What K6 / K6-X in a intel i82430FX mobo?

[Valis]

Can anyone tell me what AMD K6 I can put in my 430FX
mobo? According to the jumper settings it can do
3.33 - 3.6v and supports 1.5 to 3x multipler.

You can't -- without help.

K6 166-200 processor use 2.9v
K6 233 processor uses 3.2v
K6 266-300 processors use 2.2v
K6/2 266-533 processors 2.2-2.4v (depending on A-- code)

Your motherboard can only support a 3X multiplier. With a 66MHz FSB, the fastest processor your mobo can talk to is a 200. And if you put a K6/200 in there, you'll fry it. The fastest you can go is a classic Pentium 200. It won't even do a 200MMX (they need 2.8v)

If you must upgrade the old FX, www.powerleap.com and www.evertech.com offer upgrade modules that can move you up to K6-2's and K6-3's by supplying their own voltage and fooling the board into thinking they are running an internally clock-locked chip. But you'll spend more for an upgrade module than a new mobo anyway...

You MIGHT be able to get a 233K6 to run at 200. But your best bet would be to get a P200 non-MMX or just a new MB.

You can also find on Egay the Winchip 2 200 or 233. I have an old ASUS 430FX board and found one of these processors long before they (Centaur) was purchased by VIA. The Winchip2 has a 64K L1 cache and a pipelined core. They are very hard to find now (except on egay). Be sure to get the winchip 2 and not the older Winchip. Forgot, the Winchip 2 also has MMX and 3dNow! extensions (not that you were thinking of playing big time games with this rig!). Also remember this chipset can only cache up to 64MB of memory. Your next bet after the Winchip would be the P200.
