Some people look at specifications as a requirement, and others look at them as a challenge. You’re reading this on Hackaday, so you know where [Necroware] falls. In the video below the break, you’ll see how he takes a common mid-to-late 90’s motherboard and takes it well past its spec sheet.
[Necroware] does what all soldering iron ads think people finish with soldering ironsHaving already started with replacing the real Time Clock with his own creation, [Necroware] looked for other opportunities to make the Asus P/I-P55TP4XEG much more capable than Asus did. And, he succeeded. Realizing that the motherboard has the ability to have an external voltage regulator board, [Necroware] made one so that the Socket 7 board could supply much more than a single voltage to the CPU- the very thing keeping him from upgrading from a Pentium 133 to a Pentium MMX 200.
While the upgrade was partially successful, a deep dive into the Socket 7 and very Socket 7 documentation helped him realize the need for a pullup resistor on a tactical clocking pin. Then, [Necroware] went full Turbo and smashed this author’s favorite single core CPU of all time into the socket: the AMD K6-2 450, a CPU well beyond the original capabilities of the board.
It really goes to show that, of course, It’s All about The Pentiums. thanks to [BaldPower] for the doing the needful and dropping this terrific hack into the suggestion Line!
