How I lowered my 3900x voltage WITHOUT a performance impact (Should work for whole lineup) Benchmark Alright, so I have seen a lot of people posting about what they have done to try to get better performance out of their Ryzen 3000 chips. Voltage initially was 1. Ryzen Master, CPUZ, HWMonitor, the voltages were consistently staying above 1. By supplying the processor with less voltage we’re reducing the amount of heat generated in use. e. Need to take that voltage down. 25-1. 4ghz all core 1. 2 on all-cores (encoding and stress testing that's the highest it hits on all-cores). The part of the chip that doesn't need that voltage gets a lower voltage. Chipset Core - 0. The Ryzen 9 3900X is a powerful and efficient CPU from AMD that boasts impressive stock frequencies and voltage levels. I know that upping the vddg voltage is a key part to this but 950 is not working. Zen 2 is best left at auto with PBO (or with a negative offset voltage), because that's how the folks at AMD with PhDs have designed to behave. 3V as the ideal spot. Should be a selection if offset-mode negative or positive and then an additional entry for the offset. 2 is totally safe. A good AIO Cooler like the Kraken X73 can do wonders with these CPUs. 6/4. 325 has been reported by AMD as a "Safe" but I cannot find this on any AMD articles or really any kind of review / overclock review. the base speed is said to be 3.
