A ok then does not support the P.MMX or yes?
If it doesn't support it, you need to figure out how to make the mod to power it properly (add dual voltage).
The images I asked for were used to understand if it was a model born for normal Pentium, many i430VX can support MMX only if dual voltage is available, and from what I understand this card does not support it either.
I'll take a look at the link, but I doubt it's a simple thing to do (mod).
It supports mmx perfectly, i already tested 5 games all of which give me the results of a pentium 166 mmx (like quake running at 42fps) the motherboard is compatible and set for mmx, check the first post.
Ok that works, but you have to understand how?
From what I understand does it work on single voltage (overvolt), or do you have the correct voltage?
To check it is simple, you can use a tester, black probe inserted in the power supply connector for HD CD-ROM in correspondence with the black wire, set to measure the Volt DC (up to 20V), measure the voltage on the said of the mosfet, one of the three (or two?) measures about 3.3V, the other should measure about 2.8V, if you don't find this voltage the cpu is overvolted, and this could create problems.
If you can make these measurements, then you will have to make attempts at various frequencies to understand if the problem is in the CPU or in the MB, of course you could do them even now but I would like to understand if the CPU has the correct voltage, and if the problem of functioning at 200MHz is due to the overvolt.
