In this case, however, the problem arose after a certain period of time (in which I never made the world, BTW). This isn't usually due to a design flaw in the chip itself. > > It may be simply a matter of this present rev of the K6 is > > defective and when AMD does their next, they'll fix this. > > Any thoughts, people?? > All I can say is that I have a chip here that is flakey that worked fine > for the first 2 weeks or so. Others have reported identical experiance. Hm, with me it's _ONLY_ cc that fails (i usually have my machine running round-the-clock or at least 18 hours a day. Once I tried a make world after 24 hours of working fine, and after half an hour or so it went "tilt". In fact, I never had trouble with ANYTHING but cc, and ONLY when in a "make-world" environment, and the machine NEVER crashed or so except for other hardware mischief that I'm doing. > I contacted AMD and they are in extreme denial saying basically that it's my > problem, there is no warranty, and there is nothing wrong with their chip. > About the no warranty: they say that the warranty claim must be made to > the supplier and not to them.

I am still in doubt whether it is ONLY the K6 or whatever. Might be useful if I posted my configuration again: ASUS TX97 Mainboard (said to support the K6 up to 233 MHz). Thermals can't really be a problem, because if the processor overheats, the board goes into "slow" mode. It never did. AMD K6-200; 64 megs of RAM (4x16 MB PS/2 FPM 60ns, board configured for 60 ns FPM DRRAMs - should be OK, especially since i had used the same 64 megs in an AMD 486 at 160 MHz with extremely -well- experimental timings and they worked fine) The other junk, like Adaptec 2940U and HD and CDROM and graphics card (MGA Mystique) shouldn't really matter.
