Up for sale is an extremely rare Multiplier unlocked Pentium 2. These were only made in early runs of the Pentium 2 manufacturing, at which point Intel locked them down. I tested it at 400 Mhz and 200 Mhz just to be sure the multiplier was unlocked. I took screenshots to show it, as well as Quake Speed test runs to make sure it was stable. The 333 speed test shows a strange Processor speed, but it is clocked right, and the Quake speed test proves it.
These are great for retro setups as you can clock it down super slow by disabling the cache and a lower multiplier. The lowest my board would go is 2.0X, but with a better board, you may be able to go lower.
Please let me know if you have any questions.
