Upgrading To A 200 mhz mmx

[Guardian]

Hello


upgrading a pentium 133 mhz to a 200 mhz mmx. i just want to know if the system will accept this chip. and how can i tell or know what is compatible with the motherboard. thanks

You must first find out what motherboard your computer is using. Who made the computer?

My guess would be that the Pentium 133 could not be upgraded to a P2 200Mhz without changing the motherboard first. I believe that you used to be able to buy a conversion for this, but as these chips are so outdated it is no longer available.

I think the makers are American Megatrends, Inc. The cpu says "upgrades 150, 166 and so on." But i dont read anywhere that upgrades 133.


Thanks

Guardian;
It depends on the BIOS of your current motherboard. If it was produced before the P200MMX was introduced it will need to be flashed with the latest issue. You will need to know who provides this support, either the motherboard manufacturer, or the computer manufacturer. If it is a custom built unit the motherboard maker is the place to look. The Pentium 200 MMX is not a PII, the PII starts at 233MHz, which is where the Pentium ends. So the P 200 will fit in the same socket (I believe it is a socket 5) as your 133 MHz. If in doubt, go ahead and install the new cpu, and see if the BIOS will recognize it. I don't remember a change in die size at that time so the core voltage is probably the same for the 2 chips.

WHOA!!!!

The 200 MMX has a different core voltage than the non-MMX chips do. If your m/b does not expressly support it - DON'T do it!!

Most of those older Socket 5 m/b had jumpers/switches on them to control the speed. Find out what the highest setting is and shop for that speed CPU. Chances are, if it can be set for 233 or 266, it will accept an MMX CPU. If not, stick to a non-MMX 200 or overclock your 133 (90% can go to 166 and 50% can hit 200).

On overclocking - make sure you use thermal paste and a good heatsink/fan combo. At the worst, you will shorten the life of your CPU by a couple years, but P166s are selling for $3 each...

1. Pentium 133-233MHz CPUs can be socket 5 or socket 7. I have boards with both. This Socket Chart (http://users.erols.com/chare/sockets.htm) might be useful.

2. To find out what CPU the motherboard will handle, use the [Pause] key to stop the boot process and write down the BIOS ID String, which is the long number at bottom left of the screen, during memory count. Take that number to Wim's BIOS (http://www.wimsbios.com) and look it up, chances are you can find a manual, which will tell you what CPU range it will handle, and whether it will handle MMX. Only use an MMX CPU in a board that will handle it, the MMX is a dual voltage CPU and the voltqages are different than standard non-MMX CPUs.

jsk2315: NEVER recommend overclocking on the PC Guide Discussion Forums. You have no idea whether the individual has the knowledge necessary to accomplish overclocking, and it is the best way I know of to turn a working computer into a fancy paperweight. If the person asks, offer information and links, but do not recommend overclocking. If the person happens to try it by changing the bus speed rather than the multiplier, it can lead to a very unstable computer and can damage components. This forum will not be responsible for damaging people's computers because someone advised them to try something they know little about. We're here to fix them, not break them.

Hello

The socket is 7 the motheboard has some clocks imprinted on it. The highest speed that is imprinted on the motherboard is 200 mhz the lowest is 75 mhz, but these are to over clock the cpu.

thanks

Guardian,
The numbers on the mobo are telling you what you can set it to too accept a faster CPU. Yes you can use this to OC, but it is meant to be able to accept that speed CPU.
Sounds like you found what you are looking for.
Good luck http://www.PCGuide.com/ubb/cool.gif

It might not take a "MMX" chip though. Maybe only a "standard" 200Mhz.
