AMD AMD Ryzen Threadripper 3990X Castle Peak 2.9GHz 64-Core sTRX4 Boxed Processor

AMD 3990X Threadripper

Announced at CES 2020, AMD's 3990X Threadripper processor is a huge leap forward in processing power. The 3990X is designed for creators who need the best rendering performance to enhance productivity and work flow. With 64 cores and 128 threads, you'll be able to run video encoding or rendering applications at blistering speeds and eliminate timeline lag.

Recommended CPU Cooling Solutions

While you can run an air cooler, such as the Noctua NH-D15S CPU Cooler, you may want to consider an All-In-One (AIO) water cooling solution with a 360mm radiator to maximize performance under heavy loads and minimize noise. We recommend the following for ease of maintenance and performance:

• Corsair Hydro H150i Pro 360mm RGB Water Cooling Kit
• EVGA CLC 360 360mm RGB Water Cooling Kit
• NZXT Kraken X72 360mm RGB Water Cooling Kit
• Corsair Hydro XC9 RGB CPU Water Block

Recommended RAM

For maximum performance, you need to feed all of those cores with a minimum of 64GB of fast RAM. Micro Center recommends the following kits:

• Corsair Vengeance RGB Pro 128GB (4 x 32GB) DDR4-3200 Quad Channel Memory Kit
• G.Skill Trident Z Neo Series RGB 128GB (4 x 32GB) DDR4-3200 Quad Channel Memory Kit
• G.Skill Trident Z Neo Series RGB 64GB (2 x 32GB) DDR4-3200 Dual Channel Memory Kit
• Other compatible options

Recommended Motherboards

• ASUS TRX40 ROG Zenith II Extreme Alpha AMD sTRX4 EATX Motherboard
• MSI TRX40 Creator AMD sTRX4 EATX Motherboard
• Gigabyte TRX40 AORUS XTREME AMD sTRX4 ATX Motherboard
• Other compatible options may require a BIOS update for optimal performance
