Re: Best way to cool a 486DX Overdrive CPU?

As I'm currently do a 486 DX4-100 overdrive build, thought I'd share my own cooling solution. Because the case I'm using doesn't have a good place to mount an internal fan, I opted to put a 40mm fan onto the heatsink itself in a side-mount configuration. This moves air better through the fins under …

Looking for a proper PC speaker like the following to hear those classic PC speaker sounds from old games (Commander Keen etc).

Re: Intel DX4-100 Overdrive too fast in benchmarking?
Posted on 2024-01-04, 21:04
Is there some bug that can distort these numbers? Or something I can turn off in the BIOS to get the real benchmark speed? Just based on my own testing, changing the cache write timing from 1 WS to 0 WS resulted in changing the Norton SI CPU benchmark from 132 to 198. It also resulted in a general …

Just update to this issue. After updating the BIOS to v2.3, the motherboard now recognizes the CPU and the L1 cache is now active. I replaced the 486DX2-66 Overdrive with a 486DX4-100 Overdrive. The speed of the both CPUs massively increased!

LOL. Do we have first of April, because you are complaining that the system is too fast? SI is a synthetic benchmark, and does not say too much. I guess you are running the L1 in WB, so you have high values. AMD Am5x86@160MHz gives more than 300, so your values are not too high, don't worry. Use …

Fan size for old retro case

Apologies for this silly question, just want to double check before I order the wrong thing. I have an old PC case from 1998 that has screw holes for fans that are 70mm apart. Can you assume a 80mm fan has 70mm screw holes? I'm assuming the measurements are like the following? Filename Fan.png File …

So I measured the temp of my DX2-66 Overdrive and it sits at 57c. I haven’t measured my DX4-100 Overdrive so I’m guessing that will be just over 60c. I guess the temps seem to be ok but I think I’ll get a fan for the case. Would like these girls to last as long as possible.
