K6 voltage requirement

Post by Stedman5040 »

I have a FIC VA503+ board and I am unsure as to whether the applied cpu voltage is correct. The board managed to fry a K6-2 cpu to a crisp. I tried a normal k6/233 @ 250 (2.5x100) using no jumpers ie 2.0v. The board started up no problems at all. Oh dear I thought a 3.2v cpu starting up at 2.0v

Anyway I tried the same cpu in my GA-5SMM board at 2.0v using 200MHz (2x100fsb) And it starts up no problem. This seems crazy to me. A nominal 3.2v core cpu starting up at 2.0v. I tried the cpu at 1.8v and again it starts up at 200MHz.

Has anyone seen this before?

mmh,

I would try to narrow the problem down by looking at
- what the bios reports for voltage AND temperature
- what some utility (mbm for example) reports reports from within windows

if the voltage report is "broken" or not available it might help to watch the temperature alone. I would pick a cpu I know the temps of at a certain speed (as reported by another motherboard) and plug it in to see how it does. if the temperature is far above (all settings equal, same fan/cooler) then you can fairly say that you are running the cpu at a higher voltage.
