AUDIO BOOST 5: Isolated audio with a high-quality audio processor & amp for the most immersive gaming experience A few things to note. Any temperature below 80c is to be considered very cool, VRM temps only start to become a concern when they exceed 90c, and even then there's still 10-20c worth of headroom before most boards will thermal throttle. Below 80c is very safe and will never present an issue, so all X670 boards are well within safe limits.

Extreme Power Design: 24+2+1 phases power design with 105A Smart Power Stage and dual CPU power connectors are ready to unleash the maximum performance. An expensive motherboard but worth it if you will use the extra features. By far the biggest draw for this board (as another reviewer pointed out) is that is does not take away from the GPU lanes if all NVME/Sata slots are populated. This is massive compared to most other AM5 boards if you hold a lot of data/media. I originally had a Strix motherboard but felt like I could never use the 4th slot, which kind of defeated the point of having it.

LAN with LAN Manager, BlueTooth 5.2, and AMD Wi-Fi 6E Solution: Upgraded network solution for professional and multimedia use; delivers a secure, stable, and fast network connection And well, the good news is you don't have to worry about VRM thermals with X670 boards, not even a little. In the past, we've seen boards that should perform well fail miserably in this testing, but that's not the case here...

Enhanced Power Design: 18+2+1 Duet Rail Power System, Dual 8-pin CPU power connectors, Core Boost, Memory BoostFor the stress test, we're using Cinebench R23 looped for an hour, at which point we're reporting the maximum PCB temperature recorded using the k-type thermocouples. For recording temperatures we're using a digital thermometer with K-Type thermocouples and we'll be reporting the peak rear PCB temperature. Finally, we're not reporting Delta-T over Ambient, instead I maintain a room temperature of 21 degrees and to ensure a consistent ambient temperature a thermocouple is positioned next to the test system. It's an extreme motherboard as well, the 16 teamed 110A powerstage vcore VRM is no joke, there's two PCIe 5.0 M.2 slots, USB4 support, loads of USB ports, onboard buttons, debug LED codes, 2.5 Gbit LAN and WiFi 6, it's an impressive but also ultra expensive mATX motherboard. Premium Thermal Solution: Aluminum cover, MOSFET thermal pads rated for 7W/mK, additional choke thermal pads and 3x M.2 Shield Frozr are built for high performance system and non-stop gaming experience Lightning Fast Game Experience: PCIe 4.0, Triple Lightning Gen4 x4 M.2 with M.2 Shield Frozr, StoreMI, AMD Turbo USB 3.2 Gen2.

Delivers a secure, stable and fast network connection Premium Thermal Module: Wavy fin design, Direct Touch Cross Heat-pipe, MOSFET Baseplate, 7W/mK thermal pads, Double-Sided M.2 Shield Frozr and Frozr AI software ensure the utmost performance with low temperature. Lightning Fast Game experience: PCIe 5.0 slots, Lightning Gen 5 x4 M.2, Front USB 3.2 Gen 2x2 20G with 60W USB Power Delivery.Memory Support DDR5 6600+(OC)/6400(OC)/ 6200(OC)/6000(OC)/ 5800(OC)/ 5600(OC)/ 5400(OC)/ 5200(OC)/ 5000(OC)/ 4800(JEDEC) MHz For some reason Gigabyte spent their PCIe 5.0 budget on the M.2 drives, limiting the PCIe slot support to a single x16 slot. So while we guess four PCIe 5.0 M.2 slots is nice, we'd rather have the flexibility of having more PCIe slots. Still, if you were to use PCIe 5.0 devices this configuration would make the most sense, as both delivers would receive x8 PCIe 5.0 bandwidth which is 32 GB/s. In comparison the Asus ROG Strix X670E-F Gaming connects its secondary PCIe x16 slot chipset, which is a lot cheaper to wire in, but does limit you to PCIe 4.0 x4 bandwidth (8 GB/s).

You also get USB4 support, 10 USB ports on the I/O panel, high quality external audio, two M.2 ports, 2.5 Gbit LAN and WiFi 6E, so it's a super well equipped ITX motherboard, but of course it's not exactly cheap. Of course, it is an X670 Extreme board so you get PCIe 5.0 for the primary PCIe slot, which is nice, there's also a second PCIe 5.0 M.2 slot and the VRM has been upgraded with 105A powerstages from the 60A models used by the Elite AX but really that's going to be of benefit for very few people. The motherboard comes equipped with three PCI-E x16 slots, of which two are PCIe 5.0, with the remainder being PCIe 4.0. The inclusion of MSI Steel Armor soldering helps with overall rigidity when mounting heavy triple fan graphics cards.

These are great news to share: there are no bad X670/X670E motherboards. Surely prices might be a bit hard to swallow, but there are no duds, and that's a rare thing when reviewing an entire motherboard series. We hope you found this useful and expect a similar piece covering B650 motherboards. Shopping Shortcuts:
