A collection of issues I’ve diagnosed and resolved across hardware, software, and systems.
Memory Instability Under Stress Due to Memory Frequency Incompatibility
Category: Hardware
DDR5 system crashing under high memory bandwidth workloads. Diagnosed as a frequency incompatibility between the installed capacity and motherboard specifications. Resolved via BIOS downclocking with no performance degradation.
DSL Connectivity Fault Diagnosis and Cable Replacement
Category: Networking
Intermittent DSL dropouts traced through systematic elimination from ISP infrastructure inward. Resolved by replacing an aging RJ11 cable with degraded signal integrity.
