      From: willmurray461@gmail.com              That’s a bummer. I guess maybe 128MB is impossible. I was beginning to think       it was because I used 9-chip SIMMs with quad-CAS parity chips, but it seems       like you tried 12-chip parity SIMMs and yours still didn’t work. It’s       strange; I feel as though        stability decreases over time, but if you give the RAM sticks a rest, they go       back to being more reliable. Kinda like CPUs when they overheat/get       overclocked. I wonder if something like a memory controller could be       overheating (IDK if these boards have        such a thing)?              I’m just using the board how I got it for now (486DX2-66, no cache). For       storage I have a 2MB Spock with an IBM DPES-31080 HDD. I’ve tried other       CPUs in it though, with no change in reliability (Overdrive ODP DX2, 5x86 AMD       & Cyrix). Maybe I should        also test 25MHz vs 33MHz bus speeds though. I also bought a Pentium Overdrive       and 128kb cache module and they’re on their way, so if you’re curious       about comparing benchmarks I can do that too.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
