INTEL PENTIUM 200 MHZ - CLASSIC OR MMX

By ROM2001 ·
I have a motherboard that can be upgraded up to Pentium 200MHZ "CLASSIC" processor. Can my motherboard work if i upgraded my processor to a Pentium 200 MHZ with "MMX"? It is an old motherboard and I currently use a Pentium 133 MHZ processor.

Sorry, your 200MMX chip will not fit in the motherboard due to the pin configuration of the socket on the motherboard. A pentium pro chip will not fit either, both these chips have more pins on the processor than the socket has.
Good luck!

Answer # 1 is thinking of the 233 Mhz Pentium II.
The pin outs of a 133 MHz Pentium and a 200MMX Pentium are the same.
The difference is, the Classic Pentiums use 3.3 Volt for both I/O and Core.
The MMXs use 3.3Volts for the I/O and 2.8 Volts forthe Core.
This is regardless of the processor speed.
They used to sell aftermarket voltage regulators so you could plug the MMX into the regulator, and then plug the regulator into the motherboard.
I do not recommend this.
It is usually much more effective to upgrade the Video Card.
The current Video cards can out render, even the fastest PC CPU.
The other thing to check is the amount of RAM installed, and the amount free during max load.

Technically, BOTH of the above answers are misleading. What determines whether the 200MMX will fit ( never mind work!) is whether the board has a Socket 5 or a Socket 7 CPU socket. A 200MHz Pentium Classic will fit in a socket 5 Board AND will fit in a socket 7 board, but unless the Socket 5 board has multiplier jumpers for BF0,BF1 AND BF2, you won't be able to get a Socket 5 Board much past 166MHz (66x2.5). The MMX will ONLY fit in a Socket 7 board (it does have a few more pins than a classic), and will ONLY work if you have a split voltage regulator (look for jumpers for VCORE/VREG etc) If you have no obvious regulator IC and no voltage jumpers for VCORE then the 200MMX will not work (and WILL be damaged at 3.3v).

To find out more.....look up the BIOS ID string on www.motherboards.org or www.wimsbios.com. From that, identify your mobo and then link to the manufacturers site for info on the board's capabilities.
