AMD chips are perfectly good, actually, and the Athlon is far better than Intel's latest (The pentium 4) in many ways, and Intel has recently released some very unreliable hardware that had to be recalled (The 1.13GHz P3 and an entire class of chipset using emmory translator hubs) Anyway, the issue with the K6 series chips has often been crappy motherboards, which AMD has no control over. Going with the "usual" good brands (Asus, Aopen, Tyan, MSI) will typically be just fine. Because the K6-x's were so cheap, many a worthless company made many a worthless motherboard. The motherboard's quality is of extreme importance for system stability, so this is obviously not a good combo. If you were using older K6-x chips, they may have been the issue since AMD made a huge screwup with these chips when they are equipped with more than a certain amount of memory (40MB, I think it was), but yours are newer so it is likely not the chips themselves. You might also have a bad power supply. While the power supply quality is nowhere near as important as it is with the power hog CPUs like the Athlon and Pentium 4, a crappy power supply may still cause system instability. Epox motherboards, as you asked, don't have a great reputation. They don't, as far as I have heard, have a bad one either, but they aren't particularly popular so I haven't really heard much either way. There are brands to avoid, but that isn't really relevant here so I won't list them. Note that I know of two people that are running servers on K6's. While they are definitely not server grade hardware, they work fine. If the motherboard is the problem, you might try: Going into bios and reducing the memory timings. Set them to the highest numbers available (CAS 3, or if you get to set the CAS, RAS and precharge, set them all to high numbers) Play with the AGP aperture size. While this cannot possibly have anything to do with system stability (it is the amount of RAM allowed for use as AGP texture memory, but the amount chosen is actually about twice the allowed amount), it has with several systems that I have worked on in the past. No idea. Turn motherboard L2 ECC checking on, if supported. Reducing the interface speed of the hard drives would normally be something to try, but FreeBSD doesn't care what the BIOS says as far as I know. Reduce the bus speed of the motherboard (you may need to play with the jumpers) Many bad motherboards work great with a 25 instead of 33MHz bus. Hope this helps. If I made no sense whatsoever it is probably because AI have been up for about 26 hours. If this is the case, I will try to trans;ate my message into English as soon as I get some sleep. ;-) >Even though everything is brand spankin' new, out of the box, I replaced >the DIMMS (64mb pc100 sdram), the chip a dreaded AMD K6/2 450, the NICs, >and removed UDMA from the HD.
