3.6X faster DOOM! Sneaky IBM Tried to hide how fast their board actually was!

In this vintage computer modding video, I unlock the true potential of an IBM motherboard and make DOOM run 3.6x faster. By modifying the board and overclocking from the original 25MHz to an incredible 120MHz, I reveal performance IBM tried to hide. Perfect for retro computing fans, vintage IBM enthusiasts, and DOS gaming lovers, this video explores extreme overclocking, motherboard mods, benchmark testing, DOOM performance, and pushing classic PC hardware far beyond factory limits. - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics - Part 1: Repair of PSU and CPU. here:    • You're not going to believe what I found i...   Part 2: Hacking the MOBO: here:    • Motherboard mod for 2.5x speed increase. I...   Part 3, Building a 486 Socket blaster here:    • 486 Socket Blaster, Adding 3.45v support t...   Part 4, Overclocking: This video!
