Intel DX2/DX4 Overdrive CPUs perform absolutely identical to the normal DX2/DX4 CPUs.

If you are running them on the same motherboard they should perform identically to their 'native' 3.3V counterpart. It's the same core after all. 😀 But running them on a motherboard with 3.3V support kind of defeats their purpose.

I would suppose the extra pin is meant to make sure the CPU is inserted correctly. Pin D4 is listed as 'Key' in the official datasheet.

Okay, So the extra pin has not other purpose than alignment ? I thought in the Overdrive socket it disabled the onboard CPU ?

Here are the benchmarks for the Intel 486dx4-100 CPU.

The score not only depends on the CPU itself but other things (chipset, RAM), see the "Ultimate 486 Benchmark Comparison" thread: an Intel DX4-100 WB scores 42. My own DX4-100 in WB mode scores almost that much. I bet if you compare a standard DX4 in WT with the overdrive version using the same …

Wich os is better for this kind of system? have 32Mb ram but i can reach 64Mb, trident 9400 and vlbus IDE controller. Win98SE will be too slow without advantage respect win95 on this computer? Tnks.

Go Win98 and remove all the extra unneeded crap of it. The better USB support is worth it. Failing that Win95 OSR 2.5. Ignore the original Win95 as it has no Fat32 support.

I've run Quake 1 and Grand Theft Auto on 386DX40 + FPU. Getting it to run and seeing it with your own eyes, is an achievement on it's own. I love to try those things out. I actually have win95 on my 386 for testing purposes... i think i can try quake 2 on it. :D (Looking at topic's heading, i think …

Hi! I'm a complete beginner in old hardware, just started restoring my first retro system (this particular computer also has a nostalgic value to me, so I want to be gentle with it). The problem I'm facing right now is that I bought an AT PSU, and I can't connect it to the motherboard. I Google for …
