The CPU: AMD Ryzen 9 5900X AMD’s Ryzen 9 5900X is a 12-core, 24-thread processor with a 3.7 GHz base clock and a 4.8 GHz boost clock. It also features 64 Megabytes of L3 cache and supports DDR4 3200 MHz officially. AMD has set a 105W TDP rating for the CPU – indicating that it’ll require effective cooling to keep thermals in check.What is the power draw on the 5900x?
GamersNexus saw a peak power draw of 193 watts for the 5900X measuring draw off the EPS 12V rails, so I am assuming the discrepancy is the power draw of the motherboard, correct? Other benchmarks from other sources include total system draw which is not specific enough, in my opinion.Will a 5900x overclock work on a 5800x?
But with a few tweaks and conditions. All Ryzen processors have different boost clocks, so an overclock of 4.6 GHz might work on a 5900X but might not work on a 5800X. Please try lowering your CPU clock ratio slowly and run the Cinebench and Blender tests to get a stable overclock if the above settings aren’t doing the trick.How much power does the 5900x have in BIOS?
By default the 5900x is limited in bios to 142w package power. GamersNexus got 193w after overclocking and running blender. They got 133w with stock settings.
