can an AMD k6 II or III CPU run on a socket 7 TX chip set?

[Weed]

just wondering.........

The voltage on the TX doesn't go low enough.

Wouldn't that be dependent on the different motherboards? I have a VX board that goes down to 2.0v in .1v increments. My K6-2+ works great on it. It is the only VX board I have ever seen that goes that low. I would guess since TX is newer there would be more mobos based on it that support low voltages.

I also think it depends on the mobo. I asked Abit the same question about my PX5 which as the TX chipset and they categorically stated that the PX5 would not support K6-2s. This was independent of the voltage, which I could only get down to 2.5, whereas the 'upper limit' of the K6-2 I wanted was 2.4.

Another factor is the total wattage requirements of the chip vs the wattage limit of your board. Most TX chipset boards have a max of something like 10 watts. I wanted to put in a K6-2 400 which drew about 15 watts at peak. Several people expressed skepticism about this.

There was a thread about this almost a year ago. Everyone said it could theoretically be done but I haven't heard from anyone who actually did it.

All those older motherboards support up to 66 Mhz bus speed. The motherboard might go up to 75 Mhz or so, but the AMD K6-2 and K6-3 should work at those bus speeds(Basically downclocking from 100 Mhz to lower frequency). You just have to work with the clock multiplier and voltage setting that is on that TX motherboard.

Well, I read on Tom's Hardware that he got a even newer, K6-2+ running on a very old Asus motherboard that used the VX chipset. Considering that the board has the voltage, and the fact that the TX Chipset is newer, I don't see why it wouldn't.

Niege--I believe my K6-233 pulled 24 watts. Not sure, but it rings a bell. If so, if you mobo supports that, it would handle the wattage for the newer.

Lupen--Yes, you can underclock them, or overclock to 75 or 83. They do not have to run at 100. My FIC PA-2012 ran a K6III-350 @ 75mhz (officially unsupported) with 4.5 multiplier = 337 (at 2.1 volt). Also, I've been told in the forum that 2X is remapped to 6X on these cpu.
