Delivering up to 64 Gb/s data transfer speed, the dual M.2 connectors design provides an ideal storage solution while also supporting in RAID modes.GbE LAN with Bandwidth ManagementGbE LAN features a network bandwidth management application which helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 SupportHDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 Gb/s of bandwidth twice times more than previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers.The Industry's Leading LAN Static-Electricity & Surge ProtectionGIGABYTE motherboards use ICs with up to 3 times the ESD resistance levels compared to traditional ICs. This helps to better protect the motherboard and its components against potential damage caused by static electricity. GIGABYTE motherboards also feature special anti-surge ICs that protect your motherboard, and your PC from any surge in power delivery that may occur, helping to ensure that your PC is equipped to deal with any potentially irregular and inconsistent power delivery.COOLINGSmart Fan 5With Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.5 Temperature Sensors2 Fan Pin HeadersAll Fan Pin Headers Upgraded to Hybrid Fan HeadersInteroperable Fans and SensorsIntuitive UI for Fan ControlFAN STOPAchieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperatureall of it can be customized to your liking.Hybrid Fan Pin HeadersAssume complete control over your liquid cooling setup! Smart Fan 5 receives up-to-the-second information on flow-rate and water-temperature through the Hybrid Fan Pin Headers or external thermistor sensorsgiving you absolute mastery over your PC. All Hybrid Fan Headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode.New Smart Fan 5 SoftwareChoose from different modes, Quiet to Full Speed, to match your system usage preferences.For each fan or pump, you can use the intuitive fan curve to define trigger thresholds and corresponding fan speeds.AUDIOHigh-End Audio CapacitorsGIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects for gamers.Audio Noise GuardGIGABYTE motherboards feature an audio noise guard that essentially separates the boards sensitive analog audio components from potential noise pollution at the PCB level.ULTRA DURABLEGIGABYTE Patented Double Locking BracketDouble locking bracketFirst LockInserted from the top for better retentionSecond LockSoldered for a stronger bondSolid Pin Power ConnectorsB550 motherboards feature solid plated ATX 12V 8pin power connectors for offering stable power supply while CPU overloading.Solid Pin Power connector advantagesLarger contact area for electricityMore metal quantity to sustain higher power and generated heatUltra durable and longer lifespanSTART SULFURIZATION PROTECTIONSulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design GIGABYTE gives Ultra Durable Motherboards a whole new meaning.The Industry's Leading Surge ProtectionGIGABYTE motherboards also feature special anti-surge IC that protect your motherboard, helping to ensure that your PC is equipped to deal with any potentially irregular electrical spikes.Humidity Protection Glass Fabric PCBThere is nothing more harmful to the longevity of your PC than moisture, and most parts of the world experience moisture in the air as humidity at some point during the year. GIGABYTE motherboards have been designed to make sure that humidity is never an issue, incorporating a new Glass Fabric PCB technology that repels moisture caused by humid and damp conditions. Glass Fabric PCB technology uses a new PCB material which reduces the amount of space between the fiber weave, making it much more difficult for moisture to penetrate