'''Ryzen Threadripper 1900X''' is a {{arch|64}} [[octa-core]] high-performance [[x86]] desktop [[microprocessor]] introduced by [[AMD]] in mid-[[2017]]. The 1900X, which is based on their {{amd|Zen|Zen microarchitecture|l=arch}}, is fabricated on a [[14 nm process]]. This processor operates at a base frequency of 3.8 GHz with a [[TDP]] of 180 W and a {{amd|Precision Boost|boost}} frequency of up to 4 GHz. This MPU supports up to 2 TiB of quad-channel DDR4-2666 memory.

This processor supports up to 512 GiB per memory channel for a total of 2 TiB.
+
This CPU supports 8 DIMMs of rates 1,333 MT/s - 3,200 MT/s (UDIMM/SODIMM).  Note that despite AMD's support for memory rates of 3,200 MT/s and possibly higher, rates beyond 2666 MT/s exceeds the [[JEDEC]] specification and is thus considered overclocking which voids AMD product warranty and likely any vendor or retailer warranties as well.
