I have an intel motherboard that will accept up to 233 mmx processor(socket7) is there anyway I can use an amd k6 233 or higher processor and if there is do I leave thee jumpers set for 233mmx

The only difference will be the CPU voltage setting. The buss speed and clock The multiplier settings are the same as the Intel chip. I am not sure but I think some k6233's require 2.2 volts and some require 3.2 volts. The Intel MMX233 required 2.8 volts Look at your K6 chip, if you have it and see what voltage is required. Then look and see if the motherboard settings will allow that voltage. As far as using anything faster, your board probably only supports 66hz buss speed. You need to see if it supports any greater multipliers than 3.5X.

Is that really an Intel mobo? In most cases only the chipset used on it is actually made by Intel.
Find out the mobo manufacturer and the model. Then look it up on the AMD website www1.amd.com/K6/k6mbl (http://www1.amd.com/K6/k6mbl) under their Motherboard Compatibility section to see if it is listed and what is the fastest CPU it can take.
My own 430TX mobo (by Elitegroup) can take an AMD K6-2/300MHz. (The manual says only up to Intel 233MHz but the manual was printed long before the K6-2 was invented.) But your BIOS may be different, possibly Intel only, etc. So you may also need a BIOS upgrade.

This is an intel motherboard and the voltage is 3.3-3.465..

IF those are the only choices, then you can't plug a K6 directly into the MB. However, there are some companies that make upgrade kits. I have never used one but I think what they do is put an adapter between the new CPU and the MB that steps down the voltage and changes the CPU multiplier. Evergree is one and I think there are others.

YOU may be able to upgrade to 400mhz! Yes, 400!
I doubt that you have only the voltages you listed, that sounds like I/O voltage to me and not CPU core, an Intel Pentium MMX processor (which your board supports) uses 2.8-2.9volts CORE so you better do a little more investigation to see what you really have.
Research that board at the mfgr's website if possible - if it supports any CPU CORE voltage 2.2 to 2.4v you can run a AMD K6-2 at 400mhz, Yes, 400mhz! The K6-2 400 is an unusual animal in that the 2times multiplier has been remapped to act as a 6times multiplier. IN OTHER WORDS::: if you set the multiplier to 2times the 66mhz bus speed then you get 6x66=396, or an AMD K6-2 running at 400mhz. The K6-2 400 is currently about $79.
FYI: The K6 233 runs at 3.2v core, but I ahve run them fine at 2.9 to 3.2 and at less than 3.2 they run a lot cooler. Although, if all you want is to go with an 233mhz chip I would recommned the Pentium 233MMX instead of the K6 233 - cost is about $49 for either.
By the way, there is also a voltage adapter for the K6-2 available that goes between the CPU and motherboard, but the thing costs around $40, and that is 1/2 the price of a new motherboard, so in the long run the adapter isn't worth it.

hmmm . . . interesting, CMonster. Thanks for the info. Might be worth trying on my board if I come across a really cheap 400MHz in my travels. Put off the inevitable mobo upgrade just a little bit longer.

I have tried it on two of my TX motherboards and it does indeed work...now to buy two more K6-2 400s so that I can make the upgrade permanent...no more musical CPUs...
But what will I do with those 233 CPUs?

I happen to have one of these boards and know something about them. It is an Intel motherboard, AN430TX also know as the 'Anchorage'. You can indeed upgrade it, but you will need a voltage adapter to get much running in it. I've had a a K6-2, and even a K6-3 running on the one I have with a voltage adapter. If you are looking to avoid the hassle of upgrading the motherboard, an adapter and chip would not be a bad way to go. Look around for a Powerleap or Evergreen Technologies upgrade. The cost may weigh in a little high for the entire upgrade as a package, but you do get some support in getting it to work.
If you are just looking at it from the money standpoint and think you can tackle a motherboard upgrade, something more like a Celeron and motherboard would cost around the same and give you much better performance. You can also upgrade a new motherboard later, where upgrading this one is a dead end.

I wouldn't even try putting an AMD processor in a TX motherboard, let alone an INTEL motherboard.
The INTEL bios does not support the AMD processor, I believe.
Also INTEL's busmaster drivers require an INTEL processor to function, if that matters on a TX board.
I think if you run Win9x, you'll be OK because they have good DMA Busmastering Drivers in the OS.

Late model Intel motherboards switched to a Phoenix bios from using an AMI bios. A few of the Phoenix bioses will not work with non Intel CPUs, and all of the AMIs will not. The AN430TX can and will work as long as you can get the voltage correct. I've done it with everything from a K5 to a K6-3 in this exact board. You are limited to a 66Mhz bus, but with CXT core K6-2 and K6-3 chips you can get 400Mhz with the 6x multiplier.

Sorry I asked!! Conflicting ideas. I better stay with the 233 mmx intel chip upgrade. Interesting though. I think the bios and the voltage problems would be a pain to overcome. Besides a 233 mmx is fast enough for me. thanx

cmoster what would you want for a used 233 mmx chip. ebay is about $55 for a new one. I don;t know if I want to gamble with a used one unless it is at $25-30 range.

sorry, both sold already $40 each

Intels Busmasters sure did need an Intel CPU to work on my Abit IT5H (HX m.b.)
When I had AMD K6-200 they would stop working the second time I booted. I had to go back to their beta version to get a working Busmaster Driver.
That was a while ago. Maybe they took out the Intel CPU requirement since then. I couldn't get it to to work until I put in an Intel 200MMX http://www.sysopt.com/forum/frown.gif
