The place I work has 3 AMD K6-2 systems: AMD K6-2 300 with 128MB PC100 Memory AMD K6-2 333 with 128MB PC100 Memory AMD K6-2 350 with 64MB EDO 72 Pin Memory All are A stepping and only the 350 has the new CXT core. None of them have stability problems. It sounds to me that either you have a bad cpu or your motherboard may have stability problems. All 3 systems are using the TMC TI5VG+ 1024K Cache MB. Depending on the memory you have, switching the SDRAM timing to 3 instead of 2 may be necessary to create a rock solid system. But keep in mind that there are some AMD K6-2 300s that are rated for 66MHz and not the 100MHz bus. The 66MHz bus ones were cheaper... However, one of my friends had an AMD K6-2 350 that worked fine (i.e, rock solid) until he overclocked the bus to 133MHz for kicks just to check out the performance. The system was not stable at 133MHz bus so when he moved it back to the 100MHz bus, the cpu would no longer compile the kernel without dumping core in the process. I guess the CPU was somehow damaged when overclocked. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
