Asrock B150 Combo
The ultimate transition-era motherboard bridging DDR3 and DDR4 memory on the Intel LGA1151 platform.
Overview
How It Works
Select and Install One Memory Standard
Choose either DDR3/DDR3L or DDR4 memory modules. Place them in their respective color-coded slots, ensuring you never mix the two standards simultaneously to prevent hardware initialization errors.
Mount the CPU and Cooler
Insert an Intel LGA1151 processor (Skylake or Kaby Lake) into the socket. Apply thermal paste and secure your cooler, connecting its power lead to the designated CPU fan header.
Connect Storage and Expansion Cards
Plug your high-speed SSDs or HDDs into the SATA3 6.0 Gb/s ports or the dedicated SATA Express connector, then mount your graphics card into the primary steel-reinforced PCIe 3.0 x16 slot.
Configure UEFI BIOS and Boot
Power on the system, enter the Asrock EZ Mode UEFI, configure your SATA controller settings, set boot priorities, and let the integrated hardware detection optimize settings for your chosen RAM configuration.

Premium 50A Power Chokes
Effectively saturate up to three times better than traditional chokes, supplying enhanced and improved Vcore voltage to the motherboard.
Matte Black Heatsinks
Aluminum alloy VRM heatsinks dissipate heat passively from the MOSFETs, maintaining system cool-down during prolonged render tasks.
I/O Armor Shielding
A protective shroud shields the rear I/O connectors and surrounding VRM components from physical impacts and static buildup.
Solid Capacitor Design
Equipped with ultra-reliable solid caps that offer stable performance and an extended lifespan under harsh operational conditions.
High-Density Glass Fabric PCB
Features a specialized weave pattern that protects the copper internal traces from humidity-related electrical shorts.
Storage Interfaces and PCIe Lane Distribution
Flexible expandability for expansion cards and high-speed drives
SATA Express 10 Gb/s
Combines PCIe and SATA technologies to allow solid-state drives to break past the traditional 6 Gb/s SATA interface limits.
Six SATA3 Ports
Standard 6.0 Gb/s connectors offer plenty of expansion potential for massive multi-HDD storage arrays and optical drives.
Dual PCIe 3.0 x16 Slots
Supports multi-GPU configurations using AMD Quad CrossFireX technology via a dual-slot layout running at x16 and x4 modes.
Legacy PCI Expansion
Three physical PCI slots let users migrate legacy sound cards, RAID controllers, or specialized diagnostic gear without adapters.
Flexible PCIe x1 Slot
An open-ended PCIe 3.0 x1 slot accommodates smaller expansion hardware like Wi-Fi adapters or capture cards.
Enhanced Audio Isolation and ELNA Capacitors
Warm, noise-free sound reproduction for gamers and media enthusiasts
ELNA Audio Capacitors
Feature a low leakage current of only 3uA, drastically reducing background hiss and static for crystal-clear playback.
Realtek ALC892 Codec
Delivers robust 7.1-channel high-definition audio, ideal for immersive surround-sound gaming setups and movie nights.
PCB Isolation Shielding
An integrated physical line separating the audio layout protects analog signals from digital interference across the board.
Premium Content Protection
Full hardware support for premium Blu-Ray audio codecs ensures that high-quality media plays back with lossless fidelity.
Flexible Front Panel Header
Auto-detecting audio header detects headphone impedance automatically to optimize signal strength on front-panel jacks.

Setup Tips
Verify RAM Voltages
If you are utilizing legacy DDR3 modules, check their voltage specifications. Low-voltage DDR3L (1.35V) is optimal for minimizing wear on the CPU integrated memory controller.
Clear CMOS on First Boot
If switching from DDR3 to DDR4 or vice versa during hardware reconfigurations, perform a physical CMOS reset using the jumper to clear stored RAM training parameters.
Optimize Fan Curves
Configure the CPU fan target temperatures inside the UEFI BIOS system to run quietly when the system is idling and ramp up under heavy loads.
Update to Latest BIOS
Install the newest BIOS version from Asrock's official website using the Instant Flash tool to ensure the highest level of compatibility for 7th Gen CPUs and DDR4 memory modules.
