Arrived a little while ago this AMD-K6-2/533AFX, with this I would have all the frequencies from 233 to 550, except the 337 which is quite singular, and was used on IBM PCs with FSB 75, let's say it was the alternative to the CYRIX from AMD, it could probably hold up the comparison with the MII 400 or 433, however even the 533 is quite singular, because it uses a 97 MHz FSB, not all the cards have this particular setting, so either you put the jumpers at 95, or you overclockka at 100, corresponding to 550 MHz, which is the best for the K6-2 Normal, while the next version plus, came to 570 MHz.
The motherboard for which it is intended is the Compaq Camaro, I have to solve the problem (probably the BIOS must be rewritten), and replace the 475 CPU with this 533, unfortunately being without an integrated L2 cache, the performance is not the best, but this can be seen as soon as I have done the usual bench, even if the chipset of that MB does not promise interesting performance.
