Mine have 486DX33 without jumper, bus is fixed to 33Mhz, if you put a regular 486DX2 it work perfect at 66Mhz, no way to change the bus to 25 (and not need to do). In the manual i have read support 8k l1 and 128k l2. I have only one socket for normal (non overdrive) CPU.

It's not the size of the cache, actually. The problem is that all 486 CPUs with 16 kb L1 cache are using Write Back mode for it, unless you change it to WT in the BIOS (which you can't, since the BIOS does not know about it). The original AMD DX4 (not the enhanced one) should work just fine when …

As any of you will know I have among other things a Beautiful IBM PC 300GL minitower. I chose IBM because according to me it embodies the charm of those who gave birth to PCs. In the 90s and 2000s I avoided branded computers because at the same price they provided lower performance than an assembled …

386 and 486 are not far clock to clock, probably 386DX40 is much faster.

Good call on the model number - it's a 2155-G44. As for searching on processor upgrades, most of what I find relates to machines with the processor soldered in, whereas this one actually has it in a socket. I'd rather use the bog standard 486dx2 (5v, of course) if possible, since they seem cheaper …
