We noticed our 4K video exports finished about 40% faster compared to the previous generation Ryzen 9 3950X.
Temperature management requires attention with this powerful chip. During our stress tests, temperatures reached the mid-80s Celsius with our 360mm AIO liquid cooler.
As AMD recommends, don’t skimp on cooling for this processor. The investment in proper cooling will allow the chip to maintain its high boost clocks consistently.
The PCIe 4.0 support pairs perfectly with the latest NVMe drives and GPUs. We measured sequential read speeds over 7000MB/s on our Gen4 SSD, something impossible with older platforms. This makes large file transfers lightning fast for work projects.
Buying Guide
Choosing the right motherboard for your Ryzen 9 3950X can be tricky. We’ll help you understand what to look for when making your purchase.
Socket Compatibility
The most important feature is the socket type. The Ryzen 9 3950X requires an AM4 socket. Without this, your CPU won’t fit at all.
Chipset Options
Not all AM4 motherboards work well with the 3950X. X570 offers the best performance, while B550 provides good value.
The X570 chipset provides PCIe 4.0 support across all lanes, while B550 limits it to the primary slots.
VRM Quality
VRM (Voltage Regulator Module) quality is crucial for the power-hungry 3950X. Look for boards with robust VRM cooling and at least 12 power phases.
Good VRM design prevents throttling under heavy loads and ensures stability during overclocking.
Memory Support
The 3950X performs best with fast RAM. Look for motherboards supporting:
| Feature | Minimum | Recommended |
| [Memory Speed](https://bytebitebit.com/ram/best-3200-mhz-ram/) | 3200MHz | 3600MHz |
| Memory Slots | 2 DIMM | 4 DIMM |
| Max Capacity | 64GB | 128GB |
Expansion Options
Check for sufficient PCIe slots, M.2 slots, and SATA ports. With a high-end CPU like the 3950X, you’ll likely need room for multiple components.
We recommend at least two M.2 slots for NVMe drives and six SATA ports for traditional storage.
Connectivity Features
Look for boards with plenty of USB ports, including USB 3.2 Gen 2.
WiFi 6 and 2.5Gb Ethernet are nice extras for future-proofing your system.
