Help me decide between K6-III+ 400Mhz or K6-II+ 550Mhz

Clock Generator is an IC Works W153BH / B810 1932FB
Haven't used Everest but will download and try it out. Thanks.

OK have tried Everest and that reports wrong too. The voltage read out for the cpu core is coming out on the +5V line. reading are reported as follows

Core 1.9V Actual 1.3V as set on MB
Aux 2.05V
+5V 1.34V
+12v 2.13V

Guess its kind of mixed up. Its reporting an LM78 sensor. I presume that is what is embedded into the 5595 southbridge. :?

BIOS update (F5)?

W153BH will do 133 MHz as you say, but I can't seem to find out more than that. I'm sure though that the undocumented settings are available for use though...

Perhaps Cypress has an old IC Works datasheet on that chip in it's archives...

Ok, folks, I got the K6-III+ 400Mhz ACR, 2.0v.

What's realistic for OC'ing?

Start with a FSB of 100MHz and try your various board multipliers - 5 and 5.5 (500MHz and 550MHZ CPU speeds) should be attainable. If all is stable on 2.0V, try for 600MHz - you will probably have to increase the core voltage to 2.1V or so at this point.

Then try upping the FSB.

Have fun!

Well, I clocked this 400Mhz ACR chip to 550Mhz/110Mhz FSB anyway, with no problems at all.
