Currently Playing: Overclocking IBM PS/1 486SX25. Cooling and Power experiments (Fake buck converters!)

This video explores overclocking an IBM PS/1 486SX-25 with extensive cooling and power delivery experiments. I test multiple 486 and 5x86 CPUs, experiment with different buck converters, and stress the system under load to measure stability and performance, including spotting fake buck converters. Ideal for fans of vintage computers, retro IBM systems, 486 hardware, 5x86 upgrades, classic PC overclocking, power regulation mods, old-school PC tuning, and hands-on retro computing experimentation. - 486 Interposer here: https://www.pcbway.com/project/shareproject/486_Socket_Blaster_3V_CPU_to_5V_Mainboard_a791e096.html - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics - IBM PS/1 486 Playlist here: https://www.youtube.com/playlist?list=PLLN54H2azbhTBYFaLOonwqlQOkbl_W5Q8 - Tools I regularly use FNIRSI DWS-200 Solder station PinePower Bench PSU AMTECH NC-559-ASM Flux Kester 951 Flux pen Hanstar 861DW Rework Station Pro'sKit SS-331 Desoldering Station SEQURE HT140 Desoldering Tweezers Multicore 60/40. 0.38mm solder AOYUE int883 PCB Preheater RIGOL DHO800 70MHz four-channel digital Oscilloscope Tektronix 2246A 100 MHz four-channel analog Oscilloscope FNIRSI DPOX180H 180MHz Handheld Oscilloscope UNI-T UT61E Auto Ranging Multimeter UNI-T UT890D Manual Ranging Multimeter FNIRSI LC1020E LCR/ESR meter TL866 II Plus Programmer InfiRay P2 Pro Thermal Camera TOMLOV TM4K-AF Flex Microscope Dremel 3000 with flexible shaft MaAnt Mini"Dremel" DeoxIT D5 Contact Cleaner PCBs from PCBWay.com - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics Join me on Twitter: https://twitter.com/epictronics1 - Music by Karl Casey @ White Bat Audio
