My first 486 from a few years ago. Thanks to parts found on AmiBay I'm going to give that machine an upgrade, to bring it closer to Pentium speed.
Have one overdrive and one DX5 133MHz chips in the mail that can potentially run with the motherboard, but won't know until they get here. Want to benchmark them against the current DX2-66.
Back in the 90's didn't have a 486, so I didn't know much about their motherboards. I did accumulate a few CPU's. Then when I got a 5V socket 3 I tried some CPU's and probably fried my 3.3V AMD's in the process. I did not know that DX4 series had a different voltage. Potential casualties are 2x 100MHz and 1x 120MHz AMD chips. Though there was no abnormal behavior. No chip overheating. No smoke. So maybe the CPU's or the board have protection against incompatible hardware. Either that, or they fried so silently, that I didn't even notice.
Does anyone know if inserting 3.3-3.45V CPU into a 5V socket kills it or if power is delivered via different pins, offering some kind of idiot protection. My board behaves as if it recognizes the wrong CPU type and refuses to power on entirely. Maybe it's a good sign. On DX2-66 and slower chips it runs fine.
