How to Troubleshoot Gigabyte Motherboard’s Different Error Codes?

Below is a more in-depth look at a few prevalent Gigabyte error codes encountered, explaining the meaning behind these codes plus systematic troubleshooting solutions to attempt:

00 – Not Used

The 00 error code indicates normal functionality, as all initialization processes and components have passed POST with no issues detected. So if your system boots to 00 on the motherboard’s diagnostic display, there is no present error – the system is operating as expected. Generally, no troubleshooting steps are necessary for code 00.

50 – 54 – Memory Initialization Errors

Error codes in the 50-54 range pertain to RAM issues halting the initialization process during boot-up:

• 50 – Memory initialization error occurs
• 51 – Memory initialization error occurs
• 52 – Memory initialization error occurs
• 53 – Memory initialization error occurs
• 54 – Memory initialization error occurs

If your Gigabyte motherboard is stuck displaying any 50-54 code, the culprit is likely faulty or improperly connected RAM. Try the following RAM-related fixes:

• Reseat RAM sticks in their slots to ensure proper contact
• Test RAM sticks individually to isolate failures to specific stick(s)
• Try RAM sticks in different slots in case slot failure at play
• Update motherboard BIOS/UEFI in case of compatibility issues
• Finally, replace RAM sticks if testing reveals permanent faults/failures

So check for physical connection issues first, then test sticks individually before deeming cursed and replacing.

D2/D4 – PCI Allocation Error

Both code D2 and D4 pertain to PCI allocation issues during POST initialization:

• D2 – PCH initialization error.
• D4 – PCI resource allocation check error.

These PCI-related errors suggest your hardware may be drawing too much power from the bus, or assignment conflicts exist. Potential solutions include:

• Remove any unnecessary PCI and PCI-E devices to reduce power drain
• Reset CMOS to allow re-detection of connected devices
• Update to the latest stable BIOS version
• Reseat expansion cards in their slots

Start by eliminating non-essential devices drawing PCI bus resources first during troubleshooting.

56 – 57 – Invalid CPU Type or Speed/CPU Mismatch

Codes 56 and 57 relate to processor-compatibility errors:

• 56 – Invalid CPU type or Speed
• 57 – CPU mismatch error

If you recently changed processors, these codes can stem from the new CPU not being supported by the installed BIOS version. Or the code may signal the opposite – outdated BIOS not supporting your modern CPU. Fixes to try:

• Update motherboard BIOS to latest stable version
• Reset BIOS settings to defaults if overclocking enabled
• Reinstall previous compatible CPU if available
• Ensure processor properly inserted in socket

Updating BIOS is often key to resolving CPU-related error 56/57 issues.

62 – Installation of the PCH Runtime Services

Error 62 indicates failure initializing the Platform Controller Hub (PCH) Runtime Services during the boot sequence due to an improperly seated processor:

• 62 – Installation of the PCH Runtime Services

Before attempting BIOS reconfiguration or firmware updates, ensure your processor is properly installed:

• Reseat CPU in the socket, ensuring alignment of pins
• Check socket pins for any damage preventing contact
• Confirm CPU fan power connector is plugged in

A simple reseat can fix code 62 if the processor became slightly out of alignment from movement/vibration.

99 – Super IO Initialization

Error code 99 pertains specifically to initialization failures with the motherboard’s Super I/O controller chip:

• 99 – Super IO Chip initialization error

The Super I/O chip controls connectivity of integrated input/output devices. If code 99 appears, suspect an issue with the physical integrity of this chip. Troubleshoot by:

• Ensuring Super I/O chip module is properly seated
• Checking socket pins for any obvious damage
• Finally, replacing the motherboard if reseating does not resolve

This is one error code that usually requires motherboard replacement if chip-reseating does not work.

A0 – IDE Initialization Is Started

• A0 – IDE initialization is started

Code A0 signals that the POST process has reached IDE hard drive initialization. It generally indicates a hard drive connection or configuration issue:

• Check SATA and power cables to all drives for loose connections
• Update motherboard firmware/BIOS to latest IDE drivers
• Disable any RAID controller functionality and enable AHCI mode
• Attempt boot with single drive attached during testing

So unlike other error codes, A0 is informational only – proceed to check drive health and connectivity.

A2 – IDE Detect

• A2 – IDE hard drive detect error

Similar to A0, error A2 suggests a problem detecting your connected storage drives:

• Confirm SATA cables properly connected from drives to motherboard
• Inspect SATA ports and cable connectors for bent pins or damage
• Update motherboard BIOS to latest stable version
• Check for drive failure/replacement if issue persists
• Consider switching from IDE/RAID to AHCI drives

Drive cables connections should be checked first. Also, migrating drives to AHCI can improve detection issues.

Other Troubleshooting Tips for Gigabyte Motherboard Error Codes

Here are a few additional things to check when encountering POST error codes on a Gigabyte motherboard:

• Clear CMOS Memory Button – Pressing this button resets BIOS, which can resolve initialization issues and provide a fresh start. Consult your motherboard manual on the jumper location.
• BIOS Update – While updating BIOS to the latest firmware version should not be the first step taken, it can definitely resolve compatibility issues at play with certain error codes. But proceed with caution only if the system is stable.
• Reduce to Minimum Configuration – Remove unnecessary PCI cards, hard drives, and RAM sticks to minimum essentials to help isolate faulty components producing error codes.
• Check Connectors and Cables – Reseating both power and data connections (SATA/HDD, 24-pin ATX, etc.) often fixes elusive contact issues causing codes.

Error codes on Gigabyte motherboards provide insight into exactly what component or initialization process is failing during boot-up. While frustrating to diagnose, methodically checking connections, reducing devices, reseating parts, and testing sticks/drives can isolate and fix the underlying problems signalinged by POST error codes.
