ASRock B660M Steel Legend Motherboard Review – Design and Functionality

The motherboard comes with all the benefits and essentials present in the Steel Legend series products. That means you can enjoy its rock-solid durability and excellent camo design aesthetics. ASRock created the board with mainstream and daily users in mind, giving them the reliability and stable performance they need. 

But what makes it click? It gives you all this at a decent price. 

We focused on the design aspects for this ASRock B660M Steel Legend motherboard review. Here, we saw it sporting a military-themed PCB with grey & white heatsinks. This design inclusion makes it appear similar to the B560 Steel Legend.

It also has a few big splashes of RGB lights along its right side and the chipset heatsink. Keep in mind that it appears very bright, a bit too bright even.

This motherboard has a smaller micro-ATX PCB and comes with fewer PCIe slots compared to the ATX versions. It comes with a full-length PCIe 5.0 x16 slot and two PCIe 3.0 x1 slots. Then, there are also two PCIe 4.0 x4 M.2 slots available. 

There are other storage options available, and these are six SATA ports where four are powered by a specific chipset. The latter supports RAID 0, 1, 5, and 10 arrays. Then, the other two are powered by an ASMedia ASM-1061 SATA controller. 

Memory Slots on the ASRock B660M Steel Legend Motherboard

The motherboard also comes with four memory slots that support DDR4-5000 while having a capacity of up to 128GB. Its rear panel has four USB 3.2 G1 Type-A, as well as two USB 2.0 ports. Plus, there’s a Realtek RTL-8125BG 2.5 GbE controller and a Realtek ALC-897 HD audio codec.

The audio codec powers an S/PDIF optical output and five 3.5mm audio jacks. There’s even a PS/2 combo port and an HDMI 2.1 + DisplayPort 1.4 video output pairing available. Lastly, you’ll find a little BIOS Flashback button too. 

Overall, we consider the B660M chipset more than enough. It’s great for people who want an affordable board that supports 12th Gen Alder Lake processors. 

Key Features of the ASRock B660M Steel Legend Motherboard

We’ll discuss this product’s key features to find out what makes it better than other motherboards on the market.

True Legend – Tough and Durable Design

ASRock’s Steel Legend series represents rock-solid durability combined with great aesthetics. Products under this line are built with demanding specs and features to address the needs of daily users and enthusiasts. It has powerful materials and components that ensure stability and reliability.

Integrated Dr.MOS Solution

The Dr.MOS power stage solution integrated into the B660M Steel Legend is optimised for synchronous buck-step down voltage. Unlike conventional discrete MOSFETs, Dr.MOS works smartly by delivering a higher current for each phase. This results in better thermal results and enhanced performance.

9 Power Phase Design

The B660M Steel Legend features sturdy components, allowing for smooth power delivery to the processor. With that, the motherboard offers improved performance that is suitable for gaming. 

When we tested the product for our ASRock B660M Steel Legend motherboard review, our PC performed seamlessly while playing.

6-Layer PCB of the ASRock B660M Steel Legend Motherboard

With the 6-layer PCB, signal traces will be stable and power shapes will offer higher efficiency while keeping temperatures low. Because of this, the motherboard can support the newest memory modules. This is ideal for memory overclocking and extreme memory performance. 

Surface-Mount Tech (SMT) PCIe 5.0

Compared to traditional DIP style PCIe slots, the SMT type maximises stability and improved signal flow at high speed. This feature is essential to fully support the lightning speed of PCIe 5.0 which can deliver 128 GBps bandwidth. With PCIe 5.0, this motherboard can unleash the full potential of upcoming high-end graphics cards.

Nichicon 12K Black Caps for Longer Lifespan

The Nichicon 12K Black Caps are 100% Japan-made conductive polymer capacitors with at least 12,000 hours of lifespan. This is 20% longer than its counterparts which are used on other high-end motherboards.

Powerful Algorithms – Enhanced Communication Quality

Powerful Algorithms ensure a constant vocal level and noise-free conversations regardless of your mic’s distance. The Nahimic audio engine dynamically removes interference noise, clears the audio, removes interference noise, and reduces voice variation. As a result, there will be better comprehension and communication.

Polychrome RGB to Customise the ASRock B660M Steel Legend Motherboard

The B660M Steel Legend comes with built-in RGB illumination, onboard RGB headers, and an ARGB header. These allow you to connect compatible LED devices like coolers, CPU fans, chassis, strips, and more. You can also synchronise these peripherals and components across Polychrome RGB Sync-certified products for unique lighting.

High Speed M.2 Solution

This motherboard can accommodate multiple M.2 storage devices and one of these can support PCIe 4.0 M.2. With that, it can perform two times faster than the previous 3rd generation, making data transfer faster than ever.

ECC RAM Support for Data Failure Prevention

ECC RAM support prevents major data failure concerns like data transcription issues, file corruption, security vulnerability, and data loss. If these issues occur, it’s better managed with ECC.

Meet Demands with Dragon 2.5 Gb/s LAN’s Maximum Networking Performance

The smart 2.5Gb/s LAN platform is designed for maximum networking performance. It’s to meet the demanding requirements of home networking, content creation, high-quality media streaming, and online gaming. It increases networking performance up to 2.5X the bandwidth compared to the traditional gigabit Ethernet.

Dragon 2.5 Gb/s LAN lets you enjoy the faster, reliable, and uncompromised connectivity experience.

Base Frequency Boost Technology

This feature allows utilising increased TDP to take advantage of the base frequency boost with the processors’ potential power. This is with non-K series CPUs and selected ASRock motherboards under the 600 series.

Note that the boost frequency still depends on the cooling system you used on your rig.

Nahimic Audio for an Engaging Listening Experience

Headphones, headset, internal/external speakers – no matter what you use, you’ll enjoy your audio better than ever with Nahimic Audio. This feature offers rich, vibrant, and detailed audio to make your listening experience more engaging.

The Best Gaming Experience with the ASRock B660M Steel Legend Motherboard
