Short Answer: Building a DeskMini B660 Mini PC involves selecting compatible components, assembling hardware, configuring BIOS settings, installing an OS, and optimizing performance. This guide simplifies the process for first-time builders with actionable steps and expert tips to avoid common pitfalls while maximizing efficiency in compact builds.
How to Choose the Best ASRock DeskMini B660 Mini PC
What Components Are Needed for a DeskMini B660 Build?
The DeskMini B660 supports 12th/13th Gen Intel CPUs, DDR4 RAM (up to 3200MHz), and M.2 NVMe SSDs. Essential components include a compatible processor (e.g., Core i5-12400), 16GB DDR4 RAM (dual-channel recommended), a 1TB NVMe SSD for storage, and a 19V DC power adapter. Avoid full-sized GPUs as the system relies on integrated Intel UHD graphics.
| Component Type | Recommended Model | Notes |
|---|---|---|
| RAM | Crucial CT2K16G4SFRA32A | Low-profile design for clearance |
| SSD | Samsung 980 Pro 1TB | PCIe 4.0 x4 interface |
When selecting memory modules, prioritize 1.2V JEDEC-standard DDR4 sticks to ensure compatibility. The chassis supports only single-slot SO-DIMM configurations, making dual-channel 32GB kits ideal for content creation workloads. For storage, utilize both M.2 slots (2280 and 2242) in RAID 0 configurations if requiring sequential read speeds above 7GB/s.
How to Install Hardware in the DeskMini B660 Chassis?
Begin by unscrewing the chassis lid. Install the CPU into the LGA1700 socket, aligning the golden triangle. Attach the bundled low-profile cooler using the pre-applied thermal paste. Insert RAM sticks into the SO-DIMM slots, applying even pressure. Mount the NVMe SSD on the M.2 slot (PCIe 4.0 recommended). Reassemble the case, ensuring all cables are routed neatly to avoid airflow obstruction.
Use anti-static wrist straps when handling components to prevent electrostatic discharge damage. The chassis features tool-less installation for drives but requires a Phillips #0 screwdriver for motherboard components. When mounting the CPU cooler, apply diagonal pressure gradually – the retention mechanism requires 15-20lb of force for proper contact. For optimal thermal performance, ensure the SSD’s thermal pad makes full contact with the chassis’ aluminum heatspreader.
Which BIOS Settings Optimize DeskMini B660 Performance?
Access BIOS by pressing Delete during boot. Enable XMP Profile 1 for RAM overclocking. Set “Power Saving Mode” to “Disabled” for maximum performance. Adjust “CPU Core Voltage” to “Adaptive” for thermal efficiency. Disable unused ports (e.g., legacy SATA) to reduce boot times. Update BIOS to version 1.7 or newer via USB flashback for improved memory compatibility and power management.
How to Install Windows 11 on the DeskMini B660?
Create a bootable USB using Microsoft’s Media Creation Tool. In BIOS, disable Secure Boot and enable UEFI mode. Allocate 100GB for the OS partition during installation. Install Intel Chipset Drivers and ME firmware from ASRock’s website post-installation. Enable Core Isolation and Memory Integrity in Windows Security for enhanced protection against firmware attacks.
Why Does DeskMini B660 Overheat and How to Prevent It?
Thermal throttling occurs due to the 47mm CPU cooler height limit. Replace the stock cooler with a Noctua NH-L9i-17xx for 8°C lower temps. Use high-conductivity thermal paste like Arctic MX-6. Set a custom fan curve in BIOS (70% speed at 60°C). Position the chassis vertically for improved convection. Avoid continuous 100% CPU loads exceeding 30 minutes.
| Cooling Solution | Noise Level | Max TDP Supported |
|---|---|---|
| Stock Cooler | 42 dB(A) | 65W |
| Noctua NH-L9i | 23 dB(A) | 95W |
Implementing a negative voltage offset (-50mV to -100mV) through BIOS significantly reduces heat output without sacrificing performance. Third-party testing shows the i5-12600K maintains 4.1GHz all-core clocks under sustained load with this adjustment. For advanced users, liquid metal thermal compounds can yield 3-5°C improvements but require careful application to prevent short circuits.
“The DeskMini B660’s 1.9L footprint challenges builders to balance performance and thermals. Our stress tests show the i7-12700 maintains 4.5GHz all-core boost with a 65W PL1 setting. For silent operation, pair with a PicoPSU-160-XT and 19V GaN adapter. Remember: BIOS updates resolve 80% of POST issues in compact builds.”

Conclusion
The DeskMini B660 offers unparalleled customization in ultra-compact form factors. By following this guide, users can achieve desktop-grade performance while maintaining thermal stability. Regular BIOS updates and component monitoring through tools like HWiNFO64 ensure long-term reliability. This system proves that 6-core productivity and 4K media playback coexist in sub-2-liter designs when configured precisely.
FAQs
- Can DeskMini B660 Support Dual 4K Monitors?
- Yes. The HDMI 2.0 and DisplayPort 1.4 outputs support dual 4K@60Hz displays using Intel UHD 730/770 graphics. Enable Multi-Stream Transport (MST) in BIOS for daisy-chained monitors.
- Is Thunderbolt 4 Available on DeskMini B660?
- No. The B660 chipset lacks Thunderbolt support. Use the USB 3.2 Gen2x2 Type-C port (20Gbps) for external storage. ASRock’s optional Thunderbolt add-on cards aren’t compatible due to space constraints.
- What’s the Maximum RAM Capacity?
- 64GB (2x32GB) DDR4-3200 via SO-DIMM slots. Crucial CT2K32G4SFD832A modules are validated. Higher frequencies require manual timings and increased SA voltage (1.35V max).