compared to traditional motherboard PCBs. This offers much better protection from short circuit and system malfunction caused by humid and damp conditions.High Temperature Protection Lower RDS(on) MOSFETs DesignGIGABYTE motherboards use Low RDS(on) MOSFETs which reduce energy wastage through unnecessary residual heat dissipation. This all amounts to tangible energy savings which are beneficial for both end-users and the environment without impacting system performance.SpecificationCPUAMD Socket AM4, support for: AMD Ryzen 5000 Series/ Ryzen 5000 G-Series/ Ryzen 4000 G-Series and Ryzen 3000 and Ryzen 3000 G-Series ProcessorsChipsetAMD B550Memory4 x DDR4 DIMM sockets supporting up to 128 GB (32 GB single DIMM capacity) of system memorySupport for DDR4 4733(O.C.) / 4600(O.C.) / 4400(O.C.) / 4266(O.C.) / 4133(O.C.) / 4000(O.C.) / 3866(O.C.) / 3733(O.C.) / 3600(O.C.) / 3466(O.C) / 3400(O.C.) / 3200 / 2933 / 2667 / 2400 / 2133 MHz memory modulesDual channel memory architectureSupport for ECC Un-buffered DIMM 1Rx8/2Rx8 memory modulesSupport for non-ECC Un-buffered DIMM 1Rx8/2Rx8/1Rx16 memory modulesSupport for Extreme Memory Profile (XMP) memory modulesOnboard GraphicsIntegrated Graphics Processor with AMD Radeon Graphics support:1 x DisplayPort, supporting a maximum resolution of 5120x2880@60 Hz1 x HDMI port, supporting a maximum resolution of 4096x2160@60 HzAudioRealtek Audio CODECHigh Definition Audio2/4/5.1/7.1-channelLANRealtek GbE LAN chip (1 Gbps/100 Mbps/10 Mbps)Expansion Slots1 x PCI Express x16 slot, integrated in the CPU:AMD Ryzen 5000 Series/3000 Series Processors support PCIe 4.0 x16 modeAMD Ryzen 5000 G-Series/4000 G-Series/3000 G-Series Processors support PCIe 3.0 x16 mode1 x PCI Express x1 slot, integrated in the Chipset:Supporting PCIe 3.0 x1 modeStorage Interface1 x M.2 connector (M2A_CPU), integrated in the CPU, supporting Socket 3, M key, type 2280 SSDs:AMD Ryzen 5000 Series/3000 Series Processors support SATA and PCIe 4.0 x4/x2 SSDsAMD Ryzen 5000 G-Series/4000 G-Series/3000 G-Series Processors support SATA and PCIe 3.0 x4/x2 SSDs1 x M.2 connector (M2B_SB), integrated in the Chipset, supporting Socket 3, M key, type 2280 SSDs:Supporting PCIe 3.0 x2 SSDs4 x SATA 6Gb/s connectors, integrated in the Chipset:Support for RAID 0, RAID 1, and RAID 10USBCPU:4 x USB 3.2 Gen 1 ports on the back panelChipset:2 x USB 3.2 Gen 1 ports available through the internal USB header6 x USB 2.0/1.1 ports (4 ports on the back panel, 2 ports available through the internal USB header)Internal I/O Connectors1 x 24-pin ATX main power connector1 x 8-pin ATX 12V power connector1 x CPU fan header1 x system fan header2 x M.2 Socket 3 connectors4 x SATA 6Gb/s connectors1 x front panel header1 x front panel audio header1 x USB 3.2 Gen 1 header1 x USB 2.0/1.1 header1 x Trusted Platform Module (TPM) header (2x6 pin, for the GC-TPM2.0_S module only)1 x Clear CMOS jumperBack Panel Connectors1 x PS/2 keyboard/mouse port1 x DisplayPort1 x HDMI port4 x USB 3.2 Gen 1 ports4 x USB 2.0/1.1 ports1 x RJ-45 port3 x audio jacksI/O ControlleriTE I/O Controller ChipH/W MonitoringVoltage detectionTemperature detectionFan speed detectionFan fail warningFan speed controlBIOS1 x 128 Mbit flashUse of licensed AMI UEFI BIOSPnP 1.0a, DMI 2.7, WfM 2.0, SM BIOS 2.7, ACPI 5.0Unique FeaturesSupport for APP Center@BIOSEasyTuneSmart BackupSystem Information ViewerSupport for Q-FlashOperating SystemSupport for Windows 11 64-bitSupport for Windows 10 64-bitForm FactorMicro ATX Form Factor; 24.4cm x 24.4cm-Socket: AM4CPU Compatibility: AMD RyzenChipset: AMD B550Form Factor: Micro ATXMemory Slots: DDR4 - 4 SlotsM.2 Compatibility: USB C: No
