Overclocking Your Ryzen Threadripper processor


Overclocking and tweaking then. Always invest in good hardware by the way (MOBO/PSU/Memory/Cooling), the cheaper motherboards often are not well tuned for enthusiast overclocking. Also get yourself a good power supply and proper processor cooling. Overclocking with a more core processor (it doesn't matter if that is Intel or AMD) is often far more difficult than you expect it to be. 


For the Ryzen Threadripper reference review round we'll use nothing more than a Corsair Hydro 105 cooler.

Overclocking multi and many cores on a high clock frequency with Threadripper is a relatively okay to do job, and can be managed relatively easily from the BIOS. You can also use AMD's software tool of course.

Everything Ryzen, and that includes the series 3, 5, 7 and now 12 and 16-core Threadripper processors reach roughly the same values as the 8-core Ryzen 7 series. This makes sense as the reality is that the processor die is the same, the 8-core die part with two CCXes, however, for Threadripper is binned, they only use the top 2% dies. That means lower voltages. 

During our measurements, by trial and error we found that at 1.325~1.350 Volts you will end up at roughly 4.0 GHz. You could apply a fixed voltage, but we do recommend a voltage offset (start with +200Mv).

BIOS Overclocking

The Guru3D reader-base overclocks mostly from the BIOS to try and find the maximum stable limit. The generic overclock procedure for multiplier based overclocking is as follows:

  • Leave base clock (bus) for what it is right now (100 MHz)
  • Set the per core multiplier at a maximum of your liking:
  • Example 1: 100MHz x 40 = 4000 MHz
  • Example 2: 125MHz x 32 = 4000 MHz
  • Increase CPU voltage; though AUTO works fine on many motherboards you can do it manually as well. Start at 1.325 volts (or voltage offset (start with +200Mv)) and work your way upwards into a state of equilibrium in perf and cooling temps.
  • Make sure your processor is properly cooled as adding voltage = more heat
  • Save and Exit BIOS / uEFI



The simple three step overclock:

  1. Enable 4000 MHz (40 Multiplier)
  2. Apply 1.350V to the CPU (increase offsets to +240)
  3. Enable XMP/ DOCP on our memory kit (ours does 3200 MHz CL14)

Ryzen Threadripper likes fast memory, so with this quad-channel setup we really can recommend higher frequency memory like the 2933 and 3200 MHz kits used. Save and exit, and you will boot with all your cores tweaked to 4.0 GHz into Windows. 


Here is an example of the Ryzen Threadripper 1950X at 4000 MHz @ all cores. Here the LCS cooler seems to run fine in the ~80 Degrees C range overclocked (again that is 16 cores). AMD claims the Tdie score is the actual score, so you can deduct 27 Degrees C off that temperature.

Now, we tried 4.1 GHz on all cores, that booted as well / and thus worked but required significantly more Voltage (V1.40+) on the processor, and that also means more heat and power consumption. We settled at that all familiar 4.0 GHz on all 16 cores. Memory wise we had 3200 MHz CL14 stable. We inserted all OC benchmarks results throughout the article for you to look at (as you probably have noticed). And that is also testimony to the stability of this tweak.

Power Consumption

Adding extra voltage to the CPU for the OC also has an adverse effect on the overall energy consumption. Below, the power consumption for the whole PC measured at the wall socket side including a GeForce GTX 1080. Blue is default, black is overclocked.
