Overclocking Results

CPU Overclocking

AMD's Threadripper platform is quite interesting as AMD stated the top 5% of Zen dies become Threadripper CPUs. That is a big deal, as that would also mean the CPU should overclock quite high, or at least consistently high.

My best overclock on the X370 platform was 4GHz with 3200MHz memory speeds after months of BIOS updates, so I will aim for the same here. Most people get limited around 4.1GHz, and I know my 1950X can't do 4.1GHz stable on all cores without tons of voltage or better cooling.

All I had to do to hit 3200MHz in quad channel was to enable XMP in the UEFI. To overclock the core, I change overclock mode to manual, and then a frequency input box and voltage input box show up.

It might be confusing as to where you input the CPU voltage, as there are actually two places, but I just used the voltage input box under the CPU frequency instead of the voltage under the voltage section of the overclocking menu. I also did not have to use LLC, but it's there in case you need to tune it.

The system was stable; the only limitation is cooling.
