrases like "you have to" and "otherwise it won't run properly," suggesting significant risks that aren't present. Every Ryzen 3rd generation setting involves lowering voltage for a given frequency, which typically leads to performance decline without a crash. This highlights the need to test each setting with benchmarks like Cinebench R20 and 3DMark Fire Strike for stability. If standard voltages feel unsafe, you can safely undervolt and underclock the CPU without restrictions. Quiet mode merely conserves power, turning off efficiency instead of protecting hardware. Any software issues also matter; since Zen 2's clock modulation is faster, Ryzen Master helps manage timing accurately. The only flaw is that the CPU operates at full speed and voltage in the BIOS, which AMD has made very aggressive for single-threaded tasks—likely to counter the "single core performance suck" stereotype.
Intel wished made those changes. They’d probably be offering 5.3ghz i9 models, right? But back then, single-core voltages were way higher. I believe they’re designed to be reliable, lasting at least three years. However, PBO tends to get quite aggressive with single-core voltages. I noticed that at 3600 RPM, a 65W draw runs at full load across all cores, then PBO reduces it to 65W for just one core. That’s quite surprising.
I don’t care much about stock prices, but since Anthony suggested a 1.35 V core, I’m curious if it actually hurts single-core performance or just wastes power because they can’t lower the voltage on lighter loads.
It could affect performance or not. The result varies based on the CPU you have (different chip designs). Anthony seems cautious because suggesting high voltages without more info is potentially dangerous.
In short, the recommended max voltage is around 1.35V, mainly for safety and based on observations about silicon wear. Going beyond that risks damage unless you have very specific hardware settings. High currents matter more than just pushing voltage, especially with thermal limits. Voltage readings can be misleading because some cores stay high even when idle due to software limitations. Performance depends on many factors like board, BIOS, and chip variations.
If I pin it at 1.35V it can still lower the voltage to conserve energy and reduce heat during idle time.
The processor will automatically reduce its power consumption (through Ryzen Master) when idle.
