Amazing!Īnd the final score is 5,942 points! Oh wait, that is way lower than the stock score if 7,105 that I got with stock ‘Auto’ voltage settings. I left HWiNFO64 open to monitor speeds and it was showing that the 3900X was running at 4.2GHz on all 12 cores during the benchmark run. The system booted right up with the Vcore manually set to 1.10V and Cinebench R20 was running like a champ.
I’ll be running Cinebench R20 with four CPU Vcore settings (AUTO, 1.2V, 1.1V, 1.0V) to show you what happens to performance when you drop the voltage on this Zen 2 processor. Most those reporting on running 1V flat on the Ryzen 9 3900X are just showing thermal performance and not benchmark numbers. The Ryzen 9 3900X CPU just happens to still be in the Gigabyte AORUS X570 Master motherboard, so I restarted our system and went straight to the CPU Vcore setting in UEFI F5g and took it off ‘AUTO’ and dropped it down manually to 1.20V, 1.10V and 1.00V to see what would happen. That sounds pretty damn impressive and I just had to give it a try here to see if that is possible and what that means for performance. I noticed a number of sites and channels are reporting that the AMD Ryzen 9 3900X 12-core, 24-thread processor can be run at full clock speeds with just 1.00V on the CPU VCore.
