I have a asus p5sb MB and a k62-475 that want to get married but the p5sb doesn't like the AMD's insistance
on 2.0 core voltage and says 2.1 is as low as I go
unless the jumper setting "inhibit"? is 2.0 (undocumented?) I can jumper for 95mhz and 5x to get 475 but I can't set core to 2.0.
does anyone have sound advice on using a "notebook" CPU this MB. Like will they kill each other
if I force them together at say 95 Mhz and 5X or maybe
!00Mhz at 5x with the core voltage at 2.1.
I know this probably sounds stupid to ask but the place that sold me the CPU insisted it had to be at 2.0
volts.
Help somebody!
thanks

I've set up several of the K6+ CPUs on desktops with good results. Although I used the K6III+, the methods should be the same.
I have no experience with the motherboard that you're using, the first suggestion I would have would be to visit the motherboard manufacture's web site to see if there's any information there. You may need a BIOS update, I did on the FIC VA503+ board.

As far as the FSB, I understand that the K6's, particularly the K62's don't like a lot of FSB, but I think 100MHz should be alright. Try for 5*100.

With the voltage, I've had to increase mine to 2.4 on one of the FIC 503 boards (I have a K6III+450 running at 616MHz , 5.5*112). I see no problem with a little increase over default, I'd try to keep it under 2.5.

Keep in mind that an increase in voltage will mean an increase in heat. Make sure that you have adequate cooling. A socket A heat sink will fit nicely and do a great job. I've used Global Win FOP 32's.

Beyond that, all of the standard accepted overclocking methods and precautions will apply in this case as well.

One thing to keep in mind, it is easy to get caught up upgrading an older platform and still be saddled by the limits on board, slower memory, ATA33 hard drive etc. With the ever declining prices of the newer socket A components, you can put a decent system together fairly inexpensively today. A decent motherboard can be purchased for well under $100.00 with on board sound and a DURON CPU can be had for less than $50.00. If you have other peripherals that can be migrated over to a new motherboard, then this may be a better upgrade path that you might want to investigate.
