Hi, I've recently gotten an Alaris Cougar and supposedly it overclocks to a 33MHz bus for a 100MHz 486 Blue Lightning pretty well. But when I set the jumper for a 33MHz bus, it doesn't even POST -- does anyone else here have one doing that speed? How did you do it, is there something I missed?The 4C87DLC I have coming in the mail is rated for up to 40MHz. Do I also need to switch the jumper for the VLB to the other configuration? The manual says the current setting is fine for up to 33MHz, but anything faster needs the other config. I'm assuming it's configuring VLB wait states. My cache is 20ns but I can steal the chips off of one of my other boards, those are 12ns I believe, the board's a dying PC Chips M912 anyway so I'd argue it doesn't really deserve good cache...
I know I have a whole other socket for a faster CPU if I really want it, but I find the 486BL charming and feel like it'd lose a lot of its personality if I just plunk a 5x86 in there and make it just another "fast 486". However, I find the 25MHz bus to be a pretty big limit. Not only is it holding back my memory, it's holding back my VLB as well!
