I have just fitted a 200 MMX processor on to a Advanced/ML motherboard but have realised (according to the Intel FAQ) that I can't run MMX on this board. Can anyone please tell me if a) it will cause any damage to the board or the processor (I've changed the necessary jumpers although I am using it with voltage set to 3.3-3.465v)... and b) am I actually gaining any sort of speed improvement which is worthwhile? (obviously all speed improvement is worthwhile, but am I running close to a standard 200)?

Thank you in advance.

Dear Sir:

The Intel(R) Advanced/ML motherboard commonly referred to as the Marl does not
support the Pentium(R) processor with MMX(TM) technology. It does not have
support for the split plane voltage. The core of the MMX(TM) processor is 2.8
volts unlike the normal Pentium(R) processor, which is around the 3.3 volt
range. It is possible to cause damage to the processor and or the motherboard.
The upgrade path for this motheboard would be the 200-MHz Pentium(R)
OverDrive(R) processor with MMX(TM) technology, the part number for this
processor is BPODPMT66X200. You also may want to check the motherboard for the
AA and or PBA number on a sticker on the motherboard itself to ensure that this
is the Intel version of the Marl motherboard and re post with those numbers so
we can check for you.

Thank you for your speedy response. I have since taken out the 200MMX to ensure that no damage occurs. The AA number of my motherboard, as requested is:
AA655377-202.

As I only purchased the processor yesterday I have taken it back to the supplier and changed it for a standard Pentium 200, as they had no 200 overdrive MMX's (I didn't want the additional outlay either - as I intend going updating the motherboard later this year anyway). Unfortunately this has no number which I can look up on your website to see the voltage required. Your CPUID program identifies it as a genuine Intel. The only two numbers I can see on it, without picking at the "void if removed sticker" are C010592 and AS13587. The top of the chip shows only i200.

Currently my VR/OVD jumper (J7K1-B) is set to 1-2,4-5. (which is how it was purchased with a 133 on board. Please can you inform me if this correct. Also, apart from the necessary changes to the J7K1C/D jumpers if there anything else I need to change to ensure the system is a) set up correctly and b) working at it's optimum performance.

Dear Darren:

The information you have provided corresponds to the Intel(R) Advanced/ML
motherboard. You currently have the jumper set, for the processor voltage, to
OVD or the standard setting of pins 4-5 on jumper J7K1-B. The only way to ensure
that you have the right setting is from the SPEC number on the processor, you
would need to check the top or bottom of the processor. On the bottom it will
have the SPEC number and then some extra alphabetical characters. These
characters normally will start with V or S, V for VRE or S for standard, This
will help you to determine the correct setting for the processor voltage or you
can check the SPEC number on the web site, as you mentioned, for further
confirmation.
