ERROR_MEMORY_HARDWARE - 779 (0x30B)
The hardware has reported an uncorrectable memory error.
Updated: Feb 21, 2026
Technical Background
The ERROR_MEMORY_HARDWARE error code, with the numeric value of 779 and hexadecimal representation of 0x30B, indicates that an uncorrectable memory error has been reported by hardware. This error is specific to issues within the system's memory subsystem.
Error Details
This error typically arises when a memory module or component fails in such a way that the operating system cannot correct the issue through standard error correction mechanisms. Such errors can be indicative of physical damage, faulty components, or other hardware-related issues.
Common Causes
- Faulty Memory Modules: Physical damage to RAM modules or soldering issues on the motherboard can lead to uncorrectable memory errors.
- Motherboard Issues: Faults in the motherboard's memory controller or related circuitry may cause such errors.
- Overheating: Excessive heat can degrade memory performance and potentially lead to uncorrectable errors.
Real-World Context
This error is critical for system stability as it indicates a hardware failure that could affect data integrity. Developers should be aware of this error when handling sensitive or mission-critical operations.
Is This Error Critical?
Yes, the ERROR_MEMORY_HARDWARE is critical and can lead to data corruption or system instability if not addressed promptly.
How to Diagnose
To diagnose this issue, developers and administrators should:
- Review Operation Context: Ensure that all memory-related operations are performed within a valid context.
- Validate Parameters: Verify that the parameters passed to memory-related functions are correct and within expected ranges.
- Confirm Object Types: Confirm that the objects being manipulated are of the correct type (e.g., ensuring that pointers or references are valid).
- Verify Input Data: Check for any corrupted data that might be causing the error.
How to Resolve
To resolve this issue, consider the following steps:
- Correct Parameter Usage: Ensure all parameters used in memory operations are correct and up-to-date.
- Adjust Operation Context: If the operation context is incorrect, adjust it to a valid state before retrying.
- Restore Data: If data corruption is suspected, attempt to restore from backups or other reliable sources.
- Retry Operation with Valid Inputs: Retry memory operations with validated inputs and ensure that all prerequisites are met.
Developer Notes
Developers should handle this error by implementing robust error handling mechanisms in their applications. This includes logging the error for further analysis and taking appropriate corrective actions to prevent data loss or system crashes.
